For over 50 years, UNEP has worked with governments, civil society, the private sector and UN entities to address humanity’s most pressing environmental challenges - from restoring the ozone layer to protecting the world's seas and promoting a green, inclusive economy.

UNEP is driving transformational change by drilling down on the root causes of the triple planetary crisis: the crisis of climate change, the crisis of nature, land and biodiversity loss, and the crisis of pollution and waste.

UNEP’s work is focused on helping countries transition to low-carbon and resource-efficient economies, strengthening environmental governance and law, safeguarding ecosystems, and providing evidence-based data to inform policy decisions.
