Kate Middleton and Prince William Continue U.S. Trip with Special 'Green' Outing

After sitting courtside at the Celtics game on Wednesday night, Kate Middleton and Prince William were off and running on Thursday morning for a busy day of outings as they continue their three-day visit to Boston.

The Prince and Princess of Wales visited Greentown Labs in Somerville where they learned how the organization is contributing to global efforts to address the climate crisis. The visit is the perfect outing for the couple ahead of Friday's Earthshot Prize Awards ceremony, which will celebrate global efforts being made around the world to protect the environment.

Kate and Prince William, both 40, also met with representatives from some of the start-ups within the Greentown Labs community to hear about the latest innovative developments in climate technology. These innovators were themed in alignment with the five Earthshot Prize categories: Fix Our Climate, Protect and Restore Nature, Build a Waste Free World, Revive Our Oceans and Clean Our Air.
