Will Washington State be first in taxing greenhouse gases?

OLYMPIA – Could 2017 be the year Washington emerges as the first state to tax emissions of a greenhouse gas? Barring some unusual turn of events as legislators finalize the state budget here, don’t count on it. But that assessment comes with an asterisk. There are signs that business opposition to the idea is softening. Meanwhile, environmentalists and their allies have made it clear that if the Legislature doesn’t act this spring, they’ll bring to issue to voters next year.
