Building Decarbonization
Overview
Decarbonized buildings incorporate energy efficiency upgrades, electrification, and design elements which can drastically lower U.S. energy demand while providing benefits such as cost savings, carbon pollution reduction, and improved indoor air quality. Commercial and residential buildings account for ~13% of U.S. emissions, largely due to burning gas, diesel, or heating oil. States that are proactive about building codes and standards can reduce emissions while creating jobs in retrofitting and weatherization.
