Abstract :
Achieving carbon neutrality has become a major national strategy for sustainability, and the recycling of recyclable resources is an important direction toward doing so. Due to the huge amounts of recyclable resources generated every year and the low recycling rate, a new Internet recycling model with great potential to increase the recycling rate has developed rapidly in China. However, low participation from residents hinders the sustainable development of Internet recycling. Through this study, we aim to uncover potential avenues for improving Internet recycling behavior. The factors influencing Internet recycling from the perspective of new technologies have scarcely been investigated. Therefore, this study used the Unified Theory of Acceptance and Use of Technology theoretical framework to explore the factors influencing residents' intentions and behavior toward Internet recycling. A questionnaire survey was conducted with 500 residents of Beijing, China, and empirical analysis was conducted using the structural equation model. The results indicated that social influence and performance expectancy significantly influence residents' intentions to participate in Internet recycling, whereas effort expectancy and perceived risk do not. Facilitating conditions and behavioral intentions were identified as influential factors for use behavior. Relevant recommendations for promoting residents' Internet recycling behavior were proposed.

Abstract :
The primary energy use in cities accounts for a large share of global energy consumption, leading to significant carbon emissions. Exploring the city's current characteristics and future trends in energy demand has policy implications for carbon reduction policy-making. We establish a city-level energy forecast demand model to predict Beijing's future energy demand. Results show that economic growth has strong positive correlations with energy consumption. Beijing's energy demand is predicted to stay at a pretty high level by the end of 2020, between 98.72 and 121.60 Mtce, or between 4.12 and 5.08 tce per capita under three distinctive GDP growth (High, Medium and Low) scenarios. Comparing with the start of historical time series 1980, this is a huge increase of 563.50% (High), 489.90% (Medium) and 423.91% (Low) in terms of total demand, while is increases of 147.98%, 120.47% and 95.81% per capita. Based on an energy structure model estimated by a Markov-chain method, we find that our predictions would follow the current trend of energy structure, making Beijing's coal demand decline towards zero share of energy consumption, natural gas rises approaching 50%, oil stays almost constant around 32.3%, electricity decreases below 20%, and other fuels keep in a small amount in 2035. We would expect to see almost 8000 kg per capita carbon emissions in Beijing if the GDP growth rate is high, and still over 6000 kg per capita if GDP growth is low. In terms of total carbon emissions, we show that though coal consumption will keep decreasing towards zero in the next years, total carbon emission still rises by 36.5-72.8% comparing with 2010. These findings can provide references for policymakers to implement some incentive policies to promote renewable and clean energy.

Abstract :
Biodiesel is a renewable and environmentally beneficial energy which has a variety of raw materials. Waste cooking oil (WCO) as one of the feedstocks has advantages not only in the environmental aspect, but also in the economy. With the increasing attention on the use of WCO for biodiesel production, some drawbacks are encountered as well. This paper aims at using SWOT analysis to find out the strengths, weaknesses, opportunities and threats of WCO as a raw material for biodiesel production. Results show strengths including guaranteed food security, energy security, and positive impact on the environment as well as offering direct and indirect jobs. The weaknesses include complex production process, low recovery rate of WCO and high standards demand for WCO as a raw material. Biodiesel produced from WCO is capable of dealing with the increasing concern of environmental protection and the demand for renewable energy. Moreover, governments have been making laws and regulations to support its development. These mentioned above are all the opportunities with the use of biodiesel. Lack of efficient economic incentive, other energy sources competitors and a small market for biodiesel can be threats for its development. © Published under licence by IOP Publishing Ltd.

Abstract :
"Internet +" recyclable resources recycling is a new recycling program which developed quickly in China over the past three years. Indenting problems faced by internee recycling programs and summarizing typical modes are in need and necessary. To better realize and promote the new recycling way in China, we investigate related governmental departments and 10 represented enterprises that put "internee +" recycling into practice in China. From our investigation, we identify the problems faced by the enterprises and show four typical internee recycling modes. Based on the problems and cases analysis, the implications for sustainable "internee +" recycling are discussed. We suggest building a connection between online and offline, establishing a variety of profit models, educating older generations on the "internee +" recycling platform, and meeting the recycling requirements on low-value recyclable resources through the application of smart machines.

Abstract :
As the world's largest energy consumer, China has set the dual goal of controlling both its total energy consumption and intensity in the 13th Five-Year Plan. As one of the most economically active types of regional units in China, urban agglomerations, composed of adjacent cities with close trade interlinks, play a vital role in energy consumption. Existing studies have provided empirical evidence of industrial transfer as a consequence of urban agglomerations, while a few have focused on whether such industrial transfers could promote the dual goal of controlling both total volume of energy consumption and intensity of all the cities within an urban agglomeration. To bring clarity to this issue, this paper attempts to measure industrial transfer and its impact on total energy consumption and intensity of the Beijing Tianjin-Hebei urban agglomeration by developing a multi-regional input-output model. The results indicate there is mutual industrial transfer between any two cities within the urban agglomeration. Consequently, total energy consumption has increased by 6258.78 thousand tons of standard coal equivalent while energy intensity has declined by 0.19 tons coal equivalent/thousand Yuan. Finally, a few policy recommendations about dual control of total energy consumption and intensity for urban agglomerations have been proposed. Our study enhances understanding of the critical role of industrial transfer in executing dual control of total energy consumption and energy intensity of urban agglomerations, thus assisting policymakers in finding ways to achieve sustainable urban transitions.

Abstract :
The perspectives and knowledge of decision makers, especially those at the provincial level, have great impact on the progress of climate change adaptation in China. Therefore, identifying knowledge gaps and enhancing climate adaptation awareness of decision makers at that level is very important. Based on this aim, we conducted a survey of climate change adaptation awareness among 85 administrative and management personnel from governmental departments responsible for climate change adaptation planning in five provinces. Study findings revealed that over half of respondents have knowledge of climate change adaptation measures, but the extent of understanding varied across different adaptation aspects and regions. Among the different aspects, understanding of measures related to human health protection was the lowest. A large majority of respondents indicated an eagerness to obtain knowledge and information about climate change adaptation, but the main barrier is a lack of training and learning material. When making adaptation plans or policies, the greatest obstacle expressed was a funding shortage. Information generated from this study can provide direction and guidance for training and educating provincial decision makers in order to improve the levels of adaptation planning and policy making.
