Washington limits carbon pollution from largest sources

Washington state regulators unveiled an updated plan to limit greenhouse gas emissions from large polluters, the latest attempt by Gov. Jay Inslee to push ahead with a binding cap on carbon emissions after struggling to win approval from legislators. Washington would join nearly a dozen states including California that have capped carbon pollution from industrial sources. The proposed rule requires large industrial emitters to gradually reduce carbon emissions over time. The rule would cover many industries, including power plants, oil refineries, fuel distributors, pulp and paper mills and others.
