“…Especially the large amount use of raw coal, heating power and electric power of textile industry in Jiaxing which lead to the tremendous emissions of carbon dioxide has a significant impact on the result of EP&L c . According to the research of Chen et al, the carbon emissions of cashmere fabrics in manufacturing process is two orders of magnitude larger than water consumption per functional unit [35] Besides, social marginal cost of unit water consumption lower than the social cost of carbon is also a big factor to the EP&L value. The high social marginal cost of carbon reflects that people attach more importance to carbon dioxide emission, which leads to a high estimate value of SCC.…”

The textile industry is a typical energy-intensive and water-intensive industry, causing a large amount of greenhouse gas emission and wastewater discharge. How to evaluate the environmental degradation caused by textile industry more intuitively and objectively has aroused great concern in recent years. The Environmental Profit and Loss (EP&L) is a method to evaluate the environmental impact intuitively as it converts different environmental impacts into a unified social marginal cost. In this paper, EP&L methodology and an innovative indicator, which is Environmental Profit and Loss intensity (EP&L in ), were applied to evaluate the environmental impacts caused by carbon dioxide emission and water consumption of textile industry in Jiaxing from 2011 to 2018. The results showed that the total EP&L value converted from carbon dioxide emission of textile industry in Jiaxing presented an upward trend from 2011 to 2018. The maximum EP&L value due to carbon dioxide emission reached to US$ 729 million in 2018. The total EP&L value of water consumption was increased from US$ 0.4 million in 2011 to US$ 0.5 million in 2018. During this period the EP&L in of textile industry in Jiaxing went up from 0.1090 to 0.1283, and the EP&L in of carbon dioxide emission was much larger than that of water consumption. Additionally, among the three sub-sectors (manufacture of textile, manufacture of chemical fibers and manufacture of textile, wearing apparel and accessories), the manufacture of textile sector's EP&L value converted from carbon dioxide emission and water consumption accounted for approximately 60% of the total EP&L value of textile industry in Jiaxing, much larger than that of the other two sub-sectors. The manufacture of chemical fibers sector had the largest EP&L in from 2012 to 2018. This result indicated that manufacture of chemical fibers

Dyes play an important role in textile production, but their contribution to air pollution and harming human health have raised concerns and remain an international problem. The key to overcoming this challenge is to assess how much greenhouse gases are being generated and the hotspots which guide decision-making process toward more sustainable options. This article established a carbon footprint calculation method for disperse dyes. First, the system boundary description and the functional unit were discussed. Second, the carbon footprint inventory analysis was determined. What’s more, the calculation method, allocation method and emission factors were proposed. It was intended to be practical and effective based on three typical disperse dyes in China. The results showed that the carbon footprints of Disperse Blue 79, Disperse Red 167, and Disperse Orange 61 corresponded to 8.28 t CO2 eq/t, 8.07 t CO2 eq/t, and 7.48 t CO2 eq/t, respectively. For the three disperse dyes, the carbon emissions of dispersing agent melamine-formaldehyde resin and liquid ammonia consumption were the dominant emission sources. The steam and electricity were the two major sources of carbon emissions caused by energy usage. The homogenization and the wastewater treatment process were the two largest emission emitters. The sensitivity analysis showed that the total product carbon footprint was mostly sensitive to dispersing agent melamine-formaldehyde resin changes, followed by steam, liquid ammonia, and electricity. The results show that disperse dye production have great potential for improvement. The reduction options for the emissions of the disperse dyes production can be concluded by the optimization of the production process and technology for dispersing agent melamine-formaldehyde resin, liquid ammonia, electricity, and steam. Through the calculation, the influencing factors for the carbon footprint can be analyzed and highlighted. The method provides a comprehensive understanding of environmental impacts with dyes, driving the adoption of sustainable dyeing practices.

“…Carbon footprint analyses were performed on ten different cashmere fabrics according to the PAS 2050 specification, water footprint network approach, and ISO 14046 standard. According to the results of the analysis, it was stated that knitted cashmere fabrics have a higher carbon footprint than woven cashmere fabrics [5].…”

The effect of industrialization and technological developments and the rate of population growth have begun to disrupt the ecological balance in the world. A large share of the deterioration of this balance is due to the rapidly increasing energy demands of people. Fossil fuels and renewable energy sources are used to obtain the energy that is needed by human beings. Most of the world’s energy needs are met by fossil fuels such as coal, oil, and natural gas. These resources, which we call fossil fuels, cause many parallel environmental problems, such as global warming, climate change, and carbon emissions, for the world and nature. The most affected by all these experiences, of course, is the entire production sector, which is dependent on energy. However, textile and apparel, which is a pioneer in taking steps towards harmonization with the Green Agreement, is one of the sectors that started the transition to green energy within the scope of the European Union and brands’ net-zero targets. Within the scope of the Green Agreement, Turkey has participated and started to work for a 70% carbon reduction, which is the target for 2030, and carbon neutrality, which is the target for 2050. Therefore, within the scope of these targets, the textile sector of Çukurova Region, which has the highest export rate in Turkey, was chosen. Within the scope of this study, carbon emission, which is one of the global problems, was examined within the framework of the ISO 14067-ISO Product Based Carbon Footprint (CF) standard by examining the production of a textile company, and the results were analyzed in detail. The main innovation of this article is to follow all stages of the fabric called Tricia, which is the most produced product in the textile industry, from its entry as fiber to its exit as fabric in the factory, and to calculate and analyze the amount of carbon that is released into nature. The dynamic and experimental results showed that it was determined that 6.00 tons of carbon dioxide carbon were released in the time it took for the fabric to go to the sewing room as a fabric.
