Oil companies, including BP and Koch Industries, have continued to pour money into the campaign against I-1631. As of October 22, oil and fossil fuel companies had contributed more than $25 million to the industry PAC opposing I-1631, the initiative that would create a carbon tax and spend the receipts on renewable energy and climate change mitigation. Most of that money—$25,179,028.93, to be exact—has come from out of state companies. Washington fossil fuel companies have contributed $561,031.31, or about 2 percent of the fossil fuel industry’s spending on the race.

The largest out-of-state contributors to the No on I-1631 campaign are:

BP America, $9,596,031.40

Phillips 66, $7,201,186.54

Andeavor, $4,362,827.17

American Fuel and Petrochemical Manufacturers, $1,000,000.00

Valero, $995,000.00

Koch Industries, $550,000.00

Chevron, $500,000.00

The No campaign has also drawn support from the in-state agriculture (potato and fruit grower PACs) and concrete industries.

Meanwhile, the Yes campaign has raised $13 million, and its message prominently mentions oil companies’ spending.

The Yes campaign’s leading donors are:

The Nature Conservancy, $1,550,000.00

League of Conservation Voters, $1,400,000.00

Bill Gates, $1,000,000.00

Michael Bloomberg, $1,000,000.00

Chris Stolte, $500,000.00

Sarah Merner, $500,000.00

Action Now Initiative LLC, $500,000.00

Craig McKibben, $500,000.00

The Yes campaign has (unsurprisingly) drawn the support of most of the state’s environmental groups. The Washington State Labor Council, the state branch of the AFL-CIO, also kicked in $125,000.00. Microsoft contributed $50,000.00.
