sustainability suit 

The most environmentally sustainable attire you can wear is no clothes at all, hence known as a ‘sustainability suit’ (formally known as the ‘birthday suit’).

Sustainatarian 

Broadly speaking, the term sustainatarian applies to decision-making based on principles of environmental sustainability and fairness to both humans and animals.

Different than a vegetarian (who may eat factory-farmed dairy), or a vegan (who will not eat animal products of any kind) a "sustainatarian" is a person who eats a mostly plant-based diet with occasional sustainable meat, meaning that it is locally and humanely raised. The term also refers to buying fair trade, organic, recycled, reused and/or reusable food, clothing and consumer goods wherever there is a choice.

"Being a strict sustainatarian, I only buy beef if I can get it from pastured cows raised comfortably on a local small-scale farm".
