Migros, a Swiss chain of supermarkets, in partnership with the Swiss Secretariat for Environmental Protection, developed a software that carries out a comparative analysis of various types of containers regarding each phase of its production, utilization and final disposition. This program quantifies and sets grades for each energy unit consumed, for each kilogram of pollutant emissions, for each kilogram of water used, for each kilogram of solid waste produced etc. Instead of only offering a line of "green products", this supermarket chain intends to sell just environment-friendly products, properly labeled as such after being subjected to and approved by the software
