Collection of key production data
Restatements

Back to Overview

Index calculation in general, combined product group indices: For a more precise presentation of index developments, the indices of individual areas were combined and calculated in absolute figures; in the past, the calculation was based on weighted production tonnages of the individual product groups. The index data of the previous years were adjusted accordingly to show a three-year trend.

Index of specific CO2 emissions for 2013, Clay Building Materials Europe (CBME): The previous year’s figures were adjusted retroactively, as data registration on the EU server (EUTL) had not yet been completed at the time of publication of the 2013 Sustainability Update.

Production volumes of a single roof tile plant, Clay Building Materials Europe: The management of master data relating to the production volumes of a single roof tile plant of the CBME Division was corrected in 2014; for reasons of comparability, the data for 2012 and 2013 were restated to show a three-year trend.

Coal as fuel, Clay Building Materials Europe: The degree of granularity of data collected on the use of coal as fuel in a single production site has been increased; for reasons of comparability, the data for 2012 and 2013 have been restated to show a three-year trend.

Fuel oil, Steinzeug-Keramo: The degree of granularity of data collected on the use of fuel oil at a single production site of Steinzeug-Keramo has been increased; for reasons of comparability, the data for 2012 and 2013 have been restated to show a three-year trend.
