Greenhouse Gas Emissions and Economic Activity in the Information & Communications Sector

Figure 6.1 shows trends in territorial greenhouse gas emissions, gross value added at constant (2023) prices, and employment numbers for the Information & Communications sector from 2011 to 2023. Compared with 2011, in 2023 GVA had risen by 438%, employment was up 95%, and emissions had increased by 237%. Emissions from fossil fuels used to generate electricity were assigned to the final consumer in this release.

Figure 6.2 shows the Information & Communications sector share of total emissions, GVA, and employment. In 2023, emissions from the sector were 3% of total greenhouse gas emissions, compared with 1% in 2011. The share of GVA went from 9% in 2011 to 20% in 2023. The employment share was 5% in 2011 and 6.5% in 2023.

Table 6.1 shows data on levels of greenhouse gas emissions, GVA, and employment numbers for the Information & Communications sector from 2011 to 2023, as well as the share of total emissions, GVA and employment. In 2023, emissions were 1.8 million tonnes of carbon dioxide equivalent (down from 2.1 million in 2022), GVA was €101 billion (up from €90 billion in constant prices in 2022), and employment in the sector was around 174,588 persons (up from 168,401 in 2022).

Sources of Greenhouse Gas Emissions

Figure 6.3 shows sources of greenhouse gas emissions in the Information & Communications sector in 2023. Emissions from fossil fuels used to generate electricity were assigned to the final consumer in this release. Electricity consumption was the source of 97% of emissions in 2023, up from 88% in 2011. Table 6.2 shows the share of the main emissions sources each year from 2011 to 2023.
