Mobile firm Orange is to undertake a new programme designed to assess its environmental impact.
The company has announced a partnership with the World Wildlife Fund in which the telco will make a detailed audit of how its landline and mobile services are affecting the environment in France.
Starting later this month, Orange will begin using a five-point scoring system on each of its products and services. The company will display the scores in French retail outlets and on its website.
Categories will include CO2 emissions, use of hazardous materials, energy efficiency, use of recyclable and renewable materials, and waste reduction.
"With this environmental rating system, Orange is stating its desire for transparency in the marketing of its products," the company said in a statement.
"This initiative is an important part of a partnership signed between Orange and WWF France in March 2008 that aims to speed up the implementation of the group's environmental strategy initiated in 1996."
