Energy use and CO2 emissions for Mexico's cement industry

Energy use and CO 2 emissions in the Mexican cement industry are analyzed for the period 1982–94. Using the Laspeyres index method, we estimate the relative importance of fuel intensity, clinker activity, the cement/clinker ratio, and the use of waste tires as an alternative fuel in the changes of clinker fuel use.
