Change is sustainable

The group


Our motto "change is sustainable" reflects the transition of the companies, our territories, our cities and our rural areas towards a sustainable society. This goal involves the ability to master the innovative and low-carbon technologies developed by many SMBs (Small and Medium Size businesses). The role of Envirogroup in this transition is to provide pragmatic solutions by offering a shared offer of inclusive engineering.
Sustainable companies, important planners and international donors are willing to innovate for the development of low-carbon sites, but they are often limited by the ability to identify solutions and make them work together. Therefore, there is a real expectation of comprehensive responses.
Envirogroup's engineers and experts in our subsidiaries and undeclared partnerships now cover all fields allowing to anticipate and facilitate both public and private customer's transition to low carbon economies.
Our ambition is to increase visibility of our offer nationally and internationally.
