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
