The so-called “Earthshot” goal from the Energy Department also aims to reduce the upfront cost of cutting emissions from affordable homes by half over the same time period.
It is one of several energy and climate-related research and development goals laid out by the administration.
According to the Energy Department, almost a third of the country’s planet-warming emissions come from buildings. Millions of U.S. households also fell behind on their energy bills last year.
“The windows, walls, and roofs that protect our families from the elements and keep us healthy and safe are some of the most effective tools we have to lower our utility bills fight climate change and advance environmental justice,” Energy Secretary Jennifer Granholm said in a statement.
While the research and development goals are unlikely to generate much political pushback, the administration’s other efforts to decarbonize homes — especially efforts to mandate that new appliances be more efficient — have spurred controversy.
