Goal: Reduce GHG from transportation
• Drive less – tax on gas, miles, or GHG (miles)
• Better cars – CAFE (miles/gallon)
• Cleaner cars –
GreenCar
(GHG/mile)
• Cleaner fuel – RFS, LCFS (GHG/gallon)

Scoring and Standards
• None can be easily or directly measureed
• All need models and averaging and broad standards

Scoring
• What included (field, plant, car, iLUC)
• Where measured (local…world)
• What number (LCA or direct)
• What model (GREET, BESS, MnGREET?)

Policy linkages
• Independent / Summable
• Complementary / Synergistic
• Conflicting / Redundant

MGA policy linkages model
• This is a “what‐if”
model, not a “what‐should‐ we‐do”
model
• Emphasis on how
policies might change activities
• Focus on links among policy actions, not on implication of stand‐alone actions

• People/Firms do the best they can with what they’ve got
• People/Firms choose lowest‐cost activity that is financially, legally, and technically feasible.
• Government sets the stage so that people/firms, in doing what’s best for themselves, do what’s
best for Society.

Policies
• Convince people to do something good
• Require people to do something good
• Pay people to do something good
• Make people pay to do something bad

Today: When Policies Collide
• Stricter CAFE standard
• GHG tax
