@NASEM_Climate Would you consider ~30% of methane reduction as atmospheric methane removal? Reducing CH4 emissions frees up OH radicals to remove/oxidize additional methane emissions.
This is factored into the perturbation lifetime and GWPs, but seems unrecognized by the CDR market.

@mr_james_c@yishan@AlecStapp@LowIQPigeon7 My comment had nothing to do with giving China a pass.
I was interested in whether the decrease in U.S. emissions is less impressive when accounting for embodied emissions of imported goods.
Turns out it’s significant- US emissions are -10% higher when factoring this in.
@yishan@AlecStapp@LowIQPigeon7 I wonder what this chart would look like if it accounted for the embodied emissions within goods imported to the U.S. from other countries like China. 🤔

@PeterMinor@RobertHoglund@Peters_Glen@donaldjdzepeda@aniruddh_mohan While there are multiple ways to demonstrate electricity additionality beyond vertically integrated production, DAC should be required to prove electricity additionality, or else account for the decarbonization delay they cause in the form of a discount on credits issued.
@RobertHoglund@Peters_Glen@donaldjdzepeda@PeterMinor@aniruddh_mohan Good point - agree it prob makes sense to have this at the standard vs the methodology level.
But if we agree on DAC’s effect on decarb delay, why give an exception to not account for this externality in early deployments (especially if they sell credits)?
@RobertHoglund@Peters_Glen@donaldjdzepeda@PeterMinor@aniruddh_mohan Should that risk be discounted from the Scope 2 of DAC projects?
Eg - If today’s DAC plants are responsible for a decarbonization delay, shouldn’t they account for that in the credits net credits they issue?
@RobertHoglund@Peters_Glen@donaldjdzepeda@PeterMinor@aniruddh_mohan So would it be fair to say that DAC facilities that don’t build their own renewable energy are displacing energy that could’ve otherwise been used for decarb?
I’d imagine most DAC are competing for PPAs so they’d be tainted w/ this air of cart before horse mitigation hierarchy.
@paulg Could an important factor also be the fact that liberal ideologies tend to be future-oriented, whereas conservative ideologies tend to preserve the past?
If you accept that premise, the liberal perspective is inherently more focused on the existential risks we face.
@KHayhoe I work at a company that’s bringing native methane eating microbes (“mems”) into landfills and agriculture to tackle methane emissions.
What are your thoughts on inoculating tree bark with native mems to augment methane removal?
