The International Union of Architects (UIA) has made a major commitment to do its part in the fight against climate change. At its recent World Congress in Durban, South Africa, the Union—which represents 1.3 million architects from 124 countries—universally pledged to eliminate carbon emissions from the built environment by 2050. The “2050 Imperative” was created by the non-profit Architecture 2030 and approved by the UIA on August 8th.
The New York Times reports on a company called Calera, which says it can capture carbon dioxide emissions from coal and gas power plants and inject it into concrete. The company is pretty secretive about the process, but says that it combines carbon dioxide with seawater or groundwater brine, leaving calcium carbonate and magnesium carbonate, which are used in making cement. Many are skeptical that they can do this on a large scale, though, and others wonder about new environmental problems, like the creation of harmful acids. But if their claim is legit it could be a major boon to environmentalists and to the construction industry. This could be construction’s version of the Bloom box, which is essentially a little power plant in a box. What other inventions will transform our industry? Any ideas? Please chime in..
