Lack of information on carbon emissions challenges construction industry

Less than 1% of new building projects are assessed to determine their carbon footprint, according to a new report by the World Business Council for Sustainable Development.

The report cites a lack of information on embodied emissions as a key barrier. The overcome this challenge, the report calls for more data sharing, more collaboration, and increased transparency on embodied carbon and other data critical to calculating the carbon footprint of new buildings.

Half of all emissions are embodied in buildings—caused by the manufacturing of materials and the construction process—the report says. The report also calls for the industry to adopt whole-life carbon assessments and set clear targets for decarbonizing construction.

There are about 255 billion square meters of buildings in the world, with an additional 5.5 billion square meters added each year. That is equivalent to a city the size of Paris being constructed every week.

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.
