As global carbon reduction gains momentum, the tourism industry works to lower emissions across all tour elements. From choosing meeting points and transportation methods, to incorporating environmental education and selecting eco-friendly restaurants, professional institutions now calculate carbon footprints using international standards. Unavoidable emissions are offset through purchasing Verified Carbon Standard (VCS) certified carbon credits, achieving genuine low-carbon tourism.Pinglin, renowned for producing Paochung tea, pioneered Taiwan's low-carbon tourism movement.
