The Biden administration on Thursday offered up a definition for what is considered a zero-emission building, as part of an effort to reduce building emissions around the country.
The new definition is completely voluntary — but seeks to help industry figure out how to move toward cutting the structures’ contributions to climate change.
“The National Definition of a Zero Emissions Building will support the sector as it advances innovative solutions essential to creating resilient communities and high-quality jobs,” Energy Secretary Jennifer Granholm said in a written statement.
In order to be considered zero-emission, a building must be energy efficient, have no onsite emissions from its energy use and be powered only by carbon-free power sources.
When accounting for both direct and indirect emissions (like electricity usage), residential and commercial buildings made up 31 percent of the U.S.’s planet-warming emissions in 2022.
The administration separately issued another voluntary effort aimed at helping the private sector operate in a more climate-friendly manner last week: laying out principles for carbon credit integrity.
