About Giving Green

We make high-impact climate giving easier, for everyone.

What can I do about climate change?

We had the same question. So we created Giving Green.


Giving Green is a guide for individuals and businesses to make more effective climate giving decisions. We perform rigorous research and recommend highly effective climate initiatives, so you can give with confidence.

Giving Green is incubated at IDinsight, a global advisory, data analytics, and research organization that uses data and evidence to improve lives worldwide.​ We are also inspired by the principles of effective altruism, which seek to find ways of doing good that actually work. We bring IDinsight’s deep expertise and effective altruism’s research rigor to everything we do.

Our work is funded by generous climate donors like you who believe in high-impact climate action and evidence-based climate giving advice. We receive no funding from and have no formal relationship with any of the organizations we study or recommend. If you share our mission, please consider donating to Giving Green directly.

We also provide consulting services to individuals and organizations that want to give more effectively to fight climate change. Learn more about how we create bespoke climate giving recommendations here.



To guide our search for effective climate projects, we strive to uphold four values. These are our commitments to teammates, supporters, and the planet. 


1. Truth-seeking

We ask challenging questions and perform rigorous research, guided by evidence and reason. 

2. Humility

We value different perspectives and acknowledge our own limitations. 

3. Transparency

We share research and deliberations publicly to encourage dialogue. 

4. Collaboration

We foster catalytic partnerships to amplify climate actions and maximize impact.
