ACM0002

Full explainer

ACM0002 is the CDM Approved Consolidated Methodology for grid-connected electricity generation from renewable sources. It covers utility-scale hydro, wind, solar PV and CSP, geothermal, and tidal generators that feed an interconnected grid, calculating reductions against a combined-margin grid emission factor.

It is the most-used large-scale CDM methodology in history and underpinned a substantial share of pre-2020 CER issuance from Indonesian, Indian, and Chinese renewable plants. With CDM transitioning to the Article 6.4 Paris Agreement Crediting Mechanism, many ACM0002 projects have either reached the end of their crediting periods or have transitioned to voluntary registries; new large hydro and grid-renewable issuance under the original CDM has effectively wound down.
