Calculating the Extinction Cost of Carbon
Or, how many megatons do we need to cut to prevent one extinction?
Economists often talk about the social cost of carbon, which basically translates the harm done by a ton of CO2 into dollars. The dollar metric is less useful as applied to ecological impacts like species extinctions than impacts of humans. It may be better to skip the dollar conversion, and just ask how much a …

There are small but hopeful signs of progress in overcoming legislative gridlock.
Over a decade ago, the Waxman-Markey carbon trading bill died in the Senate. President Obama then had to rely entirely on administrative actions to address climate change. Republicans united in a solid wall of violent opposition to climate action. There are some hopeful signs that things may not be quite so tough for President Biden. …

CONTINUE READINGWhy I Was Wrong About Methane
I didn’t think cutting methane was a high priority. Now I do. Here’s why.
I didn’t use to think that eliminating methane emissions should be a priority. True, methane is a potent greenhouse gas. But it’s also a short-lived one, which only stays in the atmosphere for twenty years or so. In contrast, CO2 emissions cause warming for 2-3 centuries or more. So methane emissions seemed to be something …

CONTINUE READINGThe Hidden Green-Infrastructure Bill
Every year, Congress provides lavish funding for clean energy and climate adaptation. No one notices.
Biden’s green-infrastructure bill is headline news. Republicans are up in arms. Yet every year there’s already a green-infrastructure bill. Hardly anyone notices. Republicans vote for it without a fuss. Why? It’s part of the annual funding bill for the military. The Defense Department remains the biggest single consumer of energy in the country, and it …

CONTINUE READINGThe Turning Tide
Last week featured some remarkable developments relating to climate policy.
Some events last week sent a strong signal that the tide is turning against fossil fuels. Each of the events standing alone would have been noteworthy. The clustering of these events dramatizes an important shift. To paraphrase Churchill, this may not be beginning of the end for fossil fuels, but at least it is the …

A court orders Shell to cut its emissions, including of its consumers. But will this stand after appeal?
In recent years, The Netherlands has become the leading site of climate change litigation. Contrary to expectations (including my own!), its district, appellate, and supreme courts decided in favor of Urgenda, an upstart environmental organization, ordering the government to more aggressively reduce greenhouse gas emissions. Now the same district court has gone further, again in favor of environmental groups …

Even Red-States Supported and Increased Renewable Energy during the Trump Administration
Below the federal level, it’s difficult to discern the impact that the Trump Administration had on energy policy. To take a closer look, I conducted a fifty-state survey to discern how state, local, and public utility actions affecting energy policy came together as a whole over the past four years. Across the nation, I found, …

Should we adopt a corporate carbon tax? Something to think about on Tax Day.
Today is Tax Day, delayed from its usual spot in mid-April due a backlog at the IRS. It seems like an apt time to think about a carbon tax. At present, it doesn’t seem to be on Biden’s agenda, but agendas can change with circumstances, sometimes unpredictably. Politically, the biggest problem with a carbon tax …

How can we make climate pledges something more than cheap talk?
Companies across many different economic sectors have announced ambitious goals like being climate neutral by 2050. Commitments on ESG – Environmental, Social, and Corporate Governance — are a growing corporate emphasis. Talk is cheap, however. How can we know they’re serious? How can we even be sure that the information they release about their environmental …

After much travail, the state has finally put a price on carbon.
The Washington state legislature passed a historic climate change bill on April 24. The bill requires a 95% cut in carbon emissions by 2050. After much travail, the state has finally managed to put a price on carbon by adopting a cap-and-trade system. With the decision of additional states to join the east coast RGGI …
