  16. Three interdependent problems lead to the conclusion that it is time to replace our energy system… • The Oil Problem (OP) • The Air Pollution Problem (APP) • The Climate Problem (CP) Do we have the technological know-how to construct an energy system that would solve all three problems?

  18. Stabilization Wedges: Solving the Climate Problem for the Next 50 Years with Current Technologies Stephen W. Pacala and Robert Socolow Science Vol. 305 968-972 August 13, 2004

  19. Past Emissions Billion of Tons of Carbon Emitted per Year 14 Historical emissions 7 1.9  0 2106 1956 2006 2056

  20. The Stabilization Triangle Billion of Tons of Carbon Emitted per Year 14 Currently projected path = “ramp” Stabilization Triangle Interim Goal O Historical emissions 7 Flatpath 1.9  0 2106 1956 2006 2056

  21. 21 Business As Usual GtC/yr (530) (750) 14 Ramp = Delay Stabilization triangle  850 ppm Historical emissions (470) 7 Flat = Act Now  500 ppm (850) (320) (500) (500) 1.9 (500) 2206 2156 1956 2006 2056 2106 The Stabilization Triangle: Beat doubling or accept tripling (details) (380) (850) Values in parentheses are ppm. Note the identity (a fact about the size of the Earth’s atmosphere): 1 ppm = 2.1 GtC.

  22. The Demography of Capital Historic emissions, all uses 2003-2030 power-plant lifetime CO2 commitments WEO-2004 Reference Scenario. Lifetime in years: coal 60, gas 40, oil 20. Policy priority: Deter investments in new long-lived high-carbon stock: not only new power plants, but also new buildings. Credit for comparison: David Hawkins, NRDC

  23. Wedges Billion of Tons of Carbon Emitted per Year 14 14 GtC/y Currently projected path Seven “wedges” O Historical emissions 7 GtC/y 7 Flatpath 1.9  0 2106 1956 2006 2056

  24. 1 GtC/yr Total = 25 Gigatons carbon 50 years • Cumulatively, a wedge redirects the flow of 25 GtC in its first 50 years. This is 2.5 trillion dollars at $100/tC. A “solution” to the CO2 problem should provide at least one wedge. What is a “Wedge”? A “wedge” is a strategy to reduce carbon emissions that grows in 50 years from zero to 1.0 GtC/yr. The strategy has already been commercialized at scale somewhere.

  44. Three Interdependent Problems • The Oil Problem (OP) • ~ $600 billion /yr for Iraq, • >$100 billion /yr for oil price shocks • (how much for vet care?) • The Air Pollution Problem (APP) • >$100 billion /yr for air pollution • The Climate Problem (CP) • ~ $100 billion/yr to solve the problem

  45. Conclusions What is needed is a national policy designed to solve the oil problem, the air pollution problem, and the climate problem. We already possess cost-effective technologies for the next fifty years, if costs are seen in the context of what we are already paying. The solution will only get cheaper, as investment elicits industrial R&D and new innovation.
