Eco-friendly Mark System

Eco-friendly Mark System

Eco-friendly Mark System awards eco-friendly mark to products that causes relatively less contamination or save resources in production and consumption to provide consumers with accurate environmental information regarding each product and encourage companies to develop and produce eco-friendly products that satisfy consumer preferences.
Initiated in Germany in 1979, this System has been successfully adopted by about 40 countries in the EU and Northern Europe and including Canada, USA, and Japan. Korea has been implementing it since April 1992.
Eco-friendly Mark System aims to provide accurate environmental resources to consumers so that companies and consumers can produce and consume eco-friendly products. Through this system consumers are encouraged to participate in environmental preservation activities and companies are encouraged to develop and produce eco-friendly products and technologies that satisfy consumers’ desire to purchase eco-friendly products for sustainable production and consumption.

Eco-friendly Mark Managing Institutions

Eco-friendly Mark System is operated by various forms of institutions, including governments (EU, Czech Republic), private organizations (USA, Sweden), and partnership of government and private organizations (Germany, Japan), according to the cultural, economic, and social circumstances of each country. In Korea, it is managed by the Ministry of Environment and KOECO.

Certification Criteria

Definitions
  • “Volatile organic compounds (VOCs)”refer to liquid or organic compounds that constantly volatilize in air due to certain temperature and pressure conditions.
  • “VOCs content”refers to the mass of volatile organic compounds in a unit of volume of paint measured in given conditions. These conditions refer to the value diluted and measured at maximum dilution rate in product manual.
    Note) Here, all organic compounds whose boiling point is below 250℃ are considered volatile organic compounds.
  • “VOCs emissions”refer to the amount of volatile organic compounds emitted from a unit of area within a unit of time in given conditions.
    Note) Here, any material in between n-hexane and n-hexadecane in the chromatogram of Gas Chromatograph with mass analyzer is considered VOCs.
