Group 1 - The overall air quality in Shaanxi province improved in the first half of the year, with a national assessment index of 4.08, a year-on-year improvement of 2.9% [1] - The average number of good air quality days in the province was 134.7, with a good rate of 74.4%, showing a year-on-year improvement of 0.2 percentage points [1] - The top three cities for air quality in Shaanxi were Shangluo, Ankang, and Yan'an, with the Guanzhong area showing a comprehensive index of 4.48, improving by 4.7% year-on-year [1] Group 2 - Shaanxi's key industries have shown significant improvements in pollution control, with the province ranking 14th nationally in the number of new energy vehicles [2] - The clean transportation ratio in industries such as thermal power, steel, coal, and coking has increased to 72%, with a reduction of 2.26 million tons in coal consumption for thermal power units compared to the same period last year [2] - By the end of June, 82% of the steel industry's capacity in Shaanxi had completed ultra-low emission transformations [2]

Core Insights - The overall trend of ozone pollution in China has been initially controlled, stabilizing over the past three years [1] Group 1: Current Situation of Ozone Pollution - From January to May this year, the national ozone concentration was 140 micrograms per cubic meter, a year-on-year increase of 0.7% [1] - There were a total of 2,480 days with ozone exceeding standards, higher than the historical average for the same period [1] - Ozone pollution characteristics this year include: 1. Early onset of pollution, with 80 cities exceeding ozone standards as early as March 26, one month earlier than the average start time [1] 2. Widespread pollution, with over 100 cities exceeding ozone standards for five consecutive days from May 26 to 30 [1] 3. Severity of pollution is greater in the south compared to the north, attributed to higher temperatures and lower precipitation in southern regions [1] Group 2: Future Measures for Ozone Pollution Control - The Ministry of Ecology and Environment will enhance ozone pollution prevention through four main strategies: 1. Improve air quality monitoring networks and closely monitor the concentration changes of ozone and its precursors, volatile organic compounds, and nitrogen oxides [2] 2. Continue to investigate and rectify issues related to volatile organic compounds, with 5,912 enterprises inspected from January to April, uncovering 10,388 issues, and 9,530 issues rectified [2] 3. Promote ultra-low emission transformations in key industries, with over 80% of crude steel capacity undergoing such transformations by the end of May, along with significant projects in coking and cement industries [2] 4. Strengthen environmental regulation of motor vehicles, focusing on heavy-duty trucks and inspection agencies to combat excessive emissions and fraudulent practices [2]

Core Viewpoint - The article emphasizes the importance of reducing ozone pollution during the summer months by encouraging night-time refueling and promoting green travel methods to protect public health and improve air quality [1][2][3]. Group 1: Night-time Refueling Initiatives - Various cities in Henan province advocate for drivers to refuel at night (from 20:00 to 6:00) between May 1 and September 30, as lower temperatures reduce volatile organic compound (VOCs) emissions, thus decreasing ozone pollution [1][2][7][10][21]. - Gas stations are encouraged to implement night-time refueling discounts to attract customers and effectively manage daytime refueling traffic [5][10][21][23]. - The initiative aims to not only reduce environmental pollution but also provide economic benefits to consumers through discounts and promotions [1][5][10]. Group 2: Oil Unloading Adjustments - Gas stations are urged to adjust their oil unloading schedules to night-time hours (20:00 to 6:00) to minimize VOC emissions during high-temperature periods [3][8][12][19]. - Strict operational protocols are recommended to ensure the integrity of the unloading process, preventing gas leaks and further emissions [3][12][19]. Group 3: Promotion of Green Travel - Citizens are encouraged to adopt low-carbon travel methods, such as walking, cycling, or using public transport, particularly for short distances (1 km walking, 3 km cycling, 5 km public transport) [4][11][18]. - Recommendations include parking vehicles in shaded areas to reduce fuel evaporation and minimizing idling time to lower emissions [11][19][20].
