[0002] Global warming has become one of the major challenges to human survival and development. Excessive greenhouse gas emissions from human activities are the main reason for the rise in surface temperature in the past 10 years. Among them, greenhouse gas emissions produced by industrial and agricultural production sectors account for one-quarter and one-fifth of total greenhouse gas emissions respectively. Greenhouse gas emissions from textiles account for 5-10% of global greenhouse gas emissions. Its carbon emissions over its entire life cycle are second only to oil and natural gas, and exceed the total of international aviation and shipping.

[0070] Embodiment 1

[0071] Figure 1 This is a flow chart of a method for generating a carbon label for cotton textiles provided in one embodiment of the present application, with reference to Figure 1 , a method for generating a carbon label for a cotton textile, comprising:

[0072] S11: Determine the carbon emission baseline of cotton textiles in the cotton production stage and cotton processing stage;

[0073] S12: Based on the carbon emission baseline, determine the inputs and carbon emission factors of cotton textiles at each stage of cotton production, as well as the inputs and carbon emission factors of cotton textiles at each stage of cotton processing;

[0074] S13: Determine the carbon emissions of cotton textiles in the cotton production stage based on the inputs and carbon emission factors of cotton textiles in each link of the cotton production stage;

[0075] S14: Determine the carbon emissions of cotton textiles during the cotton processing stage based on the inputs and carbon emission factors of each link in the cotton processing stage;

[0076] S15: Conduct a graded assessment of carbon reduction for cotton textiles based on carbon sequestration and carbon emissions during the cotton production and cotton processing stages;

[0077] S16: Generate a carbon label corresponding to cotton textiles based on the carbon emission reduction grading assessment results of cotton textiles.

[0078] From the entire life cycle of cotton planting, raw cotton processing to cotton textiles, its production and processing process involves two main processes: carbon sequestration and carbon emission. Generally speaking, the life cycle of cotton starts from sowing and enters the light industrial production process after cotton harvest, which is followed by ginning, spinning, weaving, dyeing and garment sewing. There are many types of inputs in the planting stage, which often lead to relatively large environmental impacts. Comparing the carbon footprint of cotton produced in Xinjiang with that of apocynum ramie alternative fibers, it was found that reducing the application of chemical fertilizers can reduce the carbon footprint of cotton. The processing stage is the main source of carbon emissions from cotton textiles, which can be further divided into three sub-stages: raw cotton impurity removal, yarn production and fabric manufacturing. Yarn manufacturing involves spinning, in which cotton fibers are converted into yarn. Then, in the sub-process of processing yarn into fabric, it can be divided into weaving and knitting according to different processing techniques. Shorter fibers usually have a lower carbon footprint than longer fibers. The garment dyeing process is an important part of the textile industry. The process of fabric dyeing is relatively complex and involves the input of many chemicals. The process mainly includes pre-treatment, bleaching, dyeing, soaping, dehydration, drying and printing. Steam consumption in the dyeing and finishing of polyester-cotton knitted fabrics is the largest source of carbon footprint. The specific process of clothing processing includes cutting, sewing, ironing and packaging, and electricity is generally the main input in this life cycle stage. In addition, close or long-distance production can shorten the global supply chain, thereby reducing emissions related to logistics. At the same time, recycling of textiles is an important strategy to reduce the environmental impact of the entire production chain. These measures play a vital role in accelerating the green transformation of the textile industry. At present, the carbon labeling system for cotton textiles is still in the exploratory stage. Since the 1990s, my country has gradually established a certification and labeling system for agricultural products with "three products and one label". The manufacturing energy efficiency labeling system officially implemented in 2005 provides an important reference for the inclusion of low-carbon labels in agricultural products. In recent years, product carbon labeling certification has gradually emerged, but it still only covers a few sporadic products. Cotton textile products have not established a carbon emission labeling system. If carbon labels become a component of cotton textiles, consumers' potential willingness to pay can be increased. At the same time, clarifying the method of producing carbon labels for cotton textiles will provide greater impetus for emission reduction for cotton production and processing entities; based on the above background, a method for generating carbon labels for cotton textiles is proposed.

[0079] It should be noted that the carbon emission baseline of cotton textiles in the cotton production and cotton processing stages includes:

[0080] Obtain technical regulations for cotton production and processing in the region where cotton textiles are located, and collect input data for cotton textiles in the cotton production and processing stages;

[0081] Calculate the average level of inputs for cotton textiles at the cotton production stage and cotton processing stage;

[0082] The average level of inputs for cotton textiles in the cotton production and cotton processing stages is taken as the carbon emission baseline for cotton textiles in the cotton production and cotton processing stages.

[0083] In actual practice, the inputs for cotton textiles in the cotton production and cotton processing stages generally include chemical fertilizers, organic fertilizers, electricity, labor, chemicals, etc.

