What do you believe?• UK will have 15% energy
consumption from renewables by 2020?
• UK will meet 4th carbon budget (1.95 bnTCO2 in 2023-27?)
• UK will reduce emissions by 80% by 2050 (cf 1990)?
• A post-Kyoto deal will be done by 2015 and enter force 2020?
• UK Carbon Price Floor will be £70/tCO2 in 2030?
• Global temperatures increases will be kept below 2 degrees?
What would you bet?

• Globally co-ordinated carbon tax• Nationally collected• Possible consumption basis• Border taxes for non-participants• Predictably rising• Very long term• No shocks
What to do 4: pricing not quantities

What to do 5: focus on specific problems• Nuclear fuel cycle management• LNG infrastructure for China• Forest and sink protection• Global sectoral agreements – automotive, aviation, steel• Carbon pricing with border tax adjustments• Grid infrastructure for desert solar concentrators• Product and building energy efficiency standards• Water trading and river basin management
• Etc etc…
