“By correcting a well-known market failure, a carbon tax will send a powerful price signal that harnesses the invisible hand of the marketplace to steer economic actors towards a low-carbon future.”

“I am convinced that conservatives and moderates, including many Democrats, can agree on a commonsense set of policies. They would be based on responsible economic principles of free-market capitalism and personal choice, not coercion. … (The carbon emissions-reduction plan in my state of Ohio) is just one example of a national climate change response that could win support from elected leaders with a broad range of political convictions. They can start with a carbon tax or a cap and trade program, which is a market-based trading system to incentivize carbon reduction. These approaches have already shown they can work.”

USA Today op-ed, Mar. 11, 2019


"The solution isn't complicated, it's not rocket science…Emissions aren't going to go down if the cost of fossil fuels isn't honest. Economists are very clear on this. We need a steadily increasing fee that is then distributed to the public."

“We have held the view that a revenue-neutral carbon tax is the best option. (It) could be a workable policy framework for countries around the world. They can tailor it to their own economic conditions."

“What we and a number of our colleagues believe is that a better way to price the externality of carbon and create a more level playing field is to pass a comprehensive and transparent national revenue-neutral carbon tax (RNCT) that would displace much of the existing energy and environmental regulatory maze."

“To say that this issue [climate change] has sides is about as productive as saying the Earth is flat.”

“A federal price on carbon should be one part of a comprehensive response by the federal government to the threat of climate change. The proceeds should be paid out as a dividend in a progressive way that ensures that our climate policies are also reducing inequality and not burdening everyday families.”

 President Ronald Reagan

Remarks on signing annual report of the Council on Environmental Quality, July 11, 1984


“The best way to curb carbon emissions is to put a price on carbon. The cap-and-trade system President Obama advocates is one way to do that. A more direct and less bureaucratic way is to tax carbon. When polled, economists overwhelmingly support the idea.”

 N. Gregory Mankiw

Harvard economics professor, former chairman of the Council of Economic Advisers (under George W. Bush)

The New York Times, op-ed, Sept. 4, 2015


“An economy-wide price on carbon is the best way to use the power of the market to achieve carbon reduction goals, in a simple, coherent and efficient manner. We desire to do this at the least cost to the economy and households. Markets will also spur innovation, and create and preserve quality jobs in a growing low-carbon economy.”

“A carbon fee is the way economists of all stripes say we should end the massive subsidy to the fossil fuel industry and reduce carbon pollution. Our bill would harness the power of markets to ensure carbon polluters pay for the harm of their products, and then return the revenue directly to the American people. That would mean a win for our environment, a win for our economy, and a win for American families.”

 Sen. Sheldon Whitehouse (D-RI)

Press release on introduction of The American Opportunity Carbon Fee Act

“We need to impose a tax on the thing we want less of (carbon dioxide) and reduce taxes on the things we want more of (income and jobs). A carbon tax would attach the national security and environmental costs to carbon-based fuels like oil, causing the market to recognize the price of these negative externalities. [B]oth Democrats and Republicans could support a carbon tax offset by a payroll or income tax cut.”

“I believe that technology is the vital solution to fixing the problems of climate change. Businesspeople don’t innovate because it feels good; they innovate because there’s a return to that innovation. If you want a return to that innovation, you will have to price it – you will need to put a price on carbon, which means having, either through a cap-and-trade system or an explicit tax, some incentive to innovate carbon-saving technology.”

“A more efficient method of limiting global warming than regulatory controls such as proposed by the President (and that as described promise to be a bureaucratic nightmare) would be a tax on carbon emissions, which I advocated in my 2005 book and which a number of countries have adopted.”

“A carbon tax, starting small and escalating to a significant level on a legislated schedule, would do the trick. I would make it revenue-neutral, returning all net funds generated to the taxpayers so that no fiscal drag results and the revenue would not be available for politicians to spend on pet projects.”

 George P. Shultz

“Price carbon to save the planet if that pleases you; price carbon to permit growth-enhancing reforms to our tax code if that pleases you; price carbon both to save the planet and to reform the tax structure, if that is your pleasure. But price it.”

“DSM North America has long recognized that pricing carbon and strengthening the economy are not mutually exclusive. That is why we adopted our own internal price on carbon to help us do our part to tackle climate change. However, we can’t do it alone. We also need Congress to pass comprehensive climate legislation that includes a strong price on carbon—which we understand to be the best way to help businesses both reduce our carbon footprint and spur continued economic growth.”

“Climate change is a global issue that requires a global solution. The Mining Association of Canada and its members offer the following principles for consideration: 1) Establish a broad-based carbon price. 2) Apply any climate change policy-related revenues to manage the transition toward a lower carbon future, including climate adaptation…”

 “We’re going to have to have a carbon tax…. And, by the way, there are ways to do it that most Americans would be better off fiscally, because we could return it right back to the American people, but in so doing would help capture the true cost of things that are happening right now, because it’s in your and my lifetime that that cost is going to be paid one way or the other.”

 Pete Buttigieg

“I’m proud to be a cosponsor of the Energy Innovation and Carbon Dividend Act, which establishes a steadily increasing carbon fee to cut carbon emissions and return the revenue to the American people. This important and practical bipartisan legislation will grow our economy and address climate change.”
