Begun in 1999, the Cement Sustainability Initiative is a contribution of 10 major cement companies working with the WBCSD toward sustainable development. The purpose of the initiative is to:
- Explore what sustainable development means for the cement industry
- Identify and facilitate actions that companies can take as a group and individually to accelerate the move toward more sustainable practices
- Provide a framework through which other cement companies can learn and participate
- Provide a framework for engaging external stakeholders

The partnership will extend over a number of years as the cement industry develops, implements, and communicates a series of guidelines and good practices to be applied to the areas of (1) climate change management, (2) use of fuels and raw materials, (3) employee health and safety, (4) emissions reduction, (5) land use and local impacts, and (6) internal business processes.
