"Carbon pricing will be on the ballot in Washington state in November, and the money is pouring in from big-name environmental groups backing the initiative and oil companies hoping to kill it.
The ballot measure, Initiative 1631, would impose a $15 fee on each metric ton of carbon dioxide beginning in 2020 and increase $2 annually until the state reaches its emissions goals.
Supporters, including a wide range of environmental and labor organizations, view it as potentially historic and a much better option than the revenue-neutral carbon pricing ballot measure that failed in Washington in 2016.
But they find themselves up against an old foe. Two opposition campaign groups are funded almost entirely by the oil and gas industry, according to state disclosure forms."
