In 2020, is based on our country ICAO standards for carbon verification of civil airlines of the first year. Our company is the first to join the International Civil Aviation Organization(ICAO) International Aviation Carbon Offset and Emission Reduction Program (CORSIA) Verification Agency, the first batch of civil aviation flight activities carbon emission verification agencies registered with the Civil Aviation Administration of China. Participation in civil aviation carbon emissions verification work, and other domestic industry carbon verification requirements are different, civil aviation carbon verification is a brand-new work, which has the characteristics of large data processing and high data quality requirements., and affected by the epidemic, but also face the reality of time constraints.

In 2020, we signed an audit contract with a Chinese airline to provide civil aviation carbon verification services for 2019. The airline is the airline with the largest number of transport aircraft, the most developed route network and the largest annual passenger volume in China, and its fleet size and passenger traffic are among the highest in the world. , nearly 100 sorties flown in 2019 10,000 times, involving both aircraft wet lease and aircraft escrow operations, the composition of IT system is complex, and the verification technology is difficult. Our company sends professionals to form an audit team to audit the project. Because it is the first year of civil aviation carbon verification work, many work is started from scratch, in the face of difficulties, our companys audit team in the complex data, in a variety of materials to find proof, and strive to ensure the quality of data, the competent departments and customers have a satisfactory account.

Through a week-long audit, the audit team started with the airlines carbon emission system and compared it with the airlines internal production statistics system and external air traffic control data, and found that there were slight differences between the summary data of its carbon emission system and the airlines internal statistics and external air traffic control data. Through spot checks over1000 flight original documents, found that the airlines carbon emissions system calculation rules are unreasonable resulting in slight deviations in carbon emissions data. The audit team visited the statistics department, the operation command center, the IT department, the flight team, the ground service department, the finance department and other departments, and finally determined the emission data and formed a complete verification report.

The relevant suggestions on improving carbon emission management put forward by the audit team were recognized by the airline, which provided strong support for further improving the management of carbon dioxide emission data of civil aircraft. The quality of the report was affirmed by the Civil Aviation Administration and successfully passed the review of the Civil Aviation Administration. It has laid a good foundation for the enterprises carbon emission management in the future.

Energy-saving diagnosis is the process of finding problems according to the energy consumption status and energy utilization rate of each production node in the enterprise process and process, and using systematic methods to find out the root of the problem, predict the energy-saving potential, and propose specific management or technical measures.

In September 2020, our company carried out energy-saving diagnostic work for a pharmaceutical group. After receiving the task, our company will arrange special personnel to form a project team to conduct diagnostic requirements disclosure with the enterprise at the first time. Through communication, we will confirm that the enterprise currently has problems in energy management. We need to know the current energy management level of the enterprise in detail and help the enterprise to formulate energy management system documents. It is also necessary to fully understand the energy use status of enterprises, investigate the problems and weaknesses of enterprises in energy use, tap the potential of energy conservation, find the direction of energy conservation, and put forward practical energy-saving measures in order to achieve the diagnostic purpose of reducing energy consumption and production costs and improving the economic efficiency of enterprises.

Through the analysis of the enterprises energy consumption structure, the main process flow, the main energy supply equipment and the construction of the energy management system. It is identified that although the enterprise has applied some energy-saving technologies, its energy management needs to be further improved. It is recommended to gradually improve the energy management system, continuously improve, strengthen and improve the site energy management, and further improve the steam and water resources statistics and secondary measurement.

At the same time, through the analysis of the current energy consumption of enterprises, as well as an objective assessment of the situation of energy-saving technological transformation. Diagnosis of a number of energy-saving technological transformation measures that enterprises can implement, mainly (1) Replace the eliminated motors in the motors of the main energy-consuming equipment with high-efficiency motors;(2) Reforming the cooling water pump of the vacuum system in the extraction workshop and installing frequency conversion devices for it;(3) The air compressor equipment is frequently started and stopped with low loading rate, replaced with frequency conversion equipment, and integrated and networked control of stations and buildings;(4) Coal-fired boilers do not have economizer flue gas waste heat recovery devices, and economizer is added, recovery of boiler waste heat. Through the prediction and analysis of the energy saving amount of the above four energy-saving technological reforms, after the energy-saving transformation, the cost of energy utilization can be saved nearly 400000 yuan per year for the enterprise.

After receiving the energy-saving diagnosis report, the enterprise shall actively communicate with us about the energy-saving transformation. Organize the energy-saving technical transformation team to put forward the transformation proposal to our company for implementation. At present, the transformation project is being stepped up. Energy saving is expected to be good.

In 2020, a shipbuilding industry project was included in the local cleaner production mandatory audit unit, affected by the epidemic, business operations are more difficult, but in the environment of green and low-carbon development, environmental protection is still not taken lightly. In 2020, we will sign a cleaner production audit contract with our company, and both parties will jointly complete this cleaner production audit.

The project has three main features: (1) The scope covers the ship repair and the construction of offshore equipment and special engineering ships. The complex process, many environmental factors and scattered pollutant emission sources make the analysis of the current situation of the enterprises production and pollution discharge and the evaluation of cleaner production indicators become the main technical difficulties of the project. (2) The scale of the project is huge, which requires the planning and progress control of the project in the early stage, as well as a complete analysis of the project;(3) There are few clean production audit projects in the ship repair and construction industry, and there are even fewer precedents to follow, which makes it difficult to grasp the qualitative and quantitative audit of the project in such aspects as production and sewage links and pollution factor analysis, and the proposal of medium and high-cost schemes.

According to the characteristics of the enterprise, the project team, through various working methods such as organization planning, standard study, expert consultation, on-site residence and internal discussion, has made in-depth analysis of the customers production process and pollution control measures in the tight project period against the preparation requirements of the cleaner production audit report, and has put forward and implemented a number of targeted plans, for example: add steel plate pretreatment line VOCs purification device, welding fume purification, DSV hull coating process improvement, for the bow outer plate processing process changes. In the end, it has achieved remarkable results in reducing pollution and increasing efficiency, and completed an objective, comprehensive and detailed audit of the enterprise.

Finally, the enterprise successfully passed the acceptance organized by the Ecological Environment Bureau, and solved the needs of the enterprise in a very timely manner. At the same time through the clean production audit as the enterprise follow-up. The pre-conditions for projects such as "waste-free industrial park" provide a guarantee for the follow-up work.
