Environmental Statement 2025

Mobility

Mobility has become one of the key enablers of the Commission to fulfil its duties. With the digitalisation of our ways of working and the development of soft or green mobility, the Commission will reduce the environmental impact linked to travels whilst ensuring that it continues to reach out to stakeholders, international partners, and the public.

Infographic showing mobility-related emissions reductions between 2019 and 2024, with an overall decrease of more than 40%, including a 50% reduction in staff commuting, 59% in experts’ travel, and 23% in staff professional travel.
The image is an infographic presenting progress in reducing CO₂ emissions from mobility between 2019 and 2024.
At the top, the year 2030 appears as a long-term reference point. On the left side, illustrations include a bicycle, trees, green buildings, and a mobile phone displaying a map and connection symbol, representing sustainable and digital mobility solutions. On the right side, visuals include a woman running, an electric car, solar panels, houses, trees, and a wind turbine, reinforcing themes of clean transport and renewable energy.
In the centre of the image, the text “2019–2024” is displayed alongside the statement “Mobility-related emissions reduction: more than 40%,” accompanied by a downward arrow. A high-speed train graphic appears nearby, symbolizing lower-emission travel alternatives.
To the right of the central text, three circular callouts highlight specific reductions achieved between 2019 and 2024:
50% decrease in staff commuting 59% decrease in experts’ travel 23% decrease in staff professional travel Each percentage is paired with a red downward arrow to visually indicate reduction.
At the bottom of the image, a grey airplane and grey clouds appear next to the baseline year 2019, symbolizing previous higher-emission travel patterns before the reductions were achieved.
The overall design uses green and blue tones to emphasize sustainability, with contrasting grey elements to represent past emissions levels.

Reducing emissions from professional travel

Emissions are calculated using specific factors for the different modes of travel as shown in the figure below. Air travel is particularly important, accounting for over 90% of missions emissions. Accordingly the difference between the factors for different classes of air travel are an significant when deciding how to reduce emissions. Flights in economy or premium economy class generate significantly lower emissions per kilometer than those in business class. The factors take into account both flight and upstream (or Well to Tank, or WTT) emissions - those associated with extracting the fuel and making it available for use.

* NB 1) New methodology and definition of categories since 2019, 2) Emissions factors for air travel increased by nearly 20% for travel in 2024, 3) Reporting for the first time emissions for staff at all work sites, 4) Other sites - data since 2019 only

The figure above shows a dramatic drop in professional travel emissions due to the Covid outbreak in 2020, and that continued in 2021, before a "rebound" resulting from increased staff presence at workplaces and rising mobility levels in 2022 to 2024.

The increase in 2024 (from 2023), is partly a methodological lag effect due to lower occupancy of passenger aircraft during the Covid period. This masks the efforts made by staff over this period, as can be seen in the following figure, navigate to distribution of services' staff mission emissions reductions, 2019 - 2024 on this tab, where the emissions above are compared with emissions calculated with factors fixed since 2019. Using the latter approach it is evident that there has been a reduction in travel since 2023, although reported emissions (with variable factors) have increased. Emissions factors should fall as aircraft occupancy rates increased again.

Background

Data from staff missions has been extracted from a new dashboard developed by the Paymasters Office (PMO). This uses the information encoded in the Commission's management system for professional travel (MiPS+).

Staff define the geographical parameters of their travel itineraries, identifying individual travel segments and the mode of travel for each. The conversion factors described above (and that are reviewed annually) are used to calculate the emissions based on the distance and mode of travel.

The new dashboard was used to calculate emissions back to 2019 and provides more accurate real-time output than data previously extracted from the MiPS green reporting tool; the latter already having simplified by centralising the calculation of missing emissions which had previously been processed from disparate sources.

Greening Communication objective

A core component of the Commission's 2030 emissions reduction target is to reduce staff missions emissions by 50% from 2019 to 2024. To deliver this, 50 of 51 services pledged to reduce emissions. As shown in the figure below, 16 services met or exceeded the 2019 -24 reduction target while further 13 services achieved between a 30% and 50% reduction.

