Carbon offsets and forests

 


 

According to the Corporate Finance Institute, a carbon offset “refers to the units earned by firms that have implemented a greenhouse gases reduction project. It is issued by a board or government authority, and one offset credit is given for every ton of greenhouse gas that is reduced, stored, or avoided.” These offsets may then be sold “to an investor, government, or NGO to offset their emissions or for investment purposes.” The market for such offsets “enables private investors, governments, non-governmental organizations, and businesses to voluntarily purchase carbon offsets to offset their emissions. The largest category of buyers comprises private firms that purchase carbon offsets for resale or investment” (CFI, 2021).

Blaufelder et al., (2020) claim that “Natural climate solutions (NCS), a category including project types such as reforestation, avoided deforestation, improved forest management, and agroforestry, have grown faster than any other project category and contributed significantly to the voluntary carbon market’s growth trajectory.” It is carbon offsets related to forests with which we are here particularly concerned.

Streck (2021) states that nature-based solutions alone – “in particular efforts to reduce deforestation and restore natural forests, opportunities that are concentrated in developing countries” – could provide “about 30 per cent of the total needed to achieve the Paris climate goals”, and that “a significant share of the required investment can be mobilised via projects and programmes accredited under voluntary carbon market standards.” Reducing emissions from deforestation and forest degradation is an important form of nature-based solution, given the acronym REDD; when conservation, sustainable management, and enhancement of forest carbon stocks are included the acronym becomes REDD+. Streck points out that “voluntary carbon standards already provide a framework for collaborative efforts” to achieve REDD+ aims, and can overcome concerns over “company greenwashing”. She argues that these standards allied to corporate accountability and public policy can manage the risks inherent in offsets and give them credibility, and lists the leading standards as the Verified Carbon Standard (Verra), the Gold Standard, the Clean Development Mechanism (CDM), the Climate Action Reserve and the American Carbon Registry. Criteria common to these standards include the setting of reference levels for emissions; monitoring, verification and certification; co-benefits, participation and consultation; and ‘additionality’, the assurance that the desired project outcomes would not have happened anyway. In her conclusions, she notes that well designed projects “can empower communities and increase their agency in the national policy dialogue”, but also that despite their importance, carbon markets “remain a transitory strategy”. This is because government regulation should in time enforce GHG reductions, so that “fewer and fewer projects should be able to pass the additionality threshold”. The carbon market can smooth “the transition towards a low-carbon future” and act as “an incubator for innovation” but should eventually have no function. Streck is a Co-Founder and Director of the international advisory company and think tank Climate Focus.

Seymour (2020) provides examples of reforestation projects by Shell, Mastercard and Microsoft in “an already crowded field of initiatives”, noting that “history and science caution that the impacts of tree-related interventions depend on a host of social, political, and ecological factors”. She lists some of the difficulties encountered by earlier schemes: social and ecological issues were ignored, livelihoods disrupted, and ecosystems damaged by the planting of non-native species; projects failed because the underlying causes of forest loss were not taken into account. Lessons learned are “informing a more sophisticated practice of forest landscape restoration (FLR)” which prefers the use of native species and encompasses “activities focused on local livelihood and resilience objectives such as agroforestry (incorporating trees into agricultural cropping) and regreening (farmer-managed natural regeneration).” Natural regeneration may be more effective than plantations for meeting climate objectives. The objectives of the forest-restoration movement go beyond “either timber production or carbon storage”, and can include “diversifying local incomes” and “establishing wildlife corridors”. Seymour regards the most important option of all as “protecting forests that are still standing” and points out that “avoided emissions now are more valuable than removals later” since planting trees will “pull carbon out of the air only gradually over the course of decades.” The term ‘irrecoverable carbon’ refers to carbon which if released from an ecosystem, could not be recovered by restoration before 2050. It has been estimated that “tropical moist forests have the largest irrecoverable carbon stock, but peatlands, mangroves, and old-growth temperate forests are also significant.” Seymour concludes that “the new corporate interest in trees is welcome because an all-of-the above strategy is necessary to avert catastrophic climate change.” However for initiatives to have maximum effect they should build on the insights of the forest landscape restoration movement, and include commensurate support for maintaining existing forests. Seymour declares her interest as board chair of the Architecture for REDD+ Transactions; she is also co-author of the Center for Global Development online publication Why Forests, Why now? (Seymour and Busch, 2016).

