Datwyler has been recording the energy consumption and greenhouse gas emissions caused by its own operations for many years. The results of the last five years are shown in the accompanying table.
The five-year track record reveals an increase in energy consumption mainly resulting from business growth, new plants and acquisitions. In 2019, Datwyler in Italy invested CHF 1.7 Mio in a cogeneration plant, a combined heat and power unit with a capacity of 1.2 MW that generates electricity for heating and production processes. This new plant has a significantly higher overall energy efficiency. While lowering the need to buy externally produced electricity considerably, the system change has increased gas consumption, which is reflected in the 2020 energy balance compared to 2019. To further reduce carbon emissions at this site, green electricity is purchased since beginning of 2021. The new plant reduces operational risks, such as reliance on the grid and energy volatility, by providing a stable supply of electricity and heat.
In 2020, Datwyler’s operations were responsible for emissions of about 80’000 tons CO₂eq (scope 1 and 2)—a successful reduction in absolute CO₂ emissions by 10% compared to 2019. Thanks to the measures implemented to improve energy efficiency, relative CO₂ emissions have decreased by almost 5% compared to revenue over the past five years. The plants in Schattdorf and Sao Leopoldo have been using renewable electricity since 2012 and 2016, respectively. In 2020, two plants, Alken and Vandalia, transitioned to renewable electricity, which significantly reduced overall carbon emissions compared to 2019. In 2021, Datwyler plans to transition no less than four more plants to renewable electricity. Thus, by year-end, 40% of Datwyler’s total electricity consumption (base year 2020) at all plants will be from renewable energy sources.
