The Paris Agreement compared to the Kyoto Protocol has a distinct characteristic of all non-party stakeholder’s participation including civil society, private sector, and other subnational authorities to respond to climate change. This study develops Green Infrastructure Performance Index(GIPI) to measure, report and verify greenhouse gases reduction impacts on climate change policies particularly focusing on road transport sector in Korea. It is applied with 16 metropolitan areas to provide policy planners with valuable reduction information and practical and on-time policy implications. The empirical findings show that applying to traffic avoidance, technology improvement, and modal shift strategies through GIPI with the 9 core indices (eco-driving activity, electric vehicle usage, mileage-based auto insurance, etc.) that set target achievement in 2030 is projected to reduce 34.7 mill. CO2-eq, accounting for 11.2% above the national carbon dioxide reduction target of 25.9 mill. CO2-eq by 2030.
