Relaxing rules on carbon markets would undermine climate action, scientists warn

Phys · · 535 words · By University

A group of scientists, including researchers from the University of East Anglia and the University of Zurich, argue against relaxing 'additionality' requirements in carbon markets. They suggest that while Indigenous stewardship should be supported, doing so through carbon credits could increase net emissions, and recommend alternative funding mechanisms instead.

“Responding to a recent comment article in the journal Nature Climate Change that calls for rethinking "additionality" requirements in carbon markets to better recognize Indigenous stewardship and conservation, a group of scientists emphasize that disregarding this principle could lead to higher net carbon emissions, ecosystem degradation and increased social inequality”
CORROBORATED
Multiple web search results confirm the existence of a response in Nature Climate Change arguing that relaxing additionality requirements would undermine climate action and potentially penalize Indigenous stewardship.

“The principle of additionality means that emission credits cannot be generated by activities that would have happened under a business-as-usual scenario, for example, the continued protection of existing carbon stores.”
CORROBORATED
Three independent web sources provide a consistent definition of 'additionality' as the requirement that emission reductions must be beyond a business-as-usual scenario.
