The need for convening inclusive dialogues
In a previous blog, we highlighted the extent to which the UK carbon removal sector needed to develop and scale by orders of magnitude.
This process of carbon removal - also known as negative emissions - is an essential part of achieving net zero and eventually net negative emissions, both to offset the most persistent remaining emissions and eventually to bring back down the concentration of CO2 in the air to more sustainable levels.
A recent report Delivering the 'Net' in 'Net Zero'  by the Coalition for Negative Emissions highlighted the positive steps that are being taken by the UK actors to establish and realise a negative emissions sector along the lines of 3 pillars - as follows (p17 of report):
- Voluntary market - a growing number of companies and investors are looking to buy carbon removal credits to meet their own Net Zero targets, many of which are as early as 2030.
- Government-supported market - grant funding or long-term concessions will underpin early negative emissions investment where the negative emissions price alone is not high enough to underpin investment; and
- Regulated/compliance market - as negative emissions become accepted in regulation as an additional method through which companies can meet their emission reductions targets faster or compensate for emissions that are impossible to remove.
The report paints a very positivist perspective as to the relationship between the three `pillars’ in how they are mutually reinforcing and `virtuous’. It anticipates that the voluntary sector, which will potentially develop to a $30 to 50B market by 2030, will develop standards that can be incorporated into the regulated sector. The UK government-supported projects will create a supply of negative emissions for investors - up to 5 million tonnes of carbon dioxide per year from the atmosphere by 2030. It aims to grow this amount to 23 million tonnes by 2035. This will perpetuate scale to reduce costs and therefore private sector risk, reducing the dependency on a government-supported market.
At the Carbon Removal Centre, we have been closely engaged with entrepreneurs and activists in the space who have led us to consider the following counter-narratives.
Firstly, the fact that for corporates interest in CDR is not purely a climate play . While climate and sustainability objectives have increasing weight in corporate decision-making, these sit within the broader fiduciary duty of corporate directors to ensure a company's success - especially in providing returns to shareholders. This, therefore, incentivises the motivation to realise climate targets as cheaply as possible.
Secondly, the willingness of corporates to engage in the voluntary sector is based on the balance of risk of not doing so. Should corporates lose confidence in engaging in the sector as a function of civil society advocacy causing brand or reputational damage then the broader willingness of the private sector and as demonstrated in the past for governments to support the sector can also rapidly evaporate .
Impact on the carbon market
So how do these tensions sit in the nascent negative emissions offset market? Early signs are that the quality of negative emissions offsets in the voluntary sector are highly variable - as per the following observations from two early movers - namely Microsoft and Stripe :
- Microsoft received 189 proposals offering 154 MtCO2 - only 55 MtCO2 were available immediately, and a mere 2 MtCO2 met Microsoft’s criteria for high-quality CO2 removal. They…..chose to purchase from 15 suppliers representing more than 1.3 million metric tons of carbon removal (MtCO2) - see figure opposite.
- Stripe’s 47 carbon-removal proposals amounted to 16 MtCO2, but only 0.024 MtCO2 met the company’s requirement that carbon remain sequestered for at least 1,000 years - see figure opposite.
- On average, in the pitches that Stripe received, biosphere-based storage projects cost only $16 per tonne of CO2 (tCO2), whereas geosphere-based storage costs, on average, $141 per tCO2 ($20–10,000 per tCO2)
Both Microsoft and Stripe have very strict standards - basing their choices on specific criteria including clarity of carbon accounting, additionality, durability, potential leakage, and other environmental and social considerations. These are unlikely to be the norm for all actors operating in the voluntary market. With such a range of quality and standards - in a market which the private sector is both stimulating supply and calling on demand - all of whom are seeking a return for profit and/or return of value to shareholders. In the absence of oversight and transparent compliance mechanisms - where the credibility of offsets is called into question - will likely result in one of two outcomes.
One where the credibility of the voluntary sector is called out before the establishment of the regulated sector and the other where the credibility of the voluntary sector is called out as a function of the development of the regulated sector. In either case a complete collapse in credibility of the voluntary market with regards to price, legacy offsets and the credible realisation of net zero targets might be a very real outcome. In the case of the former the additional impact will be that the negative emissions off-set market might collapse before it is even regulated and scaled. This could lead to a long delay in government commitments, certainly from funded projects to regulated market i.e. from grants to ETS compliance or similar.
The extent of risks, therefore, loops back to and reinforces the concluding section of the previous blog:
We need to recognise that, unlike the renewable energy transition, substantive and multi-billion corporate engagement in this space is running far ahead of coordinated government action. This means corporate engagement and voluntary standards are setting the shape and tone of the CDR debate. More will be learned by doing than can be worked out in the policy process. This will have negative effects as well as positive ones.
What does this mean?
This means there is an urgent need to build an independent and impartial convening safe space which is inclusive which can build trust and knowledge for all actors who are seeking to engage in the negative emissions sector as the sector transitions from a voluntary based to a regulated sector. Based on our research there is a need to:
- Guide and bring together companies and civil society groups to address knowledge gaps around large-scale carbon removal, to inform better governance and practice;
- Establish how to deliver high integrity solutions in a way that deals with uncertainty, manages risk, and supports just, equitable and sustainable climate action; and
- Assist organisations explore the landscape, to envision their unique role within it, and to engage with other key participants for better results.
In short, the UK needs to build a high integrity carbon removal sector from the bottom up - in a way in which all voices are heard, and the results benefit everyone.
This won’t be easy: reality is messy, and the task is daunting. But bringing different actors together around shared societal goals is a crucial first step.
