Energy consumption in buildings and constructions represents 32% of the global energy consumption ahead of transport (27%) and industry (29%). Moreover, the buildings sector accounts for half of electricity consumption and contributes to 19% of the greenhouse gases (GHG) emissions worldwide. Because of a growing population, as well as structural changes in many economies, energy demand in buildings is expected to rise, as the global real estate is expected to double to reach over 180 billion m² by 2050. Furthermore, buildings will particularly be affected by the effects of climate change: flooding and seepages, reduction of the durability of building materials, increase in the risk of collapse all reducing building lifetime, and health-related risks. The buildings and construction sector still has to improve appropriate standards to adopt a universal decarbonisation target path (IEA, ETP 2016). Yet, many solutions are available, and the economic, health, and social benefits of sustainable buildings are significant, and have been demonstrated in most regions of the world. With early and efficient policies, the buildings and construction sector should therefore be more fully engaged in climate commitments. Actually, energy savings and related-carbon emission reductions that can be achieved through buildings represent a huge potential. Ambitious actions on buildings and construction, deep retrofit of existing buildings, ceiling of new buildings emissions, are possible to achieve global warming limitation. Ensuring access to a comfortable and healthy habitat, saving natural resources and emitting less GHG, is a challenge for all stakeholders. Governments are responsible for creating favorable conditions through regulations, fiscal or financial incentives, and strategies. Local authorities and private partners together are the key actors for a successful transition towards low-carbon real estate. Many commitments have been made, especially during the COP 21 in Paris. Many existing initiatives already target separately the mobilization of the players or local authorities. The Global Alliance for Buildings and Construction, in Climate Chance Forum, gathers major initiatives on sustainable buildings and energy efficiency in buildings to allow dialogue and create a common action. To this purpose, it appeared useful to provide clarity and visibility on initiatives intending to support local authorities in their action to decrease GHG footprint of the building sector. We hope to enrich and update it each year with more results and actions.
