Reducing CO2 emissions with PremiAL

CO2 emissions from aluminum extrusion manufacturing to processing and assembly
(Per kilogram of aluminum)

graph showing a 50% reduction in CO₂ emissions from aluminum extrusion manufacturing to processing and assembly by replacing primary raw materials with recycled material

Manufacturing aluminum extrusions from recycled material generates approximately 50% fewer CO2 emissions*2 than using primary raw materials.

*1 Of PremiAL raw materials (LIXIL-manufactured 6063 alloys, dissimilar alloys, and purchased billets), the LIXIL-manufactured 6063 alloys utilize 60% or more recycled aluminum. Dissimilar alloys and purchased billets are excluded from the calculation.

*2 As calculated by LIXIL

*3 CO2 emissions calculated to include LIXIL-manufactured 6063 alloys, dissimilar alloys, and purchased billets. Third-party SuMPO EPD verification obtained. See the SuMPO EPD website (https://ecoleaf-label.jp) for details on this EPD.

PremiAL produced at all manufacturing plants* worldwide

Vietnam Plant、Thailand Plant、Oyabe Plant、Shimotsuma Plant、Ariake Plant

The PremiAL series can be mass produced at all aluminum extrusion manufacturing plants* worldwide.

*As of September 2025, at factories in Thailand, Vietnam, Oyabe, Shimotsuma, and Ariake

PremiAL has obtained the third-party SuMPO EPD verification

SuMPO EPD JAPAN VERIFIED

PremiAL has received third-party SuMPO EPD verification for visualizing the environmental impact of building materials used in construction.

  • PremiAL has undergone third-party verification in accordance with Environmental Product Declaration (EPD) standards for greenhouse gas (GHG) emissions up to the aluminum extrusion production stage.
    See the SuMPO EPD website (https://ecoleaf-label.jp/) for details on this EPD.

  • The environmental information disclosure program operated by the Sustainable Management Promotion Organization (SuMPO) complies with ISO14025 (Type III Environmental Declarations).

Choosing LIXIL products helps reduce the whole-life carbon emissions of buildings

Accelerating efforts to reduce the whole-life carbon of buildings

Globally, the buildings construction sector is taking greater action to reduce whole-life carbon emissions
—both embodied and operational carbon—in a move toward decarbonization.

Buildings currently account for
37%* of global CO2 emissions

*Source: IEA World Energy Statistics and Balances

Embodied carbon

Construction-related CO2 emissions from raw material sourcing and processing to shipping, construction, renovation and disposal

A key indicator in recent years
Can be reduced by choosing recycled and low-carbon materials
Embodied carbon 50%, Operational carbon 50%

Operational carbon

CO2 emissions from energy used during building occupancy and operation

Can be reduced through adoption of high-performance windows, ZEH/ZEB and energy-saving equipment
