| Nowadadys,with the rapid economic development,environmental problems such as climate warming and energy consumption have become increasingly serious.Actively responding to global climate change and seeking sustainable development paths have become urgent issues facing countries.The transport sector is closely related to social production and residents’life.At the same time,it is also a highly energy-dependent industry.It has now become one of the world’s largest energy consumption and carbon emission industries.At the same time,due to the different development stages and economic characteristics of the Belt and Road countries,their ability and driving factors of ecosystems to withstand the ecological pressure of carbon footprints on transportation energy are significantly different.Therefore,studying the ecological pressure of carbon footprints on transportation energy and its driving factors is of great significance for the development of low-carbon transportation in the Belt and Road countries.Based on this background,this study first proposes the ecological pressure of carbon footprints on transportation energy based on the ecological footprint theory,and measures the carbon emissions of transportation(CTE)and the ecological pressure of carbon footprints on transportation energy(EPCFT for the Belt and Road countries between 1995 and 2017.And analyze the results of the differences in space-time evolution.Second,LMDI factor decomposition method is used to decompose the driving factors of EPCFT in belt and road countries..Finally,the Tapio decoupling index model between EPCFT and transport economic growth was constructed,and the respective decoupling states are analyzed from the overall area,each country,and the transportation energy consumption structure,so as to provide low-carbon transport strategies for the Belt and Road countries.The research results show that during the study period,the CTE and EPCFT showed a trend of increasing total volume but slowing down in the Belt and Road countries.Therefore,it is necessary to reduce the EPCFT by increasing the area of productive land.Among the various driving factors,the effect of the economic development on the growth of EPCFT is the largest.At the same time,for various types of countries,the various driving factors affecting EPCFT are different,so it is necessary to take corresponding measures accordingly.In addition,the the Belt and Road countries have not yet achieved a decoupling state between the economic development of transportation and low-carbon transportation,but the decoupling state is generally on a good trend.From the perspective of the transportation energy structure,there is a strong decoupling between the transportation output and the ecological pressure generated by coal.The ecological pressure generated by petroleum products has shown a weak decoupling state,while the decoupling state of the ecological pressure generated by natural gas and electricity is still relatively poor.Therefore,it is necessary to further optimize the transportation energy consumption structure. |
