Climate drawdown is the point at which greenhouse gas concentrations in the atmosphere level off and begin to decline on a year-to-year basis. Drawdown is a milestone in reversing climate change, and eventually reducing global average temperatures.
Project Drawdown is a climate change mitigation project initiated by Paul Hawken and climate activist Amanda Joy Ravenhill. Central to the project is the compilation of a list of the "most substantive solutions to global warming". The list, encompassing only technologically viable, existing solutions, was compiled by a team of more than 200 scholars, scientists, policymakers, business leaders, and activists. The team measured and modeled each solution's carbon impact through the year 2050, its total and net cost to society, and its total lifetime savings.
Top ten solutions
|Solution||Min. CO2 -eq (Gt)
|Max. CO2 -eq (Gt) |
|Reduce food waste||87.45||94.56|
|Health and education||85.42||85.42|
|Tropical forest reforestation||54.45||85.14|
|Onshore wind turbines||47.2||147.7|
|Utility-scale solar photovoltaics||42.32||119.13|
|Improved clean cookstoves||31.34||72.65|
|Distributed solar photovoltaics||27.98||68.64|
Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming is a 2017 book created, written, and edited by Paul Hawken about climate change mitigation. Other writers include Katharine Wilkinson, and the foreword was written by Tom Steyer.
The book describes solutions arranged in order by broad categories: energy, food, women and girls, buildings and cities, land use, transport, materials, and "coming attractions". The book provides a list of 100 potential solutions and ranks them by the potential amount of greenhouse gases each could cut, with cost estimates and short descriptions.The Guardian notes that the author has had influence in corporate sustainability efforts and that companies such as Interface and Autodesk have backed the project. It was intended that the book be supplemented with an online database, Project Drawdown, which was to compile the numerous types of solutions.
A 2020 review of the findings of the research that lead to the 2017 book, was published as a 104 page pdf in 2020.
