Understanding the mitigation potential of sustainable urban transport measures across income and gender groups

The global climate is going through a transformation due to increased GHG emissions. Urban transportation is one of the leading contributors to increased GHG emissions due to its dependency on fossil fuels. Mitigation measures are evaluated globally to reduce the emissions from the transport sector. These mitigation strategies have a disproportionate effect on the income-gender groups, and the emissions contribution is non-uniform across income levels and gender. It is imperative to understand the emissions contribution of these groups. In this study, the CO2 and PM2.5 emissions from a combination of eight income-gender groups together are estimated for four urban transport mitigation policy bundles. Further, the emission potential of each mitigation policy bundle for each income-gender group is calculated by comparing emissions from each policy bundle with respective BAU scenario emissions. For a better understanding, policy implication on each income-gender group's specific travel parameters like mode share, average trip length and vehicle kilometres travelled are also assessed. Bundle 4, which is a blend of planning, regulatory, economic and technological policy instruments, showed the highest mitigation potential across all income-gender groups. The study finds that the majority of the female groups showed the highest mitigation potential for both pollutants for 2030 and 2050.

Automated summary

This study evaluates the emissions contribution of different income-gender groups to urban transportation mitigation policies. The findings indicate that a combination of various policy instruments has the highest mitigation potential across all groups. Additionally, the study reveals that the majority of female groups show the highest potential for reducing emissions of both CO2 and PM2.5 in 2030 and 2050.
