Re Renewed impetus: Ne Need t to g go t to z zero a and b beyond

üUpdated long-term climate strategy üIPCC: Special Report on 1.5C ØGross emissions reductions: mitigation close to zero ØNegative emissions: compensate residual & net-negative

  • Bio-economy: sinks and material substitution
  • Bio-energy with CCS- BECCS
  • Carbon Capture and Storage - CCS
  • Carbon Capture and Use - CCU
  • Direct Air Capture - DAC

Wha What are the he cha halleng nges s and nd tr trad ade-of

  • ffs?
  • Scale: negative emissions hard to deliver; keep it as

small as possible (i.e. mitigation)

  • Competition for land
  • CCS and negative emissions both needed
  • CCU: great to enable capture, but limited potential
  • DAC: impossible to pull off? Massive amounts of low-

carbon electricity and heat

  • Transportation & storage of carbon dioxide
