| Summary/Abstract |
With rapid economic growth, the transport sector plays an important role in China's CO2 emissions. The existing research is extensively concerned with transport sector CO2 emissions in recent years, but little attention has been paid to regional differences. This paper investigates CO2 emissions in the transport sector at the national and regional levels using the STIRPAT model and provincial panel data from 1995 to 2010 in China. The results showed that passenger transport dominates CO2 emissions in the transport sector, but its influence varies across regions. Electrification has significant potential to lower CO2 emissions because of resulting higher fuel efficiency and reduced pollution. Energy efficiency improvement is effective but limited in reducing emissions due to increasing demand from economic development and population growth. These results not only contribute to advancing the existing literature, but also merit particular attention from policy makers in China.

| Summary/Abstract |
This paper presents the life cycle environmental impacts and economic costs of the passenger transport sector in Nigeria for 2003-2030. Four scenarios are considered: business as usual (BAU); increased use of public transport (buses) at the expense of cars (LOWCAR) and motorcycles (LOWMC), respectively; and high economic growth with increased car ownership and decline of public transport (HICAR). The findings show that for the BAU scenario the life cycle environmental impacts double over the period, despite the assumption of increased fuel and vehicle efficiency of 35% over time. The total fuel costs at the sectoral level increase three times, from US$3.4 billion/yr in 2003 to US$9.7 billion in 2030. Increasing the use of buses would reduce the environmental impacts on average by 15-20% compared to BAU; at the same time, the total fuel costs would be 25-30% lower. If the use of cars grows much faster due to a high economic growth as in HICAR, the environmental impacts and fuel costs would increase by 16% and 26%, respectively. These results demonstrate clearly that future transport policy in Nigeria should promote and incentivise public (bus) transport as a much more environmentally and economically sustainable option than transport by cars and motorcycles.
