(1/9) Iโve seen a lot of op-eds about how awful it is that #CCS was included in the #IRA. Most lack nuance, because they havenโt clocked that the #energytransition isnโt just about the power sector anymore. Sorry #energytwitter. So, a ๐งต on why carbon capture still has a place.
(2/9) First, I get this. I was a huge #CCS skeptic. Two things changed my mind: modelling pathways to #netzero for materials with my @BloombergNEF team, and the #BNEFNEO team's carbon budgets for industry. Sobering work that taught me a lot.
(3/9) Some industries just canโt do without CCS. Process emissions are just as harmful as combustion. And weโre past the point where abatement of emissions is enough. That means removals, which means #DirectAirCapture.
If you ever wanted to acquire #carbonoffsets, you've surely faced the question of categorization. Here is an easy taxonomy ๐ ๐งต
1/ Two weeks ago I highlighted the difference between carbon emission reduction and removal projects.
The idea of #CarbonReduction is to pay others to reduce emissions in your place. But your output remains in the system. One plus zero.

Today @POTUS unveiled the #AmericanJobsPlan that includes transformative investments in clean energy that could kickstart the economy, create millions of good jobs and tackle the #climatecrisis head on. Here are a few key measures in the proposal [THREAD]
Electric Vehicles: $174 billion to compete in the global #EV market and support American workers to make batteries and EVs, electrify federal fleet, replace 50,000 diesel transit vehicles & work w/ state/local governments to build national network of 500,000 EV chargers by 2030.
Electric School Buses: Electrify at least 20% of US school bus fleet through new Clean Buses for Kids Program at @EPA and set the country on a path to 100% clean buses. Our analysis shows electric buses can have major health, cost-savings & jobs benefits. wri.org/publication/maโฆ
