Q4 2016 had colder weather conditions compared to Q4 2015, particularly in November and December. When adjusted for this effect, CO2 emissions were 2.7 percent higher than one year previously.
Higher CO2 emissions at energy companies
In Q4 2016, CO2 emissions by energy, water and waste management companies increased by 5.5 percent on the previous year. These companies account for around 30 percent of total CO2 emissions. The rise can mainly be attributed to a year-on-year increase in electricity production at power stations, particularly as a result of increased foreign demand.
Transport sector emits more CO2
CO2 emissions by the transport sector rose by over 5 percent in Q4. This sector is responsible for nearly 14 percent of total emissions. The rise in total value added of the transport sector is less significant than the rise in CO2 emissions. Emissions by the aviation sector and inland shipping increased most notably, by nearly 9 and more than 7 percent respectively, mainly due to an increase in transport activities.
Higher CO2 emissions in agriculture and chemical industry
Emissions of CO2 in the cluster agriculture, mining, manufacturing industry and construction were up by over 2 percent relative to Q4 2015. This cluster contributes 23 percent to total emissions. The agricultural sector and the chemical industry in particular accounted for higher CO2 emissions. In the chemical industry, this was largely due to increased output.
CO2 emissions by other services and private households
In Q4 2016, CO2 emissions by other services – accounting for over 12 percent of total CO2 emissions – rose by 15 percent. This was mainly due to higher consumption of natural gas for the heating of office buildings. As for CO2 emissions by households, which account for more than 20 percent of total CO2 emissions, the increase in Q4 2016 was considerably higher (nearly 14 percent) than one year previously. Here as well, the increase is mainly the result of higher consumption of gas for heating.
The calculation of CO2 emissions is consistent with the definitions used in Environmental accounts. This is a first estimate.
