Established in 1970, NRDC (the Natural Resources Defense Council) works to safeguard the earth, its people, its plants and animals, and the natural systems on which all life depends. Our team of more than 800 lawyers, policy experts, scientists, economists, and communications specialists work across the United States and around the world, from offices in Washington D.C., New York City, Chicago, San Francisco, and Santa Monica, as well as a representative office in Beijing and affiliate offices in New Delhi (through NRDC’s wholly owned for-profit subsidiary, NRDC India Private Limited) and London (through its UK-based partner NRDC International).

At the Sierra Club, we believe in the power of togetherness. Together, we remain committed to the fight for a healthy climate built on a foundation of environmental, racial, economic, and gender justice – a future where all people benefit from a healthy, thriving planet and a direct connection to nature. As the climate crisis and deeply entrenched systemic racism all fuel inequity, we will continue to fight for a bold, transformational agenda that recognizes the interconnectedness between our planet, our humanity, and our democracy. By recognizing that our destinies are tied, we continue to name that all things are fundamentally connected, and the overlap between ecology, race, gender, and representative government will move to either advance our collective humanity or to oppress it. Sierra Club is comprised of staff across the country and a network of local chapters that support our grassroots engagement. We are also proud to be a unionized employer, with two labor unions representing more than half of our employees. Please view www.sierraclub.org/careers/ for more information.

As the founder of environmental reporting, we believe in transparency and the power of data to drive change. Partnering with leaders in enterprise, capital, policy and science, we surface the information needed to enable Earth-positive decisions. We supported more than 22,100 companies and over 1,000 cities, states and regionsdisclose their environmental impacts in 2025. Financial institutions with more than a quarter of the world’s institutional assets use CDP data to help inform investment and lending decisions. Our team is truly global, united by our shared desire to build a world where people, planet and profit are truly balanced. To meet the scale and speed of today’s environmental challenges and market expectations, CDP is becoming two separate organizations – a commercial entity, CDP, and a non-profit CDP Foundation. They will be united in shared ambition: to surface new information, enabling Earth-positive decisions to protect future generations. More information to follow.
