Climate change activist Greta Thunberg is planning to sail back to Europe on Wednesday aboard a 48-foot catamaran.

The 16-year-old Swedish activist will hitch a ride on the large sailboat with an Australian family of three, including an 11-month-old baby boy, in an effort to make it to the next round of United Nations-sponsored climate talks in Spain, The New York Times reported.

“I decided to sail to highlight the fact that you can’t live sustainably in today’s society,” Thunberg told the NYT. “You have to go to the extreme.”

Thunberg, who has become a bit of a celebrity, has been in the U.S. for about three months since she arrived in New York via a racing yacht in August.

But unlike her first trip across the ocean, this time the boat has an important amenity: a toilet. Thunberg, however, wasn’t too concerned about the convenience that many take for granted, according to The Associated Press. (For the record, her first boat only had a bucket).

“There are countless people around the world who don’t have access to a toilet,” she told the AP. “It’s not that important. But it’s nice to have.”

Thunberg’s ride across the ocean is expected to take two to four weeks, which the teen chooses over flying because of the carbon footprint. The catamaran, La Vagabonde, which has solar panels and hydro-generators, belongs to an Australian family that travels the world and documents it on YouTube, according to reports.

“I’m looking forward to it, just to be able to get away and recap everything and to just be disconnected,” she told the AP.

Thunberg has become powerful force in the fight against climate change and has motivated people to take up the cause by including influencing the Global Climate Strike in September, and inspiring 10-day bike tours around the world, including in Vietnam, Morocco, and Thailand.

While she was in the States, Thunberg made the rounds in the American media circuit including appearances on "The Ellen DeGeneres Show" and "The Daily Show" with Trevor Noah.

And what’s next for the world-traveling Thunberg after Spain? She wants to go home to Stockholm and hug her two dogs, of course.

“Traveling around is very fun and I’m very privileged to have the opportunity to do so, but it would be nice to get back to my routines again,” she told the NYT.
