[0027] An industrial park pollution reduction and carbon reduction synergistic coupling assessment system includes: The target progress tracking and evaluation module tracks and evaluates the completion of the park's superior plans or annual assessment indicators.
[0028] The evaluation of the pollution reduction and carbon reduction synergy index for industrial parks combines key factors such as economic development and industrial structure related to greenhouse gas and pollutant emission reduction performance to construct a synergy index for pollution reduction and carbon reduction in industrial parks. It provides a quantitative assessment of the overall pollution reduction and carbon reduction performance of the parks, supports data visualization, provides detailed synergy index analysis reports and automatically generated analysis reports, and supports data export and sharing.
[0029] The pollution reduction and carbon reduction technology assessment module evaluates carbon emissions, pollutant emissions, and the synergistic effect of pollution reduction and carbon reduction.
[0030] like Figure 1 As shown, a method for assessing pollution reduction and carbon reduction in industrial parks. The method includes: 1. Target progress tracking and evaluation (1) Energy dual control target (1.1) Energy intensity control target: The energy intensity control target of the park is usually set in the form of a percentage, which refers to the percentage reduction in energy consumption per unit of industrial added value.
[0031] The accounting model is as follows: Energy intensity: Comprehensive energy consumption per unit of industrial added value (tons of standard coal / 10,000 yuan) = Total comprehensive energy consumption of industry (tons of standard coal) / Industrial added value (10,000 yuan) For example: If the statistical time point is 2024, the total target percentage for 2024 = the target percentage entered by the park itself (which is manually entered).
[0032] Scenario 1: If the energy consumption intensity at the statistical point in 2024 is greater than the energy consumption intensity at the base period in 2023, then the progress will be treated as 0.
[0033] At this point, 2024 is complete. *100% (Add a negative sign before the formula to indicate a negative value) Scenario 2: If the energy consumption intensity at the statistical point in 2024 is less than the energy consumption intensity at the base period in 2023. Therefore, the energy consumption intensity for 2024 is calculated as: |Energy consumption intensity at a certain statistical point in 2024 - Energy consumption intensity in 2023| / Energy consumption intensity in 2023 (take the absolute value, which is positive). At this point, the progress of the 2024 energy intensity target = 2024 completed / 2024 total target Scenario 3: If the energy consumption intensity at the statistical point in 2024 equals the energy consumption intensity at the base period in 2023. Therefore, 2024 completed = 0, progress target = 0. The inputs are: manually entered total target value, base period total energy consumption, base period industrial added value, total energy consumption at the statistical time point, and industrial added value at the statistical time point. The output value is: to display the progress value of energy consumption intensity control target.
[0034] (1.2) Total energy consumption control target The total energy consumption control target of the park is usually expressed in terms of quantity, which refers to the control of the total energy consumption of various sectors of the national economy and households within a certain region within a certain period.
[0035] Accounting model: For example: Suppose the statistical time point is 2024. Completed in 2024 = Total energy consumption at a certain statistical point in 2024 2024 Overall Target = Target Value for 2024 Input by the Park Itself If the completed value equals the total target value, then set the total energy consumption control target progress to 100%, and the remaining emission reduction target to 0. If the completed value is less than the total target value, then set the total energy consumption control target progress to 100%, and the remaining emission reduction to 0. If the completed value is greater than the total target value, then the total energy consumption control target progress is calculated as: Total Target Value / Completed Value. The remaining emission reduction is calculated as: Completed Value - Total Target Value. Input values are: consumed amount and total target amount. The output value is: to display the progress value of the total energy consumption control target.
[0036] (2) Dual carbon control targets (2.1) Carbon emission intensity control target The carbon emission intensity control target for industrial parks is usually set as a percentage, which refers to the percentage reduction in carbon emissions per unit of industrial added value.
[0037] Accounting model Carbon emission intensity: Carbon emissions per unit of industrial added value = Total carbon emissions / Industrial added value For example: If the statistical time point is 2024, the total target percentage for 2024 = the target percentage entered by the park itself (which is manually entered).
[0038] Scenario 1: If the carbon emission intensity at the statistical point in 2024 is greater than the carbon emission intensity at the base period in 2023, then the progress will be treated as 0.
[0039] at this time, 2024 is complete = — *100% Scenario 2: If the carbon emission intensity at the 2024 statistical point in time is less than the carbon emission intensity at the base period in 2023. Therefore, the carbon emission intensity for 2024 is calculated as: |Carbon emission intensity at a certain statistical point in 2024 - Carbon emission intensity in 2023| / Carbon emission intensity in 2023 (take the absolute value, which is positive). At this point, the progress towards the 2024 carbon intensity target = (2024 completed / 2024 total target) Scenario 3: If the carbon emission intensity at the 2024 statistical point in time equals the carbon emission intensity at the base period in 2023. Therefore, 2024 completed = 0, progress target = 0.
[0040] Input values are: manually entered total target value, base period total carbon emissions, base period industrial added value, total carbon emissions at the statistical time point, and industrial added value at the statistical time point. The output value is: to display the progress value of the carbon emission intensity control target.
[0041] (2.2) Total carbon emission control targets The total carbon emission control target for the industrial park is usually expressed in terms of quantity.
[0042] Accounting model: For example: the statistical time point is 2024. Completed in 2024 = Total carbon emissions at a certain statistical point in 2024 2024 Total Target = Target Amount Input by the Park Itself for 2024 If the completed value equals the total target value, then set the total energy consumption control target progress to 100%, and the remaining emission reduction target to 0. If the completed value is less than the total target value, then set the total energy consumption control target progress to 100%, and the remaining emission reduction to 0. If the completed value is greater than the total target value, then calculate the total energy consumption control target progress = total target value / completed value, and the remaining emission reduction amount = completed value - total target value.
[0043] Input values are: Emissions already emitted, Total target amount The output values are: the progress bar value of the total carbon emission control target and the amount of emission reduction still needed.
[0044] 3. Evaluation of the Collaborative Index for Pollution Reduction and Carbon Reduction in Industrial Parks By combining key factors such as economic development and industrial structure related to greenhouse gas and pollutant emission reduction performance, a collaborative index for pollution reduction and carbon reduction in industrial parks is constructed. This index provides a quantitative assessment of the overall pollution reduction and carbon reduction performance of the parks, supports data visualization, provides detailed collaborative index analysis reports and automatically generates analysis reports, and supports data export and sharing.
