social cost of carbon
The Trump Administration cares about regulatory costs. Regulatory benefits? Not so much.
Since Ronald Reagan’s time, there has been a consensus among conservatives that cost-benefit analysis (CBA) should be the gold standard for regulation. That approach has given them common ground with moderates such as Cass Sunstein, many economists (whether liberal or conservative), and at least a few scholars more environmentally inclined. Cost-benefit analysis has had its …CONTINUE READING
The case for using global rather than simply U.S. impacts.
The estimated harm done by a single ton of carbon in the atmosphere – the “social cost of carbon” — is a key factor in setting climate policy. The Trump Administration is trying to get its estimate as close to zero as possible. A key part of this effort is to exclude from consideration the …CONTINUE READING
Trump rescinded the Obama Administration’s estimate. Now what?
Republicans vehemently attacked the Obama Administration’s estimate of the social cost of carbon. Trump withdrew that estimate and directed individual federal agencies to do their own estimates. The agencies will now be faced with a number of problems, and it’s not clear that they are well positioned to deal with them. They might prefer to …CONTINUE READING
President Trump’s Executive Order on climate policy is an invitation to bad policymaking and legal uncertainty. The big-ticket item targeted by the Order, of course, is the Obama Administration’s Clean Power Plan and related rules on carbon dioxide emissions from power plants. The EO has limited immediate legal impact: none of the major rules can …CONTINUE READING
The true victims aren’t you and me. It’s our descendants who will pay the price, long after Trump is gone.
We live in a time of contrasts. Yesterday, scientists reported more evidence that climate change will intensify heat waves and droughts in temperate zones through changes in the jet stream. Today, however, the Trump Administration initiated the process of eliminating federal climate policies. In a pointed insult to EPA staff who have worked long and …CONTINUE READING
Considering climate impacts isn’t just a good idea. It’s the law.
Many people seem to think that considering climate impacts and the social cost of carbon was just a policy decision by the Obama Administration, which Trump if he doesn’t buy the reality of climate change. But it’s not that easy. But there are strong arguments that considering climate change is mandatory. First, the whole idea of considering …CONTINUE READING
We can impose a price on carbon without a tax or emissions trading. Here’s how.
Cap and dividend is a politically appealing idea; put a price on carbon, then refund the money to consumers in equal shares. But conservatives and libertarians object to this idea on two grounds. First, cap-and-trade systems are complex and require a lot of regulatory oversight. Second, if the government collects the money, despite its current …CONTINUE READING
Merging Cost-Benefit Analysis and Feasibility Analysis
The U.S. government has devoted a lot of time and effort to estimating the social cost of carbon. This is basically a standard exercise in cost-benefit analysis, following a familiar three-step process: 1. Impacts. Figure out the physical impacts of the emissions. This involves setting up some emissions scenarios and then running computer simulations to …CONTINUE READING
Tomorrow’s Emission Determine Today’s Social Cost of Carbon
Here’s the weird thing: the social cost of carbon today, depends significantly on the year-by-year emissions of carbon in the future, which we obviously don’t know. (Because it depends on our own future actions!) It takes some explanation to show why that’s true and how it matters. If you know a bit about climate policy, you know …CONTINUE READING
A recent CRS report provides a wealth of information about carbon capture. You can learn a lot about the various technologies and how close or far they are from possible adoption. But for most of us, the technical details matter less than the answers to some key questions: Is carbon capture technically feasible? Can it …CONTINUE READING
