Climate change is one of the greatest environmental challenges of our time. Global warming due to human-generated greenhouse gas (GHG) emissions/carbon emissions, may have severe adverse environmental, social and financial effects if temperatures continue to rise. The 2022 Global Status Report for Buildings and Construction indicates that the sector accounted for over 34 per cent of energy demand and around 37 per cent of energy and process-related CO2 emissions in 2021.
Operational energy-related CO2 emissions reached ten gigatonnes of CO2 equivalent – five per cent over 2020 levels and two per cent over the pre-pandemic peak in 2019. In 2021, operational energy demand for heating, cooling, lighting and equipment in buildings increased by around four per cent from 2020 and three per cent from 2019. A number of reports inlcuding those from the United Nations have suggested that the construction sector is in danger of not being on track to decarbonise by 2050
RICS is at the forefront of calculating, communicating and mitigating against carbon in the built environment. In particular methodologies for assessing whole life carbon within the built environment.
