Project Drawdown

Project Drawdown is a U.S.-based nonprofit focused on science-based solutions to climate change. The organization – focused on

Nine Sectors

The website lists nine sectors where immediate action is needed to limit climate change. They are: # Electricity: Electricity production gives rise to 25% of heat-trapping emissions globally. # Food, Agriculture, and Land Use: Agriculture and forestry activities generate 24% of greenhouse gas emissions worldwide. # Industry: Industry is responsible for 21% of all heat-trapping emissions. # Transportation: This sector is responsible for 14% of global greenhouse gas emissions. # Buildings: Buildings produce 6% of heat-trapping emissions worldwide. # Health and Education: Climate and social systems are profoundly connected, and those connections open up solutions that are often overlooked. # Land Sinks: While the majority of heat-trapping emissions remain in the atmosphere, land sinks return 26% of human-caused emissions to Earth. # Coastal and Ocean Sinks: Oceans have absorbed at least 90% of the excess heat generated by recent climate changes and have taken up 20–30% of human-created carbon dioxide. # Engineered Sinks: The sheer quantity of excess greenhouse gases means that natural processes cannot do it all when it comes to carbon sequestration. Developing technologies show promise to help supplement previously mentioned natural sinks.

Book

''Drawdown Review''

A 2020 review of the findings of the research that led to the 2017 book was published as a 104-page PDF in 2020.
