Time for a Smart Taxpayer Revolution
Guest post by Lindsay Sturman, a writer living in Los Angeles with her family.
We all hate taxes, but we also want and need government services. Rather than raise taxes or cut services, there’s a Third Way that has been overlooked: tax behavior that costs the public money.
“Sin taxes,” or better yet, “Smart Taxes” create a virtuous cycle – the tax raises the price of the product, causing consumption to drop, thus reducing the costly and damaging behavior. It’s Economics 101 – if we raise the price, we’ll get less of the behavior.
It’s unusual in government to have your cake and eat it too – but “Smart Taxes” is one of those rare perfect storms.
Tobacco is a great example, because most people wish fewer of us smoked, especially children. Over a hundred studies have shown that raising the price of cigarettes causes consumption to go down. Smoking also costs taxpayers dearly in health care costs treating Medicare and Medicaid patients for lung cancer, emphysema, chronic pulmonary disease and heart disease. Economists across the political spectrum agree that a pack of cigarettes should be taxed to reflect the true cost to society of smoking so taxpayers are not subsidizing tobacco companies.
Think about it: tobacco companies put out a product that causes disease and death, they make a handsome profit, and society is stuck with a huge bill estimated to cost the U.S. $96 billion a year, according to the Campaign for Tobacco-Free Kids. Economists have a word for the damage: an “externality.” In a perfect capitalist system, the cost of the externality of lung cancer would be captured in the price of a pack of cigarettes.
Carbon combustion is another area that costs us dearly – in higher rates of diseases such as asthma, traffic crashes, tailpipe and smokestack pollution, and the potentially catastrophic effects of global warming. Why should taxpayers subsidize the corporate pollution and the detrimental effects of a product, while the polluters walk away with a huge profit? Let the polluters pay, and let the price reflect the cost.
Along with cigarette taxes, another smart tax in use for decades is alcohol taxes, which cover at least some of the cost of alcohol-related disease and accidents. Along the same lines, a tax on bullets could offset some of the societal costs of shootings – the costs to hospitals, police departments and the court and prison system; this was once a political non-starter, but there is now a growing movement calling for this change. We could also be made better off, economically and health-wise, by taxing sugar and soda consumption that contributes to the marked increase in diabetes and obesity-related diseases; the costs are staggering, with obesity alone costing America a shocking $147 billion a year.
Here are examples of Smart Tax proposals from across the political spectrum:
- Carbon tax — Carbon Tax Center puts revenue in the trillions with a substantial cut in emissions – $1.5 trillion over 8 years.
- Soda tax — 1 cent per what? tax would raise $160 billion over 10 years while motivating 8-10% decline in consumption, lowering our health care costs.
- Tobacco tax— 50 cent per pack rise could raise $80 billion in 10 years (Congressional Budget Office).
- Marijuana tax – In states where legal, could raise $90 billion in 10 years and save the same in reduced law enforcement. Net gain: $180 billion.
By taxing “bads” we can achieve the trifecta: raise money to treat the disease/damage/costs, reduce consumption and thus prevent disease/damage/costs in the first place, and make a dent in health care spending and the cost of government across the board. Not to mention avoiding the incredible suffering these diseases cause – which is the best reason to do it.
Smart Taxes do not have to be a tax increase, but rather a tax shift. For every dollar raised in carbon, alcohol, and tobacco taxes, another tax could be lowered dollar for dollar: payroll taxes, income taxes, business taxes, or sales taxes. Lowering those taxes would encourage the economic activity that we want more of but which our upside-down tax system inhibits. Republicans and Democrats alike agree that sales taxes cut down on sales and payroll taxes impede job growth.
Smart Taxes could motivate the next taxpayer revolution. Whatever our political persuasion, we as citizens need to demand that our elected officials lower taxes on “goods” and raise them on “bads.”

Presenting: An Even Better Carbon-Tax (Spreadsheet) Model
Today we unveil our enhanced carbon tax model. The link on our Home Page takes you automatically to the new version. (You may also download the model by clicking here.)
