Royals Kate Middleton and Prince William Grill Veggie Burgers and Sow Wildflower Seeds in Eco-Friendly Scout Meet-Up The couple traveled to Scotland with Prince Charles and Camilla, Duchess of Cornwall for the COP26 United Nations Climate Change Conference By Stephanie Petit Stephanie Petit Stephanie Petit is a Royals Writer and Reporter at PEOPLE. People Editorial Guidelines Published on November 1, 2021 12:00 PM Share Tweet Pin Email Kate Middleton and Prince William are talking climate change with the next generation. The couple kicked off their visit to Scotland for the 2021 United Nations Climate Change Conference, also known as COP26, on Monday. Their first outing brought them to Alexandra Park Sports Hub in Dennistoun to meet with young Scouts and hear how about their #PromiseToThePlanet campaign. Kate, who is joint president of The Scout Association alongside the Duke of Kent, and William took part in activities that demonstrate how scouting is helping to equip young people with the skills to tackle climate change. They grilled up veggie burgers, made and scattered wildflower seed 'bombs,' and mastered the basics of bicycle maintenance. They also met 12-year-old Lewis Howe, one of the 26 #OneStepGreener Ambassadors recently announced by the U.K. Government. Through scouting, Lewis is challenging all schools around Scotland to reduce food waste by using surplus food to create meals for those in need using environmentally friendly packaging. The couple were dressed casually for the afternoon outing. Kate wore what appeared to be a Ganni vest made from 100% recycled polyester over a monochromatic jeans-and-turtleneck look rounded off by a red, white and blue U.K. Scouting neckerchief. And William wore a button-down collared shirt under a green sweater, accented by a poppy pin in solidarity with veterans ahead of Remembrance Day on November 14, over navy pants and brown shoes.

Queen Elizabeth will address the assembled delegates via a recorded message as part of the reception. The Queen, 95, announced last week that she "regretfully" decided not to attend the conference after being advised by doctors to rest. After an overnight hospitalization on October 20, Buckingham Palace announced Friday that the monarch has been "advised that she should continue to rest for at least the next two weeks." She plans to the National Service of Remembrance on Remembrance Sunday on November 14 and will continue to undertake light duties from Windsor Castle.
