The socio-cultural value of mangroves by Dr Dencer-Brown

The contents of this blog were written by Dr Imi Dencer-Brown and are presented by Amber Baker. Imi is on the ACES Board of Trustees and has studied mangroves and their cultural value in New Zealand as part of her doctoral research. Imi is a mixed methods researcher and lecturer in education working in cross-disciplinary spaces specifically with people and nature.

The socio-cultural value of mangroves – what’s it all about and why is it important?

“When we think of mangrove ecosystem services, we normally relate them to some of the more tangible concepts, such as the provisioning services of food and clean water for both humans and nature. We may also recognise their importance as regulating services, in the roles of flood prevention and protecting against storm damage. As the effects of climate change take their toll on ecosystems worldwide, we understand the plethora of positive attributes these intertidal forests provide, in particular, the enormous below-ground carbon storage capacity of mangroves, in the form of blue carbon.

Lesser known is the socio-cultural value of mangroves. The complexity of human existence and relationships with nature has been little explored in the large body of work of mangrove science, even though it may be pivotal to the deeper recognition of the socio-ecological importance of these ecosystems. Cultural services may include aspects such as cultural identity, sense of home, aesthetic inspiration and a spiritual experience in relation to the natural environment1. As some of these elements are intangible and complex to explain or quantify, it means that this area of research in relation to mangroves is under-researched and poorly understood.

There is such variation in the location of mangroves globally, which range from the United States such as Louisiana and Florida and the Japanese islands of Okinawa and Kyushu in the North, to the most southerly mangrove stands in New Zealand and South Australia. This variation in species and differing levels of degradation mean that humans interact with mangroves in different ways, based on their community needs and societal importance.”

Take New Zealand, for instance…

“Take New Zealand, for instance. Home to a monoculture of estuarine Avicennia marina subsp. australasica. Many of these stands are dwarf mangroves, growing and expanding in harbours and estuaries due to increases in nutrient levels brought about by urbanisation and farming practices. Many people regard these trees as a nuisance, nothing more than weeds, which have obscured the views of the beautiful beaches they had once enjoyed out of their windows.

Their ecological value is not recognised in many cases, making the relationship between humans and nature strained and not positive.”

“Previously, in New Zealand, mangroves were utilised for boat building and recognised as a valuable habitat for kaimoana (seafood) for local iwi (Māori communities).

Whilst some recognition of this may remain, the lack of utilisation and co-existing with mangroves in New Zealand has created a disconnection to nature and with it, a lack of understanding of the intrinsic value of this habitat.”

“Whilst New Zealand might be a very particular case of lack of socio-cultural integration with this ecosystem, many communities in the world do recognise the importance of this habitat to many aspects of human life., however, this has not prevented deforestation and degradation of mangroves globally due to anthropogenic activities such as replacement for aquaculture farms, construction of hotels, urbanisation and overexploitation of wood without sustainable forestry practices.”

Value and monetary value

“We tend to measure the value of goods and services provided by nature in monetary terms, this socio-economic value may be useful in driving forward conservation practices to restore and protect mangroves.”

Kenyan mangroves are said to be worth around 82 million pounds (200, 473.93 KSH/ha2). Whilst this is an impressive number – what does it actually mean? Where does the money go and how does it benefit local communities?

Dr. Imi Dencer-Brown

“Whilst valuing mangroves as a commodity in this way may influence policy on their conservation, it may not change understanding and awareness of this ecosystem, especially for the local people of the areas who have the closest relationship with mangroves.

In Kenya, the main drivers for loss are the excessive removal of wood for charcoal burning, fishing stakes, fencing and fuelwood, as well as conversion of areas for salt mining and settlement and coastal development. It is recognised in Kenya that poverty, inequalities, lack of education and poor governance have underpinned these losses.3

Communities living close to mangroves and have a high dependency on them for their livelihoods may have a greater cultural connection with these ecosystems and therefore have a high potential to work with conserving mangroves as they directly relate to their livelihoods.

The ongoing success of Mikoko Pamoja and Vanga Blue Forests projects in Kenya has been largely due to the direct stakeholder engagement with conserving these areas and seeing directly how improving the quality of habitat has a positive effect on livelihoods.

For instance, this may be in the form of increased numbers of juvenile fish using the mangroves as a nursery, which in turn allows for larger fisheries yields offshore, creating more sustainable income for families.”

