The Duke of Cambridge spoke with pride last week at the summit in Glasgow about the work being undertaken by the finalists and winners of his inaugural Earthshot Prize Awards. One green entrepreneur being promoted by Prince William is Sam Teicher, who spoke to US Special Presidential Envoy for Climate John Kerry. Mr Teicher, who is working to save coral reefs from damage, also got to speak to the Prime Ministers of Australia and the Bahamas.

       Speaking to People magazine, Mr Teicher said: "It wasn't just a case of 'please meet these people and do your own thing,' he was hauling them over to come to talk to us.

       "He was making sure they were there to help us."

       Mr Teicher helms Bahamas-based company Coral Vita along with his colleague Gator Halpern.

       The company uses novel ways to grow coral and rebuild nature's natural sea defences.

       The company took top honours in the Revive Our Oceans category, going on to win $1.3 million from Earthshot to develop their project over the next 10 years.

       According to Teicher, the prince, 39, was asking the Prime Ministers and Envoy Kerry how Teicher and Halpern could help their specific needs, telling them: "You make those asks and listen to Sam."

       Speaking about Prince William's communicative method at the COP26 summit Mr Teicher said that the Duke of Cambridge "cut through traditional protocol".

       Mr Teicher said: "He was incredibly direct and forthcoming and generous.

       According to the Climate Action Tracker (CAT), the COP26 talks "have a massive credibility, action and commitment gap".

       The Glasgow summit is seen as crucial for curbing climate change.

       The analysis has slightly improved as at the Paris climate summit in 2015, Climate Action Tracker estimated the policies put the planet on track to warm by 3.6C.

       Greenpeace International's executive director Jennifer Morgan said: "This new calculation is like a telescope trained on an asteroid heading for Earth.

       "It's a devastating report that in any sane world would cause governments in Glasgow to immediately set aside their differences and work with uncompromising vigour for a deal to save our common future."