As before, the model is a compact (600 kB) Excel spreadsheet that runs on PC’s or Macs with Excel 2003 or later. Like prior versions, it splits the U.S. energy-economy into a handful of “sectors” (e.g., electricity, passenger vehicles) and, for each, generates 20-year-or-more projections of usage and per-unit carbon emissions with and without a price on carbon pollution. You can set the prices yourself — we say “prices,” plural, because you can specify both the initial price and the rate of year-to-year increase; or you can use our “out of the box” pre-set prices.
The result is a pair of emissions projections — one with the carbon price and the other without — with both referenced to the same set of anticipated changes in economic activity and energy prices. The difference between the respective projections is the emission savings (reductions) imputed to the carbon tax.
Here are the key new features (these bullet points have been updated to reflect the 2014 version of the model):
- The model is baselined to 2013 levels of economic activity and fuel use. Thus it reflects the dizzying shifts of late in electricity generation shares, from high-carbon coal (which lost six percentage points of market share from 2010) to lower-carbon gas (up four points) and zero-carbon wind (up four points).
- The model employs “official” U.S. forecasts of economic growth, general inflation, and, most importantly, of prices for electricity, natural gas and crude oil, rather than our own forecasts. (The carbon tax is layered “on top of” the official prices.)
- Explicit treatment of inflation. First, the carbon tax itself can be indexed to general inflation, or not; second, energy prices (including the carbon-tax-affected prices) are translated into the nominal (inflation-inclusive) prices in which end-users actually experience (i.e., pay) them. While this may sound complex, the model results are more rigorous (accurate) than before.
- The model has seven sectors, up from five. We’ve split our catch-all category of “Other” energy uses (other than electricity, driving and other personal ground travel, freight movement, and aviation) in two: uses fueled by natural gas, and uses fueled by petroleum products. This enables the model to more fully capture differences in gas and petroleum prices including sensitivities to carbon taxes. A “miscellaneous” category captures CO2 emissions from non-electricity-generation uses of coal; from non-energy uses of fossil fuels such as natural gas used in chemical plants, LPG (liquid petroleum gas), lubricants and naphtha; and fuels used for energy in U.S. territories (which are not included in other tabs).
- We’ve overhauled our derivation of the tax’s impact on petroleum usage. Not only was our previous method needlessly convoluted; it also over-calibrated oil’s shares of the different sectors and thus led to overstating the reductions in petroleum usage from the carbon tax-caused reductions in future energy usage. (The predicted reductions are impressive nonetheless: for the Larson bill, which we model with inflation-indexed prices of $15/tonCO2 in the first year, incremented by $12.50/ton each year, the tenth-year reductions in oil usage are 4.3 million barrels a day from 2005 levels, and 2.6 million b/d from projected oil requirements without a carbon price; for comparison, the Keystone XL pipeline is intended to deliver 0.83 million barrels a day of crude from Canadian tar sands to U.S. refineries.)
- A new spreadsheet tab, Index, has links that improve navigation among the 22 different tabs.
- Clearer graphs of CO2 reductions and petroleum savings, and a new graph of revenue generation, expressed both nationally and per-household.
- Generally improved layout and presentation.
The key result — the model’s estimate of CO2 reductions from U.S. carbon taxes — is largely unchanged from earlier versions. In the tenth year of a “Larson”-type carbon tax, with the carbon tax rates noted in the large bullet-paragraph above, projected U.S. emissions CO2 from fossil fuel combustion are 1.8-1.9 billion metric tons less than predicted without a carbon price, a 33% reduction.
A few tabs in the spreadsheet aren’t yet complete. Nevertheless, the features enumerated here constitute such a large improvement over the prior version to warrant posting it today. We invite all users of the model, old and new, to kindly:
- Update earlier findings you may have drawn from prior versions of the model, substituting results from this one.
- Walk through the model with an eye toward evaluating it for logic, rigor, presentation and functionality. Please e-mail us all suggestions and criticisms, via info@carbontax.org.
