As the transport sector is a major source of greenhouse gas emissions, the effect of urbanization on transport CO2 emissions in developing cities has become a key issue under global climate change. Examining the case of Xi'an, this paper aims to explore the spatial distribution of commuting CO2 emissions and influencing factors in the new, urban industry zones and city centers considering Xi'an's transition from a monocentric to a polycentric city in the process of urbanization. Based on household survey data from 1501 respondents, there are obvious differences in commuting CO2 emissions between new industry zones and city centers: City centers feature lower household emissions of 2.86 kg CO2 per week, whereas new industry zones generally have higher household emissions of 3.20 kg CO2 per week. Contrary to previous research results, not all new industry zones have high levels of CO2 emissions; with the rapid development of various types of industries, even a minimum level of household emissions of 2.53 kg CO2 per week is possible. The uneven distribution of commuting CO2 emissions is not uniformly affected by spatial parameters such as job-housing balance, residential density, employment density, and land use diversity. Optimum combination of the spatial parameters and travel pattern along with corresponding transport infrastructure construction may be an appropriate path to reduction and control of emissions from commuting. 展开更多

Adaptation and mitigation measures and changes in production and consumption patterns are necessary to face the risks of the impacts of global warming. They imply large investments the costs of which companies and governments, in charge of elites are not always willing to endure. Changes in elites have a direct impact on public policy and environmental governance of societies. Are the new elites willing to change traditional patterns of energy consumption if the change could threaten investment and economic growth3 Based on empirical research this paper analyzes the role of elites in a developing Latin American country (the Chilean case) in decisions adopted about the explanations of climate change and specially on the set of measures for adaptation and/or mitigation, focusing on the energy sector of the economy, one of the key sectors directly implied with the possibilities of reducing greenhouse gases emissions. 展开更多
