Water-quality trading can reduce river pollution: Market for water quality credits would cut pollution at less cost

23 septiembre 2014

Allowing polluters to buy, sell or trade water-quality credits will reduce pollution in rivers and estuaries faster and at lower cost than requiring them to meet compliance costs on their own, a new study finds. Establishing trading markets at a river-basin scale and allowing interstate trades will yield optimal results, but regulators shouldn’t let uncertainties over details bog down a program’s launch, since trading at any scale will yield gains over no trading at all.
