Description

Technical Field

[0001] This invention belongs to the field of carbon emission calculation technology, specifically relating to a carbon emission calculation and assessment method applicable to engineering geological exploration enterprises. Background Technology

[0002] Carbon emission calculations are crucial for promoting regional and industry-wide carbon reduction, improving carbon emission trading markets, and addressing climate change. Engineering surveying is the front end of engineering construction and the source of carbon reduction in the engineering construction industry. With the further acceleration of urbanization, the engineering surveying industry will also usher in further development opportunities, making carbon reduction by engineering surveying companies a current focus of attention.

[0003] my country has issued 24 industry-specific guidelines for greenhouse gas accounting methods and reporting, providing methods for industries such as power generation, power grids, and steel production. However, there are still blind spots in the carbon emission accounting methods for certain industry activities, and more new methods are needed to supplement them. For example, Chinese patent application number CN202110952292.9 invented a carbon emission accounting method during large-scale domestic sporting events, and Chinese patent application number CN202210852274.8 proposed a carbon emission accounting method and system based on construction equipment during the building construction phase.

[0004] The production and operation activities of engineering geological exploration enterprises consist of multiple independent exploration projects with complex production processes. Existing methods for calculating corporate carbon emissions have certain limitations. Different exploration projects operated by the same enterprise often have significantly different carbon emissions due to factors such as variations in terrain and geology, and differences in the technical skills of the operators. Calculating and assessing the carbon emissions of different exploration projects is beneficial for enterprises to comprehensively evaluate the carbon emission costs of their projects.

[0005] Establishing a carbon emission calculation and assessment method applicable to engineering geological exploration enterprises and forming a unified quantitative model is not only of practical significance for the management of carbon assets of engineering geological exploration enterprises, but also provides new ideas for carbon emission calculation and assessment of other enterprises. Summary of the Invention

[0006] The purpose of this invention is to establish a method for calculating and assessing carbon emissions of engineering geological exploration enterprises based on their production characteristics.

[0007] Based on a comprehensive analysis of carbon emission sources of engineering geological exploration enterprises and considering the characteristics of carbon emissions, this invention proposes a method for calculating and assessing carbon emissions of engineering geological exploration enterprises. This method is implemented through the following technical solution, with the specific steps as follows:

[0008] Step 1: Determine the carbon emission calculation boundaries and time range for engineering geological exploration enterprises, and track carbon emission sources within the boundaries;

[0009] Step 2: Select carbon emission factors and quantify the carbon emissions of each project;

[0010] Step 3: Summarize the carbon emissions of each project and calculate the carbon emissions of the engineering geological exploration company;

[0011] Step 4: Analyze the carbon emissions of each project and select the carbon emissions per unit of output to evaluate individual projects.

[0012] Step 1 specifically involves using a corporate entity or an independent unit deemed as a legal entity as the calculation boundary for carbon emissions of engineering geological exploration enterprises. The calculation timeframe for carbon emissions is selected as month, quarter, or year, depending on actual needs. To more accurately track carbon emission sources, the calculation boundary for carbon emissions of engineering geological exploration enterprises is refined to include: carbon emissions from a single project and office carbon emissions. Single project carbon emissions are the sum of carbon emissions from the project's preparation to completion. Office carbon emissions are the sum of carbon emissions generated by financial personnel, management personnel, and other personnel assisting in project implementation; these emissions are independent of the project and are therefore calculated separately.

[0013] Tracking carbon emission sources for individual projects includes: carbon emissions from the arrival of machinery and equipment, carbon emissions from drilling rigs, carbon emissions from other machinery and equipment, carbon emissions from sample delivery, carbon emissions from construction site management, and carbon emissions from vegetation destruction; tracking carbon emission sources for offices includes: carbon emissions from air conditioning energy consumption, and carbon emissions from lighting and other electrical equipment.

[0014] Carbon emissions from the transport of machinery and equipment to the construction site are the carbon emissions generated during the transport of machinery and equipment to the construction site. They are related to the transport distance, the mode of transport, and the weight of the transported machinery and equipment.

[0015] Carbon emissions from engineering drilling rigs are the carbon emissions generated by engineering drilling rigs during the drilling process. They are not only related to the power of the engineering drilling rig, but are also affected by external factors.

[0016] Other mechanical equipment carbon emissions refer to the carbon emissions generated by the use of other mechanical equipment in the project survey.

[0017] Carbon emissions from sample delivery are those generated during the process of transporting experimental samples to the laboratory, and they are related to the transportation distance, transportation method, and sample weight.

[0018] Carbon emissions from construction site management include those generated by on-site personnel transportation and accommodation.

