Donate to Environmental Defense Fund, which advances climate solutions and works to protect communities from pollution and toxic chemicals. Much of its work involves scientific research and legal advocacy aimed at changing environmental policy and corporate practice.
A broader policy-and-science approach to climate work than the hands-on planting or land-buying options nearby — a fit if you want your gift to support systemic solutions rather than one physical project. Combining scientific research with legal advocacy also means it works to change the rules companies and governments operate under, not just fund individual projects within those rules.
