Acting to preserve and restore natural environments

The construction sector can play a key role in protecting and revitalising biodiversity. Beyond taking practical measures to preserve biodiversity and limit its operations’ impact on ecosystems, 51³Ô¹Ï is leveraging its expertise to make cities greener and repair natural areas.

Ecological engineering, in other words, is now an established field of expertise at 51³Ô¹Ï. It for example enables us to protect or regenerate land and water ecosystems on our public works projects.

“We now integrate regreening measures – for instance restoring wetlands or opening up ecological corridors – into many of our projects, starting at the design phase.”

Showcasing our ecological engineering expertise

51³Ô¹Ï opened an eco-demonstrator, Agrinature, near Paris in 2024 to showcase the array of ecological engineering solutions it is using on its projects (ponds, hedges, hibernation habitats, conservation agriculture, green grazing, orchards, observation stations, wetlands, drylands, etc.). Agrinature also aims to heighten awareness of the issues revolving around biodiversity among customers, partners, employees, environmental activists and anyone else interested in nature.
