Will U.S. ever put a price on carbon as part of climate change

The world needs to reduce carbon levels, and one way is through a carbon tax, a strategy the U.S. has been debating for decades.   

With urgent calls to lower greenhouse gas emissions globally, putting a price on carbon was one of the major points of discussion among world leaders at the COP26 conference in Glasgow earlier this month. Consensus on a global carbon price is growing, according to Lord Greg Barker, executive chairman at EN+ and co-chair of the Carbon Pricing Leadership Coalition. 

“We need countries to come together to agree on international standards in order to make that big shift to the low carbon economy,” Barker told CNBC in an interview from COP26 last week. “It would be much better for the world if there was a common carbon price.” 

As of now, Barker says there are 69 countries with a carbon price ranging from $1 to $139 per metric ton. The U.S. is not one of them.  

Barker told CNBC most economists agree that carbon pricing is the most effective tool there is to transition to a low carbon economy. Carbon pricing shifts the liability for the consequences of climate change to the polluters who are responsible, according to the World Bank.

The Biden administration has outlined $555 billion in spending to confront climate change, though the plan does not address carbon pricing. The bill does include a proposed methane fee incentivizing oil and gas companies to reduce their methane emissions. 

A policy to apply a carbon tax was considered as a “plan B” during negotiations over the current climate package, according to the New York Times, after Biden’s clean electricity program was cut from the spending bill last month.

If the U.S. administration can’t get behind the rest of the world on carbon pricing, there are other ways to follow through with the initiative, says Barker, such as regulations, taxes, and emissions trading. 

The U.S. has considered carbon import fees and emissions trading that would apply to carbon-intensive products imported to the country. “But carbon import fees only make sense if you have some kind of domestic U.S. carbon policy,” says Richard Newell, president of Resources for the Future, a nonpartisan energy and environment research organization.   

He thinks a price on carbon ultimately is achievable as part of U.S. policy as the world grapples with the seriousness of climate change and turns more to financial incentives to reach a low-carbon ecosystem that supports the entire economy.

The Biden administration has a government-wide plan addressing how climate change could affect all sectors of the U.S. economy. The plan was part of a larger agenda to eliminate greenhouse gas emissions in half by 2030 and transition to a net-zero emissions economy.
