One culprit for climat change that hasn't really been talked about
Cement, which is used to make concrete, makes up 5 percent of global CO2 emissions, more than the airline industry. This good article from the New York Times (thanks to Bru Notes) shows some of the inherent contradictions involved. While the world's largest cement maker, LaFarge, is pursuing green initatives in lowering emissions, this can be considered to be largely meaningless as they're making more cement than ever before. And some of the places where they're making this cement, like Ukraine, aren't regulated.
