From Lyngfelt this morning: carbon debt from historical emissions is ~100,000€/capita.
Solution: carbon liability for emitters. Each ton we emit today will have to be removed at some point.
Enter ACORDs: Atmospheric CO2 Removal Deposits.

CDR should define its "global cooling power": a ton of CO2 out of the atmosphere doesn't decrease radiative forcing as much a ton added increases it. Timing matters, so do climate feedbacks.

Sean Low using @AmoryLovins's approach to "hard" vs "soft" energy transitions to think about the spectrum of "engineered" vs "nature-based" strategies for carbon dioxide removal. #negCO2
Hard/Soft and Nature-based/Engineered are orthogonal dimensions.
Ex: "Big Nature" (hard/natural) vs "distributed capture" (soft/engineered). #negCO2

Conclusions on strategies for CDR:
- hard paths lead to capture risks e.g. monoculture, moral hazard/extending fossil fuel use
- soft paths lead to MRV risks e.g. "how do you measure the value of not cutting down a tree?"

Macro-algae farming/sinking loses a good 40% of net CO2 removal to phytoplankton primary productivity loss. I suspect this varies *a lot* location by location.

First presentation on what is maybe the most critical enabler of the whole NET value chain: CO2 Storage, the S in CCS/BECCS/BiCCS/DACS!
Very interesting point by @Haszeldine: geological storage of CO2 is highly demonstrable — well developed tools from O&G help make remote surveying reservoir images down to ~150 tons CO2 granularity. Monitoring is <1-2% of storage cost. #negCO2
How much storage is available? “Centuries” worth of it at current emissions levels. #negCO2
The knee's bees of mineral storage: turning carbon dioxide into calcite within young basalts, e.g. as in Iceland. #negCO2
Overall problem: "Lots of research, very little action. Only 2 or 3 CO2 storage wells operating in UK, 2 in Europe."
"Because we don't have a carbon tax, there is a missing market in storage carbon dioxide." #negCO2
"Because we don't have a carbon tax, there is a missing market in storage carbon dioxide." #negCO2
So how much does CO2 storage cost?
Largest cost is capture by far. Transport and storage runs from £4 to £20 per ton of CO2 based on volume (initial phase). #negCO2
