The early CDM methodologies targeted both fuel switch to renewable energy (AMS I.E) and energy efficiency improvement (AMS II.G) and developed associated tools such as for showing additionality and specifying default parameters. Their implementation has been instrumental in building the sector including through their adaptation into methodologies developed by the voluntary standards agencies. This has seen a wider application of innovative methodologies that can cater to large-scale and broader sectoral frameworks (RECH: TPDDTEC) and for micro-scale projects covering generation of even less than 10,000 credits per year.
The VCS methodology VMR0006 is adapted from the CDM AMS II.G and was revised to version 1.2 on 6 July 2023; this incorporates both fuel switch and efficiency improvement. VCS is also developing a modular methodology called Improved Thermal Energy Generation Units, which covers a broad set of activities and consolidates elements of existing methodologies: VMR0006, AMS II.G, and AMS I.E. Similarly, GS together with CCA as part of the Clean Cooking & Climate Consortium (4C) is developing a modular methodology for crediting emissions reductions from cooking projects. CDM methodologies can be applied to the GS and VCS standards, however, the reverse is not applicable.
GS has a suite of methodologies, including the long-standing TPDDTEC updated in October 2021. GS has also now introduced a new methodology called the Metered and Measured Energy Cooking Devices (MMECD), which is specifically designed for higher-tier and modern energy cooking services: specifically electric cooking stoves including pressure cookers, as well as LPG, biogas, and bio-ethanol stoves. The particular feature of the MMECD is that it applies to projects that can measure cooking energy use in real-time or periodically e.g., with electric stoves with in-built metering. This follows the ongoing evolution of digital carbon and impact platforms, reducing project costs and also improving accuracy of emission reduction measurement- hence improving the integrity of the credits.
This Summary of Carbon Financing methodologies for Clean Cooking provides a comparison of different methodologies including links to the detailed methodologies and required tools such as for proving additionality. The synthesised information relates to scope, applicability, additionality, baseline and project fuel consumption, quantifications of baseline, project and leakage emissions, and principal monitoring requirements. There are six frequently used methodologies, and only the recent MMECD is specifically designed for the higher tier cooking services.
Information on the tests proposed and required by the methodologies for project validation and verification can be found here.
