UN carbon market expands to renewable power sector

The Article 6.4 Supervisory Body has adopted a methodology allowing eligible grid-connected renewable electricity projects to generate credits under the Paris Agreement Crediting Mechanism. Effective from 30 July 2026, A6.4-AMM-003 covers new hydropower, wind, solar and geothermal plants, subject to technology-specific restrictions and rigorous additionality tests. Projects must pass regulatory, lock-in, investment and common-practice analyses, meaning commercially viable or legally required renewable projects will not automatically qualify. The methodology excludes biomass, existing-plant retrofits and direct electricity supply to specified consumers. Solar projects cannot occupy officially classified agricultural or forest land, while eligible hydropower is generally limited to 15 MW and cannot involve new reservoirs. The Supervisory Body also updated the mechanism registry procedure but postponed approval of a household cooking efficiency methodology pending further work. The decision expands the mechanism beyond previously approved landfill-gas methane and nitric-acid nitrous-oxide methodologies while maintaining conservative safeguards.