“Mangroves are a cultural fabric to coastal communities, they support our livelihoods and beliefs, protect our homes and lands, and unite us with bordering communities.”
Mwanarusi Mwafrica, Previous Project Coordinator for Vanga Blue Forest

“Realising the importance and value that mangroves have for communities and respecting and upholding social justice frameworks to empower these communities to conserve and protect mangroves is a necessary step for the sustainable use of and long-term presence of this precious ecosystem in an evermore volatile world.”

We thank Imi for this blog and their insights on the importance of socio-cultural value of ecosystems, drawing from their experience and research in New Zealand. Like many plants that are often considered weeds or pests – based in Scotland, I am thinking of the humble dandelion – mangroves can be viewed in this negative light but upon further inspection, mangroves and other often overlooked species can provide valuable benefits to people and nature. – Amber

Meet a mangrove champion, a conversation between Mark and Ansumana

Mark: tell me where you were born and a little about your early life

Mark: and did you combine all this work with going to school?

Mark: so it sounds as if you were motivated even as a young boy to learn and to develop?

Mark: so how did you become interested in conservation and in mangroves?

Mark: how did you start Sankandi Youth Development Association?

Mark: and why did you start work on mangroves?

Mark: and that is how you found out about ACES?

Mark: and now after some years we have managed to find funding for this work and are in a position to work together on this new project. What are your hopes for the future from this work together?

Mark: and finally, do you have any advice for anybody who may be reading this, who perhaps is in a similar situation to you?

Ocean Bottle: Supporting blue carbon beyond offsetting

Ocean Bottle: Supporting blue carbon beyond offsetting

This blog was written in collaboration with Ocean Bottle, who have supported ACES’ projects for several years as part of their commitment to improving the health of the ocean and our planet. This blog was written as part of our ‘financing blue carbon ethically, responsibly and effectively’ series and explores different approaches to compensating for corporate carbon footprints and supporting marine conservation.

Ocean Bottle have supported ACES’ mangrove and seagrass projects for several years as part of their commitment to making the ocean, and our world, a better place. Ocean Bottle’s approach to sustainability goes beyond carbon calculations and ‘net zero’; that equating carbon emissions to offset purchases is inadequate. In line with this ethos, they are moving beyond carbon offsetting to a holistic approach to carbon reductions and developing carbon sinks by protecting natural ecosystems such as mangrove forests and seagrass meadows. This blog, written in collaboration with Ocean Bottle, explains the reasoning behind their strategy for emissions reductions and compensating for their unavoidable emissions. Ocean Bottle’s reasons for moving away from offsets include ethical, political and technical challenges to offsetting as a concept and the current offsetting landscape; this reasoning is described well in this document. Here, we focus on the political ethics of carbon offsetting, which raises important questions regarding how the offsetting landscape can be improved in order to incentivise systemic change.

The perspectives presented here are Ocean Bottle’s; however, as ACES, we welcome debate around carbon offsetting and support Ocean Bottle in their emissions reduction strategy. We are pleased to be able to continue working with Ocean Bottle on the development of blue carbon conservation and restoration activities in a way that goes beyond carbon credits.

Emissions reduction strategy

Ocean Bottle’s Emissions Reductions strategy follows three pillars: first by implementing emission reductions through their supply chain, then avoiding emissions in their value chain, and when necessary, developing carbon sinks by protecting natural ecosystems outside of their value chain. This follows the Carbone 4 emissions reductions framework.

While this framework is broadly similar to the ideal scenario for offsetting – reducing your scope 1 & 2 emissions, then scope 3 emissions, followed by offsetting or insetting unavoidable emissions – the biggest differences lie in pillar C.

Firstly, under Carbone 4’s framework, unavoidable (or residual) emissions should be compensated for through the development of carbon sinks such as blue carbon ecosystems. This is similar to ‘removal credits’ – carbon credits that result from the removal of CO2 from the atmosphere – but does not allow an equivalent to ‘reduction credits’ – credits which result from the reduction of CO2 entering the atmosphere. (It is important to note here that removal credits are also sometimes valued and preferred over reduction credits – such as in the Oxford Offsetting Principles).

Secondly, Carbone 4’s framework does not specify that offsets should be used to compensate for unavoidable emissions; it allows for a broader approach to funding activities that enhance natural carbon sinks. This is where Ocean Bottle’s perspective has changed from buying carbon offsets to a more holistic approach to enhancing blue carbon sinks.

