In May 2019, I wrote in Vox that “one weird trick can help any state or city pass clean energy policy.” Spoiler: the one weird trick is electing Democrats. My home state of Washington elected a whole mess of Democrats over the last several cycles and it is paying off handsomely. Without much national attention, the last few years have seen Washington quietly put into place the most comprehensive and ambitious slate of climate and energy policies of any US state. Yes, I’m talking to you, California.The legislature just passed a carbon cap that will reduce economy-wide greenhouse gas emissions 95 percent by 2050 (it awaits Gov. Jay Inslee’s signature). I want to talk about that bill, but first, to understand its significance, we need to quickly review all the other stuff the Washington legislature has been up to lately. Let’s run through the last three years. It’s a lot. (And this is only the climate stuff; there’s much more: police reform, a capital gains tax, reduction in penalties for drug possession, etc.)In 2019, the legislature passed:the Clean Energy Transformation Act (CETA), the most significant energy bill in state history, which will require state utilities to reach carbon neutrality by 2030 and 100 percent self-generated carbon-free electricity by 2045; it also contains a bunch of sexy utility business-model reforms;the Clean Buildings bill, a first-in-the-nation program that requires large commercial building owners to address the energy efficiency of their existing buildings;a bill on hydrofluorocarbons (HFCs), which will phase out dangerous ozone-depleting (and climate-warming) aerosols, foams, and refrigerants (making Washington the second state, after California, to do so); andHB 2042, which puts about $170 million toward transportation electrification, through tax incentives for mid-market EVs, money for charging stations, and money to transit agencies to electrify buses. In 2020, it passed:SB 5811, which adopts California’s Zero-Emissions Vehicle (ZEV) program and California’s Advanced Clean Truck Rule, requiring rising sales of ZEV passenger vehicles and heavy- and medium-duty trucks, respectively; andan update of the state’s greenhouse gas emission goals: 45 percent reduction from 1990 levels by 2030, 70 percent by 2040, and 95 percent/net-zero by 2050. In 2021 so far, it has passed:HB 1050, another HFC bill that goes beyond recently adopted federal standards;HB 1084, the Healthy Homes and Clean Buildings Act, which would take a number of steps to gradually phase out natural gas utility service and boost building electrification [Correction: 1084 did not actually pass; it died in the Appropriations Committee, but several of its provisions passed via the state budget]; andHB 1091, which would establish a clean fuels standard (CFS) that gradually reduces the carbon content of liquid fuels in the state, similar to laws already in place in California, Oregon, and British Columbia (making a declining carbon standard for fuels the law of the land from the Mexican border to the Yukon). This has been a long fight in Washington — the CFS is one of Big Oil’s least-favorite policies — and this is the third attempt to pass it, so victory is sweet.So, the legislature has already passed laws specific to electricity, transportation, buildings, and fuels. All of this activity sets the context for last week’s finale: SB 5126, the Climate Commitment Act (CCA — here’s the bill text). I wrote last year that carbon pricing has been dethroned in left-leaning carbon policy circles, in favor of industrial policy — sector-specific standards, investments, and justice (SIJ). But the dream of carbon pricing never died in the hearts of Jay Inslee and Washington legislators. The CCA is a “cap-and-invest” program that would impose a declining cap on emissions and distribute allowances under the cap, thereby placing an escalating price on carbon. There’s lots to say about this, but the first thing to note is that this is not carbon pricing
