Global perspectives on environmental policy innovations: Driving green tourism and consumer behavior in circular economy.

The tourism industry plays a pivotal role in both economic growth and environmental stewardship, making it essential to adopt practices that ensure long-term sustainability. This research aims at relating to the global concern of sustainable management in the tourism industry which is significant in eradicating the effects of environmental degradation as well as promoting economic development. The research problem focuses on exploring sustainable solutions for encouraging green tourism and implementing circular economy concepts. To address this, this study uses the Pythagorean Fuzzy Step-wise Weight Assessment Ratio Analysis (PF-SWARA) and Pythagorean Fuzzy Complex Proportional Assessment (PF-COPRAS) method to assess and rank the appropriate factors and strategies. From literature research and a consultation with the expert's panel, six factors and twenty-four significant factors have been uncovered. The PF-SWARA outcomes reveal that the most important factors are sustainable resource use (A2), ecosystem restoration (A4), and environmental regulations (A5), signifying that they play a critical role in the attainment of environmental sustainability. Subsequently, the PF-COPRAS analysis was conducted for seven strategic solutions to determine the most important strategy for furthering green tourism. Technological innovations promotion (S3) is the most crucial strategic approach for implementing circular economy concept in the tourism industry. While sustainable infrastructures (S5) and promoting green financing and investments (S2) are next key solutions for sustainable development of the tourism sector. The findings help policymakers and industry players to promote sustainable tourism in changing socio-environmental conditions.
