Greenhouse Gas Reduction



The LIXIL Group is focused on developing products and services that can help realize a low-carbon or decarbonized society, as well as actively reducing greenhouse gas emissions in its operational processes.

Action plan ・Pursue more environment-conscious product design and sales expansion strategies, taking into account the entire lifecycle of both products and services
・Improve CO2 emissions/units
KPI Group-wide:
1. Benefits from CO2 emissions reduction achieved from the products and services
2. Levels of CO2 emissions across all operational processes

Target / ProgressOPEN or CLOSE

  • Target for FY2016

  • 1. Create a guideline for calculating the decrease in CO2 emissions to help achieve our mid-term target for FY2016-20 (1.4 times more efficient than in FY2015), and monitor the FY2015 result

    2. Target -1.6% in FY2016 compared to FY2015 to achieve our new mid-term CO2 emissions target for FY2016-20 (-8% v. FY2015)
    *Above includes water resource conservation data (indirect avoided emissions and actual emissions related to water use)

  • Progress as of 2016

  • 1. Contributions from CO2 emissions reduction achieved from products and services increased by 1.08 times (compared to FY2015). Created Guideline for Calculation of Environmental Contribution to clarify calculation method for individual products and services, and calculated results based on FY2015 performance

    2. CO2 emissions from operational processes increased by 5% (compared to FY2015). Set targets and initiatives for each business organization in compliance with med-term targets

    ・Created Guideline for Calculation of CO2 Emissions from Value Chain to clarify calculation method for all processes from procurement of raw materials through to product disposal

  • Target for FY2017

  • 1. Group-wide benefits from CO2 emissions reduction achieved from products and services increased by 1.16 times (compared to FY2015) to achieve our mid-term CO2 emissions target for FY2016-20

    2. Group-wide levels of CO2 emissions across all operational processes reduced by 3.2% (compared to FY2015) to achieve our mid-term CO2 emissions target for FY2016-20
    *Above includes water resource conservation data (indirect avoided emissions and actual emissions related to water use)

Improving Energy Efficiency of Products and Services

The LIXIL Group pursues the development of low-carbon and energy-saving products and services to achieve a net zero balance between our environmental footprint and our positive environmental contribution. In FY2016, we completed the Guidelines for Calculation of Environmental Contribution, which is our global guideline to measure the positive environmental contribution of our products and services. Going forward, we intend to strengthen our focus on product lifecycle and expand our range of environment-conscious products.

LIXIL Navish hands-free faucets

LIXIL's Navish hands-free faucets use automatic Eco Sensors to detect the presence of hands and other objects, enabling water to be dispensed and stopped without touching the faucet. Faucets equipped with the Eco Sensor function also separate hot and cold water, preventing unintended use of hot water and energy. Compared to conventional faucets, users can expect to see energy savings of about 52%, and water savings of about 31%.

To reduce energy consumption from air conditioning, it is important to improve the thermal insulation of openings in the home. These represent the greatest inflow and outflow of heat. Following the introduction of LIXIL's high-performance SAMOS X hybrid aluminum and resin windows, in FY2016 LIXIL introduced SAMOS L, a strategic product designed to be more affordable while maintaining high thermal insulation. In addition, ERSTER X, a resin window aimed at providing the top-class level in thermal insulation performance, has been joined by ERSTER S, a resin window at a more affordable price point.



Permasteelisa mfree-SCCF

Introduced by Permasteelisa in 2008, mfree-SCCF (moisture free Sustainable Close Cavity Façade) curtain walls feature double-skin glass walls with compressed-air internal cavity. The Permasteelisa Group's proprietary technology offers outstanding performance from the perspectives of ecological sensitiveness, comfort, and aesthetic appeal. Many buildings with these curtain wall exteriors have received acclaim and certification by green building rating systems such as Leadership in Energy and Environmental Design (LEED) and the Building Research Establishment Environmental Assessment Method (BREEAM).

Expanding Net Zero Energy Housing

In FY2016, LIXIL also worked to promote Net Zero Energy Housing (ZEH).* In October 2016, we renamed the Exterior Business Department the ZEH Solutions Division to further our focus on promoting ZEH in Japan. In April 2017, we also began offering ZEH Design Support Services to assist builders in designing houses that meet ZEH criteria. By providing both building materials with high-performance thermal insulation and design services for builders, LIXIL is helping to promote the growth of ZEH in Japan.

*A house that achieves net zero energy consumption through the use of improved thermal insulation, energy-saving technology, and renewable energy-generating equipment such as solar panels. The definition or criteria of a net zero energy house can vary by country.

Promoting Energy Creation and Saving

Each business within the LIXIL Group sets targets and implements initiatives in line with our medium-term goals, which includes creating and saving energy in operational activities. In FY2016, we established the Guideline for Calculation of Value Chain CO2 Emissions and are currently implementing these guidelines Group-wide.

We are implementing a number of initiatives to reduce energy consumption in all of our business processes, including switching to LED lighting in our offices and installing systems that encourage environmentally efficient use of commercial vehicles in Japan.

Scope: FY2014 covers operation in Japan and Asia, while FY2015 and FY2016 cover a majority of the entire Group
*Cargo shipped by LIXIL Corporation is covered

Establishing a solar power system

LIXIL Corporation is promoting the generation and use of renewable energy by turning idle land and factory roofs into mega-solar power plants at five of its sites in Japan. The five sites combined generate approximately 28,900MWh each year, equivalent to the annual power consumption of roughly 5,800 households in Japan. At the end of April 2017, we also introduced a similar system at Minakuchi distribution center and Kumayama factory.

LIXIL Chita SOLAR POWER generated approx. 6,700MWh in FY2016

Energy savings at manufacturing sites

In July 2016, the GROHE Lahr Plant in Germany introduced a new CHP unit, replacing two inefficient boilers. The new CHP unit is providing heat for two electroplating lines and can supply up to 30% of the plant's demand for electricity. In addition to better overall energy efficiency, it also enables the plant to reduce CO2 emissions by 2,500 tons per year.
At the GROHE Hemer Plant, a CHP unit introduced in 2015 is reducing 15% of the plant's electricity consumption from the use of "recovered heat," generating a savings of 2,200 tons of CO2 per year.
All GROHE plants and distribution centers around the world were successfully certified according to ISO 50001 Energy Management Systems by the end of 2016.