Happy modeling, and best wishes.

Waxman-Whitehouse Carbon Tax Discussion Draft: Serious Questions, Curious Answers
Guest Post by Sieren Ernst, Principal of Ethics & Environment. [See 3/23 post-script, below.]
Whether or not simplicity is a personal virtue, it’s certainly an important advantage of a carbon tax over other forms of carbon pricing. Thus, the “discussion draft” on carbon taxes released last week by a bicameral task force headed by Rep. Henry A. Waxman (D-CA) and Sen. Sheldon Whitehouse (D-RI) shows a laudable trend toward simpler, more transparent ways to price carbon pollution. Despite that encouraging trend, some aspects of the draft seem to have steered out of the way to complicate an otherwise elegant concept.
Dozens of peer-reviewed economic papers have examined the key design questions that the Waxman-Whitehouse draft asks: How high should the tax start? What should the escalation rate be? Where to use the revenue? The Waxman-Whitehouse task force offered up a menu of options and asked the public to weigh in, reality-tv style, on their favorites at cutcarbon@mail.house.gov.
It’s axiomatic to microeconomics that larger price signals produce larger responses on both the supply and demand side. One need not consult economic models to know that the impact of a low carbon price and tiny escalation rate — such as the task force’s low-end option of $15 per ton of CO2 with an escalator of 2% per year — would be minuscule. Would you modify your driving behaviors more than slightly over an increase of 15 cents per gallon of gasoline? Clearly, we need the task force’s higher-end option — $35 per ton and 8% escalator — to put a real dent in U.S. CO2 emissions, or at least to top the expected reductions from EPA regulatory proposals.
But the task force didn’t ask for input on a myriad of important design issues that needlessly clutter up the proposal. A major advantage of a carbon tax over cap-and-trade is its simplicity and crystal-clear price signal. An advantage touted by cap-and-trade supporters over a carbon tax is that the pricing mechanism is flexible. The ‘discussion draft’ seems to offer a carbon tax with cap-and-trade characteristics that isn’t especially simple nor flexible.
For starters, the bill uses a confusing and complex upstream/downstream approach, imposing the tax upstream in some instances and downstream in others. The “backgrounder” accompanying Waxman-Whitehouse proposal claims that this is “simpler” and imposes a lower reporting requirement. The background document asserts that “taxing carbon in natural gas at the point of production may be impractical, as there are over 500,000 produce natural gas wells in the United States.” But the number of natural gas wells isn’t the operative figure, insofar as a single corporate entity can control thousands of wells. Even the authors of the backgrounder seem to realize they may have picked an unwieldy point of regulation. They concede, “Applying a tax at the first point of sale would require establishing a new regime, as the federal government does not currently tax the vast majority of natural gas production.” True. Most carbon tax proposals suggest taxing natural gas “midstream” at the pipeline level because there are relatively few pipeline companies and they’re already regulated.
The Waxman-Whitehouse task force suggests that their approach would cover a larger share of the economy. But according to the Congressional Research Service, the Climate Protection Act, an upstream carbon tax proposed last month by Senators Sanders and Boxer, would cover 2,869 facilities and 85% of the greenhouse gas emissions in the economy. According to EPA, the Waxman-Whitehouse discussion draft would cover 7,000 facilities and…85% to 90% of the economy. The EPA and CRS’s methodology may differ but it seems clear enough that imposing the tax upstream would create far less administrative and regulatory burden.
The discussion draft instructs the Department of Treasury to sell polluters permits for each ton of CO2 emitted. But the proposal stresses that permits can’t be banked, borrowed, or traded. So why add the extra machinery for a permit-based system instead of a straight point-of-sale tax?
All in all, Waxman and Whitehouse’s proposal looks like an enormous stride, especially when compared to complex, opaque proposals of just a few years ago. But its choice of a permit-based system raises the question of whether their aim is to start with a carbon tax but wind up with linked cap-and-trade systems as Australia and South Africa have announced they will do. Which leads one to ask: Why not continue the trend toward simplicity with a simple, upstream carbon tax with a substantial escalator calibrated to hit long-term emissions targets?