[0019] Among them, carbon emissions from vegetation destruction are due to the impact on surrounding vegetation during project construction, resulting in a reduction in the amount of carbon sequestrated by vegetation. This part of the lost carbon emissions is called carbon emissions from vegetation destruction.

[0020] Step 2 specifically involves selecting carbon emission factors and quantifying the carbon emissions of each project. The selected carbon emission factors are mainly derived from national standards, authoritative research institutions, literature, and national statistical yearbooks.

[0044] In the formula: Q f Q7 represents the carbon emissions from the offices of engineering geological exploration companies within the calculation time frame; Q8 represents the carbon emissions from air conditioning energy consumption; and Q9 represents the carbon emissions from lighting and other electrical equipment.

[0045] Quantification of carbon emissions from air conditioning energy consumption

[0058] This invention proposes a method for calculating and assessing carbon emissions for engineering geological exploration enterprises. Based on a defined calculation boundary and time range, the method refines the calculation boundary to achieve more accurate carbon emission source tracking. Then, carbon emission factors are selected to quantify the carbon emissions of each project, thereby enabling the calculation and analysis of carbon emissions for engineering geological exploration enterprises. The method uses carbon emissions per unit of output value as the functional unit to assess the carbon emissions of the exploration enterprise. The beneficial effects of this invention are:

[0059] This invention quantifies the carbon emission calculation of engineering geological exploration enterprises from a microscopic perspective, filling the gap in carbon emission calculation methods for engineering geological exploration enterprises and helping exploration enterprises to better manage their own carbon emissions.

[0060] This invention enables engineering geological exploration companies to calculate carbon emissions based on the quantification of carbon emissions for individual projects. Quantifying carbon emissions for individual projects not only provides modular information for engineering geological exploration companies, but also offers new ideas for carbon emission calculation for other companies.

[0061] This invention uses the carbon emissions per unit of output value of a project as the functional unit for evaluation, which helps enterprises understand the carbon emissions of different projects, propose corresponding energy-saving measures, and achieve the enterprise's low-carbon goals.

[0062] Figure 1 This is a flowchart for carbon emission calculation and assessment by engineering geological exploration companies; Detailed Implementation

[0063] To more clearly illustrate the purpose, technical methods, and advantages of this invention, the invention will be further explained below in conjunction with the accompanying drawings and specific implementation examples.

[0064] Case study of carbon emission calculation and assessment of an engineering geological survey company.

[0065] Basic information of the engineering geological exploration company: In the first quarter of a certain year, four geological exploration projects were completed, involving a total of 23 pieces of machinery and equipment, including 17 engineering drilling rigs (all consuming diesel fuel) and 5 other pieces of machinery and equipment. There were 8 on-site management personnel and 51 construction workers. Machinery and equipment were transported to the site using 2-ton light diesel trucks, while samples were delivered using 2-ton light gasoline trucks. Personnel were transported by gasoline-powered passenger cars. The vegetation planted at the project sites consisted entirely of annual vines. The company's office has 2 air conditioners, 9 lighting fixtures, 6 computers, 1 printer, and 2 water dispensers; there are currently no other electrical appliances. Calculate the carbon emissions of this engineering geological exploration company in the first quarter as follows:

[0066] Step 1: Determine the carbon emission calculation boundaries and time range for engineering geological exploration companies, and track carbon emission sources within the boundaries.

[0067] Specifically, in calculating the carbon emissions of a certain engineering geological exploration company, the legal representative of the company is used as the calculation boundary, and the first quarter of the current year is used as the time frame for the calculation. To increase the granularity of the calculation and more accurately track carbon emission sources, the calculation boundary for the engineering geological exploration company is further refined to include carbon emissions from individual projects and carbon emissions from office use.

[0068] Carbon emissions from a single project include: carbon emissions from the entry of machinery and equipment, carbon emissions from the construction of engineering drilling rigs, carbon emissions from other machinery and equipment, carbon emissions from sample delivery, carbon emissions from construction site management, and carbon emissions from vegetation destruction; carbon emissions from the office include carbon emissions from air conditioning energy consumption, lighting, and other electrical equipment.

[0069] Step 2: Select carbon emission factors and quantify the carbon emissions of each project.

[0070] Due to the significant differences in production methods and energy structures across different regions and countries, national standards are given priority when selecting carbon emission factors, followed by authoritative research institutions and literature.

[0071] A certain engineering geological survey completed four projects in the first quarter. The specific carbon emission source quantification results for Project 1 are as follows.

