Covestro has considerably reduced carbon dioxide emissions and energy consumption over the last few years. This has been achieved even though production increased significantly in the same period. The main reasons for this success are a variety of innovative, environmentally friendly production processes and the in-house development of a system for efficient energy management at our company’s large production plants.
Between 2005 and 2014, Covestro reduced specific greenhouse gas emissions at its main sites by 39 percent. This figure describes the CO2 emissions in metric tons generated during the production of one metric ton of product. In the same period, specific energy consumption was reduced by 30 percent – i.e. the amount of primary energy in terawatt hours per metric ton of product. Since the original goal of a 40 percent reduction in CO2 emissions by 2020 has nearly been achieved, Covestro set a new goal for itself in early 2016: The company now wants to half its emissions by 2025 relative to a baseline of 2005, thus demonstrating that the chemical industry is doing its part to support the targets set at the climate conference in Paris.
A new common calculation method was introduced in 2014 to ensure more transparent and consistent reporting of greenhouse gas emissions and energy efficiency as a new KPI. To determine the specific values, data from Covestro’s 17 most important sites worldwide were compiled. These sites are responsible for more than 95 percent of the company’s total emissions.
The direct and indirect emissions in CO2 equivalents (Scope 1 and Scope 2) were reported using current and site-specific emission factors in accordance with the international Greenhouse Gas Protocol. For a meaningful primary energy comparison, the procured secondary energy was converted with standard factors into primary energy and then added to the amount of primary energy consumed. The reference value for the specific indicators was the aggregated, specification-conform production volume of all production plants at the 17 sites.
