CO2 balance of EPFL

More

A detailed monitoring to understand the challenges of the campus and achieve CO2 emission reduction targets.

EPFL’s CO2 balance has been developed from a life cycle analysis established with the EPFL spin-off Quantis. The balance takes into account data from the main campus in Ecublens as well as from antennas in Valais and Neuchâtel. The data from the Geneva and Fribourg branches are not included in the balance.

Feel free to contact us for any questions or information about the calculations/assumptions used.

Electricity

The EPFL’s electricity is 100% renewable (hydraulic and solar). Consumption has been relatively stable since 2015. Efforts in terms of the energy optimization of buildings have shown a slight decreasing trend in recent years.

Gas

The gas consumed is mainly used for heating (60%) and laboratory processes (40%). Exceptionally, due to the renovation works of the campus’ Heat Pump Power Plant (CCT), the consumption of gas for heating is higher over the period 2019-2021.

Fuel oil

Fuel oil was used as a secondary heating source for the operation of the CCT in very cold temperatures. For information, with the renewal of the CCT, scheduled for 2021, oil consumption ceased in 2019. However, the part consumed during the late winter of 2018-2019 remains.

Commuting

The data are based on the mobility survey offered to employees and students. Strategies launched in 2017, such as the new parking policy, the strengthening of public transport supply and the promotion of cycling, are showing positive effects with a reduction in the number of kilometers traveled by car.

Business travels

The values are calculated from data provided by EPFL’s central travel agency. Awareness-raising measures aimed at optimizing travel (preferring the train to the plane and traveling in economy class rather than business/first) and the implementation of new tools for videoconferencing are part of the strategy to reduce CO2 emissions.

Nutrition

The CO2 impact of catering is also included in the balance sheet as it represents a significant part of the EPFL’s CO2 balance. This is now one of the priorities for action in terms of sustainability. The values are calculated according to the number of vegetarian and non-vegetarian meals consumed on campus.
