Alternative fuels in transporting goods enable Metsä Tissue to decrease CO2 emissions. After the change to low fossil fuels in 2024, approximately 40% of Metsä Tissue Scandinavia’s outbound transports are now powered by HVO or biodiesel. These biofuel transports represent a vast majority of the outbound transports that Metsä Tissue organises by itself in the region. Using these fuels, Metsä Tissue in Scandinavia can reduce emissions by up to 90% per truck transport. This is an important step in our strategy and in reaching our ambitious sustainability targets for 2030. The same change has taken place in Finland for self-organised domestic transport.
Due to doubling of the production capacity in the Swedish mill in Mariestad, the transport emissions are anticipated to decrease more slowly during the transformation period. Metsä Tissue’s Future Mill programme targets world-class environmental efficiency in tissue production, and we aim for security of supply in a local production of necessity tissue products.
