On the lookout for some of the best climate change charities and nonprofit global warming organizations working towards a better future for humanity? Then you are in the right place.

Maybe you think about donating to a climate cause as you watch wildfires burn in Australia and California, ice shelves shatter in the Arctic, and glaciers break loose in Antarctica, all at the same time. Climate change drove the news cycle for the past few years, from the Global climate strike, Greta Thunberg’s climate change speak, Green New Deal, to the U.S.’s transition to a clean energy economy.

From the environmental movement pillars to innovative, emerging charities, we’ve highlighted respected nonprofit organizations doing ongoing work to fight climate change. The ten best climate change charities below are just a few cost-effective and evidence-based nonprofit organizations working to clobber climate change. 

Which nonprofits should you support?


Climate change is the biggest challenge humanity will face. Yet, our global response has been outrageous, causing more climate problems. Over the past decade, our carbon dioxide has risen to 11%. We need to reverse that trend, and we need to do it fast. 

Contributing to a charitable foundation displays the best of human nature and pushes more action for climate change organizations.

But what exactly can charitable efforts on that scale do to slow the pace of global warming?

Climate change charities spend significant sums and efforts to increase public awareness of the problem and help people cope with its consequences. They do this simply because people have already lost their homes, livelihoods, or loved ones because of the changing climate. 


All of us want to do something for positive change, so we turn into organizations dedicated to defending the environment and advocating for a green economy. Most of these nonprofits have been investigated and reviewed by Charity Navigator. If you’re considering supporting a particular cause, try searching for it on Charity Navigator or other “watchdogs,” as they sometimes provide a unique perspective.

They stand behind their missions and have the clout to get big things done. They operate on a large-scale, whose work has a broad scope. Check out these ten best global warming charities and global warming organizations until you find what fits your priorities and what suits your cause.

Coral Reef Alliance

Coral reefs, or the “rainforest of the sea, “are some of the most biodiverse and productive ecosystems on earth. But coral reefs are endangered because of various factors such as hurricanes, El Nino, overfishing, destructive fishing techniques, coastal development, pollution, careless tourism, warming seas, and increasing levels of co2 in the water because of global warming.

Coral Reef Alliance is a nonprofit organization in San Francisco, California, whose mission is to bring awareness of coral reefs’ extermination worldwide.

The Pelorous Foundations also support the Coral Reef Alliance to search for real-world conservation solutions to improve the entire marine ecosystem. Coral Reef Alliance works collaboratively with communities to reduce direct threats in ways that provide lasting benefits to humanity and wildlife. They also actively expand scientific understanding of how coral adapts to climate change and apply these studies to give coral reefs the best chance to thrive for future generations.

Clean Water Fund

Only 3% of the world’s water is freshwater, and two-thirds of that is in frozen glaciers or otherwise unavailable for human use. As an outcome, approximately 1.1 billion people globally have no sufficient access to water, and 2.7 billion people don’t have access to water for at least 31 days of the year. These people are likely exposed to cholera, typhoid fever, and waterborne illnesses. Two million, most of whom are children, die yearly from diarrheal diseases alone.

Clean Water Fund’s sustainable programs reach and involve a million households each year through continuous learning, outreach, development, organizing, advocating, and legal action at the local, state, and national levels. With our support, the Clean Water Fund will bring clean water, sanitation, and hygiene to communities nationwide, ultimately cutting child deaths by more than just half.

Coalition for Rainforest Nations

Amazon is the largest deforestation front globally, and interventions are highly needed to prevent a massive-scale, irreversible environmental disaster. 17% of the forest has been lost in the last 50 years because of forest conversion for cattle ranching.

Coalition for Rainforest Nations is an intergovernmental organization of over 50 rainforest countries that promotes ecological sustainability while developing opportunities for sustainable innovations within tropical forested nations. They paved the road for establishing a global agreement on deforestation in U.N. climate change treaties.
