Environmental Sustainability in the Fashion Industry: A Comprehensive Overview

The Urgent Need for Sustainable Fashion

The fashion industry, valued at USD 1.3 trillion and employing over 300 million people worldwide, faces increasing scrutiny for its substantial environmental and social impacts. Fast fashion, characterized by rapid production and consumption of low-cost garments, exacerbates issues such as pollution, water usage, carbon emissions, human rights abuses, and gender inequality. These challenges necessitate a decisive shift towards sustainability within the global fashion economy, with collaborative efforts spearheaded by organizations in Geneva and beyond.

Environmental Impact of the Fashion Sector

Scale and Growth

• Global fiber production nearly doubled between 2000 (58 million tonnes) and 2022 (116 million tonnes) and is projected to reach 147 million tonnes by 2030 if current trends persist (Textile Exchange, 2023).
• Consumers bought 60% more garments in 2014 compared to 2000 but kept them for half as long (McKinsey & Company, 2016).

Resource Consumption and Pollution

• The fashion industry is the second-largest consumer of water globally, utilizing approximately 215 trillion liters annually—equivalent to 86 million Olympic-sized swimming pools (Quantis, 2018).
• It accounts for 2-8% of global carbon emissions, with projections suggesting this could rise to 26% by 2050 without intervention (Ellen MacArthur Foundation, 2017).
• Approximately 20% of industrial wastewater pollution worldwide originates from textile manufacturing (World Bank, 2020).
• Synthetic fibers constitute about 60% of materials used, contributing significantly to plastic pollution and microplastic release—500,000 tons enter the oceans annually, comparable to 50 billion plastic bottles (Ellen MacArthur Foundation, 2017; UNEP, 2019).
• Each second, the equivalent of one garbage truck full of clothes is disposed of in landfills or incinerated (Ellen MacArthur Foundation, 2017).
• Less than 1% of clothing materials are recycled back into new textiles, resulting in more than $100 billion in material value loss annually (Ellen MacArthur Foundation, 2017). The Circularity Gap Report Textiles (2024) further reveals only 0.3% of resources used in global textile production derive from recycled materials.

Social and Human Rights Concerns

The fast fashion model frequently depends on textile workers, predominantly women in developing countries, who often face poor wages, excessive working hours, and unsafe conditions. These labor practices violate fundamental human rights and contribute to broader social inequalities (UNEP, 2018; WRI, 2019; Human Rights Watch). Additionally, the use of hazardous chemicals in textile production raises critical health concerns for both workers and consumers.

The Plastic Fate of Fashion

Following World War II, synthetic textiles such as polyester and nylon transformed fashion. Today, synthetic fibers dominate textile production, making up about 64% globally (European Environment Agency). These plastic-based materials have a lifetime footprint that contributes to greenhouse gas emissions, plastic pollution, and microfibre contamination of oceans, which accounts for roughly 9% of annual microplastic pollution (UNEP, 2021).

Calls for Action and International Cooperation

Addressing the fashion industry’s environmental and social footprint requires:

• Investments estimated at an additional $20-30 billion per year focused mainly on energy efficiency, water conservation, and waste reduction (Ellen MacArthur Foundation, 2017).
• Greater circularity and recycling initiatives to reduce resource extraction and waste generation.
• Robust international agreements and governance frameworks tackling plastic pollution, as underscored by ongoing UN Environment Assembly negotiations following the 2022 resolution.
• Improvement in labor standards and health safeguards for workers across fashion supply chains.

• UNEP’s Plastic Pollution Crisis and related governance efforts

In Summary: The fashion industry’s environmental and social costs are mounting, driven largely by the fast fashion business model and the dominance of synthetic textiles. Transformative changes focusing on sustainability, circularity, and human rights are indispensable for mitigating the substantial negative impacts while aligning the sector with global Sustainable Development Goals (SDGs 3, 5, 6, 10, 12, and 13). Collective action, transparent governance, and committed investment will chart the course toward a more responsible and equitable fashion future.
