The state of climate change today makes the green shift more urgent than ever. The STM has a key role to play in that transition, both by delivering sustainable mobility and by setting sustainable development objectives.

Our fourth sustainable development plan is built on a strong foundation that will allow us to go even further.


Our commitment to sustainable development is sincere and steadfast across our organization. That’s why sustainability is one of the three driving forces of our 2030 Strategic Organizational Plan. Our ambition is to ensure that all our actions and decisions are made with consideration for their impact on human life, the planet, and economic sustainability.


We know we can count on our staff and partners to help us carry out this ambitious plan and strengthen our position as a leader in sustainable development.
