Low-carbon tourism involves protecting tourism, promoting sustainability in the industry and generating tourism that supports local communities. “China is a classic example. It's at the forefront of sustainable tourism and reducing carbon emissions,“ Fernando said.

　　He added that many developed economies are adopting similar practices, understanding the importance of decarbonization not only from tourism but also from a national perspective.

　　Low-carbon tourism could be achieved by ensuring all tourist attractions, facilities and service providers cut their emissions. In so doing, tourism operators would also cut their costs, increase their profits and help improve general economic health, he said.

　　According to Yu from Hong Kong, to achieve low-carbon tourism it is important to reduce energy consumption and carbon emissions, which arise from transportation to sightseeing activities and accommodation. “Promoting eco-friendly transportation options, such as electric or hybrid vehicles, is definitively a consideration,“ Yu said. “Hopefully, we can see more sustainable accommodation options, such as green hotels and eco-lodges available in the future.“

　　The environmental expert advocated practices such as reducing waste and promoting recycling. “Tourists should be encouraged (to show) responsible travel behaviors, such as reducing single-use plastics and respecting the local environments,“ he said.

　　Christine Loh, chief development strategist at the Hong Kong University of Science and Technology's Institute for the Environment, said the way tourists travel determines a large proportion of the carbon footprint. Flying is a high-carbon mode of traveling.
