Book Description
China's transport sector has experienced a rapid growth in the last two decades, which causes heavy related carbon emissions and environmental pollutions due to its feature of high energy-intensive. A number of scholars have conducted studies to identify the sector's potential energy savings and to improve the energy efficiency. However, all of them focus on the direct energy consumption occurred during the operation of transport. Indirect energy use along the sector's supply chain is often neglected. At the same time, regional heterogeneity of transport sector's energy consumption should also be paid enough attentions. In this paper, multi-regional input-output (MRIO) model is applied to measure the direct and the indirect energy use of China's transport sector in 2012, where both the provincial and sectoral levels are taken into account. The results are shown as follows: (1) Energy use embodied in intermediate use is the most, which indicats that transport sector mainly serves for delivery of products and services. (2) Provinces are classified based on energy use and energy intensity, where most provinces in eastern region have high energy consumption and relatively low energy intensity and most provinces in central and western regions have relatively low energy use and high energy intensity; (3) From the perspective of energy transfer with the other sectors, energy sectors are the main providers for transport, while it supplies most energy to service sector and construction sector; (4) From the perspective of inter-provincial energy transfer, transport sector's energy flows from resource-intensive provinces located in central and western China to resource-deficient provinces in eastern China. Besides, a close geographical connection exists in the energy transfer. Based on the results, energy policies from the sectoral and provincial level are provided for policymakers.

Book Description
This book is the first comprehensive analysis of transport efficiency in China. It presents a series of rigorous empirical analysis for the operation and environmental efficiencies of major transport sectors, including highway, railway, civil aviation, and waterway. It also evaluates transport safety of China. The book innovatively employs a DEA model based on Epsilon measures (EBM) to evaluate transport efficiency and an EBM DEA model with undesirable outputs to calculate transport environmental efficiency. The factors of transport efficiency are quantitatively studied, including economic growth, social transition, and technology changes. Also, China's policies aimed at improving transportation efficiency are evaluated. The theoretical analyses and discussions would enhance our existing knowledge of the changes and determinants of transport system’s efficiency in a context of rapid urbanization, industrialization, and marketization in China. The findings of the existing policy evaluation would bring fresh evidences for transport policy performances to both scholars and politicians. In particular, it shows policymakers the experiences or lessons of how to create an efficient transport system in order to save energy use, reduce GHGs emissions, and improve social security. This book is of great interest to scholars interested in sustainable transport, regional planning and development, environmental policy and is relevant to China and other developing countries.

Book Description
Urbanization is reshaping China's economy, society, and energy system. Between 1990 and 2008 China added more than 300 million new urban residents, bringing the total urbanization rate to 46%. The ongoing population shift is spurring energy demand for new construction, as well as additional residential use with the replacement of rural biomass by urban commercial energy services. This project developed a modeling tool to quantify the full energy consequences of a particular form of urban residential development in order to identify energy- and carbon-efficient modes of neighborhood-level development and help mitigate resource and environmental implications of swelling cities. LBNL developed an integrated modeling tool that combines process-based lifecycle assessment with agent-based building operational energy use, personal transport, and consumption modeling. The lifecycle assessment approach was used to quantify energy and carbon emissions embodied in building materials production, construction, maintenance, and demolition. To provide more comprehensive analysis, LBNL developed an agent-based model as described below. The model was applied to LuJing, a residential development in Jinan, Shandong Province, to provide a case study and model proof of concept. This study produced results data that are unique by virtue of their scale, scope and type. Whereas most existing literature focuses on building-, city-, or national-level analysis, this study covers multi-building neighborhood-scale development. Likewise, while most existing studies focus exclusively on building operational energy use, this study also includes embodied energy related to personal consumption and buildings. Within the boundaries of this analysis, food is the single largest category of the building energy footprint, accounting for 23% of the total. On a policy level, the LCA approach can be useful for quantifying the energy and environmental benefits of longer average building lifespans. In addition to prospective analysis for standards and certification, urban form modeling can also be useful in calculating or verifying ex post facto, bottom-up carbon emissions inventories. Emissions inventories provide a benchmark for evaluating future outcomes and scenarios as well as an empirical basis for valuing low-carbon technologies. By highlighting the embodied energy and emissions of building materials, the LCA approach can also be used to identify the most intensive aspects of industrial production and the supply chain. The agent based modeling aspect of the model can be useful for understanding how policy incentives can impact individual behavior and the aggregate effects thereof. The most useful elaboration of the urban form assessment model would be to further generalize it for comparative analysis. Scenario analysis could be used for benchmarking and identification of policy priorities. If the model is to be used for inventories, it is important to disaggregate the energy use data for more accurate emissions modeling. Depending on the policy integration of the model, it may be useful to incorporate occupancy data for per-capita results. On the question of density and efficiency, it may also be useful to integrate a more explicit spatial scaling mechanism for modeling neighborhood and city-level energy use and emissions, i.e. to account for scaling effects in public infrastructure and transportation.

