Swedish climate activist Greta Thunberg has said that she would cross the Atlantic on a racing sailboat to attend a UN climate summit in New York in September.
"I've been offered a ride on the 60 ft (18-metre) racing boat Malizia II. We'll be sailing across the Atlantic Ocean from the UK to NYC in mid August," the 16-year-old said on Twitter.
It will be her first visit to the US since she launched her environmental drive a year ago.
Ms Thunberg, who has inspired thousands of her peers in many parts of the world to press their elders to act on climate change, refuses to fly owing to the negative impact on the environment.
German Boris Herrmann and the Monaco-based founder of the Malizia team Pierre Casiraghi will steer the boat, which is to carry a sail marked "#Fridays for future".
The phrase stems from Ms Thunberg's decision to skip school on Fridays so she could push for action against climate change in front of the Swedish parliament.
"After months of research and considering different options for her journey, Greta will sail across the Atlantic in a zero-carbon racing boat called Malizia II, a foiling sailboat built in 2015, which is fitted with solar panels and underwater turbines to generate electricity on board the vessel," Mr Herrmann said on his website.
Once in the US, she is to take part in "large-scale climate demonstrations on September 20 and 27 and speak at the United Nations Climate Action Summit, hosted by Secretary General Antonio Guterres," he added.
Ms Thunberg also planned to visit Canada and Mexico, and attend a UN climate conference (COP25) in Santiago, Chile, in early December, Mr Herrmann said, with other South American stops also planned.
Her spokesman could not be reached for confirmation of the complete itinerary, but people close to Greta have already said that she would attend the COP25 conference.
The Guardian newspaper said she would also be accompanied by her father Svante, and a filmmaker.
Casiraghi, the grandson of Monaco's late Prince Rainier III and US-born actor Grace Kelly, has said the boat's name was taken from the Moneguesque language and meant "the wily one."
