Climate Change and Transportation

-Alex Bigazzi

January 28th, 2009

the earth is warming
The earth is warming.
  • Beyond levels of historic global temperature cycles
  • Scientifically supported by many varied data sources
human activities are changing the climate
Human activities are changing the climate.
  • Through greenhouse gases, aerosols, soot, and deforestation/land use changes
  • Even the former president acknowledged this.
climate change is real and bad and caused by greenhouse gases
Climate change is real and bad and caused by greenhouse gases.
  • This is our starting point.
  • “Climate Change” not “Global Warming” because of various regional effects
greenhouse gases
Greenhouse Gases

Methane = 23 CO2 Eq.

N2O = 296 CO2 Eq.

car fuel economy
Car Fuel Economy

Turnover Rate?

* Estimate depends on carbon intensity of hydrogen and electricity sources

raise gas prices
Raise gas prices?
  • Shown to:
  • Reduce VMT
  • Moderate Speeds
  • Reduce Car Sizes
  • But…
  • Increased CAFÉ standards will have a much bigger effect on fuel economy (CBO brief)
  • More research needed on elasticity of demand to gas prices

impacts of climate change
Impacts of Climate Change
  • Operations
  • Evacuations
  • Flood closure
  • Airport delays
  • NW Passage?

Increasing . . .

  • Infrastructure
  • Flooding
  • Erosion
  • Thermal deformation
  • Stability
  • Bridge clearance
opportunities
Opportunities
  • New administration
  • Congressional activity on reducing GHG
      • New surface transportation act in 2009
  • Copenhagen int’l meeting to renew Kyoto (Dec. 09)
  • Green is in (look at advertising)
  • Indirectly a nat’l security issue (energy indep.)
    • We need new research, policies, and designs (this means you!)
