Should your country prioritize increased public spending to address global biodiversity loss?
Global biodiversity finance totaled between USD 74.9 billion and USD 92.4 billion annually from 2023 to 2025. This OECD-backed analysis provides a retrospective look at funding growth across public and private sectors.
Why it matters
The report benchmarks the current scale of financial mobilization required to address ongoing biodiversity loss. Understanding these funding trends is essential for tracking progress against global environmental targets.
International public finance rose by 94% and private investment grew by 73% compared to the 2018-2020 baseline period. Public domestic expenditure, the largest contributor, increased by 16% over the same duration.

The details
The analysis utilized consistent time-series data from 63 countries to track fiscal inputs. It categorized spending into public domestic expenditure, international public finance, and private domestic and international investment. This systematic tracking allows for a comparative look at how different funding streams have evolved against 2018-2020 benchmarks.

The Tech Race
This data sits as a foundational metric for the upcoming COP17 meeting in Yerevan, Armenia. The figures will serve as the primary evidence base for evaluating the efficacy of current financial mobilization strategies against international conservation goals.
The report details how global capital flows are shifting toward conservation, which influences the availability of funding for regional environmental projects. While these figures represent high-level fiscal trends, they signal a broader prioritization of nature-based investments that may eventually affect local environmental policy and resource allocation.
The takeaway
The data confirms a significant scaling of international and private biodiversity funding compared to recent years. Observers should track the outcomes of the COP17 meeting in 2026 to see if these trends translate into new, formalized commitments for nature protection.
What happens next
The COP17 meeting is scheduled to take place in Yerevan, Armenia, from October 19-30, 2026.