[0084] It should be noted that to calculate the greenhouse gas emissions of the textile industry, a clear boundary must first be determined. The boundary definition in this technical solution refers to the Greenhouse Gas Protocol - Corporate Accounting and Reporting Standard. The boundary defined in this technical solution is from the cradle of cotton textiles to finished garments, mainly including six stages: cotton planting (cotton production), raw cotton production (ginning), textile yarn (spinning), cloth making (weaving), cloth dyeing (dyeing) and clothing production (ready-made garments).

[0085] Inputs and carbon emission factors of cotton textiles in each link of cotton production stage Figure 2 As shown, it includes: farmland inputs and direct emissions of inputs.

[0086] Among them, farmland inputs include:

[0087] nitrogen fertilizer, phosphate fertilizer, potash fertilizer, compound fertilizer, cotton seeds, pesticides, diesel, agricultural mulch film, labor and electricity;

[0088] Inputs with direct emissions include:

[0089] Diesel combustion and nitrogen fertilizers.

[0090] Inputs and carbon emission factors of cotton textiles in each link of cotton processing stage Figure 3 As shown, including:

[0091] Inputs for ginning, spinning, weaving, dyeing and garment making;

[0092] Among them, the inputs for cotton ginning include:

[0093] electricity, labour and diesel;

[0094] Inputs to the spinning process include:

[0095] electricity and labor;

[0096] Inputs for the weaving process include:

[0097] electricity and labor;

[0098] Inputs for dyeing include:

[0099] electricity, natural gas, sodium hydroxide, hydrogen peroxide, sodium sulfate, phenylhydrazine, silicone oil, and labor;

[0100] Inputs to the garment process include:

[0101] Electricity, gas and labor.

[0102] Among them, the electricity consumption and labor in the three links of ginning, spinning and weaving are the main sources of carbon emissions. There are many chemicals involved in the dyeing stage, and this technical solution does not consider the impact of color on the overall carbon footprint.

[0103] It should be noted that the carbon emissions of cotton textiles in the cotton production stage are determined based on the inputs and carbon emission factors of each link in the cotton production stage, including:

[0104] Based on the input of all farmers in various agricultural inputs and the carbon emission factors of each agricultural input, the total upstream carbon emissions of agricultural inputs in cotton production were obtained;

[0105] According to the input amount of each nitrogen-containing fertilizer during cotton production, the N 2 O emission coefficient and N 2 The relative global warming potential of O on a centennial scale is obtained by the application of nitrogen-containing fertilizers to cotton fields. 2 O Direct carbon emissions;

[0106] According to NH 3 The amount of volatilization loss, the amount of nitrate nitrogen leaching, the amount of nitrogen applied to cotton fields, and the percentage of nitrogen fertilizer lost by nitrate leaching were used to obtain the N loss in cotton fields caused by the input of nitrogen-containing fertilizers. 2 O Indirect carbon emissions;

[0107] The change in soil organic carbon was obtained based on the change in 0-20 cm soil SOC and the conversion factor of the interval year, soil bulk density, topsoil depth and area of ​​cultivated land;

[0108] Based on the total carbon emissions from upstream agricultural inputs in cotton production, the nitrogen-containing fertilizer inputs in cotton fields 2 O direct carbon emissions, N emissions from cotton fields caused by nitrogen fertilizer input 2 O indirect carbon emissions and changes in soil organic carbon are used to determine the carbon emissions of cotton textiles during the cotton production stage.

[0109] In practice, the emission factor is the unit amount of greenhouse gas released, expressed in carbon dioxide equivalent and related activity units. According to the carbon emission inventory list, the product of the input energy use and the emission factor is used as the carbon emission value of the emission project. Calculation method for cotton production stage:

[0110] GHG p =GHGb +GHG d +GHG i -SOC t (1)

[0111] The calculation steps are shown in formula (1), GHG p Represents carbon emissions during the production phase, GHG b Represents upstream emissions from agricultural inputs, GHG d and GHG i Represents direct and indirect emissions from cotton production fields, SOC t Represents the change of soil organic carbon in t years.

[0112]

[0113] GHG b Total carbon emissions from agricultural inputs for cotton production, AM pq is the input of agricultural inputs q by the pth farmer, and EC is the carbon emission factor of each agricultural input.

[0114]

[0115] GHG d N in cotton fields caused by nitrogen fertilizer input 2 O Direct carbon emissions, I i is the input of the i-th nitrogen-containing fertilizer in cotton production, δ i is the N of the i-th nitrogen-containing fertilizer 2 O emission factor, 44 / 28 for N 2 The ratio of O to N atoms is 273 for N 2 O Relative global warming potential on a centennial scale.

