Tesla's cars are already eco-friendly, but they just got a little more vegan-friendly.

Yes, vegan-friendly.

The electric car maker is now letting customers order its new Model X with synthetic leather seats and accents, according to a report from the New York Times.

Tesla is calling the new option "Ultra-White."

Tesla already offers its customers the option of cloth seats. But other luxury automakers including BMW and Mercedes-Benz offer a synthetic leather option.

And considering the company's whole premise is about limiting emissions, the move makes sense.

According to the Food and Agricultural Organization of the United Nations, livestock around the world account for about 14.5% of all greenhouse gas emissions caused by humans.

The company came under pressure to increase its offerings in June of last year at a shareholders meeting. Two proposals were made on the topic. The first was to completely stop using animal-based products. And the second was to decrease the use of the products, eventually discontinuing them completely by 2019.

At the time, though, the board recommended a vote against both proposals saying that such a move would "impede or delay" the company from other priorities.
