If you’re concerned at all about the fate of our planet – and you should be – it’s natural to wonder what you can do to help beyond reducing, reusing, recycling and composting your own banana peels. You can always volunteer locally, but if you’d rather help by donating money instead of time, you face a dilemma. By some estimates, the United States is home to nearly 15,000 registered  environmental organizations and nonprofits you can support, focused on everything from renewable energy or animal welfare. How do you sort through them all to make sure your money is going to the ones making the biggest impact?

All environmental organizations and nonprofits work in some way to protect the Earth, or part of it, from the damaging effects of human civilization. But that’s about all they have in common. The range in their individual scopes and missions is immense, so you have to decide what aspect of the environment is most important to you. Do you want to save whales, or protect the rainforest? Does renewable energy charge you up, or do you dig organic agriculture?

Then, do your research. Look into prospective nonprofits to see how credible they are, where they operate, and how effective their programs are. And make sure they’re a registered nonprofit, so you can write your donation off on your taxes. To help you choose, we’ve created a list of environmental organizations and nonprofits you can support. All of these received high scores from Charity Watch and Charity Navigator based on their impact, the total expenses they spent on their programs, the amount it costs them to raise $100 in donations, and other financial measurables.
