In booming economies from Asia to Eastern Europe, cement is the glue of progress... But making cement creates pollution, in the form of carbon dioxide emissions, and the greenest of technologies can reduce that by only 20 percent...[and] cement has no viable recycling potential... Many of the world's producers acknowledge the conundrum... Olivier Luneau, head of sustainability at Lafarge...[said] "Because of our initiatives, emissions are growing slower than they would without the interventions."... Lennard De Klerk, director of Global Carbon...[said] "All the big cement companies, like Lafarge and Heidelberg Cement, have bought existing facilities [in Eastern Europe] that generally use fairly outdated technology and that waste a lot of energy."
