[0002] The entire life cycle of tea mainly includes six links: planting, processing, packaging, transportation, consumption and disposal. Since tea itself has the dual attributes of agricultural products and food, compared with crops such as grains and fruits, the special processing links make the accounting of its carbon footprint flexible and changeable. At present, there are few studies on the carbon emission accounting of tea throughout its life cycle in China. Compared with crops such as rice and corn, its carbon emission accounting not only lacks a unified accounting standard, but also lacks the measurement of carbon emission reference values ​​in the actual production of tea. Therefore, although relevant studies also cover the carbon emission accounting of some tea types throughout their life cycle, these studies not only have different accounting standards, but also the relevant reference values ​​used for calculation are not highly matched with the actual production and consumption of tea. These problems will reduce the accuracy of carbon footprint accounting of tea throughout its life cycle. Summary of the invention

[0018] The purpose of this application is to provide a tea carbon footprint accounting method, system and medium based on the entire life cycle, which improves the accuracy of carbon footprint accounting for the entire life cycle of tea and facilitates tea merchants to flexibly adjust tea production strategies based on the calculation results to better achieve carbon emission balance.

[0019] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1 As shown, this embodiment provides a method for calculating the carbon footprint of tea based on the entire life cycle, and the method for calculating the carbon footprint of tea based on the entire life cycle is specifically as follows.

[0021] Step S1: Determine the system boundary of the entire life cycle of tea.

[0022] In this embodiment, the system boundaries include six links: planting, processing, packaging, transportation, consumption and disposal.

[0023] Step S2: Determine the carbon emission projects in each link of the system boundary and the carbon emission sources corresponding to the carbon emission projects, and collect relevant information of the carbon emission projects.

[0024] The carbon emission items in the planting stage in this embodiment include: carbon emissions caused by fertilizers applied to tea trees in the upstream production process (the corresponding carbon emission source is the fertilizers applied to tea trees, and its related information includes: the total amount of fertilizers used and the average annual amount of fertilizers used during tea tree planting, etc.), nitrous oxide emissions generated in tea gardens during tea tree planting (the corresponding carbon emission source is nitrous oxide, and its related information is the emission of nitrous oxide in tea gardens, and it is necessary to regularly go to tea gardens to take samples using static boxes and other equipment), carbon emissions caused by energy consumption during tea tree pruning and picking (the corresponding carbon emission sources are different energy sources such as manpower, diesel or gasoline, and electricity, and its related information includes: tea tree pruning and picking methods and the names of equipment involved in the process, work efficiency and energy types used, etc.), and carbon fixed by photosynthesis during tea tree planting (the corresponding carbon emission source is the external environment, and its related information includes: the age of tea trees and root-to-crown ratio, the sum of aboveground and underground biomass of tea trees, the actual picking time of tea trees, all living matter in the aboveground part of tea trees, the planting area of ​​tea gardens, the average annual yield of tea, the geographical location of tea gardens, etc.).

[0025] The carbon emission items in the processing stage are the carbon emissions caused by the energy consumption in the process of tea processing. The corresponding carbon emission source is electricity. The relevant information includes: the amount of electricity consumed by the equipment during the tea processing, the geographical location of the processing plant, etc.

[0026] The carbon emission project in the packaging stage refers to the carbon emissions generated by the use of packaging materials for tea. The corresponding carbon emission source is the packaging material. The relevant information includes: the type and total usage of packaging materials, the geographical location of the packaging factory, etc.

[0027] The carbon emission items in the transportation link are the carbon emissions caused by the energy consumption during the transportation of tea. The corresponding carbon emission sources are gasoline or diesel. The relevant information includes: the distance from the tea garden to the processing plant, the processing plant to the packaging plant, and the packaging plant to the tea sales place.

[0028] The carbon emission items in the consumption link are the carbon emissions caused by the energy consumption in brewing tea. The corresponding carbon emission source is electricity. The relevant information includes: the tea-to-water ratio for brewing tea, the power consumption of different heating appliances for heating the same amount of water, the average power consumption of heating appliances in different usage scenarios, the place where tea is sold, etc.

[0029] The carbon emission project in the disposal stage is the carbon emission generated by the recycling and treatment of tea residues. The corresponding carbon emission source is the different tea residue treatment methods.

[0030] Step S3: Establish a carbon emission factor library for the entire life cycle of tea according to the carbon emission sources corresponding to the carbon emission projects.

[0031] In this embodiment, the emission factors are first divided into three levels according to their sources, namely, high, medium and low.

Then, according to the carbon emission sources corresponding to different carbon emission projects, the high-level emission factors, intermediate emission factors and low-level emission factors involved in different carbon emission projects are obtained according to the above-mentioned division method to construct a carbon emission factor library for the entire life cycle of tea.

[0032] Step S4: Convert the relevant information of the carbon emission project into corresponding activity data, and match the corresponding emission factors in the carbon emission factor library according to the carbon emission sources corresponding to the carbon emission project.

[0033] In this embodiment, activity data refers to data that needs to be further calculated based on relevant information of the carbon emission project. For example, when calculating the activity data corresponding to the carbon emission project (i.e., carbon emissions caused by energy j consumed during tea tree pruning and picking), it is necessary to match the corresponding emission factor (i.e., the carbon emission factor of energy j) in the carbon emission factor library according to its corresponding carbon emission source (i.e., energy j), and then use its relevant information (i.e., the consumption of energy j during tea tree pruning and picking) to further calculate the activity data.

[0034] Step S5: A carbon footprint accounting model is established based on the activity data and emission factors corresponding to the carbon emission projects to calculate the carbon footprint of the entire life cycle of tea. The carbon footprint of the entire life cycle of tea is used to assist tea merchants in adjusting tea production strategies to achieve carbon emission balance.

[0072] This application can calculate the carbon footprint of tea leaves throughout their life cycle more accurately. This advantage mainly comes from the actual measurement of nitrous oxide in the planting process and the consideration of different usage scenarios in the consumption process. The emission factors currently provided by the IPCC are not fully applicable to the actual situation of Chinese tea gardens. Therefore, the actual measurement method is used to calculate the nitrous oxide emissions in tea gardens, which can make the final calculation results more accurate. At the same time, the impact of heating appliances used in different usage scenarios on the carbon footprint of tea leaves throughout their life cycle is considered in the consumption process, so that it can match more usage scenarios more accurately. Therefore, by combining the actual measurement method and the emission factor method and considering the carbon emissions of tea leaves in different consumption scenarios, this application can provide a more accurate calculation method for the carbon footprint of the current tea leaves throughout their life cycle. While improving the calculation method for each tea company or factory, it can more accurately locate the links with higher carbon emissions based on the calculation results to provide more targeted suggestions for carbon reduction, so that tea companies can more flexibly adjust the carbon emission strategies for industrial development.