Choosing carbon sinks over offsets

If Ocean Bottle are committed to funding the development of carbon sinks like mangroves and seagrass, why are they moving away from offsetting?

Offsetting as a concept has been heavily scrutinised, and the debate around the politics and ethics of offsetting has divided opinion. Critics of offsetting question whether offsetting allows society to delay making systemic changes – i.e., actual carbon reductions – by simply paying for offsets to compensate for carbon emissions. Whilst the morally responsible approach should be to first reduce your direct and indirect emissions as far as possible – as outlined in Carbone 4’s framework – there is nothing to mandate companies to do so (or indeed, to reduce or offset their emissions at all). Likewise, there is no regulation of how companies present or communicate their carbon reductions – a company that offsets all of their emissions without making reductions can report the same emissions reduction targets as a company that has made genuine carbon reductions in their own activities and supply chains (and has therefore contributed to systemic change). Actors in the offsetting market, including ACES, can and do take voluntary steps to guard against this injustice; however, Ocean Bottle’s perspective is that they do not want to play a part in a system that permits less ethical companies to take advantage of unregulated emissions reductions and reporting.

The reporting and carbon reduction strategy enforcements vary from country to country, but are, for the most part, only voluntary. This means that sub-par efforts and greenwashing by the world’s largest emitters will largely go unpunished.

Ocean Bottle

This raises an important question: what can be done to hold companies to account on their emissions reductions and offsetting (or other mitigation actions)? How can companies with genuine commitments to actually reducing their emissions, offsetting only their unavoidable emissions and if they do need to offset, researching their options and choosing high-quality credits with evidenced co-benefits – from companies that simply ‘pay to pollute’ by offsetting without reducing? There needs to be a clear, internationally-aligned reporting system under which consumers can scrutinise the steps that companies are taking to lower their carbon footprints, and thereby hold these companies to account. This would be a significant step towards facilitating systemic change – publicly rewarding companies like Ocean Bottle that go above and beyond to not only compensate for their emissions but have a positive impact through supporting projects that deliver biodiversity and community benefits.

Net zero: a global concept

By definition, a company cannot be carbon neutral… A better terminology which companies and individuals should follow, is to contribute to global neutrality with the purchase of offsets and other mechanisms.”

– Ocean Bottle

When the concept of ‘net zero’ was popularised in the conception of the Paris Agreement, it referred to global emissions – achieving an overall balance of sources and sinks of global greenhouse gases. It is only more recently that the term ‘net zero’ has been used by companies as a label of their emissions reductions or offsetting. Ocean Bottle, among others, believe that the concepts of net zero or carbon neutrality cannot be claimed by individual companies unless they are actively sinking carbon from the atmosphere – if they are still producing emissions then they are still a carbon ‘source’, regardless of offsets. Ocean Bottle suggest that rather than making ‘net zero’ or ‘carbon neutral’ claims, companies should use terminology such as “contributing to global neutrality with the purchase of offsets and other mechanisms”. They believe that not being able to trumpet about self-proclaimed neutrality will deter most companies from relying on offsets.

ACES perspective

Ocean Bottle’s approach to their emissions reductions is a gold-standard example of how companies can meaningfully engage with the climate crisis and their role in fighting it. They have critically questioned their own activities, including their emissions reduction activities so far, and shaped their way forwards based on extensive research and evidence-based perspectives.

Whilst their full reasoning for minimising their use of offsets is not always fully aligned with ACES’ views, we welcome debate regarding the ethics, politics, effectiveness and social justice of offsetting and our partnership with Ocean Bottle allows us to present this diversity of views on an open platform. Ultimately, we and Ocean Bottle share the same end goal: to contribute to a landscape in which climate action by companies is transparent, genuine, effective and socially and environmentally just.

Philanthropy and climate change: A conversation with Impatience Earth

Philanthropy and climate change: A conversation with Impatience Earth

A profile photo of Yasmin Ahammed of Impatience Earth

Impatience Earth is a pro-bono climate philanthropy consultancy that educates, challenges and inspires wealth holders to take bolder funding decisions to address the climate emergency.

We interviewed Yasmin Ahammad, the Co-Managing Director of Impatience Earth to gather her insights on climate philanthropy and understand what influences donors when they are considering which projects to fund. 

