The long list of big companies backing a carbon tax as a solution to climate change grew this week with financial giant J.P. Morgan Chase & Co. endorsing a legislative plan billed as a centrist approach to reducing emissions.
The announcement comes as the Climate Leadership Council (CLC), the organization behind the proposal, which was first released in 2017, redoubles efforts to promote the plan before an expected introduction in Congress as the conversation around various climate solutions heats up in Washington.
The CLC announced new backers—including former Energy Secretary Ernest Moniz and former UN climate chief Christiana Figueres—and released internal poll numbers showing bipartisan voter support for the plan. Supporters now include a broad coalition of companies, from oil giants like ExxonMobil to tech behemoths like Microsoft, major environmental groups like Conservation International, and a range of economists and political leaders.
One of the biggest challenges to this measure—or any carbon tax for that matter—is the growing interest in other approaches to climate legislation. Republicans this week pushed legislation to plant trees and expand tax incentives for capturing carbon, measures that wouldn’t match the scale of the challenge but allow Republicans to offer a different message on the issue. Earlier this month, Representative David McKinley, a Republican from West Virginia, and Kurt Schrader, an Oregon Democrat, called for legislation that would lead to an 80% reduction in emissions from the power sector by 2050 using a combination of regulation and funding for innovation and infrastructure. And more than 30 Democratic senators introduced a bill to require the Environmental Protection Agency to come up with a plan for the U.S. to eliminate its carbon footprint by 2050. “This is the quickest way we can jumpstart government-wide climate action,” Senator Tom Carper of Delaware, who introduced the legislation, said on the Senate floor.
None of these measures are likely to become law anytime soon, and any legislative approach to addressing climate change will involve intense debate on Capitol Hill.
Even some backers of the carefully crafted CLC plan acknowledge it’s not likely to pass in its current form. “Inevitably, Congress will have some of its own ideas in terms of the implementation,” Moniz, who endorsed the CLC proposal this week, tells TIME.“ “I would welcome seeing that negotiation start in earnest.” Indeed, even having a discussion in Congress indicates a new climate for climate in Washington.
