Methodology
AMS-II.G.
Also known as: Energy efficiency measures in thermal applications of non-renewable biomass
TL;DR
CDM small-scale methodology for energy-efficiency measures in non-renewable biomass thermal applications — the standard methodology for clean-cookstove projects.
Full explainer
AMS-II.G. is the CDM small-scale methodology under which the bulk of clean-cookstove carbon projects are registered. It credits the displacement of non-renewable biomass (typically firewood, charcoal) by more-efficient cookstoves, with the reduction calculated from (i) the baseline thermal demand, (ii) the share of demand met by non-renewable biomass, and (iii) the efficiency improvement of the project stove.
A few Indonesian clean-cookstove projects use AMS-II.G., particularly in rural areas of Eastern Indonesia (NTT, NTB, Maluku) where biomass dependence remains high. The methodology has been controversial in recent years — usage-monitoring assumptions have been challenged for over-stating reductions, and ICVCM has not granted CCP eligibility to the cookstove category broadly. Verra's analogue (VMR0006) faced similar critique. Projects are migrating to stricter usage-monitoring protocols.
