According to a palace report on Wednesday, the Duke and Duchess of Cambridge's trip in March cost the British taxpayer $275,000. William and Kate's tour of Belize, Jamaica and The Bahamas was the most expensive tour by the royal family in the recent financial year, which just came to a close. While the tour was taken in honor of William's grandmother Queen Elizabeth's Platinum Jubilee, the couple encountered mounting tensions in the Caribbean nations where the Queen remains head of state. The tour saw protests over colonialism and calls for dropping the Queen as head of state. Last week, William said in a groundbreaking address that he and Kate are learning how the "past weighs heavily on the present" amid the controversy that followed their tour.

The heir to the throne was on hand for Barbados' transition ceremony as they removed Queen Elizabeth as head of state and swore in the island country's first president. The Queen's use of the Royal Train (which she took to Scotland this week) to Cornwall to host G7 political leaders last June cost $38,400. The report only includes the journeys costing more than $18,100. There were also 179 helicopter flights by members of the royal family (totaling $1.1 million) and 24 charter flights (costing $341,000). It was also revealed that the royal family undertook more trips and tours in the past fiscal year than the previous year due to the easing of the COVID-19 pandemic.

Ian Vogler-Pool/Getty Royal aides recognize that there is a "tension" between the royal family's desire to cut carbon emissions and their environmental work — like William's Earthshot Prize and Charles' sustainability and climate control efforts. "Travel is an important part of members of the Royal Family, whether it's visiting communities or overseas travel at the requests of government. It is part of the core role of members of the Royal Family," a senior royal source says. "We will take advantage of some of the things we have learned during the pandemic like virtual engagements, but there isn't any substitute for the physical engagements."

To combat this, the royals are using biofuels on the Royal Train. Charles is also behind efforts to use sustainable aircraft fuel. An aide praises the Royal Air Force as being "brilliant partners" when the royals use the RAF Voyager jet. Every royal flight the Voyager makes from the U.K. will be with sustainable fuel. All travel emissions are also offset — something Charles has led the way on. "There is a conflict to being an environmental champion with the official travel," the royal aide says. "That is tricky but this is the way he is trying to reconcile it."
