What are the best climate change charities?

When choosing a climate nonprofit, the top two questions are what they do with your money and how effective they are spending it. But it’s very hard to tell the difference among hundreds of environmental nonprofits out there.

Thankfully, services like Charity Navigator and Charity Watch analyze hundreds of charities and score their effectiveness. Giving Green and Founders Pledge also provide recommendations, including less well-known and well-funded charities.

We’ve compiled a list of the top-rated climate organizations, ranging from nonprofits combating “the war on science” to charities fighting deforestation in the Amazon and keeping plastic out of the oceans.
