Wind turbines generate emissions during construction and transportation, but their overall climate impact is far lower than that of fossil fuels.
“Lifecycle emissions” is a measure of all emissions from raw materials, manufacturing, transportation, installation, operation, and disposal. A National Renewable Energy Laboratory review estimates that wind power produces about 13 grams of CO2-equivalent per kilowatt-hour over its full lifecycle. Natural gas averages about 486 grams, while coal is roughly 1,001 grams–or about 77 times wind’s emissions.
Most wind power emissions occur before turbines begin generating electricity, mainly from transporting components and to a lesser degree, manufacturing. Once operating, turbines generate electricity without directly burning fuel, allowing their low-emissions electricity to offset the emissions associated with their production and transportation.

About fact briefs published on Gigafact
Fact briefs are short, credibly sourced summaries that offer "yes/no" answers in response to claims found online. They rely on publicly available, often primary source data and documents. Fact briefs are created by contributors to Gigafact — a nonprofit project looking to expand participation in fact-checking and protect the democratic process.
