We first dive deep into what it means to reverse global warming and Project Drawdown’s initial most impactful project list. Here’s what they say in Drawdown Review about the original 2017 list, the one that served as the basis for our previous episode: “The solutions content in the original book remains robust and relevant and its broader lessons still hold.” So that means the content in our original Reversing Global Warming episode is still robust and relevant, as well as urgent. We can reach Drawdown by mid-century if we scale the climate solutions already at handĬlimate solutions are interconnected as a system, and we need all of them. Two insights we want to share here are:ĭrawdown is the future point in time when levels of greenhouse gases in the atmosphere stop rising and start to steadily decline. The top ten insights are listed at the beginning of the review. They anticipate regular publications going forward so be on the lookout for more Project Drawdown. The new solution categorization and impact modeling is detailed in The Drawdown Review, which was published in 2020 and represents Project Drawdown’s best assessment of climate solutions for 2020. Google, Lime, IDEO and many others are already involved. In short, Project Drawdown is challenging the business world to go beyond “do less harm.” They’re asking companies to go beyond their own footprints and bring their resources, employees, and influence to solve the problem. In October 2020, it announced Drawdown Labs, a consortium of private sector partners working to go beyond ‘net zero’ to scale climate solutions in the world, within and outside their own operations. Project Drawdown is also now engaging the private sector in a big way. This is a living document so do keep checking their website as no doubt things will change as they continue to research and model. Also, some solutions may quickly achieve a certain amount of emission reduction or storage and then not deliver much more without a high degree of effort. Consider how certain solutions are better positioned to achieve high amounts of emission reduction or storage at lower cost. The solutions that are most economical fluctuate depending on the scenario. Each scenario requires a certain amount of emissions to be reduced or stored to achieve a temperature reduction goal. Drawdown is all about implementing solutions that are plausible and economic. It can be a little confusing why the top 3 solutions change by scenario. All of the solutions and both scenarios are plausible and economic. We link to all the solutions in our show notes for you to check out. The 2 degree Celsius scenario shows reduced food waste, health and education, and plant-rich diets as the top three. The 1.5 degree Celsius scenario shows onshore wind turbines, utility-scale solar photovoltaics, and reduced food waste as the top three in terms of gigatons of CO2 equivalent reduced or sequestered. One scenario that is in line with a 1.5 degree Celsius temperature rise by 2100 and another scenario that is in line with a 2 degree Celsius temperature rise by 2100. Major bucket here is health and education.Īnd don’t worry they still rank the solutions by impact. This involves uplifting the ways nature takes in carbon.Įxamples here are the soil and the ocean, as well as engineered sinks that remove and store carbon. Think electricity, buildings, and transportation. They now break down the solutions into three buckets: sources, sinks, and society.īasically reducing or removing the actions that are the cause of carbon emissions. Since we talked with Paul, Project Drawdown has been busy.įirst of all, you won’t find that list of 100 solutions on its website anymore. It ranked and detailed the top 100 solutions to climate change that will eliminate carbon from our atmosphere. The book Project Drawdown was published in 2017. We released an episode titled “Reversing Global Warming” in June 2018 that focused on the book Project Drawdown and featured an interview with its author Paul Hawken.
