Climate Bonds’ Equivalence Methodology - Climate Mitigation

The Climate Bonds Initiative (CBI) has developed an Equivalence Methodology for Climate Mitigation to operationalise interoperability between various global green finance taxonomies. The methodology provides a technical framework to assess whether externally developed criteria for economic activities and decarbonisation measures are equivalent to CBI's science-based standards, allowing them to be incorporated into the expanded Climate Bonds Taxonomy and Certification Scheme.

• Climate Bonds developed the Equivalence Methodology to address market fragmentation and greenwashing risks caused by the proliferation of over 65 national and regional taxonomies with diverse technical screening criteria.
• The methodology defines 'equivalence' as a granular, technical sub-layer of interoperability that determines if specific taxonomy elements can be treated as interchangeable for practical use cases, provided they contribute to the Paris Agreement's climate mitigation goals.
• Externally developed criteria can be deemed equivalent if they substantially align with existing Climate Bonds Sector Criteria, such as having a variance of no more than 5-10% from a Climate Bonds emissions intensity pathway.
• Activity-level criteria must satisfy seven principles to be considered equivalent, including consistency with ambitious temperature goals (1.5°C for developed markets and 'well below 2°C' for emerging markets) and a requirement that metrics be physical or product-based rather than revenue-based.
• Measures-level criteria are assessed against three principles: they must represent a significant leap in decarbonisation (e.g., 20-40% emissions reduction relative to baseline) or be a 'no regret' measure, and they must not lock in fossil fuels or lock out electrification.
• The methodology includes five governance principles for the development of external criteria, requiring that they be developed by parties without conflicts of interest, use publicly available methodologies, and undergo multi-stakeholder public consultation.
• Criteria are adopted for either global or local use; those based on global integrated climate models are applied regardless of location, while those incorporating local factors or data are restricted to the jurisdiction specified by the developers.
