Impact of Standardised Management Systems on Companies' Environmental Performance. The Case of Algerian Companies Certified to ISO 14001/2015

Businesses make a significant contribution to development and quality of life through the creation of wealth, jobs and added value, but not without consequences for theenvironment. Voices were immediately raised to curb the perverse effects of this development. To this end, the World Standards Organisation (ISO) has launched the international standard ISO 14001 "environmental management" to provide a reference framework for the implementation of environmental management. A number of studies have been carried out around the world to assess the impact of the implementation of this standard on business performance, but very few have been carried out in developing countries, such as Algeria. This contribution therefore aims to enrich thedebate on this issue. In this paper, we present the results of empirical research carried out on a sample of Algerian companies certified to the ISO 14001/2015 standard. Overall, the results show that this impact is effective in terms of controlling environmental aspects, but remains questionable when it comes to companies' economic imperatives.
