Both William and Harry are longtime environmental advocates, much like their father, Prince Charles. Amid the news of William’s stateside appearances for Earthshot, The Associated Press reported Friday that the Duke of Cambridge’s Royal Foundation invests money with JPMorgan Chase, a bank that heavily backs fossil fuels. The Royal Foundation told the AP by email that it had followed and even surpassed ethical investing guidelines set by the Church of England. “We take our investment policies extremely seriously and review them regularly,” the foundation said.
