Tourism CO2 emissions measure and temporal and spatial differences study — A case of Henan Province in China

In recent years, the tourism industry CO₂ emissions measures become a hot topic of academic research. The tourism carbon emissions´ research is relatively mature in foreign scholars, but domestic scholars are lagging far behind, which is largely subject to our imperfect tourism statistical system. This paper discusses the tourism CO₂ emissions measure based on the statistical coverage of China´s tourism, and applied to a relatively well-developed tourism industry in Henan Province, and calculates the CO₂ emissions of Henan Province tourism sector, and last analysis the spatial and temporal differences of the Henan Province. Concluded that Henan Province tourism CO₂ emissions are rapidly increasing, the intensity of tourism CO₂ emissions is gradually declined, the CO₂ emissions´ disparity of three sectors of tourism is gradually narrowing, the tourism CO₂ emissions of city in Henan Province is quietly different, and so on. Lastly we make several recommendations for tourism energy saving that provide a scientific basis for low-tourism´s development of Henan Province.
