EPA to propose a curb on anti-ozone chemicals
The Environmental Protection Agency will propose a "no growth" policy on manufacture of certain chemicals seen as a threat to the earth's ozone barrier against the sun's harmful ultraviolet radiation. The agency said depletion of the ozone layer by chemical pollutants is a global problem, for which the only acceptable long-term strategy is substantial emissions reductions. But it said it would settle for a short-term strategy of "no-growth" in pollution from so- called chlorofluorcarbons, which would allow time to persuade other countries to take similar steps. The EPA is considering either mandatory controls on chlofluorcarbon uses or economic incentives to put the chemical out of production.
