A cross-industry coalition, representing stakeholders across the built environment, has come together to develop a standard for verifying buildings in the UK as net-zero carbon. 

Called the UK Net Zero Carbon Buildings Standard, it provides a single, agreed methodology for proving built assets are net-zero carbon and in line with the UK’s climate targets. The leading industry organizations behind this initiative include BBP, BRE, the Carbon Trust, CIBSE, IStructE, LETI, RIBA, RICS, and UKGBC. 

The metrics used to evaluate net-zero carbon performance will include energy use, upfront embodied carbon, and lifecycle embodied carbon, along with space heating/cooling demand and peak load. The Standard will cover both new and existing buildings with performance targets that align with Britain’s 2035 emissions target to reduce by 78% and its 2050 net-zero target. It will also cover the procurement of renewable energy and the treatment of residual emissions, including carbon offsetting. The scope and output of the Standard may, however, evolve throughout the development process. 

The methodology will be for anyone who wants to fund, procure, design, specify, or occupy a net-zero carbon building and anyone wanting to demonstrate that their building aligns with the industry-agreed standard. 

“This is a really exciting and timely initiative that will help the entire industry to move forward in its efforts to reach net-zero carbon,” said RIBA President Simon Allford. “Working together we will address current ambiguities around the much-used term and develop a common understanding, based on clear performance targets, to support all those involved in the procurement, design, construction, and operation of buildings.”

The coalition is now seeking support from stakeholders, whether individuals or organizations, across the industry to contribute to the Standard. More details on ways to get involved can be found here, with applications due June 6th.