Here’s what Yasmin had to say… 

1. What motivates philanthropists and foundations to fund projects that tackle climate change? 

The public’s awareness of the climate crisis has skyrocketed in recent years, thanks to the tireless efforts of climate activists and the growing coverage of alarming IPCC research findings. As heat waves scorch entire cities and floods devastate communities, the reality of climate change hits closer to home more than ever before. Urgency has become the driving force for philanthropic donors to invest in the fight against climate change, and their support is crucial to creating the change and momentum we need.

At Impatience Earth, donors typically approach us with a keen understanding that the climate crisis is the most pressing issue of our time. They recognize that the impact of climate change will undo many of the gains made in other areas such as health, education, conservation, social justice, and human rights. These individuals, foundations, and companies feel a collective responsibility to act while there is still time to avoid the worst climate scenarios. They may support climate change as a new strand of their grant-making or incorporate it as a lens through which they view their existing projects.

“We have seen a particular interest in mangrove and other blue carbon projects like seagrass and saltmarshes, because it is easy to understand the numerous co-benefits of investing in such nature-based solutions.”

Why philanthropy and what inspires philanthropists right now?

Philanthropy is uniquely positioned to act because it can provide the seed capital for bold and innovative movements, ideas, and initiatives to experiment, scale, and thrive. Unlike government or corporate institutions, philanthropy can afford to take risks and fund projects flexibly and nimbly, filling critical gaps in support.

We have seen a particular interest in mangrove and other blue carbon projects like seagrass and saltmarshes, because it is easy to understand the numerous co-benefits of investing in such nature-based solutions. Donors focused on reducing carbon emissions are attracted by the carbon sequestration potential of mangroves and seagrasses, while those who are passionate about biodiversity are motivated to protect and restore coastal ecosystems for the benefit of marine species. Donors with a focus on building community resilience find mangroves appealing as a natural barrier to disastrous storm surges and coastal erosion, and as a source of livelihood opportunities through eco-tourism, healthy fisheries and potential access to carbon markets. 

“We have seen a particular interest in mangrove and other blue carbon projects like seagrass and saltmarshes, because it is easy to understand the numerous co-benefits of investing in such nature-based solutions. Climate justice, land rights, youth, and women’s rights are popular cross cutting concerns, while policy, capacity building and conservation are key approaches.” 

Aside from blue carbon approaches, we see a lot of appetite amongst our clients to learn about other carbon sinks such as peatlands and forests, followed by agriculture and food systems as a whole. Climate justice, land rights, youth, and women’s rights are popular cross cutting concerns, while policy, capacity building and conservation are key approaches.      

2. What influences philanthropists’ / foundations’ decision making when assessing quality of projects in terms of how they gauge climate impact, but also co-benefits?

Each donor is different in how they assess which organisations or projects to fund, and how stringently they set the criteria. But generally speaking, they share a few common questions that help them assess the quality of a project:

How well does it align with our philanthropic mission and values? 

If climate justice is a core value of the donor, for instance, they will assess the project based on whether it advances climate justice by putting more power and resources into the hands of those most affected by the climate crisis. Similarly, if they care deeply about biodiversity, they will want to make sure that the project is led by experts who can advise on planting the right trees in the right way to benefit the local ecosystem.

What is the impact of the intervention?

Donors will consider the project’s potential to create positive environmental and social outcomes, depending on their core concerns, whether that be reduction in carbon emissions, or the extent to which communities have ownership and gain benefit from the project. Some donors like hard metrics to demonstrate the impact of the project, such as total carbon sequestered over time, number of trees planted, number of jobs created, or the percentage change in community attitudes towards mangrove restoration. While these example metrics are useful, we try to educate donors that impact measures are best defined by the project leads and communities themselves, so that they are monitoring and reporting what is most useful and important to them. 

What is the sustainability of the project?

Philanthropists will consider whether all the conditions are in place to ensure that the mangroves will be thriving and delivering their benefits long after they have stopped funding the project. This includes having the right tree species and planting methods, community buy-in through education and alternative livelihood opportunities, and a clear plan for ongoing funding, whether through donations or income.

What is the track record of the organisation?

Donors will look closely at the organisation or individuals leading the project to assess their expertise and capacity to successfully implement the project. They might do this by reviewing impact reports, holding short interviews with the project leads, or reaching out to other funders for references. 

3. Following on from the above: what information can practitioners make available, and in what format, to better showcase their projects and help this decision-making? 

In the process of making a decision, clear communication materials are essential. Donors usually start by checking out a website before they even consider asking for a proposal. That is why it’s a good idea to include compelling materials that showcase the impact of your work. 

