Recently, Chongqing issued the Action Plan for Gas Control in the Winter and Spring of 2026-2027 (hereinafter referred to as the Action Plan for Gas Control in the Spring of 2026-2027), which is clear from the date of issuance of the Plan to February 28, 2027. Focus on six special actions, namely, closing of key tasks, control of open-air incineration, reduction of fireworks and firecrackers, joint law enforcement and systematic assistance, response to heavily polluted weather, joint prevention and control of Sichuan and Chongqing, and peak staggering and emission reduction, to implement differentiated control, focus on improving the ability of fine particulate matter (PM) pollution prevention and disposal, and continuously improve regional air quality.
It is understood that under the influence of the super-strong El Nino event, the cold air activity in Chongqing this winter and next spring is weak, the meteorological diffusion conditions are generally unfavorable, the temperature inversion and high humidity weather occur frequently, and the risk of pollutant accumulation increases significantly. In addition, Chongqing is a mountainous basin and valley terrain, and the calm weather occurs frequently from November to February of the next year, which is the key window period for air pollution prevention and control. The head of the Atmospheric Department of the Municipal Bureau of Ecology and Environment said that the Plan adhered to the overall promotion of ecological environment protection and economic development, highlighted the orientation of precise policy implementation and classified management and control, minimized the impact on the production and operation of enterprises and the daily life of the masses, and promoted the unification of ecological, economic and social benefits. In terms of
industrial sources, we will promote key projects such as the elimination of coal-fired boilers, the improvement of organized emission control, the treatment of industrial waste gas and the deep treatment of waste incineration facilities, accelerate the integration and upgrading of the sintered brick and tile industry, and complete the environmental performance improvement and transformation of 50 enterprises within the year. In terms of
mobile sources, we will speed up the elimination and renewal of high-emission vehicles, plan to eliminate 15,000 diesel trucks with the fourth national emission standard, complete the sampling and testing of oil and gas recovery devices in 922 gas stations and 28 oil storage depots, and further increase the proportion of clean transportation of bulk goods in key industries in Wanzhou, Fuling and Nanan districts and counties.
To implement the comprehensive management and control of open-air incineration, the Work Plan for Zoning Management and Control of Open-air Incineration in Chongqing was
issued to refine the management and control measures in different regions and time periods: all open-air incineration activities are prohibited in the no-burning area, and orderly incineration is carried out in the restricted burning area according to the requirements of different time periods. We will improve the mechanism for collecting, storing and transporting incineration waste, and build a four-level coordinated collection, storage, transportation and disposal closed-loop system of "village-town (street) -district-enterprise". By the end of
November 2026, all kinds of catering operators will be urged to complete the cleaning and maintenance of cooking fume purification facilities. Standardize the layout of centralized environmental protection fumigation service points, and build efficient flue gas collection and purification facilities; insist on monthly maintenance of facilities during the critical period to ensure the stable operation of equipment.
Implement the action
of reducing fireworks and firecrackers, strictly control the source, and promote the reduction of sales. Each district and county, based on the actual situation of its jurisdiction, optimizes and expands the scope of fireworks and firecrackers prohibition, and clears the sales outlets in the prohibited areas according to law. All fireworks and firecrackers entering Chongqing will be included in the flow registration system, so as to achieve full input and traceability; priority should be given to the promotion of low-sulfur, low-smoke and low-residue environmental protection products, and high-risk and high-pollution products should be strictly prevented from flowing into the local market.
Deepening cross-regional joint efforts to crack down on illegal activities. Emergency management, public security, market supervision, transportation, ecological environment and other departments jointly set up special classes to crack down on illegal storage, transportation, sale of fireworks and firecrackers, as well as "one certificate for multiple transportation" and other illegal acts.
Strengthen publicity and guidance, and advocate civilized festivals. Carry out regular publicity by relying on experts' interpretation of popular science and warnings of typical cases; increase inspection efforts at important nodes such as New Year's Day, the Spring Festival and Glutinous Rice Balls for Lantern Festival, do a good job of on-site persuasion, and guide the masses to practice the new fashion of safe, green and civilized festivals.
