LG Electronics (LG) has announced new measures to reduce plastic consumption and carbon emissions in its commercial 4-way system air conditioners. The initiative aligns with the company’s Better Life for All ESG vision.

TÜV Rheinland, a global testing and certification organization, confirmed that LG’s updated production process has lowered carbon emissions to 14.85 kilograms of CO₂ equivalents per unit. The reduction is mainly due to a new material used for the air conditioners’ exterior panels.

LG now uses a foaming injection molding process. Nitrogen gas is injected into the mold, creating bubbles in the material. This reduces plastic use by about 900 grams per unit. Additionally, LG replaced Acrylonitrile Butadiene Styrene (ABS) with Polypropylene (PP), which has a smaller carbon footprint.

• The changes are expected to cut plastic consumption by around 270 tons annually.
• Carbon emissions are projected to fall by over 4,400 tons per year, comparable to what a 30-year-old pine forest covering 580 soccer fields absorbs.

LG began applying the method to 4-way system air conditioners in June. The company plans to expand it to other residential and commercial models.

The company aims to reduce greenhouse gas emissions by 54.6% by 2030 compared to 2017 levels. LG will integrate high-efficiency equipment and renewable energy in its manufacturing processes.

Core Tech, LG’s proprietary technology, includes inverter motor technology that adjusts motor and compressor speeds in real time to minimize energy waste. The company also launched an inverter scroll chiller using R32 refrigerant, which has a Global Warming Potential (GWP) about 30% lower than R410A.

Bae Cheung-hyun, head of the System Air Conditioners Business at LG ES Company, said, “The new material and manufacturing process underscores our efforts to minimize environmental impacts. LG will continue to leverage innovative technologies to develop eco-conscious air conditioners for a healthier planet.”
