“…As a social psychological theory, the TPB has been used as the basic theory to analyze the formation process of various human pro-environmental behaviors [17,18], such as energy saving [19,20], recycling [21,22], green purchasing [23,24], and so on. In particular, it is also used in the field of research on tourists' pro-environmental behaviors related to waste management, for example, tourists' intention to reduce plastic use after naturebased experiences (a humpback whale encounter) from Australia and Tonga [25], tourists' intention about plastic waste reduction on beaches in Saudi Arabia [26], tourists' waste reduction intention at general US hotels [27], tourists' intention to reduce waste generation in mountainous tourism areas in China [1,13,28], and tourists' waste classification intention in Chinese rural destinations [29]. A common feature of past studies was that scholars extended TPB in different forms according to different research backgrounds, purposes, and contents so as to improve the predictive power of the original TPB model on proenvironment intentions and behaviors.…”
