How can I fight climate change?

Scientific. Transparent. Actionable.

Giving Green is an evidence-based guide that helps donors and volunteers fight climate change.

Scientific Icon


Many nonprofits, corporations, and communities are working to reduce greenhouse gases in the atmosphere, but only some of these efforts are based on the best available scientific evidence. Giving Green identifies effective projects, backed by solid physical and social science.

Actionable Icon


We know the world is warming, but understanding how we can fight climate change with our own time and money is difficult in the face of an all-encompassing crisis. Giving Green makes effective climate action just a click away.

Transparent Icon


As the urgency of the climate crisis intensifies, resources need to be focused on the most effective solutions – and donors and volunteers need clear, objective facts about what works and what doesn’t. Giving Green publicly posts all of our research and encourages dialogue about what works.

Giving Green's Mission

Where to Donate

Climate change is complex. Giving doesn't need to be. Giving Green has poured hundreds of hours into these expert-researched reports so you don't have to. Every dollar matters, which is why we want you to feel confident knowing that if you give according to our recommendations, your climate donations will have real impact.

Us Policy Change

US Policy Change (Recommended)

Initiatives to influence US federal policy are bigger, riskier bets with the hope of changing the long-term arc of climate change. We believe policy change offers the best impact per dollar.

Carbon Offsets

Carbon offsets fund projects seeking to cause immediate, verifiable reductions of greenhouse gases. Many carbon offsets make big claims - we find those that follow through.

"It can be genuinely hard to figure out how to direct your money wisely if you want to reduce greenhouse gas emissions. There's a glut of environmental organizations out there and a lack of rigorous research on their impacts and cost-effectiveness, though that'll hopefully change soon with the arrival of brand-new evaluators like Giving Green."


"When we discussed how to make your climate change donations count, our reporting suggested that one of the most effective strategies is donating to political campaigns. But what if you’re not into politics and would rather help out a nonprofit organization instead? Unless you’re a scientist or policy wonk, figuring out who’s actually making a difference can feel like an impossible task."
