Key Findings from the Intergovernmental Panel on Climate Change Fifth Assessment Report
The Fifth Assessment Report from the Intergovernmental Panel on Climate Change is one of a series of documents synthesizing the most pertinent findings of AR5 for specific economic and business sectors. The world’s buildings account for just under a third of global final energy use and about a fifth of all GHG emissions, although energy use varies widely from region to region. Under business as usual projections, use of energy in buildings could globally double or even triple by 2050. Wide spread implementation of best practices could see energy use in buildings stabilize or even fall by 2050. Buildings offer near-term, highly cost-effective opportunities to curb energy demand growth rates. Exploiting this potential more widely requires sustained policies and actions that address all aspects of the design, construction and operation of buildings and their equipment, as well as changing user behaviour and attitudes.
