Will Washington become the first state to tax greenhouse gases?

With just over a week before the Washington Legislature adjourns for the year, the question recurs: Will legislators make Washington the first state in the nation to tax greenhouse-gas emissions to fight climate change? Lurking in the background as state legislators debate a carbon tax is the threat of a citizens’ initiative on the November 2018 ballot to tax carbon emissions. In Olympia, legislation has passed three Senate committees, the latest on Wednesday. That alone is historic, said to be the first time that a carbon fee was approved by any panel of state politicians.
