LCA results & interpretationStandard EcoPower® Faucet with Mixing Valve
Scope and summary
- Cradle to gate
- Cradle to gate with options
- Cradle to grave
One faucet in an average U.S. commercial environment for 3 years. The period of 3 years is modeled as the period of application based on the average technical lifespan for commercial applications. The economical lifespan of commercial applications can be longer or shorter due to aesthetic replacements or more intense use. The implication is that the LCA model assumes that the application ends at year 3 and that the materials will be treated in an end-of-life scenario.
Reference service life: 3 years
Data reporting period: 2015
Default use phase scenario
TEL105-D10ET and TEL105-D10EM: 3 years of service in an average U.S. commercial environment with 0.09 gallon/use and 133 uses/day resulting in 13,107.15 gallons of water.
TEL105-C20ET and TEL105-C20EM: 3 years of service in an average U.S. commercial environment with 0.19 gallon/use and 133 uses/day resulting in 27,670.65 gallons of water.

What’s causing the greatest impacts
All life cycle stages
The production stage is dominating the results for most impact categories. The production stage has the most significant contributions to eutrophication (mostly from emissions from copper mining and the printed wiring board), non-carcinogens (emissions from the production of copper and zinc) and ecotoxicity (mostly from disposal of steel slags and bottom ashes from coal fired power plants, and barium emissions to water from the extraction process of natural gas). The use phase is relevant to most impact categories, especially fossil fuel depletion, ozone depletion, carcinogenics, and global warming. The use stage impact is mostly due to the embedded energy arising from acquisition, treatment and distribution of the water used during the use of the product.
The recovery stage includes recycling processes and benefits by preventing the need to produce primary materials. Recycling is a relevant factor for some of the impact categories, offsetting a portion of the impacts caused by production. Additionally, the delivery of the product to the construction/installation site, the construction/installation processes, the processes for dismantling the product and final waste treatment during the end of life stage do not have a significant impact.
Brass parts and the printed wiring board, along with the brass turning process have significant contributions to the impact categories. Stainless steel materials and the turning steel process are relevant to the carcinogenics category. The electroplating process along with injection molding are major contributors to the ozone depletion catgory. Additionally, polishing has a somewhat significant processing contribution to the results. Transport via oceanic freighter appears as a relevant contributor to the fossil fuel depletion and smog categories.
Deviations in the LCA results are a result of the difference in the assembly parts of the two faucets as well as the use phase. TEL105-D10ET and TEL105-C20ET contain more mass than TEL105-D10EM and TEL105-C20EM. The continuous cycle uses more water per cycle than the on-demand version of the two faucets.
Multi-product weighted average
Results represent the weighted average using production volumes for the products covered. Variations of specific products for differences of 10-20% against the average are indicated in purple; differences greater than 20% are indicated in red. A difference greater than 10% is considered significant.
TOTO programs improving environmental performance
- TOTO’s EcoPower® products are powered by the force of running water.
- The electronic and mechanical components are programmed and designed to allow water flow and accurate flush volume only when needed.
- Water consumption is reduced in the use phase due to superior flushing performance.

LCA Background Report
Part A: LCA Calculation Rules and Background Report Requirements v2016 (compliant with ISO14040-44 and ISO14025)
Transparency Reports™ / environmental product declarations enable purchasers and users to compare the potential environmental performance of products on a life cycle basis. They are designed to present information transparently to make the limitations of comparability more understandable. TRs/EPDs of products that conform to the same PCR and include the same life cycle stages, but are made by different manufacturers, may not sufficiently align to support direct comparisons. They therefore, cannot be used as comparative assertions unless the conditions defined in ISO 14025 Section 6.7.2. ‘Requirements for Comparability’ are satisfied.
The intent is to reward project teams for selecting products from manufacturers who have verified improved life-cycle environmental performance.
