The General Services Administration is doubling down on its efforts to slash greenhouse gas emissions from federal buildings with recent announcements aimed at both procuring carbon-free energy and testing out new energy-efficient, low-carbon technologies.

Bills moving forward could introduce voluntary time-of-use rates in the state, disclosure statements about green power and point-of-sale EV rebates.

With more than 300,000 buildings, the U.S. government is the nation’s largest energy consumer and “a steady customer prepared to make long-term investments,” GSA Administrator Robin Carnahan said.
