Crowdfunding to Fight Climate Change
Climate change is the issue of our time. Cool Effect makes it easy to support projects around the globe that use simple technologies that are scientifically proven to reduce earth-warming emissions. If we each take action to support these projects, they will grow. When they grow, they reduce more emissions. That is the Cool Effect.
Tonnes saved to date
The average American emits 17 tonnes of CO₂ a year. Each tonne saved by Cool Effect helps mitigate the impact to our planet. SEE HOW
Carbon Busting Projects
Proyecto Mirador Clean Cookstoves
More than 145,000 clean stoves built.
Alto Mayo Conservation Initiative
Tropical forests are the Earth’s lungs—absorbing CO₂ and releasing oxygen. This project seeks to protect nearly 450,000 acres from deforestation. More trees = more oxygen.
Southern Ute Indian Tribe Methane Capture
Each year, this project reduces up to 27,000 tonnes of greenhouse gas emissions. That’s the equivalent of 1,588 average Americans emitting no greenhouse gases (not even by breathing) for a whole year.
Los Santos Wind Power Project
When Mother Earth breaks wind, turbines generate renewable energy, supplying electricity to thousands of Costa Rican families. This reduces both CO₂ emissions and the country’s reliance on fossil fuels.
How We Select Projects
Our scientists scour the globe to find the world's best projects that are proven to verifiably reduce greenhouse gas emissions.
We verify the science behind the projects and examine their financial records and management to ensure that they meet our high standards.
We bring these great projects together in one place where our community comes together to help them grow. Over 90% of each contribution goes directly to the projects.
The California Cool Effect
Cool Effect hosted a public forum that united community members and thought leaders in policy, climate, non-profit, and sustainable storytelling to raise awareness, enlist support, and learn about ways to take environmental action.

How big is a tonne of CO2?
Today’s party stopper: a metric tonne of CO2 fills about 100,000 balloons. That’s no fun for the planet.
Hottest game on Earth: a metric tonne of CO2 fills the space expanding 10 yards on a football field.
There goes the neighborhood: a metric tonne of CO2 would fit in a cube the size of a two-story house.
