low-income people advocating for a just transition. It was also supported by Carbon Washington, the organization that had put Initiative 732 on the ballot. Other organizations that supported the initiative included Stand.earth, The Nature Conservancy, and local chapters of 350.org and the Sierra Club. Elected officials who supported this initiative included United States Representative Pramila Jayapal and Washington Governor Jay Inslee. Opposition The "No on 1631" campaign was sponsored by the Western States Petroleum Association. The American Fuel and Petrochemical Manufacturers and its members spent over $30 million to defeat the measure. Companies that funded the campaign against the initiative included Cascade Natural Gas, BP, Royal Dutch Shell, Chevron, and Phillips 66. Atmospheric sciences professor Cliff Mass opposed the initiative. Others opposed the measure because section 9(c) specifically exempted "Fossil fuels directly or eventually supplied to a light and power business for purposes of generating electricity" from the carbon tax. This meant that coal, gas, and diesel power plants would not directly be responsible for paying the carbon tax. However the majority of electricity generation in Washington state is derived from renewable sources. A 2017 report by The Washington Post indicated that 68% of electricity generated in Washington state comes from hydropower and 7% is from wind turbines. The same analysis further indicated that only 4% of Washington's energy comes from burning coal, all of which is generated by the Centralia Power Plant. This plant will begin phasing out its two coal boilers beginning in the year 2020 and transition completely to natural gas by the year 2025. Natural gas currently accounts for only 10% of Washington's energy generation, according to the Washington Post analysis. Ultimately, the initiative did not pass during the 2018 November election.