Telling captivating stories and providing clear impact metrics are crucial to demonstrating the project’s effectiveness and track record. It’s also important to include financial information, such as the organisation’s annual budget, so that donors can determine whether their usual grant size is too much for the organisation to handle or whether they are better set to make a small contribution to a larger pool of resources. It’s also important to highlight the individuals who are behind the project, their skills and backgrounds, and to make their contact information publicly available so that donors know who they can reach out to with any questions. 

If and when invited for a proposal, then pay close attention to the guidelines, especially on the maximum pages they would like. I’ve learned that philanthropists and small foundations typically have very little time to make a number of complex decisions, so the easier you can make this process by being succinct and clear, the better. 

.

4. Moving away from philanthropists and to Impatience Earth – who are you, and what services do you provide?

“We see ourselves as climate knowledge and relationship brokers – helping donors access the incredible array of climate expertise of practitioners, activists, and academics to help make sense of the climate emergency in a way that resonates with them.”

We are a small team of advisors with backgrounds in climate change, biodiversity, international development, social justice, philanthropy and entrepreneurship. We are incredibly passionate about what we do, and how we see our work contributing towards a much more equitable world for everybody. We set out in 2020 to increase the amount of philanthropic capital being directed to climate change, but we also want to see funding going to actors who have been traditionally overlooked and underfunded, and to help shift philanthropy towards a more trust-based approach and in support of climate justice. 

We see ourselves as climate knowledge and relationship brokers – helping donors access the incredible array of climate expertise of practitioners, activists, and academics to help make sense of the climate emergency in a way that resonates with them, and then move forward on acting on climate with confidence by helping them develop strategies, and connecting them to co-funders and potential grantees. 

The learning journey is a central component of our work, which is a bespoke series of intimate sessions with experts where they can dive deep into a subject area and ask lots of questions. We’ve found that learning is critical; clients who want to skip the learning and go straight to recommendations on who to fund don’t seem to end up committing to climate in the long-term. 

5. What are the most common questions that you are asked? Have any common themes emerged that you think need to be better answered/communicated by practitioners?

The most common question we hear is “where can we best make an impact?”

In the climate emergency, there is no straightforward answer to this question, because it is a complex global systemic crisis. Unfortunately this is where a lot of potential donors to climate change get stuck, because it seems so overwhelming, when in fact there are so many ideas, initiatives and approaches in need of funding that will collectively deliver the change we need. 

We help each client craft an answer to this question that makes most sense to them through learning and reflection. There are a number of factors that will influence the answer, such as what values are core to the foundation, where they are drawn to funding geographically, where they think change comes from (e.g. top-town, bottom-up, or both), and which sectors and approaches resonate most with what they have supported so far and want to focus on in future. 

For practitioners seeking funding, it is important, unsurprisingly, to help funders clearly understand how their grants will make a difference. This stems from you understanding the broader change you are working towards in the climate context and beyond, whether it’s building long term community resilience, strengthening local biodiversity or building the movement for climate justice. While it’s important to outline the how (activities) and the why (the problem statement) to demonstrate your capabilities in planning a project, it is the outcomes that will inspire donors to invest in you and help them realise their own impact.

Carbon offsetting: Is it greenwashing?

Carbon offsetting: Is it greenwashing?

Part of 2023 blog series: Financing Blue Carbon Ethically, Responsibly, and Effectively

Pressure is growing on businesses to show their environmental credentials, and as part of that, tackle their carbon emissions. Claims of ‘carbon neutral’, ‘net zero’ and even ‘climate positive’ are being used more and more by businesses keen to play their role in tackling the climate crisis – or at least look like they are. How can we tell which have make genuine and meaningful commitments and progress, and which are simply hiding behind confusing and obscure terminology?

When a business makes claims such as ‘carbon neutral’, ‘net zero’ or similar, it’s important to know exactly what that means.

Reducing a carbon footprint can be achieved in two ways: by reducing the emissions that your activities cause (such as driving or flying less, switching to renewable energy sources, or eating less meat) or offsetting emissions by paying for activities elsewhere that either reduce emissions or sequester (absorb and trap) greenhouse gasses from the atmosphere.

