Low-Carbon Campus Construction Based on Ecological Footprint Theory:A Case Study of Shenzhen Graduate School,Peking University

Since the sustainable development has been widely acknowledged worldwide,the sustainable campus development based on low-carbon campus construction has already become a tendency of building resource-saving and environment-friendly society.It is a hot and difficult topic in the current campus planning to measure,estimate and construct low-carbon campuses.This paper calculated the ecological footprint of traffic,water,energy and daily life on the campus of Peking University Shenzhen Graduate School,obtained the energy consumption of each item on campus and individual low-carbon activities using questionnaire survey and interview,compared the data with those of other domestic and foreign campuses.The results showed that(1) Ecological footprint of Peking University Shenzhen Graduate School in 2016 was 4,269 hm^2,and per capita ecological footprint was 1.49 hm^2;(2) Total carbon emission in 2016 was 13.4×107 kg,among which power generation and food produced the most carbon emission;(3) Students had strong awareness of low-carbon life,and the main obstacles for low-carbon life were "Hard to change living habits","Greedy vanity",and "No efficiency instruction";(4) In terms of the overall proportion,control of energy consumption is the main approach of reducing campus carbon emission,which is similar to other domestic and foreign campuses.The carbon emission of daily life in Peking University Shenzhen Graduate School was significantly higher than that of foreign campuses,while that of traffic was lower.Suggestions and improvement measures were put forward in view of the existing problems.

Progress of Air Pollution Control in China and Its Challenges and Opportunities in the Ecological Civilization Era

China’s past economic growth has substantially relied on fossil fuels,causing serious air pollution issues.Decoupling economic growth and pollution has become the focus in developing ecological civilization in China.We have analyzed the three-decade progress of air pollution controls in China,highlighting a strategic transformation from emission control toward air quality management.Emission control of sulfur dioxide(SO2)resolved the deteriorating acid rain issue in China in 2007.Since 2013,control actions on multiple precursors and sectors have targeted the reduction of the concentration of fine particulate matter(PM2.5),marking a transition to an air-quality-oriented strategy.Increasing ozone(O3)pollution further requires O3 and PM2.5 integrated control strategies with an emphasis on their complex photochemical interactions.Fundamental improvement of air quality in China,as a key indicator for the success of ecological civilization construction,demands the deep de-carbonization of China’s energy system as well as more synergistic pathways to address air pollution and global climate change simultaneously.

Infrastructure for China＇s Ecologically Balanced Civilization

China＇s green investment needs up to 2020 are ￥1.7 trillion-2.9 trillion CNY （$274 billion-468 billion USD） per year. Estimates of financing requirements are provided for multiple sectors, including susainable energy, infrastructure （including for environmental protection）, environmental remediation, industrial pollution control, energy and water efficiency, and green products. The context to China＇s green financing is discussed, covering urbanization, climate change, interactions between infrastructure sectors, and the transformation of industry. Much of the infrastructure financing will occur in cities, with a focus on equity, environmental protection, and quality of life under the National New-Type Urbanization Plan （2014-2020）. China has implemented many successful policies in the building sector, but there is still considerable scope for improvement in the energy efficiency of Chinese buildings. China is currently pursuing low-carbon growth strategies that are consistent with its overall environmental and quality-of-life objectives. Beyond 2020, China＇s future as an ecologically balanced civilization will rest on the implementation of a central infrastructure policy： China 2050 High Renewable Energy Penetration Scenario and Roadmap Study. As exemplified by the Circular Economy Development Strategy and Near-Term Action Plan, an essential part of China＇s green industrial transformation involves engineering systems that conserve materials, thereby reducing or even eliminating wastes. To better understand changes to China＇s economy under its green transformation and to unlock large potential sources of finance, it is necessary to undertake a fuller examination of all of China＇s infrastructure sectors, particularly freight rail infrastructure and ports. Large investments are required to clean up a legacy of environmental contamination of soil and groundwater and to reduce industrial pollution. Transformation of the power sector away from coal will avoid some industrial treatment costs. The contribution of engineers in planning, designing, and constructing China＇s new green infrastructure will be furthered by understanding the broad policy context and the interactions between land use, infrastructure, and environmental performance.

Framing climate strategy of the oil industry of China:A tailored approach to ecological modernization

China has announced its ambitious targets of attaining a carbon peak before 2030 and achieving carbon neutrality by 2060.Although China is a developing country,its oil sector plays a key role in carbon emissions and thus has a responsibility toward climate change.It is very important to understand the role of the oil industry of China in climate governance.This raises the following question:how have oil companies in China framed and tailored their climate strategies?By employing the concept of ecological modernization as a theoretical framework,this study observes the driving forces of climate policies,low-carbon energy,advanced technologies,and market mechanisms by collecting and analyzing reports published by three oil companies.The main findings are that state-owned oil companies in China have adopted the ideas and institutions of national climate strategies,low-carbon energy systems,and emerging financial and market tools.The analysis of the reports reveals that the main motives for the climate strategies of the companies are China’s administrative system,international climate cooperation,the transformation of the energy mix,and emerging market mechanisms.
