The World Green Building Council’s pioneering report “Bringing Embodied Carbon Upfront: Coordinated action for the building and construction sector to tackle embodied carbon” demands radical cross-sector coordination to revolutionise the buildings and construction sector towards a net zero future, and tackle embodied carbon emissions.
Through the Advancing Net Zero project, and in partnership with European Climate Foundation, Children’s Investment Fund Foundation, C40 Cities and Ramboll, this WorldGBC ‘call to action’ report focuses on these emissions, as part of a whole lifecycle approach, and the systemic changes needed to achieve full decarbonisation across the global buildings sector.
Buildings are currently responsible for 39% of global energy related carbon emissions: 28% from operational emissions, from energy needed to heat, cool and power them, and the remaining 11% from materials and construction.
Towards the middle of the century, as the world’s population approaches 10 billion, the global building stock is expected to double in size. Carbon emissions released before the built asset is used, what referred to as ‘upfront carbon’, will be responsible for half of the entire carbon footprint of new construction between now and 2050, threatening to consume a large part of our remaining carbon budget.
Therefore the built environment sector has a vital role to play in responding to the climate emergency, and addressing upfront carbon is a critical and urgent focus.
In the report, WorldGBC has issued a bold new vision that:
- By 2030, all new buildings, infrastructure and renovations will have at least 40% less embodied carbon with significant upfront carbon reduction, and all new buildings are net zero operational carbon.
- By 2050, new buildings, infrastructure and renovations will have net zero embodied carbon, and all buildings, including existing buildings must be net zero operational carbon.
The report is critical to create a conversation around the value and importance of embodied carbon, with the aim of creating and stimulating market demand for transparency, improvements, and verification of embodied carbon reductions.
WorldGBC engaged with over 200 stakeholders throughout the process to produce the report and at the time of release has garnered over 80 endorsements from across the entire building and construction value chain including developers and construction companies, financial institutions, city networks and government, as well as industry representatives from concrete, steel and timber and many more.
