DOI would do much better if they took their time to officially update their regs and implement better NEPA procedures.

Trying to rush around NEPA using vague authorities is probably just going to result in years of painful court battles

I'm extremely skeptical of the Department of Interior's attempt at using emergency authorities to speed NEPA reviews up to 28/14 days.

Ironically, DOI is relying on an authority that only ever existed in CEQ regs which are now gone... I expect courts will throw this idea out.

The administration's NEPA reform strategy makes increasingly little sense.

-Multiple Executive Orders are directed at CEQ but there's STILL no CEQ Chairman so nothing is happening

Climate advocates might feel hopeless with Pres-elect Trump returning to the WH.

They shouldn’t.

I wrote about how to make progress for NYT

1. Focus on innovation and industrial strategy
2. Be pragmatic about fossil fuels
3. Expand the interests that gain from decarbonization

it really breaks my brain that people will scream that climate change is an existential crisis but also that a system of endless litigation is good and fine

America can still build fast! …but only after disasters.

In my piece for The New Atlantis (now unpaywalled) I look at the Baltimore Bridge rebuild and ask why we can’t build fast all the time.

Disaster rebuilds offer some lessons for a better infrastructure process. 🧵 (1/7)
