Investment in resource-wise bioenergy decreases fossil CO2 emissions, improves energy efficiency and increases the share of production made with renewables. These are the Group’s main means in combatting climate change.
At the end of 2011, Metsä Group introduced a Group-wide target for reducing fossil carbon dioxide emissions in production by 30% per product tonne from 2009 level. Thanks to the bioenergy investments to Metsä Wood Lohja, Metsä Fibre Joutseno and Metsä Board Kyro mills during 2012, we were able to achieve the target already in 2013. Since then we have been able to surpass this target; in 2016, the reduction of fossil CO2 emissions was 35%.
Use of renewable energy in production is the main reason for lesser CO2 emissions. For example in 2011, wood-based bioenergy accounted for 63% of the Group’s production, but today 86% of the production is made with biobased fuels. 23 of our 35 production units have bioboilers and bioenergy production on site, and in Metsä Group the renewable energy is mainly made out of production side streams.
Combatting climate change at the mills
Metsä Group is continuously investing in the best available technology. As part of the investment we aim to increase the share of bioenergy in production. Read below examples from our business areas.
Metsä Fibre’s pulp mills generate a lot of renewable energy with energy self-sufficiency levels of 140%. This level will increase when the Äänekoski bioproduct mill starts up. The bioproduct mill will also operate with zero fossil energy or emissions.
In 2012, when Metsä Board’s Kyro mill’s biopower plant started, it halved the carbon footprint of the paperboards manufactured at the mill. CO2 emissions from the Kyro mill reduced by approximately 100,000 tonnes, to about a quarter of previous levels. The new pulp turbine at Husum mill was installed in 2011 increasing energy production.
The biopower plant at Metsä Wood’s Lohja mill was inaugurated in January 2013. The plant produces heat to the Lohja district and process steam to the Kerto mill. It has decreased CO2 emissions by about 40,000 tonnes.
Metsä Tissue has ongoing investments: In the autumn of 2017 the Nyboholm and Mänttä mills will have increased biobased energy production at the sites. In 2015 the start-up of the bioboiler at Katrinefors mill reduced the use of fossil oil by 90% equalling to 6,000 tonnes of fossil CO2 emissions.
