Environmentally friendly (also eco-friendly, nature friendly, and green) are terms used to refer to goods and services, laws, guidelines and policies claimed to inflict minimal or no harm on the environment.^[1] Companies sometimes use these terms to promote goods and services by making environmental marketing claims and with eco-labels.

Because there is no accepted definition nor international standard for this concept, the International Organization for Standardization considers such labels too vague to be meaningful.^[2
