Impact de Act for Change

EPFL strives, through the Challenge Act for Change, to influence behavioural changes and thus contribute to the protection of the environment.

Concrete results

Ideas from the platform
The Act for Change platform allows participants to submit action ideas that are then, prioritized and selected by the EPFL Environment Commission and implemented with the relevant stakeholders. Two examples of ideas that have been implemented:
- the introduction of washable dishes for take-out dishes
- the recognition action for campus cleaners at the end of each year.

Engagement of participants in their structures
After participating in a Challenge Act for Change, some people commit themselves to sustainability within their departments, labs or even faculties with concrete measures. For example, following the last Challenge, several laboratories have decided to systematically plan vegetarian meals for their events, one of which is a major international conference. Another example is a petition signed by 813 people asking for the improvement of the vegan offer, proof of the progressive awakening of the community, was launched at the end of the last Challenge.

Impact of Act for Change Food 2018

The innovation of the last edition (November 2018), focused on food, was to quantify the impact of the campaign, by associating the EPFL Data Science lab for the analysis of the data available, i.e. all food purchases on campus (7 years of data available). The data collected as part of the Challenge Act for Change have been pseudonymized in order to be used for research purposes at EPFL.

In order to measure the environmental impact of the Challenge, we only measured the number of vegetarian menus sold in campus restaurants. Analysis of the impacts of the Challenge Act for Change Food shows that the impact is significant, with 28% increase in vegetarian menus during the campaign but that it remains to be confirmed over the long term. The number of actions performed per participant also increases significantly with the size of the team, seeming to confirm the hypothesis that team participation stimulates action and commitment.
