It would be "very powerful" if King Charles attended the COP27 climate summit in Egypt, U.S. special climate envoy John Kerry said, adding that the British monarch's credibility and leadership on environmental issues would make a difference.
Charles, who became king last month following the death of his mother Queen Elizabeth, spoke at the opening ceremony of the 2021 summit in Glasgow, which he described as a "last chance saloon" to save the world from climate change.
