This decade is crucial for implementing the measures required to achieve the targets of all new buildings and 20% of the existing building stock being zero-carbon-ready 2 by 2030.ġ Energy sector CO 2 emissions include emissions from energy combustion and industrial processes.Ģ Zero-carbon-ready buildings are highly energy-efficient and resilient buildings that either use renewable energy directly, or rely on a source of energy supply that can be fully decarbonised, such as electricity or district energy. Yet the sector needs more rapid changes to get on track with the Net Zero Emissions by 2050 (NZE) Scenario. Minimum performance standards and building energy codes are increasing in scope and stringency across countries, and the use of efficient and renewable buildings technologies is accelerating. In 2022, buildings sector energy use increased by around 1%. Direct emissions from the buildings sector decreased in 2022 compared to the year before, despite extreme temperatures driving up heating-related emissions in certain regions. The operations of buildings account for 30% of global final energy consumption and 26% of global energy-related emissions 1 (8% being direct emissions in buildings and 18% indirect emissions from the production of electricity and heat used in buildings).
