"Building decarbonization refers to the process of reducing carbon emissions from buildings. Buildings account for a significant amount of global greenhouse gas emissions, primarily from the use of energy for heating, cooling, lighting, and other functions. Decarbonizing buildings is an important strategy to reduce the carbon footprint of the built environment and mitigate the effects of climate change. There are several ways to decarbonize buildings, namely by improving energy efficiency, switching to renewable energy sources, electrification, carbon capture and storage, and green building design and construction. The Infrastructure Investment and Jobs Act (IIJA) includes several programs and initiatives related to reducing carbon emissions and promoting sustainable practices in the construction and building sectors"-- Provided by publisher.
