We have set out to achieve net-zero greenhouse gas emissions from business processes, products, and services across our organization.

Products & Services: Conserving Energy and Reducing Greenhouse Gas Emissions

LIXIL aims to reduce CO2 emissions to net zero by 2050 and realize its Environmental Vision through the provision of environment-conscious products and services.

Over 90% of CO2 emissions generated during the lifecycle of LIXIL products and services occur during the product use stage. We are taking steps to reduce these emissions and mitigate climate change by improving home insulation to reduce heating and air conditioning demands, reducing the energy required to supply hot water, using renewable energy in product and service development, and utilizing IoT. We are also helping people adapt to climate change by providing solutions for disaster preparedness and indoor heatstroke prevention, for example.

Conserving Energy through High-Grade Thermal Insulation Products

Launching in August 2021, our resin window EW (TOSTEM) boasts a world-class thermal insulation performance and a frame that enhances outdoor scenery and beautifies the interior with its picture frame design. The resin frame’s multilayered, hollow structure and the leading-edge, triple-glass window support the window’s strong thermal insulation performance, restricting heat inflow and outflow and helping to reduce energy used on heating and cooling, thereby reducing CO2 emissions.

Developing Water- and Energy-Saving Products

Heating water constitutes 24% of household CO2 emissions. Reducing the amount of hot water used, therefore, is an effective way to reduce emissions. Our Eco Aqua Shower (INAX) offers double the benefits with a large shower head that emits large droplets of air-filled water for a more comfortable shower experience and better water-saving performance. The shower’s one-push on/off switch makes it easy to save energy and water by up to 48%* compared to the conventional water volumes of 10 liters/min.

Climate Adaptation Solutions

Global warming and the rising frequency of natural disasters linked to climate change are causing dramatic changes to people’s living environments. Our external Style Shade sun blinds (TOSTEM) stop penetration of the sun’s heat on the outside and reduce indoor temperature by as much as 3.5ºC,* cutting energy use for air conditioning and preventing indoor heatstroke.

Promoting Net-Zero Energy Houses (ZEH)

LIXIL TEPCO Smart Partners Inc. (LTSP), a company jointly established by LIXIL and TEPCO Energy Partner, Inc., leases solar-power generation systems to consumers who use LIXIL’s ZEH* building materials and earns income from any surplus energy sold. In return, consumers pay virtually zero yen each month to lease their solar-power generation systems and enjoy favorable electricity rates through the company’s Tatetoku Value service.

* ZEHs realize both a comfortable indoor environment and a substantial reduction in energy consumption with high-insulation and high-efficiency equipment. A ZEH also produces energy with a solar or other power generation system, thereby reducing net annual energy consumption to zero.

In 2021, we launched a Tatetoku Denchi plan that utilizes our energy storage system designed for consumers using designated LIXIL products when building new ZEH-type homes, the service allows consumers to install solar-power generation and energy storage systems at reduced initial costs in exchange for any surplus energy revenue for a period of 10 years.

Reducing CO2 Emissions with IoT-Enabled Products

The growth of online shopping in recent years has increased the number of home deliveries. However, due to the growing number of redeliveries as well, this is cited as reducing labor productivity and increasing CO2 emissions.

LIXIL’s IoT-Enabled Smart Delivery Box facilitates two-way communication between the box and a smartphone, sending notification of deliveries and enabling users to accept multiple separate deliveries. In a demonstration experiment conducted at 100 households in Tokyo, we successfully cut the redelivery rate from 41.7% to 14.9%* and confirmed the efficacy of the product in reducing CO2 emissions.

Business Operations: Promoting Energy Generation and Saving

LIXIL is advancing initiatives across the group to achieve net-zero CO2 emissions from its business processes and realize its Environmental Vision. For example, we are promoting strict energy-saving activities in factories and offices, the development of energy efficiency technologies, and the use of renewable energy.

Improving Energy Efficiency at Production Sites

We are taking steps to improve energy efficiency at each site, such as pinpointing issues with production processes and reviewing equipment.

At our Oyabe Plant in Japan, we visualized the relationship between outdoor temperature and the temperature of the refrigeration machines used in the aluminum surface treatment process. In winter, we were able to reduce CO2 emissions by approximately 494 tons per year by turning off the refrigerator or operating it at a reduced load by using air from outside instead.

At our Ueno Midori Plant, another site in Japan, we identified losses from steam equipment used in production and reduced CO2 emissions by approximately 379 tons a year by improving steam efficiency and replacing existing equipment with eco-friendly alternatives. We have also encouraged factories and distribution centers in Japan to switch to LED lighting, achieving a switchover rate of over 95% to date.

Reducing CO2 Emissions from Distribution

In FYE2021, we launched a round-trip shipping container program as the first shared use of logistics equipment with other companies in the Tokai region of Japan. By allowing other companies to export their goods with containers that LIXIL has finished using to import its exterior materials, we eliminated 130 kilometers of empty container transportation for every round trip. This reduces annual CO2 emissions by roughly 40 tons and transportation costs by approximately 20%.

Our Hokkaido Distribution Center addressed the issues of declining loading efficiency and a driver shortage by combining freight with other companies in the same industry. The initiative successfully reduced the combined driving distance by partner companies by 55,200 kilometers a year and CO2 emissions per tonne-kilometer by 22.7%.

Using Renewable Energy

LIXIL promotes the use of renewable energy as part of its drive to reduce CO2 emissions from its products and services to net zero by 2050. That drive includes our membership in RE100, a global initiative of companies committed to sourcing 100% renewable electricity for their operations.

So far, we have successfully switched to 100% renewable electricity at all LIXIL International water faucet factories and distribution centers (10 locations in total), and at four offices (including our head office), two distribution centers, and 36 sales bases in Japan. Other bases have switched a portion of their electricity use to renewable sources and are working up to 100% renewable electricity in stages. At the end of FYE2021, our renewable energy ratio reached 14.2%, cutting annual CO2 emissions by 62,000 tons.

Eight bases in Japan operate megawatt-scale solar power plants in previously unutilized spaces. Together, these plants generate 34,500MWh of power a year.
