Joint Statement: Why carbon offsetting undermines climate targets

Joint Statement

Why carbon offsetting undermines climate targets

In the past few months, we have seen a growing push, notably with the public statement of the SBTi Board of Trustees, to allow companies and countries to use carbon credits to offset their emissions. This reflects a bigger trend of bending carbon accounting rules, undermining actual emissions reductions.

Climate targets must focus primarily on reduction of greenhouse gas emissions within companies’ and countries’ own boundaries, including the phasing out of fossil fuel production, transport, sale and use. An urgent scale-up of financial support from both public and private actors is needed for this. But allowing companies and countries to meet climate commitments with carbon credits is likely to slow down global emission reductions while failing to provide anything like the scale of funds needed in the Global South, and reducing pressure to develop large-scale mechanisms such as “polluter pays” fees on emission-intensive sectors.

The reasons we are concerned by the renewed efforts to promote carbon offsetting include the following:

1. Offsetting could delay climate action

First, it is essential to understand that offsetting, at best, does not reduce the concentration of GHGs in the atmosphere, it simply moves emission reductions from one place to another. The logic of offsetting is built on the idea that one entity gets to keep emitting. For this reason, offsetting often ends up providing the social license for high-emitting activities to continue while reinforcing past injustices. For instance, fossil fuel companies have claimed to be reducing emissions by investing in planting trees while increasing their production of coal, oil and gas.

Peer-reviewed studies and reports6 show that corporate net-zero strategies regularly rely on carbon credits to meet emission reduction targets. In other words, if the use of carbon offset credits is allowed to meet emission reduction targets, there is a strong risk that the mitigation hierarchy is not followed, regardless of rhetorical pleas to prioritize reductions.

2. Carbon offsetting inherently lacks credibility

Scientific literature on the topic has shown significant quality issues with carbon crediting

programmes including:

• the likelihood that the majority of the billions of credits created up to now are not additional, i.e. that any reduction in emissions would likely have happened regardless of the carbon market (thus undermining the entire rationale for carbon crediting);

• the difficulty to set meaningful baselines, and the temptation to set unrealistic baselines and generate more carbon credits;

• the potential leakage or rebound effects, e.g. by merely shifting deforestation away from a project area to nearby areas;

non-permanent carbon removal which is falsely equated with the reduction of (permanent) emissions from the combustion of fossil fuels;

• and social and environmental harms uncovered by numerous investigations over decades showing that projects have e.g. been imposed without local consent or violated the land rights of Indigenous Peoples and local communities.

A common factor across these issues is that carbon crediting programmes are dealing with unknowables and have to guess the key parameters of their projects. There is a strong incentive to choose parameters that simply generate the most credits, which history shows tends to overwhelm any incentive for market participants and standard setters to fix these quality issues.

3. There are only so many “quality” credits that could be used as offsets

Even if all the quality issues mentioned could be fixed (which we do not believe is possible for a large volume of the market based on the inherent flaws of the concept cited above as well as the evidence of more than two decades of efforts to fix them), projects and land would not be sufficiently available to feed the demand for a pay-to-keep-emitting model, promoted by the inclusion of carbon offset credits into scope 3 emissions accounting.

4. The climate funding gap will not be solved by offsetting

Carbon credits send a misleading signal about the efforts required to pursue climate action, and they undermine carbon prices by providing a false sense of the existence of ultra-cheap abatement options around the world (a few dollars per ton of CO2e avoided/removed while estimates of the social cost of carbon usually place this cost in the hundreds of dollars per ton of CO2e). They also risk disincentivizing the significant investments needed to ensure profound changes to corporate value chains and economic systems.

Companies can make a positive impact by funding carbon-related projects beyond their own value chain. Such financial contributions can be a way for companies to acknowledge their broader and historic responsibility on climate change, but they neither reduce the necessary investments to abate emissions from their own operations, nor do they absolve them from accountability to clean up and pay for the impacts of their pollution.

Over 70% of the global historical GHG emissions can be attributed to 78 companies (private or state owned). Companies therefore have a responsibility to deeply and immediately reduce their own footprint by taking concrete measures to address the emissions in their global value chains, rather than simply buying credits to avoid tackling their own emissions problems. The difficulty to achieve these massive emission reductions cannot justify widely opening the door to creative accounting and climate distractions.

Currently, the most prominent voluntary and regulatory frameworks on climate transition planning and reporting exclude the use of carbon credits in meeting corporations’ interim emission reduction targets. In particular, the European Sustainability Reporting Standards (ESRS) state that carbon offsets cannot be merged with actual emissions reductions in corporate climate target reporting. The SBTi Standard Operating Procedure (SOP) commits to not go below national applicable law, hence SBTi must align with the ESRS. The recommendations from the UN HLEG15 also underline that carbon credits ‘cannot be counted toward a non-state actor’s interim emissions reductions required by its net zero pathway’. It is crucial to ensure consistency between these frameworks and keep ambition high to avoid a race to the bottom.

In a context in which our global carbon budget is rapidly decreasing, ensuring that focus will remain on actual reductions is paramount. It is worth noting the “technology-neutral” IPCC in its last Synthesis Report (2023) did not support or even mention offsetting as a viable option.

We call for scientific, ambitious, equitable, robust, credible and transparent rules around carbon accounting and corporate climate target setting. Voluntary and regulatory frameworks on climate transition planning must exclude offsetting.
