ICVCM Rejects Eight Renewable Energy Methodologies on Additionality Grounds

The Integrity Council for the Voluntary Carbon Market found that eight carbon crediting methodologies used for renewable energy projects fail to meet its additionality requirements, meaning credits from these projects cannot carry the CCP label. The council said carbon finance for renewable energy remains important but must be directed exclusively to projects that have no other means of obtaining investment.

The ICVCM's assessment identified three core deficiencies in the eight methodologies reviewed: difficulty in demonstrating additionality as renewable energy costs have fallen globally, insufficient conservativeness in grid emission factor calculations, and inadequate quantification of suppressed demand barriers. These weaknesses can lead to overstated emissions reductions claims. The council noted that while renewable energy costs have declined dramatically over the past decade, this decline has not been uniform across all countries, particularly least developed nations.

The ruling highlights a critical distinction: carbon finance for renewable energy is only justified where it enables projects that would not otherwise be viable. Misallocating carbon finance to projects with existing access to funding could undermine trust in the voluntary carbon market and reduce the incentive for governments and industry to independently scale up renewable energy capacity. The ICVCM pointed to the IPCC's view that renewable energy must scale rapidly by 2030 to meet global emissions targets.

The Integrity Council confirmed it will assess more rigorous renewable energy methodologies once they are developed, noting that Verra's VCS and Gold Standard programmes are already working on updated methodologies that better account for variable circumstances across different geographies. A new Continuous Improvement Work Programme is being established to explore how carbon crediting can support a just transition away from fossil fuels, including the social impacts on workers in affected industries. The ICVCM expressed hope that new methodologies will unlock finance for renewable energy in regions where it is most needed.
