We aim to eliminate deforestation caused by resource extraction from designated protected areas under the law, and our goal is to use sustainably sourced materials for all products that use palm oil, timber, and cotton sold domestically by 2050. Our wool and down raw materials are sourced with consideration for animal welfare.

We conduct regular surveys to ensure traceability of the origin and promote initiatives for the sustainable use of palm oil by verifying origin certificates and other means.
In December 2023, we became a member of JaSPON (Japan Sustainable Palm Oil Network) to gather information and move toward the future procurement of certified palm oil.

We consider biodiversity conservation, conscientiously ensure traceability to the point of origin, and promote the procurement of sustainable cotton. We are committed to environmentally responsible manufacturing and considerate of the producers.

For MUJI products　and MUJI HOUSE residences, we aim for sustainable procurement of wood and paper materials^*1 and have set a goal of achieving 100% utilization of certified materials related to forestry (FSC, PEFC, SGEC) or materials that comply with environmental laws on logging in each country and region by 2030. To achieve this goal, we conduct investigations into legal logging practices and self-assessments (wood due diligence) to ensure that we do not use wood associated with deforestation caused by illegal logging and similar activities.
For fixtures, interiors, and exteriors at our stores in Japan, we actively utilize domestic and regional timber to support the stability of the timber and forestry industries. In May 2023, Ryohin Keikaku Co., Ltd. and MUJI HOUSE Co., Ltd. signed the "Agreement on Promoting the Expanded Use of Timber in Buildings" with Japan's Ministry of Agriculture, Forestry, and Fisheries. Under this agreement, we aim to use approximately 10,000 m³ of domestic timber over five years and ensure the use of legally verified wood in compliance with Japan's Clean Wood Act. By promoting the use of domestic timber, we contribute to the realization of a decarbonized society. Additionally, by sourcing raw timber and processing products locally for stores in each region, we aim to support regional wood industries.

*1. Excludes wood at the end of its lifecycle, paper made from non-wood pulp, and cardboard.

Moving forward, we will continue to utilize the spatial design expertise of the Ryohin Keikaku Group and actively promote the use of timber in MUJI stores and other buildings.

*2. ZEB stands for "Net Zero Energy Building," referring to structures designed to achieve zero or negative annual primary energy consumption. "MUJI Karatsu" and "MUJI Hita" has obtained "ZEB" certification at the level of representing the lowest energy consumption in the four-tier ZEB evaluation system. This certification is based on the performance evaluation under BELS (Building-Housing Energy-efficiency Labeling System), and the two buildings were certified on January 10, 2024.

*3. The CO₂ reduction rates were calculated using the "One Click LCA" carbon assessment software, with a simplified evaluation conducted by New Constructor's Network Co., Ltd. These figures are provisional and may be revised in the future. The reduction rates are based on CO₂ emissions per square meter of building area.
