The Trump administration’s estimate was lower for two reasons: It accounted for climate damage only within U.S. ![]() Why Trump’s social cost was so much lower Using models to produce such estimates have become a routine part of policymaking, but they are also massively uncertain. The Biden administration set the interim social cost to rise to $85 by 2050 to account for greater impact of climate change over time. These models use emissions scenarios to estimate future climate change, and then calculate the effects on the country’s - and the world’s - GDP, and they can vary widely depending on the assumptions used.įor example, damage estimates for 2100 produced by the three models used in the government’s cost-setting process range from $80 to $290 per ton. Incorporating such costs might push the government to consider including electric vehicles in the future postal service fleet.Ĭurrently, economists calculate the social cost by using integrated assessment models that bring together long-term projections for population, economic growth and greenhouse gas emissions. At $51 per ton of emitted carbon, that purchase implies a social cost of $1.1 billion over 20 years. Those vehicles would burn through 110 million gallons of gasoline a year. Postal Service has asked Congress to approve $11.3 billion for a new fleet of gasoline-powered mail delivery trucks. Figuring in damage from emissions also helps it justify investments in green technology.įor instance, the U.S. Nic Antaya/Getty ImagesĪ higher social cost of carbon signals to companies that the government sees big benefits to cutting greenhouse gas emissions. The social cost of carbon can signal to automakers that stricter auto emissions rules are likely. President Joe Biden spoke at a GM electric vehicle factory in November. Instead, it influences purchasing and investments by the government, and indirectly by private companies and consumers. If that were a carbon tax paid by consumers, it would raise gasoline by about 50 cents per gallon.īut the social cost of carbon has no direct effect on the price of gasoline, electricity or emissions-intensive goods such as steel. One of Biden’s first actions as president was to reverse the Trump administration’s bargain-basement accounting of the "social cost." The Biden administration returned it to the Obama-era level, adjusted for inflation, by setting an interim social cost at $51 per metric ton of carbon dioxide that would rise over time. Even so, federal agencies are still required to consider the climate impacts of their regulatory decisions. 11 blocking Joe Biden’s interim increase in the social cost. A Trump-appointed federal judge in Louisiana issued an injunction Feb. ![]() However, how and where new cost estimates are deployed is up in the air. That might encourage regulators to push for emissions cuts in everything from agriculture to transportation to manufacturing. The Biden administration temporarily raised it and has been preparing to finalize a new social cost that’s expected to be more than seven times as high as Trump’s. The Trump administration slashed the social cost to between $1 and $7 per metric ton of carbon dioxide - low enough that it could justify rolling back EPA regulations on power plant emissions and vehicle fuel efficiency. That extra social cost can tip the scales for whether a regulation’s costs appear to outweigh its benefits. The social cost of carbon, a dollar figure per ton of carbon dioxide released, is factored into the costs and benefits of proposed regulations and purchasing decisions, such as whether the Postal Service should buy electric- or gasoline-powered trucks, or where to set emissions standards for coal-fired power plants. To try to account for some of the damage, federal policymakers use what’s known as a "social cost of carbon." A tug-of-war over the social cost This damage is what economists call a " negative externality." It is a cost to society, including to future generations, that is not covered by the price people pay for fossil fuels and other activities that emit greenhouse gases, like agriculture. Instead, the costs show up in the billions of tax dollars spent each year to deal with the effects of climate change, such as fighting wildfires and protecting communities from floods, and in rising insurance costs. When an electric company runs a coal- or natural gas-fired power plant, the greenhouse gases it releases cause harm - but the company isn’t paying for the damage.
