Prince Harry asked to be addressed as just "Harry" during his appearance at the Edinburgh International Conference Centre on Wednesday to speak at the Travalyst event.

The Duke of Sussex insisted to be called just by his name, according to host and former Labour adviser, Ayesha Hazarika. Instead of being introduced as "Sir" or "His Royal Highness," he wanted to be welcomed at the event as just "Harry."

"He's made it clear that we are all just to call him Harry. So ladies and gentlemen, please give a big, warm, Scottish welcome to Harry," ET Canada quoted Hazarika as saying, when she introduced the royal to the stage.

At the Travalyst event, Prince Harry talked about Scotland's importance in setting an example to the U.K. and the rest of the world about green living. He wanted to hear about what the country is doing to promote sustainability in order to protect the environment.

"We want to hear truths and perspectives from across the industry. We don't need to reinvent the wheel, a lot of great work has already been done. But our research again shows that many of these endeavours have failed to reach the consciousness of consumers," the royal said, according to The Guardian.

Today, The Duke of Sussex is in Scotland – one of the world’s fastest growing tourist destinations - to hear what they’re doing to put sustainability at the forefront of holidays that protect the environment and support local communities. The number of tourists globally is rapidly rising, and based on an increasing desire from travellers, The Duke’s international partnership Travalyst is working to ensure the industry can better support communities that face increasing challenges of overcrowding, pollution, and the climate emergency. Supporting these communities means preserving these destinations for everyone. By harnessing the power of travel, which accounts for 1 in 10 jobs globally, generating newrly $9 trillion annually, and is at the heart of connecting people and culture, tourism can lead the way in supporting communities and protecting the environment. At a summit in Edinburgh, representatives from the Scottish tourism and travel sector will join event partners @visitscotland and @eic_uk to help test and develop the latest work. Founding partners @Bookingcom, @Skyscanner, @Trip, @TripAdvisor and @Visa_US are working with The Duke, backed up by consumer demand, to transform travel and tourism globally so that every holiday people take, every trip they book, can have a positive impact on the destinations they visit.
