ALT Greenhouse gas emissions caused by the construction of new buildings and infrastructure, known as ‘embodied carbon emissions’, are a significant driver of climate change. ​ These emissions amount to just under 50MtCO2e per year in the UK, a shocking figure that is vastly in excess of 10% of our national emissions. ​ For context; there are 149 countries in the world whose entire national carbon footprint is smaller than the footprint of the UK's construction sector. Despite this, embodied carbon emissions are unregulated in the UK. Current policy and regulation focuses solely on operational energy use, as distinct from embodied carbon, and there are currently no national planning policy or Building Regulation requirements to assess, report or reduce embodied carbon emissions. ​ This must change. So ACAN is calling for the urgent introduction of legislation to regulate embodied carbon emissions in the UK. Our demands are backed up by a report, and now we need your help.
