生态环境部：加强重点行业大气环境绩效分级管理

Core Viewpoint - The Ministry of Ecology and Environment is enhancing the management of air quality performance grading in key industries to promote green and low-carbon transformation and high-quality development [1][2]. Group 1: Performance Grading System - The performance grading system is a significant institutional innovation for air quality management and serves as a crucial tool for advancing green and low-carbon transformation in key industries [1][2]. - The draft guidance document has been released for public consultation, indicating a move towards more structured performance grading [1][2]. - The performance grading policy has received recognition from industry enterprises, with a steady increase in the number of A-grade enterprises, leading to improved overall governance and pollution reduction [1][2]. Group 2: Grading Criteria and Implementation - The current performance grading is based on the "Technical Guidelines for Emergency Emission Reduction Measures in Key Industries during Heavy Pollution Weather," which includes 39 key industries [2]. - The proposed grading system categorizes performance into four levels: A, B, C, and D, with A representing the highest standards [2][3]. - The grading assessment follows a "shortboard principle," where the lowest score among indicators determines the overall performance grade for enterprises involved in multiple key industries [3]. Group 3: Encouraging Innovation and Oversight - To encourage continuous innovation, the Ministry plans to select "exemplary enterprises" from A-grade companies that utilize internationally leading technologies with significant pollution reduction effects [6][7]. - A periodic review mechanism for advanced performance grades will be established to prevent complacency among rated enterprises [6][7]. - The draft also emphasizes the need for a differentiated management approach based on performance levels across various sectors, including finance, taxation, and regulatory measures [7].
