NEW: The Prince of Wales has arrived in New York 🇺🇸🗽
Prince William flew commercially to Newark airport. When he landed he said: "It’s so good to be back in United States. No one does optimism and ingenuity like the American people, so it’s only right we unveil this year's Earthshot finalists in New York City.
"80 years ago, the world came together in this great city to find a new way, through the UN, to solve our shared challenges.
"I know our generation can take the bold action we need to make changes towards a healthy and sustainable world. The challenge may feel huge, but as John F Kennedy taught us, we rise to the challenge not because it is easy, but because it is hard. And vital."