Post Script: Coverage of Non-CO2 Greenhouse Gases (3/23/13):
In addition to taxing CO2 pollution, the Waxman-Whitehouse “discussion draft” would tax six non-CO2 greenhouse gases (GHGs): methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbon-23, perfluorinated chemicals and nitrogen triflouride at CO2-equivalent rates. According to the “backgrounder” released with the discussion draft, these non-CO2 GHGs account for about 20% of the climate damage from U.S. GHG emissions. To address that sector, the draft would apply emission fees to facilities whose emissions of those gases exceed the 25,000 ton CO2-equivalent per year threshold in EPA’s GHG reporting rule.
Those emissions total about 263.3 million tons CO2-equiv. That’s substantial: it’s roughly 4% of the 6.7 billion tons CO2-equiv of U.S. GHG emissions in 2011 and helps explain the Waxman-Whitehouse proposal’s reported coverage of 85-90% of emissions; 5% more than the 85% coverage of the Boxer-Sanders proposal that applies only to CO2 emissions.
But it’s striking that the Waxman-Whitehouse proposal would cover only 263.3 million of the 1.1 billion tons of non-CO2 GHG’s in EPA’s inventory. Given the potent climate impacts of non-CO2 greenhouse gases and reports indicating substantial fugitive methane emissions, we recommend a more comprehensive approach, either by applying the tax further upstream (where more of the emissions would be attributable to large emitters above the threshold) or by reducing the 25,000 ton CO-equiv. threshold, or both.
IMF Official Preaches Simplicity at World Bank Emissions-Trading Love-Fest
“Viva Emissions Trading!” could have been the title for the World Bank’s oddly anachronistic, “Pricing Carbon To Achieve Mitigation” event at the bank’s Washington, DC headquarters Wednesday. Fortunately, after nearly two hours of genuflection at the altar of emissions-trading, Min Zhu, Deputy Managing Director of the International Monetary Fund, took to the podium to commit the apostasy of calling for simple carbon taxes.
The opening panel featured officials from South Africa, South Korea, and China extolling “market mechanisms,” especially trading. In almost apologetic terms, the South African official described his nation’s carbon tax, assuring the audience that South Africa doesn’t intend to be left out of carbon markets. The South Korean official’s presentation indicated that the country has allocated 100% of carbon allowances in the first phase of its trading system but hopes to begin auctioning a small percentage of allowances in later phases, which will garner revenue. The Chinese official deflected a question about news reports that his country plans a carbon tax, emphasizing that China is establishing emissions trading so it can link with the European Union’s Emissions Trading Scheme (ETS). But, he said, carbon taxes are an “interesting alternative” that could play a role in the future in some sectors.
In a later panel, an EU official trotted out the oft-repeated ETS “success story” that always seems to overlook its problematic volatility followed by extreme price decline. She admitted the ETS might need “some adjustments.” Finally, after three panels of babble about linked carbon markets, offsets, monitoring, reporting, verification, etc., it was Min Zhu’s turn to deliver the closing remarks.
The IMF Deputy Managing Director struck a welcome new note, suggesting that the EU’s “collapsing carbon price” might be “cause for concern” and calling instead for a “crystal-clear, stable, credible carbon price” across sectors. Zhu recommended adding price ceilings and floors to emissions trading systems in order dampen volatility. He praised the IMF’s new compilation by Ian Parry et al., “Fiscal Policy to Mitigate Climate Change,” which emphasizes the revenue potential of simple, direct carbon taxes.
Zhu also urged policy-makers to pursue broad, inclusive carbon pricing with consistent price signals and to refrain from allocating allowances, effectively giving away revenue. Continuing his revenue theme, Zhu closed by suggesting systematic review and overhaul of national tax policies to add environmental taxes, especially carbon taxes.
Thank goodness someone near the top of global financial governance recognizes the importance of simplicity and transparency in climate policy.
