Carbon Footprint

Assessment and Transparency

Our annual carbon footprint is a key tool for measuring and reducing our environmental impact. It helps us identify our main sources of greenhouse gas emissions and take concrete action to reduce them.

We are committed to transparent environmental reporting and recognize its essential role in driving sustainable progress. Each year, we report our performance to the Carbon Disclosure Project (CDP, Score B), reinforcing our commitment to continuous improvement and accountability.

SBTi

Science-based climate commitment

Our climate strategy is aligned with the Science Based Targets initiative (SBTi), ensuring that our emission reduction trajectory is consistent with the goals of the Paris Agreement.
Our near-term targets are to reduce absolute scope 1&2 emissions by 54.6% and scope 3 emissions in physical intensity (purchased goods and services, capital goods, fuel- and energy-related activities, business travel and employee commuting) by 61.1% by 2033 from a 2023 base year.

By relying on science-based near-term targets, we structure our actions around measurable impact and long-term credibility.

Energy & operations

Rethinking how we consume energy

We are transforming the way we operate by progressively reducing our energy footprint and transitioning toward renewable electricity across all our offices. This transition is built on a clear roadmap, combining efficiency improvements with a long-term commitment to cleaner energy sources. Our ambition is to reach fully renewable electricity across our operations while continuously improving the performance of our workplaces.

Mobility represents a major part of our environmental impact. We are reshaping the way we travel by encouraging more sustainable alternatives and reducing reliance on high-emission transport.

This includes prioritizing train over short-haul flights whenever possible, promoting responsible commuting, and progressively transitioning toward low-emission company cars.

At the same time, we support our employees with accessible and flexible mobility options that make low-carbon choices easier in everyday life.
