China's Grain for Green Programme (GGP) is the largest ecological restoration programme ever implemented in a developing country, but the ecological effectiveness in its whole implementation region still remain uncertain. Based on the trend analysis of dynamics in ecosystem structure and service, we assessed the ecological effects before and after the implementation of the GGP in 1990–2010 by developing...
In this study the potential for further reduction in greenhouse gas emissions (GHG) of c-Si, multi-crystalline silicon (mc-Si) and CdTe photovoltaic (PV) systems are assessed to inform climate change mitigation in the UK. The amount of CO2 equivalent released in grams for each kWh of electricity over the lifetime of the PV system (gCO2-e/kWh) has been assessed using a model to predict the change in...
With the global "low-carbon economy" booming, energy conservation and emission reduction on tourism is a focus of global concern, because tourism is the important sector of carbon emission. Many tourism regions have proposed the measurements of energy conservation and emission reduction. Research on tourism emission reduction also began to rise. However, energy conservation and emission...
The carbon dioxide emissions of China have been high for a long time. According to the CO2 Emissions from Fuel Combustion Highlights 2010 Edition, as to 2008, total carbon dioxide emissions of China have surpassed the U.S. Building products is an important part of the national economy and construction industry is charged with the main task of the infrastructure in China. Construction activities is...
The paper selects China and Canada as samples respectively on behalf of developing countries and developed countries, according to the data from “the BP World Energy Statistics 2009” and the formula about carbon emissions from calculation handbook which in the UN's Intergovernmental Panel on Climate Change (IPCC) in 2006, the amount of total carbon emissions, per capita carbon emissions and carbon...
Acid rain can bring a lot of damage to the ecological environment of the earth and social economy of human. Studies show that acid rain is harmful to soil, waters, forest, buildings and scenic spots. It not only brings heavy economic loss, but also affects the survival and development of human severely. The SO2 in the atmosphere is the leading source of acid rain. Now People pay more and more attention...
Solar radiation data is essential to the work of energy planners, engineers and agricultural scientist. In this study, the solar radiation model was developed using the measurements from the 101 solar radiation observation stations in China. The average daily radiation on horizontal surfaces in 621 meteorological stations was estimated by the model with the sunshine hours and geographic information...
It is opinion that climate change on the planet is largely dependent on the increase of greenhouse gases in the atmosphere and that this effect is related largely to human activities that make CO2. Reducing the discharge of CO2 has therefore become a common objective of the international community, including China. There are various actions that are proposed for the reduction of the gas: increased...
China will more firmly embrace green and low-carbon development ideals and step up efforts in saving resources and protecting the ecological environment. Therefore, the green taxation policy is just part of a portfolio of possible policy changes. Under this background, this article summarizes many countries' green taxation policy, and explains the objective of polluter pays principle and the mechanism...
Based on reference literature, this paper use DEA Malmquist technology to establish the total factor index model considered the variable returns to scale for evaluating carbon emissions performance and analyzed the results. And then, based on the STIRPAT equation, the paper used provincial panel data to test the main factors of carbon emissions performance in China. All the results showed that: In...
As a kind of biomass resources, the corncob is widely applied in the product of furfural. At present, the yield of furfural has consumed half of the corncob product in China each year. The high pollution and high energy consumption are the choke points which restrict the development of furfural. In this paper, the wastewater and fume was investigated in detail. The major problem was the wastewater...
This paper presents life cycle fossil primary energy consumption (FPEC) and greenhouse gas (GHG) emission intensity of nine types of dominant secondary energy (SE) in China in 2008. Three major types of GHG (CO2, CH4 and N2O) are considered for GHG emissions intensity and then on-combustion CH4 leakage during the feedstock production sub-stage is included. It is found that: (1) the life cycle FPEC...
This paper presents coal consumption of electricity generation in China under different energy scenarios of the given long-term energy policies. Long Range Energy Alternatives Planning 2008(LEAP 2008) software is used to develop a simple model of electricity demand and to estimate gross coal consumption of electricity generation in China until 2030 under these scenarios. And, time-serial emission...
Energy-efficient renovation has been accepted widely as the best solution for upgrading existing residential buildings. In order to guide such real projects in China and maximize the benefits in energy, environmental and economic fields from the activities, in this article a methodology is developed for decision-makers to assist the design of energy-efficient renovation plan in the early stage of...
Ambient PM10 was sampled during September 17th, 2007 to September 23th, 2007 and during January 14th, 2008 to January 20th, 2008 at three sites (Tongshan animal hospital, Yellow River village and HuaiTa) in Xuzhou. The samples were analyzed for 16 metal elements (Na, K, Mg, Ca, Zn, Fe, Al, Si, Cu, Mn, Co, Pb, Cr, Ti, V and Ni), three anions, elemental carbon and organic carbon. Chemical mass balance...
The low carbon development assessment can provide valid information to support decision making in regional sustainable development. With the support of forest carbon sinks information simulated from remote sensing data, the low carbon development assessment index framework of Fujian Province, China was constructed. After indices weighting by the fuzzy analytic hierarchy process (FAHP), the low carbon...
Gray correlation analysis and improved IPAT model were used to analyzed industrial environmental impact in Jiangsu, china from 1999 to 2009. Empirical results are : a) all the main industrial pollutants have been controlled, especially the industrial solid wastes, except the total volume of industrial waste gas discharged; b) in spite of the eco-efficiency of industrial waste water grows faster than...
Based on 2003-2009 air pollution monitoring data in Chongqing city, weather characteristics of pollution events are investigated. Results show that the major pollutant is PM10,., which has a “Dual Peak and Dual Valley” diurnal fluctuation The pollution weather has obvious seasonal and continuity characteristics and these pollution events mainly occur from late-Autumn to next early spring with persistent...
Manufacturers are now facing common problems of environmental impact from the local society, green regulation, green product and factory operation in developing countries like China. Water, noise and air pollutants are significantly environmental issues from arise not intense environmentally consciously manufacturing. This paper presents to use integrated decision tools to assist stakeholder to determine...
Polycyclic aromatic hydrocarbons (PAHs) were determined in total suspended particles(TSP) sampled from 7 different typical cities in Shandong province, China. The sum of sixteen EPA priority PAHs concentrations ranged from 56.22 to 612.93 ng per cubic meter in heating season and from 7.18 to 127.79 ng per cubic meter in nonheating season in Shandong region. The levels of PAHs concentration background...
