From the “settled science” department and the University or California Irvine, comes this inconvenient fact. For years we’ve been told by academics that cement is another nasty global warming contributor, because of CO2 released during production.
“Cement manufacturing is responsible for 5 to 8 percent of global CO2 emissions,” notes Del Gado, a theoretical physicist who is part of Georgetown’s Institute for Soft Matter Synthesis and Metrology. “Although there have been calls for creating so-called ‘green cement,’ the sustainability and science communities have yet to find a way to reduce CO2 emissions while retaining the efficiency, durability and cost efficiency of cement. Our study could help change that.”
Now, not so much.
