When President Donald Trump talks about climate change, he often recycles one well-known, shaky argument: that doing anything about it will be a financial disaster. After pulling out of the Paris climate agreement, he said it was costing the U.S. “trillions of dollars that other countries were not paying.” He’s also said that President Joe Biden’s plan to boost electric vehicles threatened the auto industry with “economic destruction” (before Trump “saved” the industry by reversing it, of course). Trump has tried to scare other countries into following suit, telling world leaders last year, “If you don’t get away from this green scam, your country is going to fail.”If you look at the Trump administration’s justification for scrapping environmental protections, it always comes back to money. Officials justify these moves with estimates that almost always avoid or downplay the stunning costs of letting climate change continue unchecked, even as extreme weather brings the risk into focus. A record-breaking spring heat wave scorched the Western U.S. at the end of March, worsening wildfire forecasts and threatening the snowpack that’s crucial for the region’s water supplies. The costs are already hitting home: An analysis from the Brookings Institution in September found that the effects of climate change, from rising insurance rates to the health threats from wildfire smoke, are costing the average American household between $219 and $571 a year, depending on how much bad weather you attribute directly to climate change. For some households, the costs exceeded $1,000 a year.It’s clear that taking action to prevent such disasters doesn’t hurt the economy as a whole, said Gernot Wagner, a climate economist at Columbia Business School, but it does hurt some industries — namely, oil companies. For decades, the fossil fuel industry has been promoting the story that taking action on climate change is too costly. “There is this prevailing narrative out there, and I guess what I would say is that this is not by accident,” Wagner said. In the early 1990s, the American Petroleum Institute began commissioning economists to produce research that made any effort to rein in greenhouse gases appear prohibitively expensive. One industry-funded study in 1991 calculated that imposing a carbon tax of $200 a ton would shrink the U.S. economy by 1.7 percent by 2020. It ignored the cost of failing to act on climate change.The tradition continues today through the Trump administration’s cost-benefit calculations for repealing environmental regulations. For decades, the Environmental Protection Agency accounted for the health benefits of cutting air pollution — such as avoided asthma attacks and premature deaths — when it created cost-benefit analysis for approving clean air rules. That changed in recent months, when the Trump administration’s EPA revamped the practice so that it now effectively treats the value of saving human lives at $0. It has also thrown out the “social cost of carbon,” a metric that estimates the economic damage from floods, droughts, and other effects of global warming, which the Biden administration had set at $190 a ton. Last June, an investigation by The Associated Press found that Trump’s EPA consistently emphasized the costs of pollution rules while omitting their benefits — even though for 17 of the 20 rules AP examined, the benefits outweighed the costs, sometimes by a lot.When the agency rescinded its fuel efficiency standards for vehicles in February, along with its own ability to regulate climate change, it promised that the new fuel standards would save Americans $1.3 trillion in car payments by 2055. But a chart buried in the EPA’s regulatory impact analysis found that fuel purchases, vehicle repair, insurance, and other costs would add up to $1.5 trillion over that same time period, outpacing any savings from the repeal. Another problem became clear after the U.S. and Israel’s war on Iran caused average gas prices in the U.S. to surge above $4 a gallon: The administration’s savings estimate had assumed that gasoline prices would stay around $3 per gallon over the next 30 years.Though you wouldn’t know it from the Trump administration’s projections, protecting the environment can provide a boost for the economy. The Clean Air Act, passed in 1970, not only succeeded in reducing pollution, it also helped economic growth and productivity. Research has shown that the United States’ gross domestic product was 1.5 percent higher in 2010 than it would have been without the legislation, because exposing kids to less air pollution made for more productive workers later. And if buying clean technology costs you money — well, that’s a boost for the economy, too. “If the government forced you to cut your gas line and install an induction stove and a heat pump, OK, you might hate it because you are forced to pay money for it, but somebody is going to benefit,” Wagner said.
