Drawdown is that point in time when the concentration of greenhouse gases in the atmosphere begins to decline on a year-to-year basis.
Project Drawdown is based on meticulous research that maps, measures, models, and describes the most substantive solutions to global warming that already exist. It is the most important goal for humanity to undertake.
Project Drawdown is the most comprehensive plan ever proposed to reverse global warming. It involves a coalition of researchers, scientists, policy makers, business leaders and activists, who have assembled and presented the best available information on climate solutions deployed at scale. Solutions are described and quantified for their financial, social and environmental impact over the next thirty years.
Over 100 solutions were assessed. The top 15 are listed below from the project’s Plausible Scenario, which models the solutions based on a reasonable, but vigorous growth rate from 2020-2050. The list below also shows the total reduction from each solution in atmospheric carbon dioxide (equivalent) in Gigatons (US).

Carbon pricing is not included in the listing as it is a mechanism to implement solutions and not in itself a solution to global warming. Project Drawdown only focuses on technological, ecological, and behavioral solutions. The team chose not to model incentive-based policies and financial mechanisms, such as carbon pricing or congestion pricing, although these may be the keys to the more widespread adoption of many solutions.
