Connecting the dots: policy connections between Pacific Island shipping and global CO2and pollutant emission reduction

When vessels are berthed at ports, the air pollutants emitted by auxiliary engines will cause severe pollution to the ports and surrounding environments. In view of this situation, the author first summarizes the Chinese policies and policies of foreign countries on emission of air pollutants from vessels at berth, and then analyses the current status of and measures for control of air pollutant emission from vessels at berth. Secondly, the author analyses the environmental benefits of using shore power for better controlling air pollutant emission from vessels at berth, compares vessels using shore power with vessels using generated power in the energy conservation and emission reduction effects based on the fuel consumption rate of different auxiliary engines and current status of pollutant emission from power generation in China etc., analyses the current status of shore power application in China, estimates the energy conserved and emission reduced when shore power is used by vessels at berth. Thirdly, the author identifies the scale of electric energy replacement by, and environmental benefits of, shore power at ports in China. This paper delivers innovative approaches to the comparison between the effects of energy conservation and emission reduction based on fuel consumption rates of different auxiliary engines and estimation of conserved energy and reduced emission.

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.

Stability Results

An important topic in combustion research today is pollutant emission reduction. With the current demand for large amounts of economical, clean power, there is a need for research in both the increase of combustion performance and the reduction of emissions. Two methods of the so-called ‘passive’ flame controls are the use of premixing the air and fuel and the variation of the geometry of the flame. Both mechanisms offer the promise of increasing efficiency as well as reducing harmful emissions. However, the effect of these controls on the stability of the flame has not been fully studied. This paper will attempt to fill in some of this gap and will study the effects of elliptical burner geometry on premixed flames. The study will present stability results for circular and 4:1 aspect ratio elliptical burner geometry for a range of fuel mixtures of propane and hydrogen. The paper will also report the emission indices of CO and NO of the 40% by mass hydrogen in propane mixture. It was found that the 4:1 aspect ratio burner had reduced blow-out stability, produced a much shorter flame, and, in general, produced more carbon monoxide and less nitric oxide than a circular burner.

To relieve the pressure of the energy reservation and emission reduction, and to enhance the effect of the economy and environment profits, the report establishes an evaluating model based on the value of coal saving and the pollutant emission reduction value and the count of the electricity sale-purchase increment, which is various and cross-field. Through the model, the report evaluates the 4 cross-field projects by comparing the single coal-fired power transaction with the various, and analyses the outcome of the transaction in terms of the economy and environment. Finally coming to the conclusion, more economy and environment profits will be achieved when various power generation methods are used in power generation exchange.

High Pollution

Aiming at the harsh environmental situation at present, refinery and chemical enterprises in China are mostly of high energy consumption and high pollution enterprises, which have great emission reduction potential of atmospheric pollutants. Based on SO2and NOx produced by refinery and chemical enterprises, the emission reduction potential optimization model is established by using linear programming method, and combined environmental management policy about total amount control of atmospheric pollutants. Through the model results, the maximum pollutant emission reduction of SO2and NOx predicted through the model were 4810.69 and 1574.04 (tons), and the optimum technical schemes have been given, respectively. This model could provide not only the maximum emission reduction of the existing projects and enterprises, but also the decision support of emission reduction for refinery and chemical enterprises during "the 12thFive Year Plan".

Thermal power industry promotes economic development in a high speed, and it also brings the problem of resources and the environment. Building the evaluation index system of the thermal power plants’ ability of energy saving and emission reduction, we made use of the analytic hierarchy process to determine the weight. And the fuzzy comprehensive evaluation was applied to a thermal power plant in Shandong Province. We obtain following conclusion: the primer factor which confines its ability of energy conservation and emission reduction is pollutant emission. On this basis, we put forward the specific implementation measures from fiscal policy, tax policy and monetary policy, aim is to accelerate the development of China’s energy saving and emission reduction.
