Methodology for Assessing Emission Reductions from Rice Cultivation

This methodology enables the quantification of reductions in multiple climate forcers, including methane (CH₄), nitrous oxide (N₂O), and black carbon (BC) that result from sustainable rice cultivation practices such as water management, reduced nitrogen application, and avoided biomass burning thereby enabling a more comprehensive radiative forcing-based climate impact assessment.  

This methodology is based on the Clean Development Mechanism (CDM) methodology AMS.III-AU Small Scale Methodology: Methane emission reduction by adjusted water management practice in rice cultivation Version 04.0, Gold standard-GS437 and Verra-VCS0051 and the Climate Action Reserve’s U.S. Rice Cultivation Project Protocol Version 1.1, and references to the application of the Denitrification-Decomposition (DNDC) biogeochemical process model therein. This GHR Methodology follows the IPCC (2019) Guidelines for Greenhouse Gas Inventories, and the DNDC model ensuring methodological consistency with international standards.
