The Duke of Sussex has unveiled a new promotional film for Travalyst, his sustainable travel initiative established in 2019, timed to coincide with London Climate Action Week.
The video appearance came after his brother Prince William made his own environmental engagement earlier this week.
In the short film, Harry delivered a stark assessment of the tourism industry's current position. "Today, travel stands at a crossroads," he stated in the footage.
The duke warned that the sector "could be a catalyst for positive change, but also a source of environmental strain, driving emissions, overwhelming destinations, depleting the natural world it depends on."
According to Travalyst, the new film demonstrates how the organisation aims to construct an alternative approach to travel sustainability.
Harry outlined the transformation he envisions: "From tangled, fragmented data to a single source of truth.
"From hidden impacts to trusted, transparent choices.
"From siloed efforts to a powerful collective."
The duke continued by describing a shift "from small tweaks to accelerating systems change" and moving "from travel stuck in the past to travel that unlocks action from travellers, businesses, and communities."
He emphasised the potential for transformation, declaring: "Together, we have the power to change travel for good."
The Duke of Sussex is expected to return to Britain next month for the Invictus Games 2027 One Year To Go celebration in Birmingham.
Reports indicate that Harry will be accompanied by his wife, Meghan Markle, and their two children, Prince Archie and Princess Lilibet, marking a significant family visit to the UK.
The Invictus Games, Harry's international sporting competition for wounded veterans, will be hosted in Birmingham in 2027, with next month's event serving to build momentum ahead of the tournament.
The visit will come just weeks after his latest Travalyst video appearance promoting environmental causes.
Meanwhile, Prince William attended the Earthshot Prize Impact Assembly at Guildhall in central London on Tuesday, where he expressed heightened optimism about environmental progress.
"Solutions are working. Capital is moving. Policy is shifting," the future king told attendees gathered to celebrate the achievements of prize-winners in planetary restoration efforts.
Now at the midpoint of his decade-long Earthshot initiative, William reported that 75 finalists have collectively protected and restored 1.4 million square kilometres of land, ocean and coastline, conserved 21 million tonnes of water, and eliminated nearly half a million tonnes of waste.
The 2026 awards ceremony will take place in Mumbai this November.
