Enhancing Eco-friendliness of Products

When consumers use Coway’s products, energy is consumed and water is used. This has an environmental impact. Coway therefore develops products with enhanced energy efficiency and reduced water usage to minimize our products’ impact on the environment.

Development of Products with Enhanced Energy Efficiency

Coway develops and applies vacuum insulation material application technology to products for the enhanced energy efficiency of hot and cold-water purifiers. We also increase energy efficiency in innovative ways by launching products using instant heating and semiconductor cooling technology.

  • 1) Water footprint : Measures the total amount of water directly and indirectly used to produce the goods and services we use, over the entire lifecycle from the acquisition of raw materials to production, distribution, use, and disposal. The water footprint is assessed according to the requirements of ISO 14046 of the International Organization for Standardization.
  • 2) Carbon neutral product certification: Granted to products whose company has purchased carbon credits equivalent to the amount of greenhouse gasses emitted throughout the products' lifecycle, from the acquisition of raw materials to their production, distribution, use, and disposal, or products that have achieved zero (0) carbon emission by greenhouse gas reduction activities.
  • 3) Carbon Balloon : While the Carbon Reduction Label calculates the carbon footprint of a product over its entire lifecycle based on certification standards in Korea, the Carbon Balloon is an international carbon reduction label certification granted by calculating carbon emission over the lifecycle of a product. It is based on stricter ISO14044 & PAS 2050 standards.
