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

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

Mode shares in Bangalore Emissions from various modes in Bangalore

Two Wheelers have a mode share of 29% but contribute 61% to the total passenger vehicle emissions

LOW CLIMATE PLANNING: AN EXAMPLE

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
