Fashion’s Carbon Impact
The fashion industry accounts for an estimated 4-8% of global greenhouse gas emissions — more than international flights and shipping combined. The majority of fashion’s carbon footprint comes from raw material production (fiber farming and extraction), fabric manufacturing (dyeing and finishing are particularly energy-intensive), and consumer care (washing and drying over a garment’s lifetime). Transportation, often assumed to be the largest contributor, typically accounts for only 5-10% of total lifecycle emissions.
Measuring and Reducing Fashion Carbon
Brands measure carbon footprint at the product level (lifecycle assessment per garment), corporate level (Scope 1, 2, and 3 emissions), and supply chain level (supplier-specific carbon intensity). Reduction strategies include transitioning to renewable energy in manufacturing, optimizing logistics routes and modes, selecting lower-carbon materials (organic cotton, recycled polyester), reducing overproduction, and designing for longevity to extend garment lifespans.
Carbon Commitments and Accountability
Major fashion companies have made public carbon reduction commitments: the Fashion Industry Charter for Climate Action targets 30% reduction by 2030, many brands have set Science-Based Targets (SBTi), and some have committed to net-zero emissions by 2050. However, accountability remains challenging — Scope 3 supply chain emissions, which represent 80-90% of fashion’s total footprint, are difficult to measure and even harder to control.
OSF Perspective
OSF views carbon footprint measurement as essential infrastructure for fashion's sustainability transformation. Without accurate, comprehensive carbon accounting, commitments to climate action remain aspirational. The brands that invest in rigorous measurement today are building the foundation for credible, verifiable environmental leadership.
