What can be done to reduce GHG emissions in the cement industry profitably?

After review of the entries, the Judges in the Profitably reducing emissions from cement contest have chosen not to award any finalists or winners. While the entries presented interesting ideas, the Judges deemed the challenges associated with implementing those ideas as being too great to warrant further development of the proposals.

Cement is one of the most carbon-intensive industries and in 2020 will account for as much as 5 gigatons of CO2 emissions. But aggressive pursuit of proven measures could reduce 2020 emissions from cement production by nearly a gigaton. This contest seeks proposals on how to stimulate investment in profitable carbon intensity reduction measures. The winner will receive travel expenses to present their ideas at Carbon War Room’s Creating Climate Wealth May 2013 summit in Singapore. See more...
