“…Because of different rule-based statistical methods used between the 1990s, the 2000s and the 2010s, the ten categories of energy consumption could not be identified completely [43]. Under such circumstances, the only alternative method for calculating C it is through analysis of existing data and by making estimations where necessary [44].…”

h i g h l i g h t sThe relationship between urban form and CO 2 emissions is investigated. A panel data model is used, taking the period 1990-2010. The growth of urban areas correlates positively with CO 2 emissions. Increases in urban continuity has an inhibitory effect on CO 2 emissions. Increased urban shape complexity exhibits a positive influence in relation to CO 2 emissions. a r t i c l e i n f o a b s t r a c tUrban form is increasingly being recognised by scientists for the potential role it might play in the coordination of sustainable urban development and the reduction of CO 2 emissions. However, despite increasing interest in the morphology of cities in climate change science, few quantitative estimates have been made of the effects of urban form on CO 2 emissions. The goal of this study is to quantify this relation, using panel data for China's 30 provincial capital cities from 1990 to 2010. In order to meet this aim, we first selected a series of urban form indicators, which we quantified by applying spatial metrics to remotely sensed data. We then estimated CO 2 emission levels using a unified standard method recommended by the IPCC Guidelines, and subsequently performed a panel data analysis. The results of the study demonstrated a positive correlation between the growth of urban areas and CO 2 emission levels. Further, it was also found that increased ''urban continuity" led to reductions in CO 2 emissions and that, conversely, increased ''urban shape complexity" exerted a positive influence in relation to CO 2 emissions. The findings of this study indicate that measures to make existing cities in China more compact may in fact help to reduce levels of CO 2 emissions, just as increasing fragmentation or increased irregularity with respect to urban form may contribute to increased CO 2 emissions. If serious about achieving meaningful reductions in CO 2 emissions, decision makers and planners should take urban form into consideration when developing low-carbon cities in China.

“…This view is also reflects a long-standing body of theory on the relationship between the built environment and the transport sector (Cervero and Kockelman, 1997;Ewing and Cervero, 2010). Specifically, Banister (2005) identified six groups of key factors that interconnect the built environment and transport: settlement size (Hickman and Banister, 2007;Naess, 2009); urban density (Oakes et al, 2007;Liu et al, 2014;Soria-Lara and Valenzuela-Montes, 2014); land use diversity (Pitombo et al, 2010;Song and Knaap, 2004;; urban design; local accessibility (Cervero et al, 2009); and finally the provision of parking (Albert and Mahalel, 2006). Supported by the abovementioned issues, there has been a proliferation of studies based on correlating transport CO 2 emissions and built environment factors as an initial step to designing transport policy packages for CO 2 mitigation (Bart, 2010).…”

Structured abstractTransport is a major user of carbon-based fuels and is seen as crucial intervention sector for meeting CO 2 emission reduction targets. While the academic literature has traditionally focused more on correlating built environment factors (i.e. urban density, trip distance, etc.) and production of CO 2 in the transport sector, only limited attention has been paid to the influence of lifestyle factors. This paper examines the effects of lifestyle and built environments factors on transport CO 2 emissions generated by the daily commutes to and from the Autonomous University of Barcelona (UAB) in Greater Barcelona (Spain). The analysis revealed that lifestyle choices were as relevant as the built environment for understanding the emitting sources and CO 2 volume. Accordingly, the study provides insights how the design of efficient transport policy packages can integrate lifestyle factors as a central focal point.

“…However, considerable amount of energy is consumed. Although these new urban areas have wide roads and tall buildings, due to inadequate supporting facilities, such as hospitals and schools, 46 the agglomeration of labor force is limited, especially high-quality labor. 47 These new urban areas lack popularity, 48 and have even seen the emergence of an "empty city".…”

Using satellite remote sensing data and the threshold panel model, this research explores the impact of urban spatial structure on urban energy intensity. The evaluation index of urban spatial structure includes compactness and elongation rate. Results from empirical studies of 30 cities in China from 1996 to 2016 indicate that urban spatial structure has a significant impact on urban energy intensity. There is a positive correlation between urban spatial structure elongation rate and urban energy intensity. However, with the increase in urban fixed assets investment, there is a negative correlation between elongation rate and energy intensity, which implies an inverted‐U relationship. The results also indicate that urban compactness is negatively correlated with urban energy intensity. Therefore, proper management of urban spatial structure can effectively promote the reduction in urban energy intensity. The elongation of urban suburb space and the compactness with the internal space of the city can be developed simultaneously. While playing the role of a spatial agglomeration economy, the negative effects of over agglomeration are avoided, which jointly promote the reduction in urban energy intensity.
