Delegates and observers said varying positions on the utility of global C&I illustrate the different, sometimes contradictory objectives to which C&I might be applied. They said different countries may take similar positions for or against global C&I in pursuit of opposing goals. Some saw global C&I as necessary to achieve sustainability. Others said support for global standards aims to establish weak measures that would not prevent unsustainable practices. Still others think of C&I as a means to facilitate trade by providing a basis for common certification schemes. National C&I also provoked a range of characterizations, from a necessary protection of sovereignty to a vehicle for country-driven sustainability to an escape from global accountability.
