Title: German Cement Industry’s Voluntary Efforts on the Issue of Climate Change-A Success Story
Author(s): V. Hoenig and M. Schneider
Publication: Special Publication
Appears on pages(s): 15-32
Keywords: CO2 emissions; cement; clinker; Kyoto Protocol
Abstract:In 1995 the German cement industry committed itself to a 20 % reduction in it’s specific fuel energy consumption between 1987 and 2005. In 2000, this commitment has been adapted to the international agreements, particularly to the Kyoto Protocol. Now the voluntary agreement includes a reduction of the specific energy-related CG2 emissions from 1990 to 2008/12 by 28 %. As the burning and grindrng facilities have been widely optimized during the past years, the German cement industry is planning to increase the sub-stitution of fossil fuels by waste fuels and to promote the marketing of blended cements. From 1987 to 1999 the German cement industry’s efforts have led to a reduction of the energy related CO, emissions by 3,6 million ton-nes per year. The share of waste fuels has been increased from 4 to 23 % and the clinker portion in cement has been decreased from 86 to 80.6 % by using more granulated blast-furnace slag and unburned limestone as the main constituents in cement. To what extent other instrument like emission trading, joint imple-mentation or clean development mechanism can be used in the future to achieve further reductions, will depend on mutual arrangements and implementation by the international community.