These two strategies are not equal. Reducing our emissions is vital – the average carbon footprint of a Western lifestyle is unsustainably high, and systemic change is needed in order to avoid catastrophic climate breakdown. However, the transition to a low-carbon society is incomplete and reducing emissions is not always possible. Offsetting should only be used to compensate for these remaining emissions – or ‘unavoidable carbon’ – that cannot yet be reduced.

Whether a company reduces or offsets its emissions makes no difference to how their claims to carbon neutrality can be presented. Take two businesses: one of whom has transitioned to renewable heating sources on-site, swapped their fleet of petrol gars for electric vehicles and eliminated all business travel by plane or car; the other has made no changes to their business but has paid to offset their emissions. Both can make the same claims to have reduced their carbon footprint, despite the first business having invested more time and resources into achieving that reduction. This does not incentivise systemic change and can potentially mislead consumers into believing that a business is taking meaningful climate action. Offsetting has been criticised as a cheap and easy alternative to make systematic change; we strongly believe that they should not be used in this way and organisations should be transparent about how they have reached ‘net zero’ and commit to ongoing carbon reductions to reduce the need to offset.

However, the scenario above is binary – the ‘gold standard’ of doing everything possible to reduce, versus doing nothing at all and just buying offsets. The latter scenario is often used by critics of offsetting, claiming that offsets are cheap, quick and easy way to claim carbon neutrality. Unfortunately, there is nothing stopping companies from doing this – and there are certainly companies using offsets to make environmental claims whilst still contributing to climate change. However, our research has found that among our buyers, the reality is much more nuanced and that offsets are seen as one step in the path to ‘actual zero’ emissions: a necessary step for now but not a long-term strategy.  

Rather than thinking of companies as ‘perfect’ or ‘evil’ when it comes to carbon reductions, it is helpful to consider more realistic scenarios. Where is the line drawn between avoidable and unavoidable emissions? For example, the upfront costs of electric cars, heat pumps, insulation and other carbon-saving strategies are expensive, and government incentives are not always available. If a company or individual chooses not to opt for these on the basis of cost – even if they are a small, low-budget business – can the emissions really be counted as avoidable? Purists may say yes – that if you can’t afford to avoid the emissions, you should stop contributing to them altogether. In reality, this is unlikely to happen. Businesses need to stay afloat, people need their livelihoods, and in many cases businesses will (have to) opt for the most cost-effective option for them. There are instances when the burden of carbon reductions is too much to expect of individuals and even businesses – it is where strong, effective policies for carbon reductions are needed.

ACES believe in the ‘3 Ps’ as the principles for tacking the climate change, in order of importance: firstly, political change is needed; secondly, personal (and corporate) carbon reductions should be made, and lastly, paying to offset should be a last solution for emissions that cannot be reduced.

It is also important to consider the value of a carbon offset. Carbon credits are generated by activities undertaken to reduce the amount of carbon entering the atmosphere or remove emissions that are already there. They can be achieved by generating renewable energy, by changing land management practices such as farming methods that result in the release of carbon dioxide, by protecting and restoring forests, and other interventions that result in a ‘carbon benefit’. The diversity of these projects means that the offsets that they generate can mean anything from the financing of a large-scale wind farm with little community benefit, to funding grassroots forest conservation with community development at its core. This diversity brings with it a range of prices – from as little as $0.20 to $50 (and more) a tonne – and the price paid by the buyer may indicate their commitment to supporting projects that go above and beyond carbon, benefitting the wider environment and local people. Read more about how not all offsets are created equal here.

There is therefore a role for offsets in broader carbon reduction strategies and claiming ‘net zero’ in itself is not greenwashing. However, consumers should be aware of what this means and what a company can disguise with that claim, and businesses should make genuine and meaningful progress to reduce their carbon emissions before offsetting. It should be recognised that their ability to do so is, however, dependent to some degree on policies and government support to incentivise and enable them to reduce their emissions – while personal and corporate reductions are important, they come secondary to policy in their role in global carbon reductions. Businesses should be transparent about their commitment to ongoing carbon reductions and wider sustainability, and how their use of offsets contributes to their carbon reduction strategy; in doing so, allowing consumers to make informed judgements on their environmental credentials.

Not all offsets are created equal

Not all offsets are created equal

Not all offsets are created equal: what are “high quality carbon offsets”?

Our clients sometimes ask us what the difference is between carbon credits that they can buy for $5 a tonne, and those that cost $10, $50 or even more per tonne. Why pay more for the same outcome – a tonne of carbon sequestered?

