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 gases.

Methane = 23 CO2 Eq.

N2O = 296 CO2 Eq.

Ghg sources
GHG Sources gases.

Fossil Fuel Combustion, Iron and Steel Production, Cement Manufacture, Municipal Solid Waste Combustion, Lime Manufacture, Ammonia Manufacture, Aluminum Production, Petrochemical Production, Titanium Dioxide Production, Landfills, Coal Mining, Manure Management, Wastewater Treatment…

Assessment
Assessment gases.



Strategies
Strategies gases.


Car fuel economy
Car Fuel Economy gases.

Turnover Rate?

* Estimate depends on carbon intensity of hydrogen and electricity sources

Raise gas prices
Raise gas prices? gases.

  • 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

Fuels
Fuels gases.


Impacts of climate change
Impacts of Climate Change gases.

  • Operations

  • Evacuations

  • Flood closure

  • Airport delays

  • NW Passage?

Increasing . . .

  • Infrastructure

  • Flooding

  • Erosion

  • Thermal deformation

  • Stability

  • Bridge clearance


Opportunities
Opportunities gases.

  • 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!)
