Here are some key takeaways

  • In No pain, no grain (2024), we highlighted the credibility challenges of rice methane projects, including one project rated D on our platform.

  • Our most recent ratings show improvement: CAR1513 (USA) achieved an ‘A’, while The Good Rice Alliance (India) received an ‘A.pre’ ex ante rating.

  • These projects benefit from updated methodologies, improved monitoring, reporting, and verification (MRV) approaches, and stronger additionality cases.

  • While these ratings suggest that higher-quality rice methane projects are possible, the extent to which this holds more broadly is still to be determined.