Like all other products and services, carbon credits can vary widely in their quality. But what does this mean, and how can you tell a “high quality” offset from the rest?

Whether you pay $5 or $25 for a carbon offset, the outcome (for you) is the same: you can claim that you have offset that amount of your carbon footprint. However, there is much more to the process than this “behind the scenes” – including who benefits from the project interventions, what safeguards are put in place to ensure that local people are not disadvantaged, and how longevity of the carbon storage is ensured.

Any certified project – and we encourage buyers to look for certification when offsetting – must meet the requirements of carbon standards that set out how projects should operate, including calculating the carbon captured, how the community should be engaged, and how socio-economic factors should be considered. This means, on paper at least, that high standards are maintained. The principles and values vary between standards; for example, the Plan Vivo Standard places particular emphasis on the socio-economic development of less-developed nations and allows for flexibility in project design that enhances accessibility for small projects.

Certification is not failsafe, however: certified projects have been criticised on the grounds of human rights breaches, failing to ensure long-term carbon storage, and providing no carbon benefit beyond what would have occurred anyway. These criticisms are more common in the compliance carbon market than the voluntary market that we are part of (see here for an explanation of the two and their differences), however as project developers and carbon buyers, we need to ensure that these failures are not perpetuated in the projects that we run and choose to support.

So, what should buyers look for in a project?

Projects should be able to demonstrate how they engage with, involve and benefit the local community, and be able to provide evidence of this. Community consultations are a start, but are local people given opportunities to work for and govern projects? Does the project deliver financial, infrastructure or other tangible benefits for local people? How does the project monitor and act on adverse impacts on the community such as reduced access to timber? What power does the community have in decision-making? Community involvement is vital to project sustainability – carbon projects are often sited in developing nations where natural resource reliance is high, and if the needs of the community are not met the project risks alienating, disadvantaging or even displacing people, or failing altogether.

Carbon offsets are generally expected to be “permanent” to at least 100 years – that is, carbon that is stored should be locked away for at least a century. Of course, we cannot guarantee this; no one can truly say what will happen in 100 years’ time. ‘Permanence’, as it is known, is assessed on a number of factors including how the project addresses drivers of degradation and potential “exit strategies” for if and when the project comes to an end. Buyers should look for meaningful action by project developers to ensure that the stored carbon won’t be at risk as soon as the project ends. Does the project enhance environmental education? Are local people empowered to manage their local resources? Does the project address the core reasons for the loss of carbon, such as poverty that drives people to cut timber for firewood? While we cannot guarantee the future, actions such as these improve the chance that damaging activities won’t just return to normal at the end of the project.

Carbon is of course the core feature of an offset, but it doesn’t have to be the only one. Projects can deliver community development benefits such as funding education or providing water, enhancing biodiversity, or helping local people to develop more diverse livelihoods to ease the pressure on natural resources and provide jobs to local people.

We encourage buyers to explore projects Project Design Documents (or PDDs) – these should be available through the standard to which a project is certified and contain detailed information on how a project is structured and operates. Ask to speak to those in charge of the projects (at ACES, we are always happy to have a conversation with buyers and prospective buyers, whether you’re looking to buy 1 tonne or 1,000 tonnes). Developers should be transparent about their projects, including on how money is spent – some projects are worth paying a higher price for, but you should be confident that if you choose this option, your money is being spent well.

Critics of offsetting point to examples of bad practice in carbon trading projects as reason to avoid offsetting altogether. The carbon trading world is not immune to misguided or even malevolent practices that have resulted in miscarriages of justice for people or for the climate, and project developers and carbon standards should and do learn from these to prevent them from pervading in the industry. Carbon buyers should be aware of the diverse perspectives on offsetting, but also should be able to make informed decisions at a project level when considering offsetting so that they can support valuable projects that deliver not only carbon reductions, but broader benefits for people, wildlife and the environment.

In the last 10 years or so, mangrove forests have undergone a reputational shift that any PR agency would be proud of. Once dismissed as malaria-ridden swamps, mangroves are now recognised as the coastal superheroes that they really are. Seagrass meadows are also increasingly recognised for their environmental importance, and even saltmarshes – perhaps, unfortunately, less charismatic than their coastal cousins – are receiving attention for their carbon storage abilities. These three ecosystems together are the three main ‘blue carbon’ ecosystems[1], and their collective ability to contribute to the mitigation of and adaptation to climate change is huge in relation to their area.

