Lendlease launches new protocol for Scope 3 carbon reduction

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.”

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
