To uncover that answer, we review and evaluate the potential performance of diverse technologies and practices that reduce greenhouse gas emissions and/or increase carbon sequestration from the atmosphere. These climate solutions span many sectors; all of them are financially viable and already scaling, at least in some places.
Drawdown research fellows analyze solutions, drawing upon years of advanced study, experience, and a wide range of backgrounds. For each technology or practice, we review extensive literature and data describing its potential scale, impact, and cost. We then build analytical models to estimate how many gigatons of carbon dioxide (or equivalent amounts of other greenhouse gases) a given solution could avoid and/or remove over time, as well as the cost (or savings) of implementing and operating it. By integrating the models within and across multiple sectors, we can determine if and when we reach Drawdown under a given scenario.
To provide the world with a current and robust resource, our research team conducts an ongoing review and analysis of climate solutions. We also collaborate with various research partners, including universities, government labs, and non-profit research institutes around the world, as our research continues to expand in scope and depth.
