Greenhouse Gas Accounting Efforts Undermined by Disparate Tools and Frameworks

The report highlights how disparate product-level GHG accounting tools and frameworks undermine climate mitigation efforts, especially in agriculture. It identifies key areas of variability—system boundaries, allocation methods, and data requirements—that lead to incomparable results and potential greenwashing. The author advocates for globally standardized methodologies, improved quality control, pre-competitive collaboration, and increased transparency to ensure that corporate Scope 3 emissions reductions are real and verifiable.

• Variability in product-level GHG accounting standards prevents companies from accurately understanding their true emissions and progress in reductions, a problem that is particularly acute in agriculture where "70% of emissions from cradle to grave occur on farms."
• The lack of standardization in product-level accounting allows for the potential manipulation of methodologies to facilitate greenwashing, as companies may "cherry pick calculations that offer a misleading picture of their emissions."
• Differences in allocation methods for multi-functional processes can lead to significant emissions being unaccounted for downstream; for example, over one-third of total emissions from aquaculture salmon are not passed downstream when actors use the allocation method that yields the lowest footprint.
• Agricultural GHG emissions are highly variable based on production practices; deforestation alone can multiply typical on-farm emissions tenfold, and emissions rates per product unit can vary 2-5 times even for farms in close proximity using similar practices.
• Existing GHG calculators do not solve the problem of variability, as results for the same operations can vary by over 2x due to methodological differences alone.
• The document identifies three critical reasons for harmonization: enabling comparison across suppliers or investments, setting credible emissions targets (such as those aligned with the Science Based Targets initiative), and facilitating knowledge sharing on effective mitigation actions.
