About Venture

In response to climate change, foundations, individuals, governments, and businesses are spending billions of dollars to tackle the crisis. But where should they put those resources? What are the most cost-effective, data-backed projects that are having a real impact in the climate fight?

There is an exciting plethora of climate initiatives that aim to reduce greenhouse gas emissions, but only some are based on the best available evidence. Supporting these highly effective initiatives is one of the most impactful climate action individuals and businesses can take. And we created Giving Green to help you find the organizations behind them


We are a team of climate scientists, economists and impact evaluation experts with decades of experience working at the intersection of evidence-based policy and the environment. We spend thousands of hours reviewing the studies, crunching the numbers and interviewing the experts, so you don’t have to.

We evaluate climate initiatives across different geographies, sectors, and approaches—from national charities to carbon removal projects to impact investment mechanisms—using rigorous impact evaluation methods. We then make expert recommendations that are scientific, actionable, and transparent.

We publish all of our research and deliberations, so you can be confident that our recommendations are scientific, transparent and actionable.
