Drawdown Science

Key Report Takeaways:  Black carbon is a powerful climate pollutant which stems from the incomplete combustion of fossil fuels and biomass Black carbon has unparalleled impacts on human well-being, the environment, and climate change   Black carbon has a short-term warming potential up to 1,500 times greater than carbon dioxide and is responsible for millions of premature deaths annually worldwide Black carbon emissions are highest in low- and middle-income countries with half of all emissions coming from just five countries Around 48% of all black carbon emissions are attributable to the residential sector, particularly from the use of dirty cooking fuels Targeted solutions across the residential, transportation, and industrial sectors in high-emitting regions would dramatically reduce black carbon emissions while preventing millions of premature deaths and saving trillions of dollars per year  In a report published today, scientists from Project Drawdown, the world’s leading resource for climate solutions, provide the most comprehensive look yet at how addressing black carbon – more commonly known as soot – would reduce global warming while preventing millions of premature deaths and saving trillions of dollars annually worldwide.  Black carbon, which largely results from the incomplete combustion of fossil fuels and organic matter used for cooking, transportation, industrial production, and more, is a major pollutant and greenhouse gas with a short-term warming potential up to 1,500 times greater than carbon dioxide.  Worldwide, black carbon is responsible for millions of premature deaths annually, increasing the risk of cardiovascular, respiratory, and other diseases. This results in the loss of trillions of US dollars globally in economic productivity each year. These impacts are felt most acutely in low- and middle-income countries, which still rely heavily on unclean fuels, such as wood, for heating, cooking, and energy production.  In the groundbreaking report, Project Drawdown researchers highlight global hotspots and sources of black carbon across geographies providing policymakers and funders with the best insight yet into what solutions, deployed where, will result in the greatest emissions reductions.

Halting climate change, alleviating poverty, and stemming the loss of biodiversity are some of the most critical challenges humanity faces today. With finite resources to invest in addressing them, how do we decide where to focus our efforts? Good news: We don’t have to pick one or another! Project Drawdown has identified a set of specific technologies and practices that address multiple challenges simultaneously and synergistically, creating an exciting opportunity for funders and development agencies to dramatically amplify impact while working to address the world’s most pressing needs. In this latest Drawdown Ignite webinar, climate-poverty solutions scientist Yusuf Jameel and policy advisor Dan Jasper introduce these “triple-win” solutions and explore how strategic deployment in low- and middle-income countries can bring new hope for a better world within our lifetimes. Top Takeaways Solutions to three massive threats humanity faces today – climate change, poverty, and biodiversity loss – overlap, and numerous actions can address all three at the same time. Efforts to alleviate poverty can increase or decrease demand for fossil fuels. As development proceeds, it’s critical to avoid “carbon lock-in” by favoring renewable over carbon dioxide–producing technologies. Climate change and biodiversity loss are intricately intertwined. Climate change exacerbates biodiversity loss, and biodiversity loss exacerbates climate change. Thus, efforts to alleviate both simultaneously can have synergistic effects. For greatest impacts, funding and action should focus on solutions that address multiple challenges at the same time. For example, shifting agricultural practices to reduce greenhouse gas emissions can also enhance food supply, improve gender equality, and protect habitat. The ability to do so is unfortunately limited by inadequate funding, inappropriate use of available funding, and inequitable distribution of available funding. Solutions include increasing funding for projects that address multiple challenges simultaneously, living up to funding pledges, increasing accountability to ensure funds are appropriately distributed, basing funding decisions on sound science, pursuing the greatest good rather than the greatest profit, and canceling debts owed by low and middle-income countries.  Anyone can help by sharing this message with policymakers and joining advocacy organizations that recognize the importance of and promote intersectional action.

Humanity CAN halt climate change before it’s too late – but to do so, we must be strategic about what, where, and how to focus our efforts for the biggest impact. That’s the take-home message keynote speaker Jonathan Foley, executive director of Project Drawdown, shared at the Nest Climate Campus during Climate Week NYC 2023 in September. “I think we have a real shot at this, but how do we get there?” Foley asked the standing-room-only crowd of sustainability leaders from business, government, academia, and more. The first thing, he said, is to “look at what science is telling us about solutions.” Then we need to figure out which solutions are most economical and effective in various locations and prioritize accordingly – with an eye to enhancing human well-being at the same time. Foley pointed to the Drawdown Roadmap, Project Drawdown’s new strategic plan for deploying climate solutions to achieve global goals by 2050, as the guide humanity needs now to effective climate action. To solve climate change before it’s too late, Foley said, we need to focus mitigation efforts on solutions that are based in sound science, affordable, deployable, geographically appropriate, right-sized, and beneficial to people and other living things. In addition, we need to align how we allocate time, money, and other resources to various solutions with the solutions’ relative impact.
