  3. 3. Key Approach, By Mode No of trips Trip length Load factor Vehicle kms Energy factor (l/km) Emission factor (gram/km) Total energy consumption, CO2 emissions Total emissions Simple Basis: Total_emission = Vehicle_kms * Emission_factor JICA EMBARQ
  4. 4. Vehicle Kilometers by Mode Source: Hanoi Master Plan
  5. 5. Passenger-Kilometers by Mode Source: Hanoi Master Plan, own estimates
  6. 6. Resulting CO emissions
  7. 7. Resulting CO2 emissions
