The BC recipe for carbon pricing looks something like this: Take a carbon tax and mix it with corporate and personal income tax reductions; keep it simple; slowly shift the tax burden from income to carbon pollution over time.

Is Oregon the next place this dish will show up on the menu? Governor Kitzhaber is running for re-election on a platform that prominently includes tax reform. “It’s got to be on the agenda,” he told state business and labor leaders, “and it’s my intention to put it squarely on the table.” Kitzhaber has not yet committed to proposing a carbon tax, but he’s considering it.

Last year, the legislature in Salem passed a study bill specifically focused on “the feasibility of imposing [a fee or tax on greenhouse gas emissions] as a new revenue option that would augment or replace portions of existing revenues.”

The study itself will not be completed until November, but the state has awarded the contract to Northwest Economic Research Center (NERC), headed by Portland State University economics department chair Tom Potiowsky, who previously spent a decade as the Oregon state economist. NERC has already conducted a preliminary report on carbon pricing in Oregon.

The key takeaway from that report was that environmental tax reform can benefit the economy and reduce emissions. “The report shows that putting a price on carbon in Oregon can result in reductions in harmful emissions and have positive impacts on the economy,” it says. Elsewhere, it notes, “[A] BC-style carbon tax and shift could generate a significant amount of revenue and reduce tax distortions while creating new jobs and reducing carbon emissions. The specifics of the tax shift program are key to ensure equitable distribution of costs and benefits, as well as preserve the strength of the price signal.”

Here are some targets to keep an eye on as the state moves forward:

Carbon tax rate

The BC carbon tax started at $10 per ton of CO2 and went up by $5 per ton per year until 2012, when it stabilized at $30. Oregon should at a minimum aim to catch up with BC, and ideally Oregon would enhance revenue stability by indexing the top rate to something like state GDP growth plus 2 percent. (The extra 2 percent would account for and promote carbon reductions.) A tax that rises to $60 would go a long way toward returning Oregon’s emissions to 1990 levels, according to NERC’s projections (see chart). (UPDATE, 4/4/2014: For clarification, the chart shows projections assuming a carbon tax that starts at $10/ton and rises by $10 per year until it reaches $60 per ton.)

Carbon tax coverage

Like BC, Oregon would do well to cover all fossil fuels burned in the state. In fact, Oregon could best British Columbia by taxing imported electricity based on the carbon pollution its generation entails. Oregon imports a lot of fossil-fuel-fired electricity from outside of the state; accounting for so-called “carbon by wire” more than doubles the carbon footprint associated with electricity use in Oregon. If you ignore carbon by wire, electric power plants emit about one-fifth of the state’s total carbon pollution; if you include it, the electric sector accounts for almost one-third of the total. The state could also leapfrog British Columbia by taxing the carbon used in airplanes (and perhaps ships) that travel outside the state. Like the province, Oregon can keep exemptions minimal, to ensure fairness and simplicity.

Revenue recycling

NERC estimates that a BC-style carbon tax of $30 per ton of CO2 would generate about $1.2 billion a year, or about 8 percent of the state’s annual General Fund revenue. Taxing carbon-by-wire and jet fuel carbon pollution would boost those numbers to around $1.4 billion and 10 percent. What happens with that revenue is key to the economic and political viability of a carbon tax proposal. (It’s perhaps worth noting that a carbon cap with similarly broad coverage and auctioned permits could generate comparable revenue. The two options are far more similar than many partisans of one or the other care to recognize.)

  • A revenue-neutral approach—one that devotes 100 percent of the revenue to reducing existing taxes, as in British Columbia—is attractive both for its potential bipartisan appeal and its simplicity. It would also put a political ratchet on the carbon tax: backsliding would be difficult because reversing a carbon tax shift would require raising income tax rates, or other tax rates, that carbon revenue had replaced.

    Arguments for dispensing with revenue neutrality also have merit. One of the recommended NERC scenarios, for example, devotes 50 percent of the revenue to corporate income tax cuts, 25 percent to personal income tax cuts, and 25 percent to targeted reinvestments in home energy efficiency, industrial energy efficiency, and transportation infrastructure. Oregon schools are also famously starved for funding, so perhaps a share of carbon tax funds could go to the education budget. These options sounds easy, but the devil is in the details. What if “transportation infrastructure” includes urban highway megaprojects?

    Impacts on low-income households

    A glance at household energy expenditures for different income quintiles (see figure) shows the importance of addressing impacts on low-income households. Low-income Oregonians devote more than five times as much of their money to energy bills as do the richest Oregonians.

    NERC notes that “careful program design can also offset the potential extra burden on low-income households,” which is certainly true. Figuring out good ways to do it is a challenge, though. Some options include boosting the state’s Earned Income Tax Credit (currently a meager 6 percent of the federal EITC) or otherwise working through the state’s income tax, providing additional funding for the state’s Low Income Home Energy Assistance Program, attempting to mirror the efforts of programs like Efficiency Maine, or providing a simple dividend to low-income households. (Everything Sightline has written about making cap-and-trade fair for working families applies to carbon taxes, too.)

    Impacts on manufacturers and agriculture

    Most businesses will hardly notice a carbon tax swap, especially if corporate income tax reductions are part of the package. But energy-intensive businesses (see the list in this paper) might need special attention, especially if they sell into national or global markets and so will be competing with other companies who won’t have to pay the carbon tax. These sectors might be targets for corporate tax relief. The forthcoming NERC study will, we hope, use both case studies and an economy-wide analysis to highlight whether and how a carbon tax could work for these sectors.

    Geographic disparities

    Northwest politics often divide between the areas west and east of the Cascades, but electricity politics are an order of magnitude more complicated. The map below shows how utility service zones in Portland and surrounding areas are fragmented between public entities (in tan, green, and yellow, representing Public Utility Districts, co-ops, and municipalities, respectively) and Investor-Owned Utilities (IOUs) such as Portland General Electric (orange lines) and Pacific Power (purple stripes). The whole state is similarly balkanized.

    This utility map shapes electricity politics, because different providers cast different carbon shadows. About 30 percent of the electricity in Oregon flows to consumers from Tillamook PUD and other consumer-owned utilities that draw their kilowatts mostly from the Bonneville Power Administration. BPA markets electricity from federal dams and from a nuclear plant on the Hanford Reservation in central Washington. These utilities will not feel much heat from a carbon tax. The rest of the electricity comes from IOUs such as Portland General Electric, which serves 800,000 customers in and around Salem and Portland, and Pacific Power, which serves 550,000 customers, including those in parts of Portland and in some or all of Bend, Medford, and Pendleton. Electricity from these IOUs is much more carbon-intensive, so a carbon tax will hit their customers much harder, especially if it applies to imported electricity. Pacific Power, for example, generates about 65 percent of its juice by burning coal at plants spread across ten Western states.

    A tasty challenge

    Overall, Oregon is positioned to follow BC’s lead in putting a price on carbon. Yes, there are challenges, most of which British Columbia encountered as well. There’s also opportunity. The preliminary NERC report shows how a carbon tax might be just the recipe Oregon needs: it could provide tax reform and climate solutions in a single dish.


    This Thursday, April 3, see Yoram discuss carbon pricing in greater depth as part of a panel at Portland State University’s Institute for Economics and the Environment. Should Oregon Lead on Carbon Taxes? will be held at the Market Center Building, Room 123, and is open to the public. More info is available here.
