Other measures, including market-based instruments and other standard setting measures, might be more cost-effective in producing more rapid eco-innovation. Such agreements include quantitative targets and timelines concerning, for instance, control of greenhouse gas emissions, the reduction, reuse and recycling of w'aste, and reduced use of hazardous chemicals in manufacturing. Businesses consider voluntary initiatives and corporate environmental management as ways to reduce further government regulation and strengthen their ability to compete on the global market.
