China’s ski tourism industry has grown tremendously in the past few years, leading to an increasing amount of tourism-related carbon emissions with negative environmental impacts. Although the government and other market participants are trying to solve the problem from both legislative and technological perspectives, encouraging tourists to engage in low-carbon behavior may play a more important role. This study aims to explore how tourism involvement influences ski tourists’ low-carbon behavior. A sampling survey was conducted to collect 422 valid responses from two ski resorts (indoor and outdoor). Findings from structural equation modeling revealed a significant positive impact of tourism involvement on both low-carbon tourism behavior and low-carbon daily behavior, and this impact can be serially mediated by place attachment and environmental responsibility. In addition, we confirmed that the impact of ski tourism involvement on place attachment is more significant for outdoor ski resorts compared with indoor ones. This study expands the categories of destinations for research on ski tourism and low-carbon behavior. It provides implications for encouraging visitor pro-environmental behavior while corroborating the social value of ski tourism in addressing environmental issues. It also offers insights for government low-carbon campaigns, business management practices, and individuals with actionable attitudes. However, it is worth noting that this study was conducted in a single latitude region and did not conduct a comparative analysis with different locations across latitudes. Future research could investigate skiers in cities of different latitudes to gain a more comprehensive understanding.
