How this solution relates to the action agenda

Axis: Unleashing Enablers and Accelerators including on Financing, Technology and Capacity-Building

Key Objective: 20. Climate and sustainable finance, mainstreaming climate in investments and insurance

Why it matters

With around 57 taxonomies worldwide (either under development or already in operation), interoperability is crucial to scaling up international climate finance. It helps reduce transaction costs, avoid duplicative verification, enhance market confidence, and prevent greenwashing. Greater alignment also provides clarity and certainty for investors, facilitating the channeling of global capital to where it is most needed, particularly in emerging markets, to support achievement of the Paris Agreement goals.
