The Cement Sustainability Initiative (CSI) unveiled its vision of a "sectoral approach" to tackling CO2.
The project has built a system for monitoring, reporting and verifying CO2 and aims to share technology and best practice for cutting those emissions amid a myriad of regional and global regulations, caps and curbs.
"CO2 emissions might be reduced by as much as 25 per cent, compared to a situation where there are no commitments to carbon reduction," CSI programme director Howard Klee said.
Klee said the approach would help win the backing of poor countries, which have rejected any absolute cap on emissions.
"It is critical to get developing countries involved, because that’s where 80 percent of cement is made and that is projected to increase to 90 percent by 2030," he added.
"Just because Europe is about to cut emissions, that isn’t going to prompt India, for example, to do the same."
Further cuts could be made by using biofuels to generate heat and burying the CO2 using nascent carbon capture and storage technologies.
