For a chemical company safety and environmental protection are not only critical objective with equivalent targets. Those targets also have to be defined with key performance indicators (KPIs). To record global KPIs systematically in the areas of safety and environmental protection LANXESS uses an electronic system. This proprietary system enables to define a broad range of KPIs for each business unit and location worldwide. These provide a valid database for internal and external reporting and map the progress LANXESS is making towards achieving globally applicable HSEQ objectives.
In the year under review, auditors KPMG AG Wirtschaftsprüfungsgesellschaft assessed our data recording processes and system in the course of a business audit. Most of our HSE indicators for 2010 and 2011 were tested with a view to achieving a “reasonable assurance” rating.
HSE performance indicators are adjusted every year and reported in the Annual Report. Data recording in 2011 was aligned with GRI G3 standrd. The current performance indicators for 2011 in accordance with GRI G3 can be viewed in the table below.
Explanations concerning our environmental and safety performance data
*) The aggregate data refer to all LANXESS production sites in which the company holds an interest of more than 50 percent, but excluding the site at Redmond, U.S.A. The new Keltan sites (since May 2, 2011) at Geleen, Netherlands, and Triunfo, Brazil, and the Darmex sites assigned to Rhein Chemie (since January 11, 2011) at Burzaco and Merlo, Argentina, and
Colonia, Uruguay, are already included. The newly acquired Unitex site at Greensboro, U.S.A. (since October 2011) and the Verichem site at Neville Island, near Pittsburgh, U. S. A. (since November 9, 2011) were not included in 2011. On account of limited recording and control options and the resulting estimates, the base data contain some inherent uncertainties.
Data recording in 2011 was aligned with GRI G3.
+) Indicator was assessed (limited assurance) by KPMG AG Wirtschaftsprüfungsgesellschaft in the course of a business audit.
++) Indicator was assessed (reasonable assurance) by KPMG AG Wirtschaftsprüfungsgesellschaft in the course of a business audit.
1) LTIFR: accident rate per million hours worked resulting in one working day or more lost following the day of the accident, calculated for all employees (including subcontract workers) at all sites
2) Volume sold of goods manufactured by LANXESS and sold internally to another LANXESS company or externally (excluding commercial products)
3) Values corrected compared to the values shown in the Annual Report 2010
4) All Scope 1 Kyoto gases are calculated as CO2 equivalents (CO2e). In accordance with the GHG Protocol, the CO2 emissions from the combustion of biomass are shown separately and are not included in the Scope 1 emissions. The following emissions were produced during the reporting period: 2010: 153 kt CO2; 2011: 241 kt CO2.
5) Total VOC (volatile organic compounds) excluding methane and acetone
6) Nitrogen oxide (NOX) calculated as NO2 (excluding N2O - nitrous oxide)
7) Sulfur dioxide (SO2) + SO3 calculated as SO2
8) Equivalent to circulating cooling water
9) The energy volumes given were calculated on the basis of simplified assumptions and typical substance values. They do not include other forms of imported energy (e.g. the energy contained in raw materials).
10) Significant increase compared to the published value on the basis of the full inclusion of the CO, NOX and SO2 emissions from the use of renewable energies, diesel and gasoline.
11) The conversion factors used were provided by the energy producers for 2008 or 2009. Where these were not available, factors from the IEA (International Energy Agency) for 2009 were used.
12) Corrected values compared to the values shown in the Annual Report 2011
a) May include small quantities from direct renewable energy sources
b) Total water consumption not classified by source in 2010
c) Heavy metals are arsenic, cadmium, chromium, copper, lead, mercury, nickel, tin and zinc.
d) Not recorded in detail in 2010
e) May also include some quantities with energy recovery
f) Corresponds to the relevant section in GRI 3.1
Further details on data quality:
• The emission factors used for fossil fuels are based on calculations by the U.S. EPA (AP-42 from 1998) and on the IPCC Guidelines for National Greenhouse Gas Inventories (2006).
• In accordance with the GHG Protocol (2004), the factors for calculating CO2e are based on the global warming potential (time horizon: 100 years) defined in the IPCC Second Assessment Report (SAR 1995).
