Colas’ pledges

Colas’ efforts to be environmentally and socially responsible are founded on a belief that is two-fold: its activities should meet essential needs and expectations, and also be carried out in a way that is respectful of our planet and society. 

Colas is aware of the environmental challenges of its activities and therefore continuously strives to reduce its carbon footprint. It has set itself a target to reduce its direct greenhouse gas emissions (scopes 1 and 2) by 46.5% by 2030 and the emissions of its upstream value chain by 30% compared to 2019. 

Colas’ eight CSR pledges contained within its ACT (Act and Commit Together) initiative aim to address the expectations of clients, employees, partners, investors and users, as well of those of wider society. 

Colas draws on its innovative thinking and R&D to carve out and suggest ideas for infrastructure that is both useful to users and environmentally-friendly.
