The relationship between political orientation and sustainable consumption has been a focal point of research in environmental psychology, sociology, and behavioral studies. This body of work highlights how political beliefs significantly shape attitudes and behaviors toward environmental sustainability. Studies consistently demonstrate that individuals with left-leaning or liberal political orientations are more likely to engage in pro-environmental behaviors, such as sustainable consumption, due to stronger environmental concerns and a greater acceptance of climate science. In contrast, those with right-leaning or conservative orientations often exhibit skepticism toward environmental issues, influenced by system-justification beliefs, individualism, and resistance to regulatory interventions. Thus, environmental issues, particularly climate change, are politized. Political polarization has led to divergent perceptions of climate risks, with liberals more likely to adopt sustainable practices and conservatives more resistant to such behaviors. Additionally, materialistic values and economic priorities often conflict with sustainable consumption, particularly among politically conservative groups. Overall, the literature underscores the critical role of political orientation in shaping environmental attitudes and behaviors, offering insights for policymakers and advocates aiming to foster broader engagement in sustainable consumption. This paper aims to validate political orientation and attitude towards environmental issues, mainly on sustainable consumption. The research forms the most influential policy combination of Progressivism and Conservatism based on three fuzzy models, Mamdani, Sugeno, and ANFIS, to reach sustainable consumption ideas that is supported by the consumers. Note that a high level of Progressivism has the most influential impact on sustainable consumption.
