Effects of urban forms on CO emissions in China from a multi-perspective analysis.

Effectively evaluating the effects of urban forms on CO emissions has become a hot topic in socioeconomic sustainable development; however, few studies have been able to explore the urban form-CO emission relationships from a multi-perspective view. Here, we attempted to analyze the relationships between urban forms and CO emissions in 264 Chinese cities, with explicit consideration of the government policies, urban area size, population size, and economic structure. First, urban forms were calculated using the urban land derived from multiple-source remote sensing data.
