Cement makers eye big cuts to greenhouse gases

By Pete Harrison

BRUSSELS (Reuters) - Nearly a third of the world's cement industry has united on a strategy to cut global warming gases in a way that will not slow a construction boom in poor countries, backers of the initiative said on Wednesday.

The cement sector contributes about 5 percent of global carbon dioxide emissions -- well ahead of other manufacturers except steel and refineries -- and is expected to double its capacity by 2030 amid rapid urbanization in developing nations.

The Cement Sustainability Initiative (CSI), whose 18 members produce about 30 percent of the world's cement, unveiled its vision of a "sectoral approach" to tackling carbon dioxide (CO2), the main gas that scientists blame for dangerously heating the atmosphere.

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 percent, compared to a situation where there are no commitments to carbon reduction," CSI program director Howard Klee said.

Klee said the approach would help win the backing of poor countries, which have rejected any absolute cap on emissions.

DEVELOPING COUNTRIES CRUCIAL

"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.
