Washington Initiative 732

Washington Initiative 732 (I-732) was an initiative to create a carbon tax to the Washington State Legislature, which appeared on the November 2016 ballot. The backers of I-732 submitted roughly 350,000 signatures in December 2015 to certify the initiative.

The initiative was spearheaded by environmental economist Yoram Bauman, a strong advocate of carbon pricing. It was modeled after the British Columbia carbon tax, which was considered "popular across the political spectrum". The carbon tax in British Columbia caused the province's fuel consumption to decrease by 16% and its greenhouse gas emissions to decrease 3.5 times faster than the emissions of Canada as a whole, while maintaining steady economic growth.

On November 8, it was rejected.

The ballot measure summary as written by the Secretary of State of Washington:

"This measure would impose a carbon emission tax on the sale or use of certain fossil fuels and fossil-fuel-generated electricity, at $15 per metric ton of carbon dioxide in 2017, and increasing gradually to $100 per metric ton (2016 dollars adjusted for inflation), with more gradual phase-in for some users. It would reduce the sales tax rate by one percentage point over two years, increase a low-income sales tax exemption, and reduce certain manufacturing taxes."

Initiative 732 contained four provisions:

The primary sponsor of Initiative 732 was CarbonWA, a group founded by environmental economist Yoram Bauman to promote carbon pricing. The Audubon Society was also a major proponent of Initiative 732, "Audubon Washington believes Initiative 732 provides swift and effective action to reduce carbon pollution". Other organizations that supported Initiative 732 included the Sightline Institute, and the Citizens Climate Lobby. Other supporters include Washington State legislator Joe Fitzgibbon (D), Washington State Senator Steve Litzow (R), Washington State Senator Joe Fain (R), Washington State Senator Cyrus Habib (D), and the editorial board of The Olympian. Climate scientist James Hansen, who has been involved with the Citizens Climate Lobby for many years, strongly supported the proposal.
