Water Conservation & Environmental Sustainability



Conserve water, energy, and other natural resources utilized in and by LIXIL products and services across the value chain from procurement through production, distribution, end use, and product disposal.

Situation on the Ground

The 2015 Paris Agreement seeks to keep the rise in global average temperature well below 2°C above pre-industrial levels, and aims to limit that rise to 1.5°C. To achieve this, the world must reduce CO2 and other greenhouse gas emissions to net-zero by 2050.

In addition, an estimated 800 million people around the world today do not have access to safe drinking water. By 2050, over 40% of the world’s population won’t have access to necessary water supply due to the depletion of water resources.

Furthermore, global resource consumption is expected to more than double by 2050. To help change this situation, the world is gradually shifting from a one-way economy, which mines resources, makes products in large quantities, and eventually discards them, to a circular economy that closes resource loops.

Our Strategy

In order to realize LIXIL’s Purpose of “making better homes a reality for everyone, everywhere,” we have determined Water Conservation & Environmental Sustainability as one of the strategic pillars of our CR Strategy and positioned the following five areas as priority material issues.

  • (1) Climate Change Mitigation and Adaptation
  • (2) Water Sustainability
  • (3) Circular Economy
  • (4) Environmental Impact of Product Lifecycle
  • (5) Environmental Management

LIXIL Environmental Vision 2050

The LIXIL Environmental Vision 2050, which was compiled in FYE2020, declared a commitment to Zero Carbon and Circular Living and made the material issues (1)-(3) above as focus areas for realizing the vision. As a springboard for promoting these focus areas, we have been striving to reduce environmental impact throughout the product lifecycle (4) and to strengthen our companywide environmental management (5). By 2050, we aim to achieve net-zero carbon emissions and preserve water and natural resources in operations, housing and lifestyle solutions for future generations to become a leading company in environmental sustainability.

Climate Change Mitigation and Adaptation

The energy consumed by LIXIL products during their endues phase is the major source of CO2 emissions in the lifecycle of LIXIL products and services, from raw material procurement through to product disposal. At LIXIL, we strive to reduce our environmental impact and aim to achieve net-zero CO2 emissions by 2050 by offering eco-conscious products and services.

We also seek to provide products and services that can help alleviate the damage caused by rising temperatures, increased rainfall, major typhoons, and other natural disasters brought about by climate change in order to advance climate adaptation.

Water Sustainability

As a leading company in the water-related product industry, providing products such as toilets, kitchen systems, prefabricated bathrooms, and faucets, LIXIL strives to help achieve global water sustainability so that people can get the most out of the water they use.

To that aim, we seek to create additional environmental value for water by encouraging the use of water purification technologies and products and services that reduce water consumption, such as water-saving toilets and faucets, and smart water controllers. At sites that use water for manufacturing, we take appropriate steps to improve water efficiency, recycle water, and manage wastewater.

Circular Economy

LIXIL uses a variety of resources, including metals, timber, resin, and ceramics. In order to use limited resources more sustainably, we promote circular manufacturing practices that consider the entire product lifecycle, from raw material procurement through to manufacturing, product use, and disposal. We are also pursuing initiatives based on the LIXIL Plastics Action Statement to reduce the amount of plastic used, recycle plastic, and develop alternative materials.

Initiatives to Achieve Our Vision

LIXIL has managed to reduce CO2 emissions from operational activities by a much larger degree than originally targeted in our five-year medium-term environmental plan through FYE2021 by pursuing energy-saving activities at our plants and offices, promoting technological development aimed at greater energy efficiency, and using renewable energy. We are also actively promoting the recycling of waste in order to reduce waste at our production sites worldwide, and we have seen particularly significant improvements in recycling rates in Asia.

Formulating New Medium-Term Targets

In FYE2022, we pursued initiatives in each focus area based on single-year targets and also analyzed and discussed the formulation of new medium-term targets, which then enabled us to compile new medium-term targets*1 in the area of climate change mitigation and adaptation. By FYE2031, we aim to reduce CO2 emissions from our business sites (Scope 1 and 2) by 50% (SBT 1.5℃ level) compared to FYE2019 and to reduce CO2 emissions form supply chains (Scope 3) by 30% (SBT WB-2℃ level)*2 compared to the same year.

In addition to the above-mentioned targets, we have actively provided products and services in Japan to help reduce Scope 3 emissions during product use, and we have set a target to increase the sales ratio of energy and water-saving faucets and water-saving toilets to 100% by FYE2031. In order to help promote the transition to a low-carbon society, we have also set a target to increase the sales ratio of high-performance windows for newly built detached houses to 100% by FYE2026. As of FYE2022, we have already increased that percentage to 80%. Meanwhile, we are also working with suppliers to reduce CO2 emissions from procurement by encouraging suppliers to cut CO2 emissions during their manufacturing processes and by using low-carbon raw materials and components, fewer resources to make products, and recycled materials.

We are working to determine medium-term targets for water sustainability and circular economy in FYE2023.

*1 Currently preparing for SBT revalidation of the renewed targets (as of July 29, 2022).

*2 CO2 emissions generated through energy consumed indirectly by LIXIL products, such as energy consumed to heat water for faucets and showers and energy relating to water supply and sewerage, are excluded from the reduction targets because it isn’t possible to reduce that energy to net zero just by improving the performance of LIXIL products.
