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.
