Shared principles for growing high-integrity use of carbon credits by companies and other buyers
This guidance by the Coalition to Grow Carbon Markets outlines voluntary principles for increasing high-integrity corporate demand for carbon credits. It sets expectations for decarbonisation-first strategies, procurement of high-quality reductions and removals, fair pricing, co-benefits, transparent disclosure and substantiated claims. The principles draw on PACM, ICVCM and CORSIA standards, and encourage government alignment to improve market consistency, legal clarity and recognition of credible buyers.

VCMI’s Scope Action Code of Practice
This guidance from VCMI helps companies navigate Scope 3 emissions in line with credible climate action. It outlines three key principles: reduce first, disclose transparently, and limit credit use to no more than 25% of Scope 3 emissions annually. The Code complements SBTi targets and integrity claims, ensuring that corporate offsetting strategies do not undermine decarbonization. It aims to create demand-side accountability, clarify buyer claims, and bolster trust in high-quality carbon markets as part of the net zero transition.

It identifies market levers (e.g. Scope 3 frameworks, policy alignment, pricing clarity) that could influence uptake. The model helps guide strategy for developers, buyers, and intermediaries navigating future carbon market dynamics.
