Governments, building organisations and funding agencies yesterday launched the Global Alliance for Buildings and Construction, a worldwide building network aiming to drastically reduce the sectors’ greenhouse gas emissions.
The Alliance and was launched at the first ever United Nations (UN) Buildings Day held during the 21st Conference of the Parties (COP21), where governments and businesses are in Paris negotiating an historic new agreement to mitigate climate change.
The major objective is of the Alliance is to work with the buildings and construction sector to limit global warming to <2oC by cutting greenhouse gas (GHG).
To be on this path requires reducing global energy and process-based CO2 (carbon dioxide) emissions by 60% in 2050 compared to 2012. For the building sector this means avoiding at least 50% of projected growth in energy consumption through mainstreaming of highly energy-efficient, near or net-zero energy or energy-plus new buildings, and a deep renovation of the existing stock of buildings by 2030.
The Alliance recognises that the buildings and construction sector is at the centre of economic growth globally. However, the sector is one of the biggest emitters of carbon dioxide, a major cause of global warming.
The commitments made by governments at COP21 require consistent instruments to monitor and measure progress and international standards that measure buildings and construction materials consistently underpin these global climate goals.
