Air emissions

Like many energy intensive manufacturing industries, cement production generates emissions other than CO2.

CSI guidelines have been developed to provide member companies with an agreed common protocol on how to monitor and measure air emissions, including micro-pollutants. Collaborative works with universities and trade association, such as a study with the United Nations Environment Program (UNEP) on persistent organic pollutants (POPs), and with CEMBUREAU and the University of Liège on mercury have helped to identify best practice and establish control techniques to minimize emissions.

The risks associated with the release of mercury and its compounds on people's health and the environment is of great concern to stakeholders, in particular local communities and regulatory authorities.

National or regional legislation are already in place, and work has started under the umbrella of UNEP, supported by the CSI, on two parallel tracks:

  • The Intergovernmental Negotiating Committee (INC), whose work aims at delivering a global, legally binding instrument to manage mercury emissions from the different sectors.
  • The Global Mercury Partnership, which will deal mainly with dialogue and experience sharing in various industry sectors on the management of mercury and its compounds from different activities. This partnership process will feed information and data into the decision making process of the INC track.
