Carbon dioxide and other emissions
Climate change is high on the agenda for both Sandvik and our stakeholders. Global energy demands and environmental requirements drive development of new energy-efficient solutions with low environmental impact.
Energy consumption, climate change and emissions are therefore important aspects to consider in relation to our supply of raw materials, production and transportation. Since 2013 we purchase electricity in Europe in accordance with the European Guarantees of Origin scheme, with the aim of reducing the carbon dioxide emissions from our electricity consumption. In Europe, we follow requirements regarding energy reviews initiated by the EED (Energy Efficiency Directive) 2012/27/EU.
In addition to CO2 emissions, the Group’s emissions to the atmosphere comprise acidifying substances, particulate matter and organic substances. These emissions mainly originate from our production processes, combustion of fossil fuel and purchase of heating, transportation and electricity. Direct emissions of acidifying substances include sulfur dioxide (SO2) and nitrogen oxides (NOx). The Group’s emissions of SO2 mainly originate from the combustion of oils and coal. Emissions of NOx are mainly derived from the smelting processes in Sandviken, Hallstahammar and Svedala in Sweden, from combustion processes and, to a lesser degree, from plants for pickling and cleaning of metal surfaces.
Emissions to water mainly consist of phosphorous and nitrogen, oxygen-consuming substances and metals from pickling plants. All wastewater from processes is treated before it is released.
