The company's product range includes toilets, bidets, faucets, showers, and bathroom accessories. Environmental sustainability is at the core of TOTO’s philosophy, as they strive to develop eco-friendly products and practices, such as water-saving technologies, energy-efficient systems, and sustainable manufacturing processes. By combining innovation with environmental stewardship, TOTO aims to contribute to a healthier planet while enhancing the everyday lives of its customers. The company commissioned this study to evaluate the potential environmental impacts of its flagship product, the WASHLET® S7, using a cradle-to-grave approach.  \nThis study covers the entire WASHLET® S7 series, a collection of 10 models: SW4726, SW4726(AT40), SW4724, SW4724(AT40), SW4736, SW4736(AT40), SW4734, SW4724(AT40), SW4735, and SW4725 . These models all have the same material composition and differ only in the features offered and aesthetics (color) . All are assembled in a single TOTO facility in Malaysia, with product parts coming from various suppliers.  \nA functional unit of one unit of product over the estimated service of the building was used for the assessment. The estimated service life of the building (ESL) is 75 years, and the reference service life (RSL) is 15 years. This life cycle assessment (LCA) was conducted conforming to the relevant PCRs and applicable ISO standards using a cradle-to-grave approach, including all life cycle stages from raw material extraction through final assembly, transportation of materials between supplier facilities and manufacturing facilities, manufacturing operations, distribution to end users, resource consumption during product use, and end-of-life disposal.  \nA high-level summary of the findings of this study is illustrated in the table below which shows impacts per functional unit. The table presents potential CO2-equivalent emissions and SM single score results for the WASHLET® S7 . For other impact categories and a breakdown by each life cycle stage, refer to section 5.2 in the full report. Overall, the study found that environmental performance is driven primarily by the use phase of the product. The impacts within the use phase are dominated by the product replacements and electricity consumption for bidet operations. The product must be replaced four times to meet the prescribed ESL of 75 years. The cumulative impact of manufacturing, distributing, and disposing of multiple units over the desired service period makes product replacement resource and energy intensive. Washlets consume a considerable amount of electricity peruse, which adds up significantly for the ESL period and leads to significant potential environmental impacts. Raw materials extraction, upstream transportation, and the manufacturing of the product also represent a considerable share, but it is minimal when compared to the impacts generated in the use phase.  \n\n| Impact categories | Unit | Production | Construction/ Installation | Use | End of life | Total |\n| --- | --- | --- | --- | --- | --- | --- |\n|  |  | A1-A3 | A4-A5 | B1-B7 | C1-C4 |  |\n| Global warming | kg CO2 eq | 1.59E+02 | 5.78E+01 | 2.49E+03 | 2.32E+00 | 2.71E+03 |\n|  | % | 5.85% | 2.13% | 91.94% | 0.09% | 100% |\n| SM single figure score | mPts | 1.82E+01 | 3.42E+00 | 1.59E+02 | 7.82E-02 | 1.81E+02 |\n|  | % | 10.09% | 1.89% | 87.97% | 0.04% | 100% |\n\nCONTENTS  \n1.
