The sector is among the major contributors to global greenhouse gas emissions, with cement alone accounting for about 7% of carbon dioxide (CO2) emissions according to the International Energy Agency. Material impacts from the transition to a low-carbon economy are most likely in high-emitting industries such as cement, where cost increases, including from potential carbon taxes and energy prices, could transform companies' financial and business profiles over the next decade. Yet, since buildings are responsible for about 40% of the world's carbon emissions, the sector could benefit from regulation and government measures to improve buildings' energy efficiency, which have led to volume growth of related services and products like insulation, particularly in the EU and U.S.
