What are the priorities for coordinated control of air pollutants and greenhouse gases?
On January 30, the Ministry of Ecology and Environment (MEE) issued the Technical Guidelines for the Compilation of Emissions Inventory of Air Pollutants and Greenhouse Gases (Trial) (hereinafter referred to as the "Technical Guidelines").
Pilot projects will be carried out in key regional cities such as Beijing-Tianjin-Hebei and surrounding areas
It is understood that the "Technical Guide" will be published in:Beijing-Tianjin-Hebei and surrounding areas, Yangtze River Delta region, Fenwei Plain and other key regional citiesCarry out pilot projects, form a standardized and business-oriented integration list, and update it dynamically on a regular basis.
The integrated emission inventory of air pollutants and greenhouse gases refers to the collection of emission data formed by summarizing the details of air pollutants and greenhouse gas emissions source by source in a certain time span and spatial area, according to the consistent emission source classification and grading system, the unified emission calculation method, and the common activity level data information.
The "Technical Guidelines" issued for the first time fully connect the existing emission accounting system, refine the classification and grading system of emission sources, stipulate the procedures for compiling the inventory of air pollutants and greenhouse gas fusion, and clarify the technical methods and whole-process quality control of the integrated emission inventory of air pollutants and greenhouse gases from various emission sources such as power and heat sources, industrial sources, mobile sources, oil storage, transportation and marketing, domestic sources, agricultural sources, and waste treatment sources.
The Technical Guidelines can support the formulation of air pollution prevention and control policies and the evaluation of effects
It is understood that the "Technical Guidelines" are suitable for the compilation of anthropogenic sources of air pollutants and greenhouse gas emission inventories at different spatial and temporal scales, to support the identification of synergistic targets for pollution reduction and carbon reduction, path optimization, policy formulation and effect evaluation, etc., and can also support the formulation and evaluation of air pollution prevention and control policies, air quality forecasting and early warning, and heavy pollution weather response;
The Technical Guidelines are not applicable to carbon market trading, assessment of responsibility for greenhouse gas emission targets, and international compliance with climate change agreements.
The scope of accounting for the Technical Guidance includes homologous emissions of air pollutants, carbon dioxide, methane, nitrous oxide and hydrofluorocarbons.
How do localities compile relevant integration lists?
In accordance with the requirements of the "Technical Guidelines", all localities should adhere to scientific norms. In accordance with the classification and grading system of emission sources and the calculation method of emissions detailed in this guideline, all localities shall obtain complete and standardized activity level data, reasonably determine emission coefficients, and strictly control the quality of the whole process to ensure the consistency, comparability and authority of inventory data。
Adhere to categorical guidance. All localities should combine the characteristics of local emission sources, management needs and work foundations, and select appropriate methods for compiling integrated inventories. Encourage qualified regions to choose calculation methods and localized parameters that can more accurately quantify emission characteristics, and improve the accuracy and spatiotemporal accuracy of inventories.
Adhere to unified cohesion. Unify and refine the types of emission sources, comprehensively connect technical methods and activity level data such as emission source statistics, pollutant discharge permits, greenhouse gas emission accounting for key industries and enterprises, and greenhouse gas emission inventories at all levels, and make full use of statistical data, departmental data, and big data on social activities to carry out the compilation of integrated inventories.
On December 28, 2023, Huang Runqiu, Minister of Ecology and Environment, presided over an executive meeting of the Ministry to review and approve the Technical Guidelines in principle.
The meeting pointed out that the application of the integrated emission inventory of air pollutants and greenhouse gases can effectively identify the key areas, key industries and key links of the coordinated control of air pollutants and greenhouse gases, and achieve the "five precisions" of problems, time, regions, objects and measures, which is the basic work to implement the synergy of pollution reduction and carbon reduction.
The meeting made it clear that after the issuance and implementation of the technical guidelines, relevant training should be conscientiously organized, and the construction of the talent team for the compilation of the integrated list should be strengthened, so as to provide technical support for the compilation of the list. Relevant departments should actively cooperate, strengthen data sharing, and promptly improve problems when they are discovered.
