Green

Adjective

The quality of being conscious about Environmental Impact and reducing that Impact. Also known as "Environmentally Friendly".

💡To Note:

Being "Green" is a very, very broad term and is used as a catch-all for being conscious about environmental impact.
"Green" can also be used to denote low-carbon industries, for instance "Green Technologies".
Confusingly, sometimes, people also use the word "Clean" in the same way. For example: Clean Energy and Green Energy refer to exactly the same thing... low-carbon energy.
