The Royal Institution of Chartered Surveyors (RICS) has announced the launch of the Coalition for Life Cycle Emissions Alignment and Reporting (CLEAR), a global initiative intended to harmonise the measurement and reporting of whole-life carbon emissions across the built environment in different markets and jurisdictions, while helping to accelerate progress towards decarbonisation targets. CLEAR has been established with co-founders, the World Business Council for Sustainable Development and the Global Building Data Initiative, with Autodesk as sponsor, and will collaborate with industry partners, including AECOM, Arcadis, Avison Young and Heidelberg Materials, among others. CLEAR will also support the sector through practical tools and an online platform designed to build capability and encourage uptake. In its first year, CLEAR will focus on analysing existing whole-life carbon assessment methodologies and identifying key differences, as well as developing resources for industry and policy stakeholders. Its longer-term ambition is to support a harmonised global framework that enables more effective reporting and more confident carbon-related decision-making across the built environment.
