Sustainitarian 

Person who will not eat meat unless it is sustainably derived. This means the person will only eat free-range meat, grass-fed (beef), with no additives.

For his new year's resolution, Alex decided to go sustainitarian. He always asks the waiter if the meat is free-range, oftentimes embarrasing the restaurant. To this day he has had to settle with vegetarian options.

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".