[0116]

[0117]

[0118] GHG i N is caused by the input of nitrogen-containing fertilizers. 2 Indirect carbon emissions from O, NH 3dire and NH 3 Volatilization loss and nitrate nitrogen leaching, Q NFI is the amount of nitrogen applied to the cotton field, and 0.3 is the percentage of nitrogen fertilizer lost as nitrate leaching.

[0119] SOC t =dSOC / dt×γ×20 / 10 (6)

[0120] Among them, dSOC and dt are the change of 0-20cm soil SOC and the interval year, γ is the soil bulk density, and 20 and 10 are the conversion factors of cultivated land surface soil depth and area respectively. In most of the research on farming systems in my country, the tillage layer under long-term conventional farming is defined as the 0-20cm soil layer, and the soil organic carbon content is measured by sampling at the 20cm soil layer. Therefore, the 0-20cm soil layer depth is used to calculate the change of soil organic carbon storage.

[0121] It should be noted that the carbon emissions of cotton textiles in the cotton processing stage are determined based on the inputs and carbon emission factors of each link in the cotton processing stage, including:

[0122] Calculate the emission factors, occurrence amounts, and greenhouse gas emissions of cotton textiles at each stage of cotton processing, and obtain the carbon emissions of cotton textiles at each stage of cotton processing;

[0123] The carbon emissions of cotton textiles in each link of the cotton processing stage are summarized to obtain the carbon emissions of cotton textiles in the cotton processing stage.

[0124] In specific practice, the calculation method for carbon emissions in the cotton processing stage is as follows:

[0125]

[0126] The calculation steps are shown in formula (7), EF i represents the emission factor of the ith link, Q i represents the occurrence of the i-th link, EF i *Q i is the greenhouse gas emissions generated by the ith link. The greenhouse gas emissions of all n links are summed up to obtain the greenhouse gas emissions of all links in cotton textile processing, E m .

[0127] It should be noted that a carbon emission reduction grading assessment system is constructed in this technical solution, which generates four types of carbon labels for cotton textiles according to their carbon emissions: "high emissions", "medium emissions", "low emissions" and "negative emissions".

[0128] It should be noted that the method also includes:

[0129] Review the carbon emission baseline of cotton textiles at the cotton production stage and cotton processing stage;

[0130] Regenerate the carbon label for cotton textiles based on the review results;

[0131] Compare the carbon labels of recycled cotton textiles with the historical carbon labels of cotton textiles;

[0132] The authenticity of the carbon label is determined based on the comparison results.

[0133] It should be noted that the review of the carbon emission baseline of cotton textiles in the cotton production and cotton processing stages is carried out within a period of time after the carbon label of cotton textiles is generated, and is generally only carried out once.

[0134] In this technical solution, a mid-term review mechanism for carbon labels of cotton textiles is established to ensure the effectiveness, accuracy and authenticity of carbon label ratings.

[0135] It should be noted that the method also includes:

[0136] Monitor the carbon emission baseline of cotton textiles during the cotton production and cotton processing stages based on a preset cycle;

[0137] Regenerate carbon labels for cotton textiles based on the audit results;

[0138] Compare the carbon labels of recycled cotton textiles with the historical carbon labels of cotton textiles;

[0139] When the difference between the carbon label of the regenerated cotton textile and the historical carbon label of the cotton textile is lower than a preset threshold, the historical carbon label of the cotton textile is replaced with the regenerated carbon label.

[0140] It should be noted that the monitoring of the carbon emission baseline of cotton textiles in the cotton production stage and the cotton processing stage based on a preset cycle is carried out once every certain period of time (for example, one month) after the carbon label of the cotton textiles is generated.

[0141] In this technical solution, a regular monitoring mechanism for carbon labels of cotton textiles is established to ensure the timeliness of carbon label rating.

[0142] This technical solution transforms the carbon reduction dividend brought by the green and low-carbon cotton planting and processing model into a part of the product brand logo. On the one hand, it protects consumers' right to know and helps the society's green consumption transformation. On the other hand, it helps low-carbon attributes become part of the competitiveness of goods and promotes the value-added and price increase of low-carbon cotton textiles. From the perspective of achieving the requirements of the "dual carbon" strategy, market-oriented means are a relatively strong and continuous driving force for achieving this policy goal. The carbon labeling system will help low-carbon products establish market competitive advantages.

[0143] In this technical solution, the inputs and carbon emission factors of cotton textiles in each link of the cotton production stage, as well as the inputs and carbon emission factors of cotton textiles in each link of the cotton processing stage are determined, thereby constructing a carbon emission reduction grading assessment system for cotton textiles, which is used to accurately assess the carbon emissions in the production and processing of cotton textiles.
