Water doesn't recognize borders — and neither do the threats it faces. Our international teams work year-round to defend it.

This work is possible because of community members like you. Your voice is essential.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across political boundaries to rebuild what was lost.

The water that flows through you connects you to 7 billion people — and billions more organisms. Protect it with us.

'Thirty years ago, this river was forgotten. Through their work, the ecosystem breathes again. I work alongside their team.' — Commissioner James

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We monitor trends so communities can act.
