I am very happy to be at the Negative emissions conference in Gothenburg!

Starting a mega-thread with learnings.🧵 #NegCO2
@Anders_Lyngfelt (one of the organizers) on BECCS:

- 50 million ton CO2 already stored geologically world wide (mainly for EOR)

- BECCS using chemical looping combustion is estimated to cost just €20-25/t (on existing facilities).
I like Lyngfelt and @MathiasFridahl proposal for financing CDR. Make emitters deposit funds later used for removals. Similar to carbon takeback obligations @MargrietKuijper Image

For example, diet change is not something normally assessed.
. @DetlefvanVuuren explains kinds of life-style change required for 1.5C pathway whilst greatly reducing reliance on BECCS.

"Only eating beef once a fortnight"
