Eco-friendly describes products, services, or practices that cause little or no harm to the environment.
[adjective]
The term is often used in marketing to indicate reduced environmental impact, though it should be supported by measurable actions or certifications to avoid misleading claims.
Example: A company that uses renewable energy to power its manufacturing facilities can describe its operations as eco-friendly.
