Development of environmentally friendly products (Products Environmental Assessment)

Product Environmental Assessment is a method of evaluating the environmental performance of new products by identifying CO2 emissions using LCA* 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 evaluates environmental performance by setting evaluation items with reference to LCA guidelines and case studies. As a result of the assessment, the TOTO Group found that our CO2 emissions and water consumptions were significantly high in the use stage. We consider the reduction of CO2 emissions, energy saving, and water saving as key environmental performance factors, and we are working to reduce the product environmental burden.

*LCA (Life Cycle Assessment): 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

Lifecycle Assessment

*A lifecycle assessment quantifies and objectively evaluates the impact of a product on the environment in every stage of its life from the gathering of materials to production, transportation, usage and disposal.

TOTO green products sales ratio

TOTO has facilitated the development and expanded use of "TOTO green products," defined as environmentally friendly, high-performance products. In fiscal 2023, green products accounted for 83% of net sales for the TOTO Group as a whole.
