LIXIL makes pioneering water and housing products that solve everyday, real-life challenges, making better homes a reality for everyone, everywhere.
Progress in FYE2023
Buildings account for about 28% of the world's energy-related CO2 emissions, with residential sections alone accounting for 17%.*1 In order to realize our Zero Carbon and Circular Living environmental vision, LIXIL has designated climate change mitigation and adaptation as one of our focus areas and positioned that goal as a priority among our material issues.
We aim to reduce CO2 emissions to net zero by 2050 by reducing environmental burden of our operations, and providing environmentally friendly products and services. We are committed to the reduction of CO2 emissions, that are not limited to direct reduction of CO2 emissions from LIXIL's business. We also promote initiatives to contribute to the transition to a low-carbon society. Furthermore, we intend to support climate change adaptation by providing solutions, such as for dealing with natural disasters or for preventing indoor heatstroke.
To achieve our goals, we are taking a comprehensive strategic approach and pursuing medium-term targets through each of three phases: Our Operations, Our Value Chain, and Expanding Our Impact. We will go beyond simply fulfilling our corporate responsibility to minimize the environmental burden of our business and products, and also create new value in the environmental field together with all stakeholders in order to have an even greater positive impact on the global environment and society.
By FYE2031, we aim to reduce CO2 emissions from our business sites (Scope 1 and 2) by 50.4% compared to FYE2019. In order to minimize the environmental burden of our business activities, we are working to reduce CO2 emissions through thorough energy-saving activities at our factories and offices, and by using renewable energy, converting to fuels with low CO2 emissions, and shifting to electric power (electrification).
Aging aluminum parts using hydrogen combustion
We are striving to improve energy efficiency by identifying any issues with our production processes, reviewing facilities, and generally improving activities at each production site. All factories that manufacture GROHE products and all GROHE distribution centers have received ISO 50001 certification for their energy management systems.
LIXIL’s manufacturing processes use a lot of fuel to satisfy the need for heat when manufacturing products from materials, so we are working to reduce CO2 emissions generated by fuel usage. In the low-temperature range, we are actively converting from fuel to electricity and switching to renewable energy sources. We have also started to switch the fuel used at our Ariake Plant from petroleum-based fuels to natural gas. Using natural gas emits less CO2 during combustion and less nitrogen oxide (NOx), which is an air pollutant, and does not emit sulfur oxide (SOx).
However, we need to promote innovation for manufacturing processes in the high-temperature range that goes beyond conventional fuels and manufacturing methods. With that in mind, LIXIL has started considering innovations that incorporate new technologies such as hydrogen fuel conversion and carbon capture and utilization (CCU) that separates, captures, and effectively uses CO2, as well as the application of new technologies that are currently in the research stage, with a view to practically applying such technologies from 2030 onward. In FYE2023, we successfully completed hydrogen combustion tests at our Maebashi Plant.
While there are several major hurdles relating to the development of infrastructure for supplying hydrogen as a fuel, LIXIL has started technical verification relating to hydrogen procurement with the aim of establishing technologies across all processes from procurement through usage. Indeed, in verification tests on the surface treatment process of applying color to the aluminum parts being manufactured at our Oyabe Plant, we successfully recovered over 90% of the hydrogen generated.
Klaeng plant in Thailand
LIXIL is making the transition to renewable energy. That drive includes our membership of RE100, a global initiative of companies committed to sourcing 100% renewable electricity for their operations.
So far, we have successfully switched to renewable electricity at 14 production sites, six offices, 10 distribution centers, and 82 sales bases in Japan. Outside of Japan, in addition to all LIXIL International faucet fitting plants and distribution centers (10 locations in total), three plants in Mexico also switched to renewable energy. In FYE2023, our renewable energy ratio reached 25.0%, cutting annual CO2 emissions by 103,600 tons from the previous year.
