It is often difficult to determine the effects of policies at a sectoral level in the overlapping domains of pollution control and energy conservation, making it difficult to consider co-benefits of energy conservation and air pollution reduction and tensions. In China, the industry sector contributes much more carbon and pollution emissions than other sectors. In this paper, Baoshan District (BSD), one of the most important industrial zones in the Shanghai metropolis, is used as a case study to illustrate the situation and to provide information to assess the effectiveness of environmental sustainable development policies in industries. The policies resulting from China's Eleventh Five-year Plan (FYP) are considered at the level of BSD. In particular, the result of implementing local policies of air pollution control and energy are analysed at BSD. Three indicator systems are adopted for quantitatively and qualitatively evaluating energy saving and air pollution reduction achieved by technical, structural and management measures in industrial enterprises of BSD. Analysis made in the paper shows that the co-benefits of pollution cutting and energy conservation have been achieved at certain scopes and degrees in the industry sector in BSD, e.g. SO2 and Particulate Matter (PM) were reduced by 35.1% and 7.7% respectively, and the energy density was cut by 26.7%. Due to existing barriers of the lack of co-planning and co-operations in the process of designing and implementing the policies, and the overlooking the leakage of emissions in the whole project area, the overall co-benefits cannot be achieved effectively in BSD. Recommendations are made for future detailed studies of this or similar districts to develop an indicator system of co-benefits to help demonstrate the advantages of joint planning and policies for co-benefits. © 2015 Elsevier Ltd.

With the high growth urbanization and increasing new urban population, the huge demand for infrastructures and dwellings has become a great challenge for the sustainable development in Chinese cities. The building sector shares one fourth of total energy consumption in the country and plays an important role in reducing the energy consumption and the consequential green house gas (GHG) emissions. Some policies have been issued for promoting the low carbon sustainable development in China's buildings. However, existing barriers especially the investment barriers substantially prevent the low carbon technologies and service from being employed effectively. The carbon trading scheme of cap-and-trade is now widely accepted as one cost-effective way to deal with the climate change issue in the world, and it can be utilized for overcoming the barriers to carbon reduction activities in China's building sector. A new Clean Development Mechanism (CDM) energy performance based method is designed for reducing transaction costs in implementing CDM projects in China's buildings before 2020. And then a "step by step" approach is formed to establish the domestic and international carbon trading mechanism to effectively reduce GHG missions in China's building sector after 2020. © 2015 Elsevier Ltd.

The unprecedented resources and energy needed to support the high growth of urbanization with the emerging issues of environmental degradation and GHG emissions is increasingly dramatic in China. A series of national and local policies have been implemented for achieving the co-benefits of reducing emissions of greenhouse gas (GHG) and air pollution for China's sustainable development. In this paper, the achievement of climate change mitigation and air pollution reduction in different sectors through implementing policies is reviewed. This paper reports on the types of policy measures that have been introduced in two cases (i.e. Tiexi District of Shenyang and Baoshan District of Shanghai) to affect air quality and energy efficiency improvements, which are then collectively examined in terms of their impacts on GHG and air pollutant emissions. Recommendations are made for achieving co-benefits effectively through the integrated approach by comprehensively concentrating on the short and long-term environmental protection and energy conservation at local and national levels based on the analysis made in the paper. The limited coordination and lack of capacity in different government bodies may be the main barriers to the implementation of a co-benefits approach. Enhancing the cooperation and capacity building could overcome these obstacles. © 2013 Elsevier Ltd. All rights reserved.

Low carbon sustainability has been addressed in China's national development strategies. This research explores individual behaviour change and engagement in building low carbon communities in China through a case study looking at the building of a low carbon campus at Fudan University, Shanghai. Individual behaviour directly influences the overall energy consumption and carbon emissions on Fudan University's campus. Even though relevant polices have been issued for energy conservation, the energy consumption increased by 5% every year, which suggests that the "top-down" approach telling students and staff "what to do" does not work effectively. Based on a comprehensive method which includes the individual and social aspects related to the energy behaviour, the research analyses the promotion of individual engagement in building a low carbon campus through behaviour change based on four main aspects: (1) awareness raising and behaviour forming; (2) approaches to encourage behaviour change; (3) beyond the barriers and the constraints; and (4) systems and mechanisms for the long-term engagement. A low carbon management system is proposed for not only addressing management and technical solutions at the university level, but also based on the contributions from behaviour changes in establishing a low carbon campus at Fudan University at the individual level. © 2013 Elsevier Ltd.

Leaf nitrogen (N) and phosphorus (P) stoichiometry might reflect the biogeochemical features of ecosystems, yet the potential range of stoichiometric flexibility under geochemically P-enriched soils (GPES) is still unclear. Leaf N and P of 126 plant species in 70 vegetation plots in GPES were investigated in central Yunnan, southwestern China, and leaf P fractions (i.e., inorganic vs. organic P) of the dominant species were examined. Our objectives were to improve the understanding of the role of soil N and P variability in controlling leaf N and P stoichiometry of plant communities in GPES. We found that plants in GPES had higher mean leaf P (4.07 mg/g) and lower N:P ratios (4.94) than average plant values that have been recorded in other parts of the world so far. Some fast-growing plants had extremely high leaf P (>10 mg/g). Community leaf N and P contents increased as soil N availability increased, but soil N variability was unrelated to community leaf N:P. Instead, community leaf P and N:P ratios were primarily determined by soil P; as soil P availability increased, leaf P increased and leaf N:P significantly decreased. Greater accumulation of inorganic P relative to organic P in leaf was the direct driving factor for community leaf P and N:P ratio patterns in GPES. Although soil P availability was the main controlling factor of leaf N:P patterns, community composition could be manipulated to restore the balance of N and P stoichiometry based on the different responses across species and plant types. © 2015, Springer-Verlag Berlin Heidelberg.

Two main energy performance benchmarking methods under the National Public Buildings Energy-efficiency Design Standards and the Evaluation Standard for Green Building are adopted for saving energy consumption in the public buildings in China. However, several existing barriers and weaknesses in current benchmarking systems prevent the overall energy conservation and carbon reduction from being achieved. This paper explores a new comprehensive energy performance based benchmarking method for addressing the energy saving from both technical and non-technical measures. The overlooked base load energy use is also highlighted in the new method. More importantly, the approach of establishing accurate and efficient data bases and forming sound baselines for assessing and monitoring the energy performance in different types of China's public buildings are recommended in the paper. Governments can play a vital role in improving current benchmarking systems for promote the comprehensive low carbon sustainable development in China's public building sector. © 2014 Elsevier B.V.