This newfound fame is cause for celebration – we protect what we love, and blue carbon ecosystems deserve all of the love they can get. Mangrove, seagrass and saltmarsh scientists and conservationists who have been singing their praises for decades are now joined by a tidal wave of interest from people wanting to contribute to their protection and restoration. On the face of it, this is good news for blue carbon conservation, yet this excitement brings a risk that the quantity of support may come at the expense of quality of work that it funds.

Take, for example, planting mangrove trees. People love to see mangrove saplings being stuck in the ground, muddy hands and feet working hard to plant seedling after seedling, filling bare gaps along the coast with a future forest. Yet mangrove planting is notoriously fickle – one 2015 study suggests that only around 50% of mangrove planting efforts succeed to become established forests. Wave erosion, suffocation by sediment and grazing by goats are among the biggest threat to these newly planted trees, which often lack the protection of a surrounding forest which new seedings need to thrive. This challenge is not well-known outside of conservation and science, however, and funders keen to finance the planting of mangroves may end up throwing their money at efforts that may well fail.

Expectations of what blue carbon can deliver, in what timescale and with what budget must also be managed. Projects that are certified to sell carbon credits generated from mangrove planting and protection take time, energy, patience and resources to develop. For this reason, they are few and far between – fewer than 10 projects worldwide at the end of 2022 – creating a huge mismatch between supply and demand for ‘blue carbon credits’. Funders must recognise the need for upfront financing to get these projects off the ground, and allow for flexible, iterative approaches to project development that mean that the communities involved can be meaningfully consulted and involved, which may ultimately mean a deviation from the original proposal to the funders. This community engagement and involvement is crucial, however, both in the project development phase and throughout the lifespan of the work. Project developments must meaningfully engage with community aspirations, needs and perspectives to ensure social justice in the project interventions and benefits. Our first blog will present findings from research into perspectives of justice among the community of Vanga, home to our Vanga Blue Forest project. Through quotes from research participants, we will present the findings through the eyes of the community, highlighting the nuances of what social justice means to those most impacted by the projects.

Carbon credits may be a solution for some communities wanting to protect and restore mangrove forests, but it is not a solution that is suitable for all. The resources, skills and equipment needed to develop these projects is beyond the capacity of an average community group, meaning that there is almost certainly going to be a reliance on scientific and technical partners, which may well come at a cost. Nearby scientific facilities may ne needed for processing of samples and for scientific and technical support for project staff – something that is not always available in remote areas. For these and other reasons, significant stumbling blocks can lie between community groups and carbon certification. This challenge should be recognised and funders should consider the possibility of grant funding to unaccredited projects, rather than or in addition to buying carbon credits. This approach has been taken by Ocean Bottle, who have diverged from offsetting their carbon footprint to funding high-quality projects that fund the conservation and restoration of carbon sinks, including blue carbon ecosystems. Later in the year, Ocean Bottle’s blog will expand on their approach to financing blue carbon as part of their environmental and social responsibility as a marine-focused business. 

Whether funding comes from carbon credits, grant funding, philanthropy or other sources, the ethics of where the money comes from and what role it plays in the funder/buyer’s carbon reduction, CSR or philanthropic strategy is important. Funding blue carbon conservation shouldn’t be a distraction from taking steps to make systemic change or reducing carbon emissions or to cover up harmful or unethical practices elsewhere. It should be well-informed and researched, although donors do not always necessarily have the time, knowledge and capacity to carry out this research. For businesses, many sustainability consultants are available to provide this support, particularly regarding carbon reductions and offsets. In the philanthropic landscape, Impatience Earth provide pro-bono advice to philanthropic trusts who are interested in making donations to organisations to tackle the climate crisis. In April, we will publish a blog from Impatience Earth discussing their work, including what motivates philanthropists to find climate change work and what influences their decisions when directing this funding.

This recent ‘blue carbon boom’ provide great opportunities for the conservation of mangroves, seagrass, saltmarsh and other marine ecosystems, if directed appropriately and informed by the lessons learned from the protection and restoration of blue carbon habitats so far. Our upcoming blog series, with contributions from Ocean Bottle, Impatience Earth, the community of Vanga, and also researchers into the future of carbon financing, will address key topics and questions needed to help to direct this funding.

Our first blog, Voices from Vanga, will be posted on 28th February. If you would like to be signed up to our mailing list to receive this, drop us a line at [email protected].