[0072] Quantification of carbon emissions from the entry of machinery and equipment

[0073] Based on the statistics of the transportation distance and weight of the machinery and equipment entering the factory, and selecting a carbon emission factor of 0.286 kgCO2 / (t·km) per unit mass per unit distance for transporting machinery and equipment, the carbon emissions of the machinery and equipment entering the factory are as follows:

[0074]

[0075] Quantification of carbon emissions from engineering drilling rig construction

[0076] The diesel consumption of the drilling rig was collected, and the carbon emission factor of diesel was determined by taking values ​​from the "General Rules for Comprehensive Energy Consumption Calculation" and the "Guidelines for the Compilation of Provincial Greenhouse Gas Inventories (Trial)". The carbon emissions of the drilling rig during operation are as follows:

[0077]

[0078] Quantification of carbon emissions from other mechanical equipment

[0079] The energy consumption of other mechanical equipment in the statistical project is calculated. The energy consumed is gasoline. Based on the "General Rules for Calculating Comprehensive Energy Consumption" and the "Guidelines for Compiling Provincial Greenhouse Gas Inventories (Trial Implementation)," the carbon emission factor of gasoline is determined to be 2.9287 kgCO2 / kg. The carbon emissions of other mechanical equipment are as follows:

[0080] Carbon emissions from other machinery and equipment = 17.14 * 2.9287 = 50.22 (kg CO2)

[0081] Quantification of carbon emissions from sample delivery

[0082] Five groups of samples were surveyed, and the mean weight of each sample was obtained. The carbon emission factor per unit mass per unit distance was selected as 0.334 kgCO2 / (t·km). The carbon emissions from the samples were quantified as follows:

[0083]

[0084] Quantification of carbon emissions from construction site management

[0085] The energy consumption of on-site personnel during travel was statistically analyzed, and a carbon emission factor was selected based on the energy consumption method. This project uses gasoline as its energy consumption, and the carbon emission factor for gasoline was selected as 2.9287 kgCO2 / kg. The number of overnight guests, the number of nights spent staying, and relevant information on personnel activities during their stay were also collected. The carbon emission per person per night was determined to be 2.5 kgCO2. The quantification of carbon emissions from construction site management is as follows:

[0086] On-site personnel and traffic carbon emissions = 53.64 * 2.9287 = 157.095 kg CO2

[0087] Carbon emissions from on-site personnel accommodation = 11 * 2.5 * 12 = 330 kg CO2

[0088] Carbon emissions from construction site management = 157.095 + 300 = 487.10 kg CO2

[0089] Quantification of carbon emissions from vegetation destruction

[0090] The area of ​​vegetation destruction and planting methods were statistically analyzed. The CO2 fixation per unit area of ​​annual vines, low-grass flowerbeds, or low-stemmed wild grassland over 40 years was estimated at 14 kg / m². 2 The carbon emissions from vegetation destruction are quantified as follows:

[0091] Carbon emissions from vegetation destruction = 25 * 14 kg / m³ 2 = 350 (kg CO2)

[0092] The carbon emission calculation process for the other three projects is as described above and will not be repeated here. The specific calculation results for the four projects are as follows:

[0093]

[0094] Quantification of carbon emissions from air conditioning energy consumption

[0095] Based on the statistical analysis of office air conditioning equipment parameters and operating time, and using an electricity emission factor of 0.5896 kgCO2 / (kw·h) for this case study, the carbon emissions from air conditioning energy consumption are quantified as follows:

[0096] Carbon emissions from air conditioning energy consumption = 0.04w * 8 * 20 * 2 * 0.5896 = 7.55kgCO2

[0097] Quantification of carbon emissions from lighting and other electrical equipment

[0098] Carbon emissions from lighting and other electrical equipment

[0099] =9*0.01*82*4*0.5896+2*0.3*82*0.5896+1*0.5896*0.8*82*0.3=58.02kgCO2

[0100] Step 3: Summarize the carbon emissions of each project and calculate the carbon emissions of the engineering geological exploration company.

[0101] Based on the above quantification of carbon emissions for each project, the carbon emissions of each individual project are calculated. The carbon emissions of the engineering geological exploration company are calculated as follows: total carbon emissions of the project + carbon emissions of the office.

[0102] Calculation of carbon emissions for a single project:

[0103] Total carbon emissions from all projects = Project 1 + Project 2 + Project 3 + Project 4 = 11168.07 kg CO2

[0104] Office carbon emissions calculation: Office carbon emissions = carbon emissions from air conditioning + carbon emissions from lighting and other electrical equipment = 65.57 kg CO2

[0105] Carbon emissions of engineering geological survey enterprises: Total carbon emissions of projects + Carbon emissions from offices = 11233.64 kg CO2

[0106] Step 4: Analyze the carbon emissions of each project and compare the carbon emissions per unit of output of different projects to comprehensively evaluate the carbon emission costs of different projects.
