In 2020, we managed to reduce emissions from our own operations by 21% (tCO2e/revenue in EUR million). The reduction in emissions was mainly due to the increase in renewable electricity in our production and offices in Finland and Norway. In addition, business flights taken by personnel also decreased due to the coronavirus pandemic.
For materials for self-developed projects, emissions remained almost at the level of the comparison year. In 2020, we focused on increasing our understanding of carbon footprint calculations and the factors that affect our carbon footprint. Among other things, we studied different material alternatives and commissioned several theses on the emissions produced by different materials. In 2020, we also started the construction of two modular wooden apartment buildings in Tampere.
The theses and the carbon footprint calculations have shown that different concrete products are the largest source of emissions due to both their emission factors and quantities. Reducing the emission impact of these products will be particularly important in achieving the emission reduction target of the projects. Steels and reinforcements are the next largest source of emissions – depending on the design solutions of the project – as well as different types of insulation and, for example, plaster boards. This is especially true of apartment buildings with concrete frames, of which we have the most calculation results. In other types of projects, the ratios of the emission effects of materials may differ. For example, in a heavier industrial building, there may be proportionally more structural steel, while in a timber-framed apartment building, the effect of other materials is accentuated with a smaller carbon footprint per unit volume of wood products.
In autumn 2020, we launched group-wide road map work to promote emission reductions in the coming years. The road map will be updated regularly and will guide our work to reduce emissions.
