Lendlease unveiled a new protocol to monitor, measure, and disclose Scope 3 carbon emissions and called on built environment industry leaders to tackle this challenge.
Scope 3 emissions are indirect emissions that occur in an organization’s value chain and often make up the majority of an organization’s carbon footprint. Lendlease says Scope 3 emissions comprise about 90% of its global carbon footprint.
Scope 3 emissions data, embedded in carbon-intensive materials such as steel, cement, aluminum, and glass, are especially challenging to track and measure. They have multiple source points and different levels of transparency, completeness, and assurance. Methods and standards for their calculation are inconsistent, and there is no standardized data exchange for them.
Lendlease is driving to change that with its new protocol that includes a Scope 3 Reporting Assessment Tool with more than 50 possible subcategories.
“We want the protocol to spark conversation and engagement across our sector, to help drive to a consensus on how to account for and report on Scope 3 emissions,” said Cate Harris, group head of sustainability. “If we can achieve this, then we can collaborate as an industry to solve the two big systemic challenges: the decarbonization of harder to abate materials, and the digitization and sharing of Scope 3 emissions data.”
