Shein's carbon emissions nearly doubled in 2023
Shein, the world's largest fast-fashion retailer, has come under fire for its environmental impact, with carbon emissions nearly doubling in 2023. The company's rapid growth and reliance on air shipping have contributed to a significant increase in its carbon footprint, making it the biggest polluter in the fashion industry.
In 2023, Shein's ultra-cheap clothing crisscrossed the globe, with airplanes ferrying small packages from thousands of suppliers to tens of millions of customers in 150 countries. This rapid expansion resulted in a near doubling of the company's emissions, as reported in its sustainability report. Shein's emissions rose at almost double the rate of its revenue, outpacing other fashion brands in terms of environmental impact.
Shein's business model is based on quick turnaround and mass production, with the company releasing between 700 and 1,000 new items daily, according to CEO Molly Miao. This rapid production and consumption cycle contributes to carbon emissions and waste, as the company primarily relies on air freight for transportation. According to Shein's sustainability report, 38% of its climate footprint comes from transportation, with another 61% originating from other parts of its supply chain.
While Shein has defended its use of AI technology, claiming it helps reduce waste and increase efficiency, critics argue that the company's focus on growth is detrimental to sustainability. Shein's approach to sales, with 70% of its products in stock being less than three months old, encourages consumers to constantly buy new items, fueling demand and contributing to a pattern of overconsumption.
Shein's high emissions and environmental impact have not gone unnoticed, with the company facing criticism and lawsuits. The fast-fashion industry is infamous for its devastating effect on the environment, and Shein's position as the biggest polluter underscores the urgent need for more sustainable practices and accountability in the sector.

The company's unsustainable business model
Shein, the largest fast-fashion retailer in the world, has come under scrutiny for its unsustainable business model and negative environmental impact. The company nearly doubled its emissions in 2023, becoming the biggest polluter in the fashion industry. Its rapid growth and focus on profitability have led to increased carbon emissions, water pollution, and other environmental concerns.
Shein's business model prioritizes speed, efficiency, and mass production to fuel consumer demand. The company leverages AI to predict trends, produce small batches, and quickly scale up popular items. While this approach may reduce waste from unsold items, it contributes to overall pollution and emissions. Shein's reliance on air freight to deliver individual packages to customers in 150 countries accounts for 38% of its climate footprint. The company's use of virgin polyester, a synthetic fabric, further exacerbates the issue, as it contributes to microplastic pollution in waterways.
In addition to transportation and textile waste, Shein's supply chain and sourcing practices have also been criticized. The company sources products and labor similarly to other fast-fashion brands, targeting low-income marginalized communities that are vulnerable to pollution from harmful chemicals and compounds produced by factories. Shein's lack of transparency about its sourcing policies makes it difficult to hold them accountable for the environmental and social impacts of their production processes.
Shein's response to these concerns includes a stated commitment to developing a decarbonization roadmap to address supply chain emissions. They have increased inventory in U.S. warehouses to reduce transportation emissions and are utilizing more cargo ships for deliveries. However, critics argue that until Shein fundamentally reconsiders its business model, its practices will continue to contribute to emissions, waste, and environmental degradation.
Shein's unsustainable business model, characterized by rapid production, global air freight, and the use of harmful materials, has made it the largest polluter in the fast-fashion industry. The company's practices have led to increased carbon emissions, water pollution, and negative impacts on local environments. Shein's response to these concerns includes a focus on reducing transportation emissions, but a more comprehensive approach is needed to address the inherent unsustainability of their business model.

Environmental impact of air shipping
Shipping by air has a significant environmental impact. Air freight is considered high-carbon, and the huge container ships used to ship goods across oceans contribute to air pollution, water pollution, acoustic pollution, and oil pollution.
Marine shipping accounts for 18 to 30% of nitrogen oxides and 9% of sulfur oxides in global air emissions. Nitrogen oxides contribute to the formation of aerosols, ozone, and secondary chemical reactions in the atmosphere, leading to haze and acid deposition. Sulfur oxides create acid rain, damaging crops and buildings, and causing respiratory issues and an increased risk of heart attacks when inhaled.
The shipping industry's substantial tax privileges and the increasing volume of shipping have led to growing emissions. Ships built in the early 2000s were less fuel-efficient than those from the 1990s, contradicting claims of improving environmental performance. However, since 2013, ship design efficiency has improved, and the use of liquid natural gas (LNG) as an alternative fuel can significantly reduce sulfur and nitrogen oxide emissions.
Slow steaming, or reducing the average operational speed of ships, is another effective strategy to reduce carbon dioxide emissions and has been successfully implemented by some shipping companies. While sea freight is generally considered a lower-carbon option than air freight, it still has environmental impacts, including ballast water discharges, which can negatively affect marine life.
Now, addressing your query about Shein's pollution, the company has indeed faced criticism for its environmental impact, particularly as the biggest polluter in the fast-fashion industry. In 2023, Shein's emissions nearly doubled, with 38% of its climate footprint coming from transportation and 61% from other supply chain components. Shein's rapid growth, reliance on air freight, and use of virgin polyester and oil contribute to its high emissions.
Shein has defended its practices, attributing increased emissions to booming business and claiming that technology helps reduce waste and increase efficiency. However, critics argue that Shein prioritizes financial success over sustainability, and its large-scale production model leads to concerns about waste disposal and long-term environmental pollution. Shein has stated that it is developing a decarbonization roadmap to address its supply chain footprint and has increased its use of cargo ships for transportation.

Water pollution caused by textile dyeing
SHEIN, the largest fast-fashion retailer in the world, has been dubbed the biggest polluter in the fast-fashion industry. The company nearly doubled its emissions in 2023, with a 57% increase in production volume and a 52% increase in emissions. SHEIN's sustainability report revealed that 38% of its climate footprint stems from transportation, while 61% comes from other supply chain components. The company's rapid use of virgin polyester and oil production, as well as its contribution to carbon emissions, have raised concerns about its environmental impact.
One of the major environmental concerns associated with fast-fashion brands like SHEIN is water pollution caused by textile dyeing. The fashion industry is a significant contributor to water pollution globally, with an estimated 17%-20% of industrial water pollution attributed to textile dyeing and treatment processes. The chemicals used in dyeing textiles not only contaminate water sources but also harm aquatic life and ecosystems.
Textile mills consume vast amounts of water, with up to 200 tons of water used per ton of dyed fabric. This water is then discharged as hazardous toxic waste, containing residual dyes and harmful chemicals. The wastewater from these mills is considered the most polluting among industrial sectors, and the lack of regulation in wastewater disposal exacerbates the problem. The dyeing process itself results in a significant loss of colorants, ranging from 10%-50%, which further contributes to environmental pollution.
Synthetic dyes, which offer a wider range of colors and are more affordable and easy to produce, have largely replaced natural dyes. However, these synthetic dyes have detrimental effects on the planet, causing air, water, and soil pollution. Natural dyes, on the other hand, are not inherently pollution-free, as they also require large amounts of water and can pollute groundwater and rivers if metallic compounds are used as mordants and not properly disposed of.
To address water pollution caused by textile dyeing, several initiatives and alternatives have been proposed. These include the use of AirDye processes, which significantly reduce water consumption during dyeing, and the development of bioremediation approaches to treat textile dye effluents. While some natural dyes, known as Substantive Dyes, can adhere to fibers without the use of mordants, the shift toward synthetic dyes in the industry has negatively impacted the environment.