Book Description
The key findings obtained in this study include the following aspects. First, the results of SDA indicate that the energy consumption trajectory of China's construction sector is the result of competition between the effect of increasing final demand and improvement in energy efficiency. Although consistent efforts in structural optimization by the central government had significant positive effects between 2007 and 2010, the potential to reduce much more energy remains dependent on optimization of energy structure, production structure, and final demand structure. Second, the results of MRIO analysis show that the construction sector consumed 793.74 million tons of coal equivalent in 2007, which is equal to 29.6% of China's total national energy consumption. Interregional imports of the construction sector represented a resource-dependent geographical distribution, implying that the energy flows are from resource-abundant areas in the central part of the country to resource-deficient areas on the eastern coast. By contrast, energy exports represent a regional discrete distribution, which exports energy in the form of labor mobility and service supply. Third, the findings from SPA revealed that the first two stages in the upstream production process consumed the highest amount of energy in the supply chain, accounting for approximately 50% of total energy consumption. The regional analysis revealed the self-sufficiency characteristic for energy consumption in the regional construction sectors. The sectoral analysis demonstrated that imports from sectors of "manufacturing of non-metallic mineral products", "smelting and pressing of metals", and "transportation, storage, post, and telecommunications" are the most important energy flows in the first stage. The sectors of "chemical industry", "production and distribution of electric power and heat power", and mining industries pose significant indirect impact on the energy use of the construction sector. Ultimately, the comparative analyses and empirical studies of the developed hybrid framework indicate that it not only enables us to explore interregional energy transfers but also exhibits 'hidden' embodied energy consumption. The framework can also reflect the effects of changes in geographical location, building type, and building structure on the total embodied energy consumption. This study contributes the sustainable construction at three levels of investigation: national level, regional level, and project level. At the national level, the research explored the driving forces and trajectory of the embodied energy consumption of the construction sector, which revealed the potential areas for improvements in sustainable construction. At the regional level, the inter-regional energy transfers and the indirect energy input through the higher order of upstream supply chain were systematically analyzed and decomposed for the construction sector, which not only enhances our understanding of overall energy flows of the construction sector at the regional level but also reinforces the importance of specific energy-intensive paths. At the project level, the embodied energy assessment system provided valuable information in terms of embodied energy use at the early stage of a construction project, which enables stakeholders to take appropriate actions and formulate effective strategies to reduce energy use embodied in the project. From an academic point of view, the sectoral and regional analysis of driving forces, energy flows, and the supply chain provided contributions to knowledge regarding SDA, MRIO, and SPA of the construction sector. In addition, recognizing the hidden linkage in the interregional trade of China's construction sector can help with a holistic understanding of the current energy consumption status of regions and also help policy makers to achieve a fair and equitable energy reduction policy. From the viewpoint of practice, the multi-regional embodied energy assessment framework is an effective tool for pre-estimating embodied energy use at the initial stage of a project, which could provide practitioners with an incentive to develop construction sustainability.

This study analyzes the spatial-temporal pattern and processes of China’s energy-related carbon emissions. Based on extensive quantitative analysis, it outlines the character and trajectory of China’s energy-related carbon emissions during the period 1995-2010, examining the distribution pattern of China’s carbon emissions from regional and sectoral perspectives and revealing the driving factors of China’s soaring emission increase. Further, the book investigates the supply chain carbon emissions (the carbon footprints) of China’s industrial sectors. Anthropogenic climate change is one of the most serious challenges currently facing humankind. China is the world’s largest developing country, top primary energy consumer and carbon emitter. Achieving both economic growth and environmental conservation is the country’s twofold challenge. Understanding the status, features and driving forces of China’s energy-related carbon emissions is a critical aspect of attaining global sustainability. This work, for the first time, presents both key findings on and a systematic evaluation of China’s carbon emissions from energy consumption. The results have important implications for global carbon budgets and burden-sharing with regard to climate change mitigation. The book will be of great interest to readers around the world, as it addresses a topic of truly global significance.
