For 20 years, CIEL has understood the interconnectedness
of our planet’s social and ecological systems, and sees collaboration, legal action, and public interest advocacy as essential means to protect those systems.



CIEL works to design and
strengthen international
environmental and health law,
including the conservation of
biological diversity, mitigation
of climate change, protection
of endangered species, and the
