FACT BRIEF

Do buildings contribute a significant share of all US greenhouse gas emissions?

YES

According to a report by the bipartisan Environmental and Energy Study Institute, residential and commercial buildings are responsible for nearly 40% of U.S. greenhouse gas emissions, accounting for "direct" emissions (i.e., gas cooktops) and "indirect" emissions (i.e., the production of electricity used in buildings). Most electricity used in the U.S. still comes from fossil fuels, contributing to greenhouse gas emissions.

Energy is also consumed in making and transporting construction materials like wood, steel and glass.

The Environmental Protection Agency attributes 12% of 2018 emissions directly to the commercial and residential sectors (and the buildings they occupy). Portions of emissions measured by the EPA from the electricity sector (27%) and the transportation sector (28%) can be factored in as indirect emissions.

This fact brief is responsive to conversations such as this one.

ABOUT THE CONTRIBUTOR
Gigafact
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