Implement joint law enforcement and systematic assistance actions
to precisely carry out joint law enforcement. To formulate a special law enforcement implementation plan, integrate the clues handed over by superiors, mass letters and visits, on-site assistance and supervision, online monitoring and monitoring of pollution sources, supervision of electricity and energy consumption, mobile navigation monitoring and other multi-source data, and accurately lock in the objects of law enforcement inspection.
To implement the restriction and control of motor vehicles, the central urban area will fully implement the restriction measures for diesel trucks with the emission standards of the Fourth National Standard and below, and all districts and counties will synchronously implement the local restriction regulations, and strictly investigate and punish the violation of the ban. The departments of ecological environment, public security and transportation coordinate to carry out road inspection and household spot checks.
Compacting the responsibility of dust provention and control, strengthening the management and control of the whole process of construction site and dregs transportation, urging the implementation of dust control measures such as sprinkling, dust suppression and closed coverage; it is strictly prohibited to carry out high-frequency, unnecessary sprinkling and fog gun operations around the state-controlled air quality monitoring stations. Help the
district and county system. In view of the prominent pressure of air quality improvement and the shortcomings of annual target promotion, we should carry out technical assistance and guidance to consolidate the ability of air pollution control at the grass-roots level.
Implementing heavy pollution weather response actions
, improving the command and dispatch system of heavy pollution weather response, improving the level of 7-10 days pollution process trend research and 72-hour accurate early warning and forecasting, and implementing the joint consultation, joint forecasting and joint assessment mechanism of heavy pollution weather in Sichuan and Chongqing.
Strictly implement the Chongqing Heavy Pollution Weather Response Plan, and implement differentiated emission reduction measures based on performance classification. Dynamically update the emission reduction list of heavily polluted weather, and implement hierarchical management and control according to the environmental protection performance level of enterprises during the warning period: in principle, A-level enterprises will not take measures to stop production or limit production, minimize the disturbance to the production of B-level enterprises, guide enterprises to take the initiative to upgrade quality and strive for higher performance level, and realize the coordination of pollution control and emission reduction and enterprise development. Establish a list of exemptions for major projects at the municipal level, incorporate projects into the list management, and exempt emission reduction in accordance with regulations on the premise of implementing pollution prevention and control measures, so as to ensure the orderly progress of major projects. After the warning of
heavy pollution weather is activated, the construction site shall stop earthwork excavation, building demolition, spraying and painting and other operations according to the regulations, and prohibit the use of non-road mobile machinery with national emission standards of II and below; gas-related enterprises shall strictly implement the requirements of emission reduction list; open burning is prohibited in the whole area.
Scientific disposal of large-scale and continuous heavy pollution process. Focus on key industries and fields, strengthen communication and consultation between government and enterprises, implement dynamic regulation and control of production and transportation, guide enterprises to rationally adjust equipment maintenance cycle, and implement phased and differentiated emission reduction; strictly prohibit excessive control such as "one-size-fits-all" shutdown, production restriction and traffic restriction around state-controlled monitoring stations. Grasp the favorable meteorological conditions, make overall use of aircraft, ground rockets and anti-aircraft guns, and carry out three-dimensional artificial precipitation enhancement operations in a safe and standardized manner. Sichuan-Chongqing
joint prevention and control and peak-staggering emission reduction actions
will be implemented to deepen the joint prevention and control of air pollution in Sichuan and Chongqing, and joint law enforcement inspections will be carried out in adjacent areas with prominent impacts of industrial agglomeration and cross-border transmission of pollutants, so as to coordinate the handling of regional atmospheric problems and reduce the impact of cross-regional pollutant transmission.
Coordinate and standardize the management of prohibition and restriction of burning, strengthen information sharing between the two places, jointly promote the control of prohibition and restriction of burning areas, and curb the phenomenon of disorderly burning, overtime burning and excessive burning. Coordinate to organize peak staggering and emission reduction, guide cement manufacturing, sintered brick and tile, building stone processing and other industries to implement differentiated peak staggering production, and guide engineering projects to optimize construction timing according to the completion of enterprise environmental performance classification, ultra-low emission transformation and deep treatment.
