In recent years, under the dual-carbon task proposed by the state, the pressure of environmental protection governance has gradually increased, and the implementation of cleaner production can effectively reduce carbon emissions, what is cleaner production, that is, the use of advanced production processes and equipment, the use of clean energy and raw materials and other measures, from the source to reduce pollution, improve the efficiency of resource utilization, reduce or avoid the production and utilization of pollutants in the process of production and utilization, in order to reduce or eliminate the harm to human health and the environment.
So what do enterprises need to know about cleaner production?
Scope of cleaner production audits
The Cleaner Production Audit Measures stipulate:
Article 6 Cleaner production audit is divided into voluntary audit and mandatory audit.
Article 7 The State encourages enterprises to voluntarily carry out cleaner production audits. Enterprises other than those provided for in Article 8 of these Measures may voluntarily organize and implement cleaner production audits.
Article 8 Enterprises with any of the following circumstances shall carry out compulsory cleaner production audits:
(1) Where the discharge of pollutants exceeds the discharge standards provided by the state or localities, or although it does not exceed the discharge standards provided by the state or localities, it exceeds the total discharge control targets for key pollutants;
(2) Exceeding the energy consumption limit standard for unit products constitutes high energy consumption;
(3) Using toxic and harmful raw materials for production or discharging toxic and harmful substances in production.
Among them, toxic and harmful raw materials or substances include the following categories:
The first category, hazardous waste. This includes hazardous wastes included in the National Hazardous Waste Directory, as well as wastes with hazardous characteristics identified according to the hazardous waste identification standards and identification methods stipulated by the state.
The second category is highly toxic chemicals, chemicals listed in the Catalogue of Hazardous Chemicals for Key Environmental Management, and substances containing the above chemicals.
The third category contains heavy metals such as lead, mercury, cadmium, chromium and metalloid arsenic.
Category IV, substances listed in the Annex to the Stockholm Convention on Persistent Organic Pollutants.
The fifth category, other substances that are toxic and may pollute the environment.

4. Procedures for key enterprises to carry out cleaner production audits
For the cleaner production audit of key enterprises, after the list is first announced by the environmental protection department, a type of enterprise (double super) shall disclose the information in the local main media within one month, and within 45 working days after the list is published, the basic information of the audit plan, audit organization and personnel will be reported to the local environmental protection administrative department (the enterprise entrusting the intermediary agency to conduct the cleaner production audit should be within 45 working days after the list is published, The basic information of the audit agency and the materials that can prove the signing time of the cleaner production audit technical service contract and the performance period of the contract shall be reported to the local environmental protection administrative department). The cleaner production audit shall commence within two months of the publication of the list and shall be completed within one year of the publication of the list.
The second type of key enterprises should be audited at least once every five years. After the enterprise completes the cleaner production audit, it shall report the audit results to the competent administrative department of environmental protection of the local people's government at or above the county level where it is located, and at the same time copy it to the competent administrative department of environmental protection of the province, autonomous region, municipality directly under the Central Government, and the municipality with separate planning status, and the administrative department of development and reform (economy and trade) at the same level.
The competent administrative departments for environmental protection of each province, autonomous region, municipality directly under the Central Government, and cities separately listed in the plan shall organize or entrust relevant units to review and accept the results of the cleaner production audit of key enterprises.
5. Enterprises carry out cleaner production audit processes
Cleaner production audits are divided into seven phases: planning and organization, pre-audit, audit, generation and screening of programs, feasibility analysis, program implementation and continuous cleaner production.
The first stage, planning and organization. The focus of this phase is on forming an audit team, obtaining the support of the leadership, developing a work plan, and promoting cleaner production ideas. Establish an audit leadership team and formulate an audit work plan.
The second stage, pre-audit. Cleaner production potential was identified through the current situation survey. Determine the focus of the audit, propose a no-low fee plan, and improve the audit team. This phase of the programme is a process of extensive solicitation of comments and proposals.
The third stage, audit. Establish a material balance, further find the focus of the audit from a quantitative point of view, analyze the reasons, and propose a no-low-cost plan for the audit focus. Consider eight aspects: raw materials, process management, process technology, equipment, products, waste, employees and management.
The proposal of the program is also carried out from these eight perspectives. For example, process improvement, strengthening equipment maintenance, improving the post operation system, strengthening staff training, etc. Start implementing a no-low-cost program.
The fourth stage, the generation and screening of the programme. The list of specific schemes, according to the no low fee/high fee plan classification summary, screening the plan, continue to implement the no low fee plan and verify the implementation effect. This stage requires the completion of the mid-term audit report, and it is recommended that the mid-term audit report be improved in the first four stages.
Phase V, Feasibility Analysis. Evaluate the feasibility of the programme from three aspects: technical, economic and environmental, and form a summary of medium- and high-cost programmes.
Phase VI, programme implementation. Organize the implementation plan, summarize the implementation results of the no-low-cost program, verify the results of the medium- and high-cost program, and analyze the results of all the implemented programs.
The seventh stage is continuous cleaner production. Form a cleaner production management system. Cleaner production has become a long-term strategy of enterprises and integrated into various activities of enterprises.
These seven phases involve a total of 35 steps. In these links, the company leader is responsible for approval, cleaner production experts throughout the technical guidance and decision-making consultation. Industrial experts are responsible for guiding the analysis during the generation and implementation of the programme. Enterprise technicians are involved in the whole process. Finally achieve the goal of cleaner production: energy saving, consumption reduction and no efficiency gains.
6. What are the requirements of third-party audit agencies
