Product Life Cycle Assessment

Product Environmental Assessment is a method of evaluating the environmental performance of new products by identifying CO₂ emissions using Life Cycle Assessment(LCA)*1 and evaluating water and energy saving capabilities and consideration of the 3Rs of the environment during the product planning and design processes in order for us to continue developing environmentally friendly products and improve their environmental performance.

The TOTO Group evaluate the environmental impact during the product planning and design process by referencing guidelines related to Life-Cycle Assessment (LCA), and strive to improve the energy-saving and water-saving performance of our products.

*1 Life Cycle Assessment（LCA）: LCA is a procedure to quantitatively and objectively evaluate the environmental impact throughout all stages of the product life cycle from procurement of product-related materials to manufacturing, transport, use, and disposal.

Products Environmental Assessment

Items of environmental performance assessment	Descriptions
LCCO2 (Life cycle CO2)	CO2 emissions at each stage of the product life cycle
Water-saving	Water consumption during product use
Energy-saving	Energy consumption during product use
Consideration of 3Rs	3Rs promotion during manufacturing and designing [Reduction of product mass, use of recycled materials, Use of renewable resources, easy degradability, material indication]
Air purification	Purification of contaminated substances (air/water) during product use
Reduction of harmful chemical substances	Reduction of contamination (air/water) throughout the entire life cycle
Biodiversity (timber)	Use of legal timber for wood materials and recyclable materials in the procurement stage

In light of increasing expectations for the highly transparent disclosure of environmental data aimed at achieving carbon neutrality in recent years, we have been objectively assessing the entire value chain for major products. As part of these initiatives, we have acquired Environmental Product Declarations (EPDs)^*2 for representative products such as seated toilets, wall-hung toilets, lever-style faucets, WASHLET, and smart toilets. EPD is a report verified by a third party that quantifies the environmental impact of a product throughout its entire life cycle, from raw material acquisition to manufacturing, logistics, use, and disposal or recycling. Going forward, we will work to promote the understanding of environmental impact at each stage of the value chain through LCAs and reduce the impact.

*2 The region of sale and the EPD program to be obtained vary depending on the product.