Fleischman et al. (2021) refer to the recent growth of ‘forest carbon finance’, funding for forests to absorb more carbon. While accepting that forests can mitigate climate change in this way, they note growing evidence that “forest carbon finance often undermines the livelihoods and autonomy of forest dwelling communities, damages natural ecosystems, decreases biodiversity, and does little to store carbon.” Two case studies are presented, a ‘successful’ one in the USA, and an ‘unsuccessful’ one in India. The writers argue that political factors explain the difference in outcomes. The American study relates to part of the traditional homeland of indigenous Yurok people in northern California. The Yurok sought to regain control of “ancestral territory, as well as to restore culturally important landscapes and ecosystems” and funding for carbon storage helped them to achieve this. There has been a resultant decrease in timber harvesting and reduction in fire risk, and “the project is expected to result in significant additional carbon storage.” The Indian study refers to programs “implemented through state forest departments that have a long record of poor performance with regards to forest conservation, afforestation, reforestation, and respect for the rights of the millions of forest-dependent people in India.” The paper analyses the political factors which have affected the outcomes of the two studies, particularly the importance of “forest-dependent people living in or near forested areas”. It concludes that schemes can work, listing criteria for success, and claiming that political reforms that “secure land rights for indigenous and forest-dependent people are strongly associated with improved forest cover and condition … and represent a powerful opportunity to store carbon, protect biodiversity, and enhance the well-being of the rural poor”.

Controversies over forest protection offsets are illustrated in an article by Greenfield (2021), who begins by claiming that the “forest protection carbon offsetting market used by major airlines for claims of carbon-neutral flying faces a significant credibility problem”. Investigations by the Guardian and Unearthed “found that although many forest projects were doing valuable conservation work, the credits that they generated by preventing environmental destruction appear to be based on a flawed and much-criticised system”.  A central problem is that credits are calculated on the basis of predicted emissions prevention, and “were often inconsistent with previous levels of deforestation in the area” and may have been overstated. Greenfield acknowledges that “there has been work to address this fundamental issue”, and that the results of the investigation “have been fiercely criticised” by Verra, the American non-profit organisation which “administers the world’s leading carbon credit standard”. He refers to the concerns of several subject experts: one “found that projects had routinely overstated their emissions reductions”, and another said that “although Verra methodologies for claiming credits were a serious attempt to measure emission reductions from reducing deforestation, they were not currently robust enough”. Others believed that “projects have a tendency to inflate threats to the forest” and “it was difficult to judge if the emission reductions claimed by projects were real”. Verra acknowledged “that many of the benefits provided by these projects were difficult to measure”, but Global Forest Watch defended “the usefulness of conservation finance mechanisms”.  While Verra “believes strongly in its Redd+ programme”, Greenfield points out that the “intense disagreement over the global carbon market that would underpin Redd+ and other climate mitigation systems has meant it is the only part of the Paris agreement rulebook that governments are yet to agree.” He notes that the growth in “corporate net zero strategies and carbon neutrality claims” increases the need for “rigorous and accurate” calculation of the emissions reduced by forest protection offsets, gives examples of “an inconsistent use of predictive methods and tools” in existing projects, and refers to a study by West et al. (2020) which suggested that “the accepted methodologies for quantifying carbon credits overstate impacts on avoided deforestation and climate change mitigation.” Greenfield reports that “Verra is making substantial changes to the way projects generate credits to comply with likely changes if disagreements over the Paris agreement rulebook covering nation-level Redd+ are resolved” and “has developed a new risk-mapping tool to highlight areas most at risk of deforestation.”

Few issues in climate change mitigation are simple, and while individuals considering the purchase of credits in forest schemes may be encouraged by efforts to improve accounting standards, it appears that caution and careful consideration remain important in choosing projects to support.
