The next major development in human civilization, the transition from fossil fuels to clean energy, is underway. Countries that produce the solutions enabling this transition will enjoy economic and employment benefits for decades. The Inflation Reduction Act is a big step forward. However, much more is needed to drive the US investment, innovation, and change required to achieve critical climate goals. A high price on climate pollution will do that, enabling the US to lead this next step in human progress.

Experts have long recommended one foundational policy to address global warming: carbon pricing. Some doubt Congress can overcome powerful pushback from the fossil fuel industry to charge it for its pollution, but internal and external pressures are mounting. Public alarm about climate change is growing. Cash-back carbon pricing is a proven popular solution with growing bipartisan support. Businesses increasingly support carbon pricing because of the predictability it provides and the competitive advantage it offers against dirtier-producing countries. Carbon pricing is spreading around the world, and US exporters will soon pay carbon pollution tariffs in trade with a growing list of countries until we price it here. The US will eventually price carbon, but the timing will determine whether we face a high or low emissions future.
Addressing a Market Failure
When pollution is free, we get too much of it. Economists warn that until the cost of climate pollution is reflected in the price of fossil fuels, market actors will fail to reduce it at the pace and scale required:
- “We cannot solve the climate crisis without effective carbon pricing.” - US Treasury Secretary Janet Yellen
- “Explicit carbon prices remain a necessary condition of ambitious climate policies.” - IPCC
The fossil fuel industry enjoys global subsidies of $5.9 trillion annually, mostly in unpaid environmental costs (IMF). We can address the market’s failure to account for those external costs by charging coal, oil, and gas producers a steadily rising pollution fee based on the carbon in their products. This price signal will engage the market's invisible hand, guiding carbon-reducing investments, innovation, and decisions throughout the economy.
What Price?
At COP27, leaders recommitted to limiting global warming to 1.5˚C above preindustrial levels. According to the IPCC, this requires reducing greenhouse gas emissions by 50% by 2030 and to net-zero by 2050. Over seventy countries have committed to net-zero targets (UN). Economists have calculated the carbon prices required to achieve those goals:
- “For a 2050 net-zero CO2 emission target, prices are US$34 to US$64 per metric ton in 2025 and US$77 to US$124 in 2030” - Dr. Noah Kaufman et al. in Nature
- “Estimates for a Below-1.5°C pathway range from $135–$6050 / tCO2e in 2030” - IPCC
Viability and Durability
A carbon tax could have a regressive impact on households and impose a competitive burden on manufacturers of energy-intensive goods. For those reasons (as well as manufactured resistance by the fossil fuel industry and free market fundamentalists), political reluctance to price carbon has delayed important federal legislation for decades.
To address regressivity, ensure the policy is popular when implemented, and support the high price required, experts recommend giving the money collected from fossil fuel producers to families in monthly per-capita cash-back rebates:
- "Carbon pricing is most effective if revenues are... returned to taxpayers corresponding to widely accepted notions of fairness" - IPCC
- “To maximize the fairness and political viability of a rising carbon tax, all the revenue should be returned directly to U.S. citizens through equal lump-sum rebates.” - Economists’ Statement
To protect business competitiveness, economists recommend applying a commensurate carbon tariff on imports and rebating exporters to levelize the built-in cost of climate pollution in trade with free-polluting countries:
- “To prevent carbon leakage and to protect U.S. competitiveness, a border carbon adjustment system… would enhance the competitiveness of American firms that are more energy-efficient than their global competitors. It would also create an incentive for other nations to adopt similar carbon pricing.” - Economists’ Statement

Carbon Pricing Signals
Several trends indicate US carbon pricing is coming soon:
- Carbon pricing has spread to 68 countries and regions, and prices are rising. The EU’s price recently tripled to $80 / tCO2. Canada uses Carbon Cash-Back and will reach $135 / tCO2 in 2030 (World Bank). All but two developed countries have a carbon price on fossil fuels.
- US exporters will soon pay some countries’ carbon prices on exports of energy-intensive goods, starting with the EU’s Carbon Border Adjustment Mechanism (CBAM). They won’t have to pay when the US is pricing carbon. Canada, Japan, and the UK are also considering CBAMs.
- Businesses recently pressured the Senate to ratify the Kigali Amendment to the Montreal Protocol to reduce hydrofluorocarbon climate pollution. Why? To avoid future trade restrictions and for a competitive advantage (Grist). The Senate ratified this international climate treaty with strong bipartisan support. Carbon pricing will be next for similar reasons.
- Support for Carbon Cash-Back is growing in Congress. All Senate Democrats but one supported including a variation in the Inflation Reduction Act (Inglis). The Energy Innovation and Carbon Dividend Act, a bipartisan bicameral bill introduced by several members of each chamber of Congress in 2017, recently had 96 co-sponsors in the House.
- National polling finds 33% of all Americans are now alarmed about climate change, up from 18% in 2017 (Yale Climate Communications). Polling results from CLCouncil and YaleCC report that 70-75% support the Carbon Cash-Back solution. In New Hampshire, 75% of the 45 towns that have voted on it passed a resolution asking for legislation of Carbon Cash-Back at the state and federal levels.
Carbon pricing is inevitable. But whether Congress does it in time for the US to lead the global transition to clean energy and give the world its best chance for a safe climate future is up to us. Businesses can lobby for it, and we can all tell Congress we support Carbon Cash-Back to help them do it at cclusa.org/write-cfd.
