The state of Delaware, which already distinguished itself this year by approving criminal sanctions for executives at polluting companies, has now announced a voluntary program designed to give manufacturers incentives to surpass state environmental and conservation standards. The Principles for Responsible Industry program, which was announced yesterday by Gov. Ruth Ann Minner (D), sets high benchmarks for worker protection, pollution prevention, waste reduction, energy conservation, and corporate citizenship; if companies meet the targets, they can earn accelerated permit reviews, community recognition awards, and fewer inspections. Ciba Specialty Chemicals and DuPont have already signed on to the program, and Minner said she would call on all manufacturers in the state to enroll.
