reports that beef production is one of the largest carbon-driving processes in the food industry, which as a whole is responsible for a third of the global carbon emissions.

In fact, raising beef for meat generates ten times more emissions than growing hen for the same purpose, as cattle are well-known for their rich-methane releases.

Professor Diego Rose, senior author of the Tulane University study which also weighs up different diets’ nutritional quality, said that "climate change is arguably one of the most pressing problems of our time, and a lot of people are interested in moving to a plant-based diet."

"That would reduce your footprint and be generally healthy", he argues, as he also states that "there's a way to improve your health and footprint without giving up meat entirely."

Many people change their diets throughout their lifetime, which is why it is important to know in which way each dish affects the environment.

A vegan diet is one of the best if you truly care for the environment, as it implies not eating any animal-related products, and it has an impact of 0.7 kg per 1.000 calories consumed.

A keto diet, on the other hand, which consists of eating high fat and low carb products, is among the least sustainable ways of feeding yourself, as it generates nearly 3 kg of carbon emissions per 1.000 calories eaten.

The paleo diet, which excludes beans and grains in favor of meat, nuts and vegetables, has the lowest nutritional score and a high carbon footprint, overall, at 2.6 kg per 1.000 calories consumed.

The study ranked vegetarian and pescatarian diets as the best with regards to the environment and nutritional value after the vegan one.

An omnivore diet was reported by 86% of the 16.000 survey participants and it is the middle of the road when it comes to diet quality and also carbon emissions.

If just a third of participants who have omnivore diets were to switch to a vegetarian one, it would be the equivalent of cutting 547 million kilometers traveled by passenger vehicles.
