Eco-costs are a measure to indicate environmental burden of aproject or aproduct. This paper presents a practical applicationof Eco-costsModel in evaluating different emissions reduction measures on construction equipment.We propose acomparison model withthe input data of emission reduction percentageand Eco-costs of emissions. Then, six emissions reduction measures are chosen to develop detailed processes in using the comparison model.The study provides a guide in evaluating air pollution ofdifferent emissions reduction measures on construction equipment, which shows a theoretical foundation on selecting emissions reduction measures.

The rate of air pollution is becoming a cause for worldwide concern because of its substantial increase. Different sources like combustion of fuels, release of smoke from industries etc are responsible for the pollution of air. The construction industry is a major contributor to air pollution in the form of dust. Most of the activities involved in the completion of a construction project contribute to the generation of dust in one way or another. There are many sources of dust in a construction site like the use of construction equipment, transportation activities etc. the dust thus generated can ill effects as well. But, the problem of dust pollution is not addressed properly mainly because of the lack of awareness in this area. Proper identification of sources of dust in sites, its health impacts etc can help generate awareness and also help in implementing control measures. This can help reduce dust pollution on site. Here, a residential building site is taken for the case study. A questionnaire survey is conducted for the workers to identify the negative impacts construction dust has and also to determine the most common dust control measures employed in site. Keywords—air pollution, construction activities, construction equipment, questionnaire survey, dust control

On account of severe water pollution condition, this paper combines structure emissions reduction, engineering emissions reduction and management emissions reduction (namely SEM emissions reduction), builds an optimization model for total amount control of regional water pollution, and puts the above model into practice to validate its validity and reliability. According to the case study, the emission reduction of COD and NH3-N are 43.94 and 7.09 (104 tons), respectively. The optimal total costs of reduction is 36.89 (billion yuan), which decreases 7.47% than the existed recommended scheme (39.87 billion yuan). This method can be used for providing technical support and thus achieves the 12th Five-year goals of the environment protection plan more effectively.

Carbon footprinting of products and services is getting increasing attention due to the growing emphasis on carbon related policies in many countries. As a result, many enterprises are focusing on the design of green supply chains (GSCs) with research on supply chains (SCs) focused not only on cost efficiency, but also on its environmental consequences. The review presented in this paper focuses on the implications of carbon policies on SCs. The concept of content analysis is used to retrieve and analyze the information regarding drivers (carbon policies), actors (for example, manufacturers and retailers), methodologies (mathematical modeling techniques), decision-making contexts (such as, facility location and order quantity), and emission reduction opportunities. The review shows a lack of emissions analysis of SCs that face carbon policies in different countries. The research also focuses on the design of carbon policies for emissions reduction in different operating situations. Some possible research directions are also discussed at the end of this review.

Abstract. To comprehensively evaluate the effects of the recent “2+26” regional strategy for air quality improvement, we compared the variations in PM2.5 concentrations in Beijing during four pollution episodes with different emission-reduction strategies. The 2+26 strategy implemented in March 2018 led to a mean PM2.5 concentration 16.43 % lower than that during the pollution episode in March 2013, when no specific emission-reduction measures were in place. The same 2+26 strategy implemented in November 2017 led to a mean PM2.5 concentration 32.70 % lower than that during the pollution episode in November 2016, when local emission-reduction measures were implemented. The results suggested that the effects of the 2+26 regional emission-reduction measures on PM2.5 reductions were influenced by a diversity of factors and could differ significantly during specific pollution episodes. Furthermore, we found the proportions of sulfate ions decreased significantly, and nitrate ions were the dominant PM2.5 components during the two 2+26 orange alert periods. Meanwhile, the relative contribution of coal combustion to PM2.5 concentrations in Beijing during the pollution episodes in March 2013, November 2016, November 2017 and March 2018 was 40 %, 34 %, 28 % and 11 %, respectively, indicating that the recent “Coal to Gas” project and the contingent 2+26 strategy led to a dramatic decrease in coal combustion in the Beijing–Tianjin–Hebei region. On the other hand, the relative contribution of vehicle exhaust during the 2+26 orange alert periods in November 2017 and March 2018 reached 40 % and 54 %, respectively. The relative contribution of local emissions to PM2.5 concentrations in Beijing also varied significantly and ranged from 49.46 % to 89.35 % during the four pollution episodes. These results suggested that the 2+26 regional emission-reduction strategy should be implemented with red air pollution alerts during heavy pollution episodes to intentionally reduce the dominant contribution of vehicle exhausts to PM2.5 concentrations in Beijing, while specific emission-reduction measures should be implemented accordingly for different cities within the 2+26 framework.

This paper evaluates the real effects of pollution charges reform on [Formula: see text] emissions at the city level. Using the establishment of Comprehensive Work Plan for Energy Conservation and Emission Reduction (The Plan) in China as a quasi-natural experiment, our difference-in-differences estimation shows that: (1) increasing pollution charges has a significant and positive effect on controlling industrial waste [Formula: see text], and this relationship is robust to different specifications and alternative measures; (2) [Formula: see text] emissions can be reduced to achieve reduction targets by forcing companies to strengthen the degree of process production controls and end-of-pipe treatment; (3) eastern and western cities have a better pollution control effect than the other regions, and large cities have better emission reduction effects than smaller cities. Overall, this paper sorts out the evolution of China’s pollution charge policy, and reveals the mechanisms behind the real effects of pollution charges reform on [Formula: see text] emissions, thus providing timely implications for policymakers concerned with environmental protection.

Pollution Rights

To control growing environmental problems, the pollution rights trading (PRT) center was established in Jiaxing in 2007, and China officially joined the carbon emission reduction market (NCET) in 2011. Since power enterprises are the main participants in the NCET market and PRT market, the integrated effect of the NCET market and PRT market on power enterprise profit and the regional environment is one of the major issues that needs to be taken into consideration. Based on system dynamics (SD) theory, we propose an NCET-PRT simulation model for power enterprises in Chongqing. Through analyzing parameters of carbon trading price, free ratio, and emission trading prices, 12 different simulation scenarios are configured for sensitivity analysis. Based on the simulation results, the following observations can be obtained: (1) NCET and PRT can effectively promote the performance of enterprises’ carbon emissions reduction and regional pollutant emission reduction but will have a minor negative impact on the industrial economy at the same time; (2) The trading mechanism is interactive; if the carbon emissions trading (NCET) mechanism is implemented separately, the emission of pollutants will be reduced significantly. However, the implementation of pollution rights trading (PRT) alone cannot significantly reduce CO2 emissions; (3) At an appropriate level, NCET and PRT can be enhanced to achieve a maximum emissions reduction effect at a minimum economic cost.
