Climate Bonds’ Equivalence Methodology - Climate Mitigation

The Climate Bonds Initiative has developed an Equivalence Methodology to reduce market fragmentation caused by the proliferation of over 65 national and regional sustainable finance taxonomies. The methodology provides a technical framework to determine if externally developed activity-level and measures-level criteria are 'equivalent' to Climate Bonds' science-based standards. Criteria deemed equivalent will be integrated into the Climate Bonds Taxonomy and its Standard & Certification Scheme, creating a single reference point for global capital flows. The process involves screening for alignment with temperature goals, scientific robustness, and governance transparency, with a specific distinction between criteria applicable globally versus those limited to a specific local jurisdiction.

• The proliferation of over 65 national and regional taxonomies has led to market fragmentation and increased transaction costs, complicating investor assessments and increasing greenwashing risks, particularly in hard-to-abate sectors.
• Climate Bonds defines 'equivalence' as a granular, technical sub-layer of interoperability that determines if specific taxonomy elements can be treated as interchangeable for practical market use cases.
• Externally developed activity-level criteria are considered equivalent if they meet seven principles: alignment with ambitious temperature goals (1.5°C for developed markets; 'well below 2°C' for emerging markets), scientific basis, sector specificity, comprehensive emissions coverage (at least 80% of scope 1, 2, and 3), coverage over time to net-zero, no reliance on offsets, and the use of physical or product-based metrics rather than revenue-based units.
• Measures-level criteria are deemed equivalent if they represent a significant decarbonisation leap (such as replacing high-carbon systems or achieving 20-40% emissions reductions), do not lock in fossil fuels, and do not lock out electrification alternatives.
• To be recognised, externally developed criteria must adhere to five governance principles, including the use of a publicly available methodology, development by parties without conflicts of interest, and multi-stakeholder public consultation.
