Classification of economic activities

Unless specified otherwise, the economic activities of the chemical, plastics and life sciences sector fall under:

  • NACE 20: manufacture of chemicals and chemical products;
  • NACE 21: manufacture of basic pharmaceuticals products and pharmaceutical preparations;
  • NACE 22: manufacture of rubber and plastic products.

The NACE code is a numerical code of the European Union used for classifying economic activities. Since 1 January 2008, the revised NACE code ‘Rev. 2’ has been in effect.

Statistics from foreign trade
The products of the chemical, plastics and life sciences sector fall under:

  • section VI: products from the chemical and related industries;
  • section VII: plastic, rubber and their derivatives.

Statistics in this report concerning foreign trade come from the Combined Nomenclature, which is a classification used by the World Customs Organization (WCO).

Environmental indicators
With regard to environmental indicators, this report employs either those reported in the European Pollutant Release and Transfer Register (E-PRTR; 2007-2013), or the official federal or regional sources.

The E-PRTR replaces the European Pollutant Emission Register (EPER). That system gathered data from 2001 to 2004. The number of companies and pollutants, but also the reporting thresholds may differ, which means that the old and new data must be interpreted with the necessary caution. This is certainly the case for data dating from before the initial year of the ‘Responsible Care’ programme (1987).

Production index
The present sustainability report uses the production index in the environmental graphs to demonstrate the decoupling between production and consumption or emissions.

The production index are statistics describing the changes in an industry’s production volume. Since the Sustainable development report 2013, the most recent reference year, i.e. 2010, has been used.
