Something that is "eco-friendly" is safe for the environment. Recycled products can be called "eco-friendly". A car that uses less gasoline is also "eco-friendly".

You wouldn't say that a person is "eco-friendly". Only products and people's actions can be eco-friendly. To describe a person who is careful to protect the Earth, use the phrase "environmentally conscious".

That's not very environmentally conscious of me, is it?
