Project Drawdown's 2020 publication is the first major update to the research and analysis of climate solutions since Drawdown, its 2017 best-selling book. See pages 14 – 49 for a deeper dive on reducing the largest sources of emissions across sectors.
Unit 3: Reducing Sources
Lecture
How can we stop harmful emissions in their tracks? Discover fascinating, up-to-date methods for halting emissions before they reach the atmosphere. This unit walks through the five largest sources of greenhouse gases—electricity, food, industry, transportation, and buildings—bringing the path to a safer, low-carbon economy into sharper relief. Learn which sources make up the biggest slices of the global emissions pie.
