Drawdown maps, measures, models, and describes the 100 most substantive solutions to global warming. For each solution, we describe its history, the carbon impact it provides, the relative cost and savings, the path to adoption, and how it works. The goal of the research that informs Drawdown is to determine if we can reverse the buildup of atmospheric carbon within thirty years. All solutions modeled are already in place, well understood, analyzed based on peer-reviewed science, and are expanding around the world.
The subtitle of Drawdown—The Most Comprehensive Plan Ever Proposed to Reverse Global Warming—may sound brash. We chose that description because no detailed plan to reverse warming has been proposed. There have been agreements and proposals on how to slow, cap, and arrest emissions, and there are international commitments to prevent global temperature increases from exceeding two degrees centigrade over pre-industrial levels. One hundred and ninety-five nations have made extraordinary progress in coming together to acknowledge that we have a momentous civilizational crisis on our earthly doorstep and have created national plans of action. The UN’s Intergovernmental Panel on Climate Change (IPCC) has accomplished the most significant scientific study in the history of humankind, and continues to refine the science, expand the research, and extend our grasp of one of the most complex systems imaginable—climate. However, there is as yet no roadmap that goes beyond slowing or stopping emissions.
To be clear, our organization did not create or devise a plan. We do not have that capability or self-appointed mandate. In conducting our research, we found a plan, a blueprint that already exists in the world in the form of humanity’s collective wisdom, made manifest in applied, hands-on practices and technologies. Individuals, communities, farmers, cities, companies, and governments have shown that they care about this planet, its people, and its places. Engaged citizens world over are doing something extraordinary. This is their story.
