Oh sure, it makes sense to cut the methane pollution, but not to give credit to burn more fossil fuels in the process. That’s the problem.
Plus methane’s pronounced radiative forcing is transient so you always get higher net warming when you emit CO2 based on cutting CH4.

It's a hotly-contested title, but I think "coalbed methane" -> "sustainable aviation fuel" might be Lightweight Champ of the Greenwashing World Cup.

I am begging academic economists, please consider what happens when you combust the "sustainable aviation fuel" in a plane.
Offsets don't reduce net emissions, and giving innovation tax credits to incumbent fossil fuel companies for commercially mature activities is economically inefficient.

I love how in these debates the burden of proof gets reversed, i.e. "you can't possibly tell us NOT to offset until you have a precise strategic plan for transforming the entire global sector," the absence of which is the best possible evidence for doing something other than offsetting …

And to be clear, that EPRI number is a modeling projection of cumulative expenditures into the 2040s, so significantly smaller than the global annual subsidies you cited.
But still very big money.

Air travel is right up there with agriculture as "hard to decarbonize" in my book. Not pretending I have all the answers, though I can tell you that corn ethanol is not among them.

Ah, but what's a few hundred billion dollars (per year) between friends?
All of the estimates for IRA implementation are US only, prospective, and depend on final rules (which are done for SAF but not H2/electricity). So still TBD.

Federal tax credit expenditures under hydrogen tax credit (45V), electricity tax credits (45Y/48E), and sustainable aviation fuel tax credits (40B), all based on customized GREET models.
Here's an EPRI finding that some $380-760 billion could flow through 45V alone.

Hey Ketan, do you (or does anyone else) have a sense of whether The Nature Conservancy was particularly involved in the savanna burning projects? I recently saw something from them that suggested a strong connection, but wasn't sure if it was just a handful of projects or something bigger.

What I will say about this story is that it is riveting, detailed, and very much worth your time to read.

The IRA's boosted tax credits have triggered a carbon storage boom that should ensure more & more CO2 winds up back underground. But the projects, which could cost the US hundreds of billions, raise thorny questions about net benefits & community risks. www.technologyreview.com/2024/06/12/1...

Bit of a sequencing issue here — if you're the first person to call it wacky, you can easily get voted off the island for being early. But of course the solution to that is more people calling out the wackiness, I'm totally on board.

Anyway I am losing my mind over here that these absolutely insane and unjustified assumptions are being recycled by for industry advocacy purposes with the cavalier attitude that caused groups like the Clean Air Task Force to go nuclear on Mark Jacobson's bad 100% renewable energy math.

I don't think this came through as clearly as it might have in the story, but the regulator assumes CCS will be deployed in sectors where companies aren't planning to deploy CCS and the advocates are pointing to other, questionable CCS applications and saying the regulator is planning on them.