Distribution of services' staff mission emissions reductions, 2019 - 2024

Other tools to assist reducing mission emissions include:

  • A new Guide to Missions (under finalisation in 2024), allowing train travel in certain circumstances when more costly than flying
  • Display of emissions by different transport modes on the missions booking tool to increase awareness of the environmental consequences of different travel choices.

Reducing emissions from professional travel

The figures mentioned below provide a detailed breakdown of modal data extracted from MiPS+. The distinction between the two figures as summarised above is as follows:

  • In the second figure below, navigate on this tab, the emission factors (obtained from DEFRA) are revised annually. They usually vary little from year to year, but the factors that are applied to 2024 travel data increased much more significantly as described above.
  • In the third figure below , navigate on this tab, the emission factors used for calculating emissions in 2019 are also applied to the following years. An additional minor adjustment is also applied to allow for the category of travel Commission's car without a driver since MiPS+ lacked a factor for the period 2019-2023. This adjustment does not affect the total missions emissions because service car emissions are accounted for using real fuel consumption. This also explains the slightly different totals for 2019 in the figures. The reported emissions reduction from 2019 to 2024 is 23% for the first table and 35% for the second. Therefore the Commission's has reduced its travel more than the calculated emissions would imply.

Emissions intensity by site

The figure below displays the carbon intensity for the sites between 2019 and 2024, based on PMO dashboard data. It is evident that Luxembourg, and JRC Karlsruhe have the lowest values (below 0,2 kgCO2e/km) which is indicative of a greater proportion of surface travel and or predominantly economy class travel by air.

Grange has the highest value as many of its staff are inspectors who travel widely from Ireland, and consequently largely by air.

Carbon intensity is a useful measure that should reduce as staff fly less (or in economy rather than business class), or convert to surface travel, particularly rail.

Reducing emissions from experts’ travel

The Commission has included in its carbon footprint emissions for expert travel (covered by the Commission's administrative budget) since 2021, extending the calculations back to 2019.

The calculations use a database describing an expert's country of origin with mode of travel assumed based on distance. In 2024 the Commission developed a more automated approach to calculate 2023 data.

A more systematic method to allocate meetings by site is under development, so currently all experts' travel emissions are allocated to Brussels. Emissions are summarised in the figure below which suggests that emissions in 2024 reduced almost by 60% the emissions from experts' travels compared to 2019.

Greener commuting options

The figure below illustrates emissions from staff commuting by site. The values from 2019 onwards have been updated, incorporating information from a staff survey conducted in 2022 to assess emissions at various sites. These were re-evaluated using the 2023 population and attendance data, along with revised emission factors. Additionally, a new commuting survey was conducted in 2024, and the results are included in this statement for 2024, using the same approach for calculation as the latest 2022 survey results.

The calculations use a Commission wide average for the number of working days according to HR data that takes into account bank holidays, sick leave, annual leave, and other absences. Prior to 2019 not all sites reported commuting emissions.

Evolution of commuting emissions, tCO2e

The Greening communication requires that the following Corporate level actions be completed:

  • Revision of the mobility policy (in progress) in relation to commuting
  • Facilitation of charging electric or hybrid vehicles at some Commission car parks.

Developing a more sustainable vehicle fleet

The Commission sites have sought to rationalise their fleets, and in recent years the total number of vehicles has been below 300. They also seek to use more vehicles with no (or lower) tailpipe emissions, and the proportion of the total vehicle fleet comprising hybrid or electrical vehicles has risen to 68%. The evolution in manufacturer tailpipe emissions is presented in the figure below, navigate to Evolution of Commission vehicle fleet characteristics in this tab.

The evolution of the overall vehicle fleet

The figure below shows that there is a long term downward trend in vehicle fleet emissions, although in 2022 there was a slight rise, probably due to the regularisation of office activities after the Covid pandemic.
