Decarbonization is inextricably linked to energy efficiency and renewable energy. Removing carbon from the building sector requires that buildings use less energy overall, through energy efficiency retrofits, and clean solar PV energy must be used as the energy source for all buildings.
Energy efficiency and renewable energy used properly together is like the use of stealth technology in the defense industry. Reducing your carbon footprint is like reducing a fighter jet’s “radar signature”, making it easier to elude the catastrophic effects of climate change.
The Intergovernmental Panel on Climate Change (IPCC) concluded that, “Building emissions [have] to be reduced by 80-90 per cent by 2050…” and that, “New construction [has] to be fossil-free and near-zero energy by 2020…” to limit global temperatures to a 1.5°C increase and avoid the worse impacts of climate change.
Deep cuts in greenhouse gas emissions from the global economy are required by 2030, with net zero emissions by 2050. This enormous challenge can only be tackled by governments, businesses and civil society working together to take ambitious action to radically reduce emissions.
“Reducing greenhouse gas emissions to zero is bigger than anything humanity has done to date.”
Globally, the World Green Building Council has set a target for all buildings to be net zero carbon by 2050, in line with the Paris Agreement’s climate change goals.
