Accounting On-road transportation emissions: A guide for cities
ROAD TRANSPORT EMISSIONS
• Globally, cities are responsible for 70% of
the total energy-related CO2 emissions
• Transportation is responsible for 15-20%
of the total urban emissions
• Road transport accounts for over 90% of
all urban transportation emissions
ACCOUNTING ROAD TRANSPORT EMISSIONS: GPC

Trans-boundary trips X X* X
Pass through trips Not accounted
OBJECTIVE OF THIS RESEARCH
• Accounting on-road
transport emissions: A guide
for cities builds on the GPC
• Objective: Compare and
provide guidance for cities to
account transport emissions by
any one of the 4 methods
suggested by GPC
• Developed by comparing the
methods using the case study
of Bangalore

CONCLUSIONS
• GPC methods require more work to accurately account emissions
• Measurement key for focused, ambitious actions
• Transport sector inventories: A tool for mobility plans
• GPC: A measurement tool for low carbon planning
• Measurement and performance tracking: Tools for smart cities
