Drawdown is the future point in time when levels of greenhouse gases in the atmosphere stop climbing and start to steadily decline.

Project Drawdown

Drawdown is a critical turning point for life on Earth. It is when we begin the process of stopping further climate change and global warming.

The good news is that we have what we need to bend the curve before 2050, from ancient human practices to recent technological innovations. And in the process, we can realize enormous social and economic co-benefits.

This becomes the foundations for a philosophical framework — a positive approach to the climate crisis based on action, solutions and opportunity.

Project Drawdown

The idea of Drawdown started with environmentalist and author Paul Hawken’s observation that there was no directory or comprehensive resource of solutions to global warming. Since its inception in 2014, Project Drawdown has become the world’s leading resource for climate solutions. Hundreds of scientists and experts have worked on a database of the most substantial methods of reducing emissions, based rigourous scientific calculations and the best available data. The first results were published in a bestselling book in 2017 and an update was released in 2020.

The genesis for Project Drawdown was curiosity, not fear. In 2001 I began asking experts in climate and environmental fields a question: Do we know what we need to do in order to arrest and reverse global warming?
