An Easy, No-Fuss, Climate Fix for that Big First Day in Office

No, not rejoining the Paris Agreement, though that’s a good idea too. Something else.

This is kind of like one of those recipe things you see: putting a gourmet meal on the table in five minutes.  But it’s more like: the one ingredient that will make all your recipes come out better.  More seriously, what I’m about to propose is very conventional, easily integrated into agency procedures, and a …

The Rise of Benefit-Blind Analysis 

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 …

The Social Cost of Carbon – Revisited

The case for using global rather than simply U.S. impacts.

Trump’s Executive Order: Bad Policy and More Uncertainty

Trump’s Frontal Assault on Climate Policy

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 …

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.

A Small-Government Approach to Pricing Carbon

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 …

The Shadow Price of Carbon

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 …
