SOMERVILLE, Mass. (AP) -- The Prince and Princess of Wales got a first-hand look at some groundbreaking innovations during a visit to a green technology startup incubator in suburban Boston on Thursday as the royal couple looks to foster new ways to address climate change.
William and Kate, who are making their first overseas visit since the death of Queen Elizabeth II, were welcomed by hundreds of cheering onlookers as they entered Greentown Labs in Somerville.
They were greeted by CEO Emily Reichert, Mayor Katjana Ballantyne as well as Joe Curtatone, the former mayor of the city just north of Boston who is now the president of the Northeast Clean Energy Council. William wore a gray suit with a burgundy sweater. Kate wore a burgundy suit by Roland Mouret, with a blouse by Burberry and earrings by Daniella Draper.
Since its 2011 founding, Greentown, the largest climate technology startup incubator in North America, has supported more than 500 companies that have created more than 9,000 jobs.
The three-day visit started Wednesday with a reception at Boston City Hall and a trip to a Boston Celtics basketball game. It culminates Friday with the awarding of the prince's signature Earthshot Prize, a global competition aimed at finding new ways to protect the planet and tackle climate change.
On Thursday at Greentown, the royal couple chatted to Shara Ticku, CEO of c16 Biosciences, a company developing decarbonized alternatives for the consumer products supply chain, starting with a sustainable alternative to palm oil.
At Open Ocean Robotics, CEO and cofounder Julie Angus told the prince and princess about their solar-powered autonomous boats, which provide real-time information about the oceans. Angus has a computer and monitor on her table, showing data of a real boat out in the harbor in Victoria, British Columbia, where the company is based.
William and Kate also met with Earthshot CEO Hannah Jones, who led them to four past Earthshot winners or finalists, including Vaitea Cowan, co-founder of AEM Electrolysers, which turns renewable electricity into green hydrogen.
Upon their departure from Greentown Labs, Kate received flowers from 8-year-old Henry Dynov-Teixeira, who was wearing a King's Guard costume.
Thursday's agenda also included a visit to Roca Inc., an organization that seeks to improve the lives of youth and young adults by addressing issues such as poverty, incarceration and trauma from urban violence; and a visit to the Boston waterfront, which is threatened by rising sea levels.
The royal couple's first trip to the U.S. since 2014 is part of the British royal family's efforts to change their international image. In the wake of Elizabeth's death, King Charles III, William's father, has made clear that his will be a slimmed-down monarchy, with less pomp and ceremony than its predecessors.
That includes a focus on the Earthshot Prize, which offers 1 million pounds ($1.2 million) in prize money to each of the winners of five separate categories: nature protection, clean air, ocean revival, waste elimination and climate change. The winners and all 15 finalists also receive help in expanding their projects to meet global demand.
