Description

Technical Field

[0001] The present invention relates to the field of pollution reduction and carbon reduction effect assessment, and in particular to a pollution reduction and carbon reduction effect assessment and analysis method for port terminals. Background Art

[0002] As the global climate change issue becomes increasingly prominent, carbon neutrality has become a common goal for governments and enterprises around the world, and "dual carbon" has become increasingly eye-catching. As an important transportation hub and logistics distribution center, port terminals are important links in trade, but their emissions have an impact on the environment that cannot be ignored. Therefore, the construction of green ports is particularly important. Green ports include energy conservation and emission reduction, resource recycling, ecological protection and other aspects, and their characteristics include environmental protection, high efficiency, and sustainable development.

[0003] In the study of the creation and assignment of low-carbon port evaluation index system, Chen Rui et al., in view of the lack of low-carbon port evaluation standards, took green, energy-saving, carbon reduction and pollution reduction as the basic starting point, based on the PSR model, and used the analytic hierarchy process and Delphi method to create an index system for low-carbon port evaluation; it provides an evaluation basis for the pollution reduction and carbon reduction evaluation in the implementation process of green port construction, but the method of assigning the weights and judgment criteria of the low-carbon port evaluation index proposed by them is a combination of quantitative and qualitative indicators, which is subjective and cannot achieve accurate quantitative evaluation of the pollution reduction and carbon reduction effects of green port terminals after the implementation of relevant construction measures. To this end, we propose a pollution reduction and carbon reduction effect evaluation and analysis method for port terminals. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 The present invention discloses a process for a pollution reduction and carbon reduction effect evaluation and analysis method for a port terminal. DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with specific implementation methods, wherein the accompanying drawings are only used for exemplary descriptions and represent only schematic diagrams rather than actual drawings, and should not be understood as limiting the present invention. In order to better illustrate the specific implementation methods of the present invention, some parts of the accompanying drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0034] Example 1

[0035] The specific implementation process of the technical solution of the present invention for evaluating and analyzing the pollution reduction and carbon reduction effects of port terminals includes the following steps:

[0036] Step 1: Classify the pollution reduction and carbon reduction effect evaluation indicators into two categories: air quality indicators and carbon emission indicators;

[0037] Among them, for air quality indicators, the concentration of major polluting gases in the atmosphere can be used as an evaluation indicator, wherein the polluting gases may include sulfur dioxide concentration, sulfur monoxide concentration, nitric oxide concentration, nitrogen dioxide concentration, PM2.5 concentration, carbon monoxide concentration, volatile organic compound (such as benzene, hydrocarbons, formaldehyde) concentration and photochemical oxide (such as ozone) concentration, etc.;

[0038] For carbon emission indicators, since the total amount of carbon emissions varies greatly depending on the size of the port, the carbon emission intensity index per unit throughput is used for evaluation; considering the consistency of the indicator system with the local assessment system, in order to ensure the completion of the carbon reduction and emission reduction target indicators, the carbon emission reduction progress indicator is selected. It mainly includes the following indicator types:

[0039] 1) Carbon emission intensity of ports

[0040] The port carbon emission intensity is the ratio of the total port carbon emissions to the port throughput, which is a negative indicator. The benchmark value is determined according to JTS / T 105-4-2020 "Green Port Grade Evaluation Guidelines". Specifically, the benchmark value for specialized container terminals is 2.44t CO2 / 10,000t, and the benchmark value for specialized dry bulk terminals is 1.04t CO2 / 10,000t.

[0041] 2) Progress in reducing carbon emission intensity in the port area

[0042] The progress of reducing the carbon emission intensity of the port refers to the degree of decrease in the carbon emission intensity of the port area compared with the previous year. The calculation formula is:

[0043]

[0044] In the formula, R D is the reduction degree of port carbon emission intensity; C t is the carbon emission intensity value during this testing period; C e is the carbon emission intensity value in the previous detection cycle;

[0045] Step 2: According to relevant standards, industry development plans, management regulations and historical statistics of the port terminal to be evaluated, obtain the baseline value Rv of the i-th air quality index and the j-th carbon emission index of the port terminal to be evaluated at the current time t i and Rv j and real-time value Tv i and TV j , where i = 1, 2, ..., n; j = 1, 2, ...,; n is the number of air quality indicators; m is the number of carbon emission indicators;

[0046] It should be noted that the benchmark value of the port terminal carbon emission index is the carbon emission per unit cargo throughput or per unit output value generated by various activities in the port. The determination of the benchmark value should be based on the specific conditions of the port and the regional climate characteristics. Among them, the calculation of the existing carbon emission benchmark value usually involves the following aspects:

[0047] Carbon emissions per unit of cargo throughput: Calculate the carbon emissions generated per unit of cargo throughput;

[0048] Carbon emissions per unit of output value: Calculate the carbon emissions generated per unit of output value.

[0049] Comparison of carbon emission benchmark values ​​of different ports The carbon emission benchmark values ​​of different ports may vary due to factors such as geographical location, climate conditions, and operating mode. The carbon emission benchmark values ​​of coastal ports and inland ports may differ. The specific values ​​need to be calculated and adjusted according to the actual conditions of each port.

[0056] when , it is determined that at the current time t, the pollution reduction and carbon reduction effect level of the port terminal to be evaluated is unqualified.

[0057] It should be noted that for the first evaluation threshold The setting can be determined according to the mean method. For example, based on the average value of several ports and terminals with similar geographical locations, climatic conditions, and operating modes, the first evaluation factor of each port and terminal and its benchmark value are calculated respectively, and then the average or weighted value of all the calculated first evaluation factors is taken as the first evaluation threshold of the current port and terminal to be evaluated. In addition, port and terminal operators can also set their own thresholds based on their future plans. By setting a higher threshold, they can constrain their own business operations and promote the development of high-quality port operations.
