Group 1 - During the "14th Five-Year Plan" period, the Ministry of Ecology and Environment, along with relevant departments and local governments, implemented 24,000 ecological environment governance projects, resulting in a significant reduction in the total emissions of major pollutants such as nitrogen oxides, volatile organic compounds, chemical oxygen demand, and ammonia nitrogen [1] - The reduction in nitrogen oxides and volatile organic compounds reached approximately 210,000 tons and 220,000 tons respectively, with the elimination of outdated production capacity including over 120 million tons of step-type sintering machine capacity and over 68 million tons of 4.3-meter and below coke oven capacity [1] - Urban environmental infrastructure construction has seen significant improvements, with cumulative reductions of approximately 3.2 million tons in chemical oxygen demand and 350,000 tons in ammonia nitrogen emissions through sewage treatment projects [1] Group 2 - A total of 124 major projects for soil pollution source control were implemented during the "14th Five-Year Plan," managing the leakage risk of 55 million tons of toxic and harmful substances annually [2] - The capacity for centralized treatment of hazardous waste reached 220 million tons per year, a 60% increase compared to 2020 [2] - The Ministry of Ecology and Environment plans to focus on strategic and leading major projects in areas such as air, water, and soil protection, solid waste and new pollutant management, ecosystem optimization, and climate change response for the "15th Five-Year Plan" [2]

Core Viewpoint - The air pollution situation in the province has improved, leading to a downgrade of the heavy pollution weather warning from orange to yellow, effective from January 25 at 0:00 [1] Group 1: Voluntary Pollution Reduction Measures - Promotion of green living practices, including maintaining air conditioning settings above 26°C in summer and below 18°C in winter, and keeping doors and windows closed during operation [1] - Encouragement of green transportation methods, such as using public transport or electric vehicles, and reducing idling time for vehicles [1] - Advocacy for green consumption by minimizing the use of solvent-based materials that emit volatile organic compounds [1] - Utilization of external electricity sources and prioritizing low coal consumption power generation while ensuring regional power balance [1] - Stopping the use of non-compliant fuel machinery at construction sites and industrial parks, except for emergency operations [1] - Implementation of artificial weather modification as needed [1] Group 2: Mandatory Pollution Reduction Measures - Industrial enterprises included in the emergency reduction list must implement yellow warning (Level III) response measures, including planned production cuts or shutdowns while ensuring safety [2] - Key enterprises emitting volatile organic compounds must halt all parking and maintenance operations that release emissions [3] - Prohibition of diesel trucks meeting National IV and lower emission standards in urban areas, with exceptions for special and hazardous materials vehicles [4] - Compliance with Long Triangle shipping emission control requirements, ensuring maximum use of shore power while docked [5] - Suspension of outdoor operations at sand and stone factories, and halting various construction activities that may generate dust [6] - Stopping operations of vehicles transporting bulk materials that do not meet emission standards, with exceptions for compliant vehicles [6] - Implementation of dust control measures at construction sites and exposed areas, including increased cleaning frequency and watering to reduce dust [6] - Enhanced frequency of inspections on major air pollution sources, including industrial enterprises and construction sites [7]
