Does clearing trees for solar panels release more CO₂ than the solar panels would prevent?

Clearing trees to build solar farms does not negate their climate change benefits, because one acre of solar panels prevents far more CO₂ emissions than an acre of forest absorbs.

In the U.S., replacing equivalent natural gas power with one acre of solar prevents about 175 to 198 metric tons of CO₂ emissions per year.

In contrast, an average acre of forest sequesters less than 1 metric ton of CO₂ per year. An acre of solar cuts roughly 200 times more CO₂ than an acre of trees.

Cutting forest does release stored carbon, but even if all 304 metric tons of CO₂ in a forested acre were emitted during construction, a typical solar farm would offset that within two years of operation.

Only about 4% of U.S. solar projects have been built on forested land.

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.
