Center for International Environmental Law

The Center for International Environmental Law (CIEL) is a public nonprofit environmental law organization based in Washington, DC, with an office in Geneva, Switzerland. It was founded in 1989. CIEL's team aims to use "the power of law to protect the environment, promote human rights, and ensure a just and sustainable society. CIEL seeks a world where the law reflects the interconnection between humans and the environment, respects the limits of the planet, protects the dignity and equality of each person, and encourages all of earth’s inhabitants to live in balance with each other." They help educate organizations, corporations, and the public on environmental issues and conduct their own research. Rebecca Brown has been the President and CEO since 2025. CIEL also offer legal internship programs.
