Last week, Webcor Builders and Climate Earth announced a partnership to create the first database of greenhouse-gas emissions from the construction supply chain. The idea is to measure and catalog carbon footprints created when producing building materials, from glass and drywall to steel and concrete. Webcor says the goal is to establish a consistent means for the construction industry to measure the carbon equivalent of its products. Climate Earth will quantify greenhouse gases that are generated, including during mining, manufacturing and transporting. Data from Webcor’s construction projects and Climate Earth’s Enterprise Carbon Accounting system will quantify the emissions in units
Arch dams, classically curved monoliths situated in narrow valleys, are not as common as other types of dams, such as embankment dams and gravity dams. ENR takes a look at some of the biggest arch dams in the world, both completed and under construction.
