Greenhouse gas emissions


In 2018, the greenhouse gas emissions of the metropolitan area were, according to the preliminary estimations, altogether
 4 770 thousand tonnes of CO2e. This equals to 4.1 tonnes per capita.

Greenhouse gas emissions of the Helsinki Metropolitan Area were reduced by 4 per cent in 2018

According to the emission assessment by HSY, 4.8 million tonnes of greenhouse gas emissions were generated in the Helsinki Metropolitan Area in 2018. Emissions were reduced by 4 per cent compared to the year before. In 2018, emissions from electricity use, district heating and waste treatment were reduced. 

According to estimates from the Helsinki Region Environmental Services (HSY), the climate emissions in the Helsinki Metropolitan Area were reduced by four per cent in 2018 from the previous year. The combined climate emissions, generated by the cities in the Helsinki Metropolitan Area, were equivalent to 4.8 million tonnes of carbon dioxide in 2018, which means 4.1 tonnes per resident of the Helsinki Metropolitan Area. Greenhouse gas emissions were reduced by five per cent in Kauniainen, and by four per cent in Espoo, Helsinki and in Vantaa. In comparison to 1990, the total emissions were reduced by 16%. 

Emissions generated by electricity consumption and district heating in particular were reduced. Greenhouse gas emissions generated by waste treatment remained at nearly the same level as in the previous year. In district heating production, the use of coal decreased in all cities in comparison to the year before. In turn, the use of natural gas was increased, which is the main reason for greenhouse gas emission reduction in district heating. The share of renewables in heating production continued to grow, but only by one per cent. Emissions from electricity consumption were reduced by seven per cent. The reduction in emission is related to the fact, that electric energy consumed in Finland and in the metropolitan area is more low on emissions compared to early 2010s especially due to the increase in electricity import and renewable power and reduction in coal-based condensing electricity production subsequent to that increase.

Transport is the second largest emission source after district heating in the Helsinki Metropolitan Area. In 2018, 29 % the total emissions were transport-related. Transport emissions remained at the same level as in the previous year.
