Top 10 Solutions to Reverse Climate Change

Reading Time: < 1 minute

By Paul Hawken and the Project Drawdown experts thought they knew what to expect when they modeled and ranked 80 solutions that could reverse global warming. But the data had some surprises in store. Most prominently was that even when the solutions are modeled in terms of what they call a “Plausible Scenario”—a conservative measure of projected solution implementation that is “reasonable yet optimistic”—society still makes great strides toward achieving drawdown, the point where greenhouse-gas levels in the atmosphere begin to decline. Together, all 80 reduce or sequester carbon by 1,051 gigatons by 2050 in the Plausible Scenario. Using the scenario that gets us to drawdown—which requires ramping up the solutions a bit more than the conservative measure, particularly renewable energy—they reduce or sequester carbon by 1,442 gigatons by 2050. Below are the top ten solutions, ranked in terms of emissions reduction potential over a 30-year period. For the other 90 solutions, we highly recommend you read Drawdown: the Most Comprehensive Plan Ever Proposed to Reverse Global Warming (Penguin Books, 2017), edited by Paul Hawken. —the Green America editors 1.
