About The Climate Pledge

The Climate Pledge is a call to businesses and organizations to take collective action on the world’s greatest crisis and to work together to build towards a safe and healthy planet for the next generations.

How it all started

In 2019, Amazon and Global Optimism co-founded The Climate Pledge, a commitment to net-zero carbon by 2040. Since then, a growing list of major companies and organizations have joined The Climate Pledge. These signatories play a critical role in stimulating investment in the development of low-carbon products and services.

The Climate Pledge is a cross-sector community of companies and organizations, working together to crack the climate crisis and solve the challenges of decarbonizing our economy.

Bringing together those that are prepared to run the furthest and fastest, The Climate Pledge calls on signatories to reach net-zero carbon emissions by 2040—10 years ahead of the Paris Agreement. Amazon co-founded the Climate Pledge with Global Optimism in 2019, and became the first signatory of the pledge.

The Pledge Commitments

Signatories that sign The Climate Pledge commit to the following three principles:

Regular Reporting

Measure and report greenhouse gas emissions on a regular basis.

Carbon Elimination

Implement decarbonization strategies in line with the Paris Agreement through business change and innovations, including efficiency improvements, renewable energy, materials reductions, and other carbon emission elimination strategies.

Credible Offsets

Take action to neutralize any remaining emissions with additional, quantifiable, real, permanent, and socially beneficial offsets to achieve net-zero annual carbon emissions by 2040.
