[en] The first step toward finding a solution to the problems with air pollution is the realization of a land survey map of polluters and a constant acquisition of data from periodical controls of emission of harmful materials, which will be carried out with a determined dynamic. Such a land survey map is not a project which should be finished within a strict time limit, but is intended to create all conditions for a periodical monitoring of emission of harmful materials from registered polluters in order to make a periodical, exact picture of the quantity of harmful materials, which are conveyed by polluters in certain city, a part of the state or the whole country.

[en] Nowadays, the human health is closely related to quality of indoor air. This article analyzes the main types of pollution to indoor air and their harms to human health, and on this basis, it sets forth the prevention measures comprehensively and proposes advices to normalize industry standards.

[en] Due to increasingly serious urban pollution, this paper proposes an environmental pollution prevention and control system in combination with Internet of things. The system transfers data through the Internet, which also utilizes sensor, pH sensor and smoke sensor to obtain environmental data. Besides, combined with the video data acquired through monitoring, the data are transferred to data center to analyze the haze pollution, water pollution and fire disaster in environment. According to the results, multi-purpose vehicles are mobilized to complete the tasks such as spraying water to relieve haze, water source purification and fire fighting in city environment. Experiments show that the environmental pollution prevention and control system designed in this paper can automatically complete the urban environmental pollution detection, prevention and control, which thus reduces human and material resources and improves the efficiency of pollution prevention and control. Therefore, it possesses greatly practical significance to the construction of smart city. (paper)

[en] This paper sums up the recent developments in concepts and methods being used to measure the impacts of cities on environmental sustainability. It differentiates between a dominant trend in research literature that concentrates on the accounting and allocation of greenhouse gas (GHG) emissions and energy use to cities, and a re-emergence of studies focusing on the direct and indirect urban material and resource flows. The availability of reliable data and standard protocols is greater in the GHG accounting field and continues to grow rapidly

[en] High energy consumption is a major feature of the logistics industry. Under the current low-carbon development requirements, the low carbon development of logistics is bound to be a new direction, and more scholars will turn their attention to low-carbon logistics. This paper presents a detailed introduction to low-carbon logistics from four aspects: the definition of low-carbon logistics, the influencing factors and Countermeasures of development, and the evaluation of carbon emission efficiency.

[en] Highlights: • We examine the effect of the U.S. Regional Greenhouse Gas Initiative (RGGI) on electricity flows. • Electricity imports in the regulated region increased after RGGI's establishment. • Results suggest emissions reductions in region are offset by increased emissions in other regions. This paper presents evidence that electricity influx to the U.S. Northeast increased after the introduction of the Regional Greenhouse Gas Initiative (RGGI), a carbon emissions abatement program. Electricity markets allow emissions reductions achieved in the region to be offset by increased emissions in other electricity-producing regions, as local generation is replaced with electricity imports. The empirical analysis is conducted using the synthetic control method. Results indicate that imports increased after RGGI's establishment in 2009—in which the increase predominantly occurred after the emission cap was reduced in 2014—which suggests that electricity production and carbon emissions increased outside RGGI.

[en] The author offers a detailed and illustrated panorama of the air pollution sources and effects. The study is realized at the individual scale with the indoor pollution and at a global scale with the consequences of the greenhouse effect gases. Added to classical pollutants, the book takes into account new pollutants (organic, nano particulates, biological) and the epidemiology. (A.L.B.)

[en] The TORR (total oil recovery and remediation) system utilizes a specially patented polymer material, similar to styrofoam, which is used to get rid of non-soluble hydrocarbons from water. An application in Fort Smith, Northwest Territories, is described where it was used to recover diesel oil, which had been seeping into the groundwater over a period of 20 years. About 100,000 gallons of heating oil had leached into the water; TORR removed the non-soluble hydrocarbons, while another piece of equipment removed the soluble portions. After treatment the water tested consistently at non-detectable levels and was clean enough to be discharged into the town's sewer system. The system is considered ideal for oil spills clean-up underground, onshore, or the open sea, but it also has many potentially useful applications in industrial and oilfield applications. Water used in steam injection and water floods to produce heavy oil and SAGD applications are some of the obvious ones that come to mind. Cleaning up the huge tailings ponds at the mining and processing of oil sands, and removing diluent from water that is used to thin out bitumen in pipelines so that it can be transported to processing plants, are other promising areas of application. Several field trials to test the effectiveness of the system in these type of applications are scheduled for the summer and fall of 2002

[en] The obstacles to bringing about consumer response to environmental dangers are particularly challenging for global problems like ozone depletion and the greenhouse effect. In this situation, there is the danger of what is commonly termed the tragedy of the commons, the ecological destruction that can occur from uncontrolled use of shared resources like the atmosphere. There is probably no country for which reductions in global warming provide an adequate economic incentive to reduce greenhouse gas emissions unilaterally, even though such action could yield substantial global benefits. From any one country's viewpoint, the costs of controlling emissions may exceed the benefits since, without international agreement, reductions achieved by one nation may be offset by another. Therefore, even though the entire world may be better off as a result of efforts to lower emissions, new economic incentives are necessary to lead the market to a socially efficient outcome. This paper describes the range of domestic and international policies that could be adopted to reduce emissions of greenhouse gases, and also discusses the results of modeling analyses of government actions that could reduce or increase such emissions

[en] Since the reform and opening up in the last century, many cities in China have entered the rapid stage of development, at the same time, the problem of urban water environment pollution has become increasingly prominent. Good water environment is the basic guarantee of the healthy and harmonious development of the city, therefore, people begin to invest a lot of energy on how to control the polluted water of the city reasonably and efficiently. In this paper, the present situation of water environment in most cities of our country is summarized, and the main technical measures and their advantages and disadvantages of urban polluted water treatment in the past are briefly analysed. And it further expounds on how to integrate landscape ecological construction technology into the treatment of urban polluted water in details in order to provide reference for the future urban water environment management.
