"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? https://theconversation.com/sustainable-cement-the-simple-switch-that-could-massively-cut-global-carbon-emissions-144837?utm_medium=amptwitter&utm_source=twitter

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 https://en.wikipedia.org/wiki/Energetically_modified_cement

I saw this in the comment section. Maybe you've looked at the EU ETS cartel? I'm getting my teeth into it but I'm not a lawyer. Check my tweets below this thread

IMO the EU ETS is closed to GHG avoidance innovators not just per the graphic but also by not allowing other ETS "in"
