The document summarizes a call to action from representatives in the real estate and building industry for immediate steps to mitigate and adapt to climate change. It notes that buildings are responsible for 40% of global energy use and up to 30% of greenhouse gas emissions. The building industry can deliver significant emissions reductions at low cost using available technologies. It requests that parties to the UNFCCC climate change framework recognize buildings as a top priority and support measures to encourage investment in energy efficient building projects. Industry representatives commit to actions like retrofitting existing buildings, mandating net-zero energy performance for new public buildings, and dedicating research to climate neutral construction.
