The weather was colder in Q3 2017 compared to the same quarter last year. September in particular was much less warm. When adjusted for this effect, CO2 emissions were 1.2 percent lower in Q3 than one year previously.
Higher CO2 emissions by households and services sector
CO2 emissions by households were up by over 5 percent in Q3, mainly due to higher consumption of natural gas for the heating of homes. Motor fuel consumption also increased. CO2 emissions by households amounted to over 15 percent of total CO2 emissions.
In Q3 2017, the level of CO2 emissions by the services sector – accounting for 10 percent of total CO2 emissions – was up by over 8 percent year-on-year. In the services sector as well, consumption of natural gas increased, in this case for the heating of commercial buildings.
Higher CO2 emissions in agriculture and manufacturing
Emissions of CO2 in the cluster agriculture, mining, manufacturing industry and construction were up by more than 4 percent in Q3 year-on-year. This cluster contributes more than one-quarter to total emissions. By contrast, emissions in the petroleum industry dropped significantly.
Transport sector emits more CO2
CO2 emissions by the transport sector rose by nearly 3 percent in Q3. This sector is responsible for nearly 18 percent of total emissions. The sharpest increase was seen in goods transport by road, mainly due to more transport activities.
Reduced CO2 emissions by energy companies
In Q3 2017, CO2 emissions by energy, water and waste management companies went down by over 8 percent year-on-year. These companies account for over 31 percent of total CO2 emissions. The reduction can mainly be attributed to a year-on-year decrease in electricity production by energy companies. Exports of electricity in particular declined.
The calculation of CO2 emissions is consistent with the definitions used in Environmental accounts. This is a first estimate.
