The EU pays BigCem billions in EU ETS to keep polluting. The SEI co-wrote a 2016 report, the EU then closing its ETS to external offsets & hence innovation-funding is killed

As the SEIs head of *industrial transformation* could you confirm my understanding is correct @GokceMe?👍 #TSLA has a clear need & justification for Carbon credits redeemable in a mandatory ETS, as an *avoidance* measure. But what of industrial-process avoidance innovators? Did your thinktank's 2016 report forsee them *totally* shut-out of the EU ETS @GokceMe?

Very good piece Ms. Klein. I'm educating myself over ETS. This is the 1st I've read that looks into the difficulties of avoidance (rather than removal) offsets. But I'm focused only on industrial-innovation avoidance tech for low-CO2 cement @GreenBiz 🧐
greenbiz.com/article/quest-… I dontäs see how that faces the same issues as the "avoidance" motivation is not to (say) prevent trees from being dug-up. Rather, it is a straight swap of Portland cement's 820+ kg CO2/tonne for something less. And in some cases much much less.

@mc_ames @mc_ames @SEIclimate @mlaz_sei @CarbonLimitsAS @INFRAS_CH @oekoinstitut

Hopefully you'll take a look at the graphic in this thread, posted months ago to an excellent piece by @BrantWalkley. IMO your 2016 report is how the EU ETS became closed-off
threadreaderapp.com/thread/1386245… @BrantWalkley here are my tweets yesterday so hopefully you get an insight into the deeper background.

INNOVFUND then controls the supply of cash to *chosen* innovators made possible by the EUs closed-shop ETS cartel.

We need a liberalised EU ETS 👍

"Shifting completely to sustainable cement could, depending on technology used, save between 1.72 & 2.75 bn tonnes CO₂ annually"

I much enjoyed your piece @BrantWalkley but IMO the biggest block perhaps now standards 🤔

Have you looked at EMCs?
theconversation.com/sustainable-ce… FYI. It states, EMC volcanics hit 95C at 55% OPC replacement using 335 kg total cementing materials, tests by BASF. I spoke to 7 RMC suppliers...they never heard of such results using volcanics as an input

I think it's game-changing now fly ash is over 🧐

Great piece @borghesi_simone @FSR_Energy. I've been learning a lot about the EU ETS cartel.

IMO the reason for closing it off to external offsetting is definitely NOT because of the Paris Accord, which you could've stated. It's ONLY about the €€€ 👍

fsr.eui.eu/eu-emission-tr… The report used to justify closing-off the EU ETS states at p.161 "A further shortcoming of crediting mechanisms is that they do not make all polluters pay but rather subsidize the reduction of emissions"

Hence, *avoidance* INNOVATION is CLOSED OUT 🤭

CCS is a fossil fuel enabler. @jshieber's piece lays bare the difficulties innovators such as @CharmIndustrial (400 tonnes CO2) & @CarbonCure face.

We need an ETS that allows a transfer of cash to innovators. An ETS that doesn't pay polluters.
techcrunch.com/2021/04/22/as-… Per CarbonCure's website 42,552 t CO2 saved in 603,629 truckloads. A truck is 6m^3.

That's 70kg CO2/truck. So, 11.6kg/m^3 concrete.

1 cubic meter concrete is typicality 350kg cement

Hence, @CarbonCure sequesters ~33kg CO2 per tonne cement

1 tonne of cement is 824 kg CO2

"Carbon pricing is key to reach net zero GHG emissions - there is no other way to reach that target, the price needs to remain on a high level"

Okay @PIK_Climate, but do you suggest imposing it without democratic consent?

nature.com/articles/s4146…

PDF: nature.com/articles/s4146… It's a great insight you provide but you shy away from suggesting pathways to enable a true mandate. Instead, CO2 "polluter pay" doctrines have NOT worked because they favour polluter INCUMBENTS and not innovation. So now think "Porter Model". Yes?

Great @fionaharvey👍 but Mark Carney has no credibility for me after Brookfield & his TSVCM report calling-in buddy Bill Gates, for MC to then join @stripe's board that invested in Gate's @CarbonCure, now rewarded by @elonmusk. I applaud @DonnachadhMc 👏
theguardian.com/business/2021/… See below for the @DonnachadhMc piece.

Follow the breadcrumbs👍 There's an unelected plutocracy forming @fionaharvey, that's going to control #ClimateAction cash. DAC is cloud-cuckooland unless huge OPEX is funded from consumers who have no constituency

Hi @EricMasanet @ZhiCaoIE. See below. EMCs are zero CO2 & 10% OPCs energy need, using HEBM

95C at 55% OPC replacement using volcanics, TC 335kg/m^3, testing BASF

Learn about concrete, you'll know that's stellar. Otherwise, you really shouldn't be writing a @ClimateWorks report Either you know nothing about concrete & should be nowhere near writing a report, or you do know about concrete & missed-out EMCs deliberately (after all, there's a picture at p.2)

So what's the truth @ClimateWorks? Incompetence or withering bias? It's a huge miss @JesseJenkins

"The winner was CarbonCure, which showed it can inject CO2 into water used to wash out cement trucks, for a mix that makes stronger concrete, according to XPRIZE."

@elonmusk @PeterDiamandis can you send a link that supports this claim. I can't find it 🙏

phys.org/news/2021-04-w… Image I think I got it: "The mix design was to achieve 35 MPa at 28 days. The mix was 308 kg cement + 77 kg slag per m^3 concrete". That's 385kg total cementitious incl slag. That's large, yet only 35C? 🤔

And the brown bars seem to contradict your claims? 🧐

@robbie_andrew @CharlieJGardner @COP26 @HaahrMarianne @CHerweijer Yeah. That's why I tapped you. The 65% is per the 2011 doc p56: "default CaO content in clinker of 65% is recommended, corresponding to [0.51] CO2/clinker".

I get it. But I can't get to 0.4 stated by the UN, but it will set a benchmark. Very worrying if it's a howler. Seriously @robbie_andrew @CharlieJGardner @COP26 @HaahrMarianne @CHerweijer @SvenTeske
Dear Dr. Teske. Hopefully the thread above will make sense. From where does your report's p.59 "Sectoral pathways to net zero emissions" derive the 0.4 CO2/clinker ratio:
"process emissions...are assumed to decline evenly from 0.4 tCO2/t clinker in 2017–25..." 🙏
