Systematic Observation Impact Bond
A pioneering finance instrument for weather and climate data
A global public good
Why closing the data gap matters
Nearly 90 per cent of the basic weather and climate data required from the 77 Least Developed Countries and Small Island Developing States is missing.
These countries — at the core of the SOFF mandate — operate barely one in ten of the stations mandated under the internationally agreed GBON standard.
The consequences are global – weakening resilience, threatening economies and putting lives at risk.
Innovating climate finance
The Systematic Observation Impact Bond – a pioneering climate finance instrument – will help close the critical weather and climate data gap in at least 30 Least Developed Countries and Small Island Developing States.
Designed to fast-track the mobilization of USD 200 million by end 2026, it will enable countries to act quickly through capital frontloaded by investors, supported by long-term donor commitments.
Contributions will be tied to independently verified results — five-fold increase in internationally shared weather and climate data. The bond is built on a broad coalition of governments, development agencies, philanthropies, and businesses.
