The Danish sustainability indicators
Green goods and services are products or services that have a direct environmental or resource-saving purpose, for example, wastewater treatment and production of wind turbines, as well as products that are clean and/or resource-efficient, so that they pollute and/or consume less than other products with the same main purpose, for example, production of low-energy houses.
