  1. CDMC UK: Car Emissions Are Down, but Deaths Are Up Hadi Dowlatabadi & Eric Mazzi January 22 2007

  2. Background • Goal 1: • Promoting policies that address climate change. • Goal 2: • Making sure the policies are smart: • insufficient action (mitigation & adaptation) • wasteful policies (free riders) • harmful policies (unintended consequences) • ...

  3. Climate policies • Mitigation • These are policies designed to reduce greenhouse gas emissions and hence keeping climate change in check. • Adaptation • These are policies designed to help us cope with the impacts of any climate change (after mitigation). • Goengineering • These interventions manipulate climate processes and will be attempted when there has been insufficient mitigation to avert severe climate change impacts.

  4. Hallmarks of GOOD policy • Equity • the policy does not burden/reward anyone unfairly • Efficiency • the emission reductions are cost effective • Ancillary benefits • achieves intended goals and other advantages

  5. Reality • Policies are shaped by: • political expedience (e.g., German unification) • ideology (e.g., reliance on markets over regulations) • gross simplifications (e.g., little interaction)

  6. Sources of Greenhouse Gases: UK 1990-2004

  7. GHG Emissions from Autos • Reductions are possible through: • Less driving. • More people per km driven. • Lighter vehicles. • More efficient drive-trains. • Renewable fuels. • ...

  8. The UK Policy • Add a tax based on GHG emissions to purchase price of cars. • Change the way company cars are taxed.

  9. Diesel Cars • As refined as gasoline since the mid 90s. • 25% more fuel efficient than gasoline cars. • 20% less GHG emissions than gasoline cars. • But they have been more polluting and effective emission controls need: • ultra-low sulphur fuels • more expensive technology

  10. Diesel Shares EU & UK

  11. All That Tax? • The huge rise in diesel share in the UK is well beyond what was expected. • The context: • a population primed to take climate change seriously • a range of new diesel cars to choose from • ... • But the government has been quick to take credit for all of the GHG reduction.

  12. Timing Matters

  13. The Commitment

  14. Leaving It to Choice is Wrong Population Density Car Mass

  15. More Deaths • A bifurcated auto population jeopardizes those who chose to be conserve energy through buying smaller lighter vehicles.
