In autumn 2015, Gasum commissioned a study on the environmental impacts of the supply chain of natural gas imported to Finland from Russia. The study focused particularly on the assessment of air emissions generated in the natural gas supply chain. Viewed over the entire life cycle of natural gas, 87.5% of the greenhouse gas emissions take place in natural gas use, 12.2% in activities taking place in Russia and 0.3% in transmission carried out by Gasum in Finland.
LNG supply chain
Our LNG production facilities are located in Risavika, Norway, and Porvoo, Finland. LNG is also imported to the Nordic countries via terminals in Northwestern Europe. LNG is delivered using road tankers and carrier vessels from LNG terminals to customers. The terminals are located in Øra and Risavika, Norway, Lysekil, Sweden, and Pori, Finland.
Biogas supply chain
The raw materials used in biogas production are waste-based feedstocks such as biowaste, wastewater sludge and organic side streams from industry and, at the Swedish plants, also field biomass. Raw materials are delivered to Gasum biogas plants where they are used in the processing of biodegradable waste, biogas production and the production and distribution of recycled nutrients.
Air emissions from gas use
Natural gas is the lowest-emission fossil fuel. Substituting oil or coal with natural gas can help achieve significant emission cuts. Liquefied natural gas and biogas can be used as substitutes for more polluting petroleum-based fuels for industries outside the gas pipeline network as well as for maritime and road transport.
The combustion of natural gas, liquefied natural gas and biogas does not create any particulate or sulfur dioxide emissions.
Ecolabels awarded to biogas
Gasum biogas has been awarded the Nordic Ecolabel and Gasum road fuel biogas also the Made in Finland Key Flag Symbol.
In addition, Gasum has the Biogas Label that communicates to consumers that the product or service was made with 100% Finnish and renewable biogas. The Biogas Label is a registered trademark owned by Gasum.
