Fast Retailing aims at carbon neutrality by 2050. Efforts to do so include reducing its carbon emissions by 20 per cent in 2030. Since 2017, Fast Retailing has published a list of core sewing partner factories and since 2018 has expanded the list to include core fabric mills. By March 2022, the company plans to publish a list of all sewing partner factories it has ongoing dealings with. In addition to audits at garment factories and core fabric mills, the company aims to establish traceability across the whole supply chain, from upstream spinning mills to raw material level. The company will identify and correct any human rights or labor environment issues at an early stage. This also includes a gender equity-based policy, including an increase in the representation of female management in the company to 50 per cent by 2030, hiring people with disabilities, and enhancing LGBTQ friendliness of environments for both employees and customers.

Fast Retailing is the company behind the brand Uniqlo. All 64 Uniqlo stores from nine markets in Europe have switched over to renewable energy. By the end of 2021, all stores in North America and in some countries in southeast Asia will complete this switch.
