Walking the Circularity Talk: Evidence from Case studies and Research Professor Ahmed Khalifa

College of Business and Economics Qatar University

Abstract 1

Our research explores pathways to a circular economy for sustainable development, focusing on Qatar and broader global contexts. The QNV2030's goal of sustainable economic development necessitates entrepreneurial and economic diversification, fostering a circular economy through diversification and leveraging opportunities in the energy transition and waste management. Achieving net-zero emissions by 2050 requires tackling both energy and non-energy related GHG emissions via CE transition. Our systematic review identifies technology, finance, ecosystem factors, and behavioral changes as key accelerators. Additionally, our comparative analysis across nations reveals that while command-and-control regulations and market-based mechanisms (carbon taxes, emissions trading) offer varying levels of success in promoting CE principles, information-disclosure strategies are essential for consumer empowerment. From public policy prospective, our studies demonstrate the significant impact of carbon pricing policies, particularly emission trading systems, in reducing carbon emissions globally. Additionally, allocating the carbon permits requires specific scientific approach to guarantee efficacy and the transparency across the economic agents
