Emissions from buildings and homes

This indicator gives a picture of CO2 and particulate matter emissions caused by buildings. Emissions during both the construction and use phase are taken into account here.

8,360 kt CO₂-eq.

  • In 2019, total building emissions during the construction phase totalled 8.36 million tonnes of CO2 equivalents and 17,170 tonnes of particulate matter equivalents.
  • In 2018, emissions from the heating of buildings amounted to 14.29 million tonnes of CO2 equivalents and 9,929 tonnes of particulate matter equivalents. In both cases, this is a decrease compared to 2016 and 2017.

What do we see?

The figure below gives an overview of emissions during the construction phase of new buildings in 2019 in Flanders. Emissions in this phase are the result of material consumption. As the figures indicate, non-residential buildings are responsible for the biggest share of the emissions during this phase.



The figure below represents emissions from the heating of buildings. It is clear to see that residential buildings are the biggest source of emissions here. Particulate matter emissions are in fact responsible for 99% of all particulate matter pollution. This is because 600,000 homes use wood, without filters installed in the chimney, as their primary or secondary source of heating.



What’s the aim? 

In a circular economy, we want to keep material consumption and emissions to a minimum. To achieve this goal we will have to use materials and energy sources more efficiently during both the construction and the use phase. 

What does this indicator measure?

This indicator shows the emissions from buildings in the construction phase and in the use phase as a result of heating. The numbers for the construction phase are an estimation from Gabi software.
