A two-year project involving nine private and public organisations from southern England and northern France has shown how reducing waste and training staff on environmental issues can save businesses money.
The Environmental Stewardship Project, part-funded by the EU and designed to improve corporate environmental performance, ends in March.
East Sussex County Council led the project. Lead cabinet member for the environment Matthew Lock said: "The project partners have all been able to cut their operating costs which means there is more money available to spend on further environmental improvements and other key services."
This has dramatically cut the amount of waste going to landfill or incineration from 18 key sites.
The partners also began strengthening environmental specifications in contracts, and earned recognition under the international environmental standard ISO 14001 for more than 40 sites.
The nine partners of the Environmental Stewardship Project were East Sussex County Council, Kent County Council, Medway Council, Région Nord Pas de Calais, Communauté Urbaine de Dunkerque, East Kent Hospitals NHS Trust, Hastings Borough Council, Global Action Plan and Business Eco Logic.