In addition to purchasing renewable energy certificates, we started introducing solar power generation facilities at our manufacturing plants based on the on-site Power Purchase Agreement (PPA) model* that considers additionality, or the encouragement of further investment in renewable energy facilities. We are developing on-site PPAs inside and outside Japan. For instance, the two plants that produce GROHE products generate approximately 6,500 MWh of electricity. Our Klaeng plant in Thailand, one of the two GROHE plants, installed 3.2 MW solar panels on its rooftop, cutting annual CO2 emissions by approximately 2,400 tons. GROHE also installed new solar power generation facilities at its Hemer Plant in Germany in FYE2023. The area occupied by the solar power generation system at the Hemer Plant spans approximately 20,000 m2, making it the largest in the region, and the amount of power it generates annually is equivalent to roughly 20% of the plant’s annual electricity consumption. In Japan, we started operating an on-site PPA model at our Otani Plant and plan to launch a similar model at our Onomichi Plant in August 2023. In FYE2023, we introduced off-site PPA for the first time at our four plants in Mexico. We also operate megawatt-scale solar power plants that produce approximately 34,000 MWh of power per year at eight locations in Japan.
* A business model that enables PPA service providers to install solar power generation facilities on the premises and rooftops of buildings owned by electric power consumers, and to sell electricity generated from those facilities to electric power consumers.
By FYE2031, we aim to reduce Scope 3 CO2 emissions by 30% (SBT WB 2°C level*) compared to FYE2019. Product use and procurement account for a large proportion of Scope 3 CO2 emissions across the LIXIL value chain, so, in addition to our efforts to increase the energy-saving features of our products, we are also working with suppliers and other companies to reduce CO2 emissions in the procurement and distribution phases. We reduce CO2 emissions across the entire lifecycle of our products and services by using more low-carbon raw materials and components, utilizing recycled materials, creating resource-saving products, and designing products with a view to extending product life and facilitating product reuse.
* The well below 2°C target of the Science Based Targets initiative (SBTi) to cap global temperature increase well below 2°C compared to pre-industrial temperatures
Cooperating with suppliers is vital when seeking to reduce CO2 emissions in the procurement stage. We ask our suppliers for their full comprehension and cooperation in our procurement activities that are conducted internationally in accordance with LIXIL’s environmental activities and Supplier Code of Conduct, along with the additional Green Procurement Guidelines in Japan.
From FYE2023, we began engaging with suppliers that constitute the top 80% of total CO2 emissions from procurement to help us grasp current conditions across the entire value chain and reduce CO2 emissions effectively. We conducted surveys of suppliers that are particularly significant when it comes to reducing CO2 emissions to get a better understanding of total CO2 emissions and the setting of CO2 reduction targets. Going forward, we intend to increase communication based on the survey results to ensure stable supply of raw materials and responsible procurement, to facilitate the acquisition and utilization of supplier data, and to strengthen partnerships to help reduce CO2 emissions from procurement. We will also accelerate efforts to achieve effective reductions in CO2 emissions across our value chain by utilizing more low-carbon raw materials and components, and recycled materials.
In FYE2023, we increased operation of our round-trip shipping container program that allows shared use of logistics equipment with other companies. We achieved round-trip use of 826 containers in total with our partners, reducing CO2 emissions by approximately 107 tons a year.
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. In FYE2023, the initiative expanded the target area to cover all across Hokkaido, and successfully reduced the combined driving distance by partner companies by approximately 590,000 kilometers a year and CO2 emissions per tonne-kilometer by 21%.
LIXIL helps reduce CO2 emissions by offering energy-saving toilet and kitchen-related products. For example, one of our toilet products, the Satis S Type Toilet, reduces CO2 emissions by 111 kg per year by offering various functions including the Super Power-Saving Function, which automatically lowers the temperature of the toilet seat and hot water to conserve energy when not in use, and the One-Touch Power-Saving Switch, which enables the user to turn off the heater for set periods and consequently conserve energy.
