Uncovering impact factors of carbon emissions from transportation sector: evidence from China’s Yangtze River Delta Area
2020
Transportation sector contributes a significant proportion to the overall carbon emission. This paper aims at measuring the impact factors of the transportation sector’s carbon emission in China’s Yangtze River Delta Area (YRDA) so that mitigation strategies on promoting low-carbon transportation can be raised. The partial least squares method and an extended STIRPAT (stochastic impacts by regression on population, affluence, and technology) model were employed for quantifying the contributions of different impact factors that affect transportation carbon emission within the YRDA region for the period of 1995–2014. Results show that population size, GDP, civilian vehicle inventory, energy intensity, passenger transportation, freight turnover, and transport sector output are key factors inducing transportation carbon emission, while energy structure and transportation sector employees mitigate the overall transportation carbon emission. Such results provide valuable policy implications for preparing appropriate mitigation strategies, such as the optimization of energy structure, the development of energy efficient technologies, the improvement of public awareness, and the implementation of intelligent transportation management.
