A quick follow-up, Chris. Redd-Monitor itself cites the Oeko-Institut study, whose authors concede that 'it would be inherently challenging to develop a robust and representative study design that would be suitable to empirically test whether the use of carbon credits has a causal effect on internal emission reductions.' That's an admission of methodological limits, not a finding. It can't carry the weight of the claim being made.

Chris Lang’s piece repeats a familiar but incomplete critique of carbon markets. After having spent two decades in this space, I believe I have a perspective here. It is one thing to argue that carbon markets must be better governed; it is another to claim that decades of carbon trading have made no difference at all and that companies buying carbon credits do not decarbonize faster. That assertion does not reflect the evidence.

Trove Research, now part of MSCI, examined the emissions performance of more than 4,000 global companies and found that companies using material quantities of carbon credits were, on average, decarbonizing at twice the rate of companies that did not use them. MSCI’s later publication on the same topic found that carbon-credit users were more likely to disclose emissions, reduce Scope 1 and 2 emissions, reduce emissions intensity, set climate targets, and earn more revenue from low-carbon activities.

That matters because it directly contradicts the claim that carbon credits function as a “license to pollute.” The evidence cited by MSCI points in the opposite direction: voluntary carbon credit use has been associated with faster internal emissions reductions, not slower ones.

A more honest debate would acknowledge the real question: not whether carbon markets are perfect, but whether they can be structured with strong integrity, community rights, and transparent benefit-sharing so that they mobilize capital for climate action in the Global South. That is the case many of us are making. Indeed, that was the entire desire of us to help Liberia design a carbon market with first degree integrity.

Carbon markets are not a substitute for regulation, industrial decarbonization, or fossil-fuel phaseout. But dismissing them outright ignores the empirical evidence and overlooks their potential to channel finance from the Western world toward climate action and development in the Global South.

I would be more than happy to discuss directly with you if you want to discuss further. I am at spenrith@gordianknotstrategies.com
