King Charles and Prince William recently made a rare joint appearance at the Natural History Museum in London, an event held six weeks prior to the COP30 climate change summit slated for Belém, Brazil. During the reception, a significant announcement was made: Prince William will be representing his father, King Charles, at the upcoming summit. This expanded role for Prince William includes a scheduled trip to Brazil for the Earthshot Prize Awards ceremony in Rio de Janeiro on November 5, where he will engage in various environmental activities before proceeding to Belém to deliver a speech at COP30, marking a notable expansion of his responsibilities on the global stage.

King Charles, 76, is currently undergoing cancer treatment and has previously led the royal presence at these crucial climate events. His attendance at COP26 in Glasgow marked William's first international travel for a COP summit, though he has attended previously. The London event, co-hosted by Dr. Doug Gurr of the Natural History Museum and Deputy Prime Minister David Lammy, provided an opportunity for Charles and William to connect with various changemakers. Attendees included delegates from finance, business, science, and education sectors, as well as former Prime Minister Theresa May, and had the chance to discover cutting-edge climate solutions developed in the UK.

Dr. Doug Gurr emphasized the critical need for collective action, stating, "We need everyone in society to get on board to tackle the twin challenges of biodiversity loss and climate change." He highlighted the palpable commitment to act for the planet, ranging from royal and governmental support to the efforts of school students transforming their grounds for wildlife. King Charles's history with COP summits includes being compelled to skip COP27 in Egypt in 2022 due to government guidance during Liz Truss's premiership, despite his eagerness to attend. He subsequently delivered the opening speech at COP28 in Dubai in 2023, where he warned that global climate objectives were "dreadfully far off track." However, he was absent from COP29 in Azerbaijan in 2024 following his cancer diagnosis.

Both King Charles and Prince William are vocal advocates for addressing climate change. Reinforcing this commitment, it has been confirmed that Charles's decades-long initiative to harmonise nature and humanity will be featured in an upcoming Amazon Prime series. His Majesty expressed his "deepest wish" that this programme will inspire new audiences to embrace his environmental principles and underscored the unprecedented importance of global efforts to protect the planet. The documentary, provisionally titled "Finding Harmony: A King's Vision," will delve into Charles's personal reflections on his lifelong dedication to fostering a sustainable future, portraying an inspiring narrative of "hope and resilience."

Created by Passion Planet in collaboration with The King's Foundation for Amazon MGM Studios, the documentary is set to debut exclusively on Prime Video across more than 240 nations and regions globally in early 2025. King Charles shared his hopes for the film, stating, "This film will, I hope, demonstrate just some of the remarkable work being done around the world to put Harmony into practice, from the forests of Guyana to sustainable communities in India – and, closer to home, through the work of my King's Foundation at Dumfries House and Highgrove." He concluded by reiterating the paramount importance for the world to unite in protecting and prioritising our planet and restoring our relationship with it.
