In a groundbreaking study published in the journal Mathematics, researchers have unveiled a comprehensive analysis of the factors influencing carbon dioxide (CO2) emissions in Romania, utilizing advanced methodologies to explore the potential of circular economy (CE) strategies. Led by Camelia Delcea from the Department of Economic Informatics and Cybernetics at Bucharest University of Economic Studies, the research combines fuzzy multi-criteria decision-making (MCDM) methods with the Autoregressive Distributed Lag (ARDL) model to prioritize effective policies for reducing emissions.
The study spans over three decades, examining emissions data from 1990 to 2023, and highlights the critical role that renewable energy production plays in mitigating CO2 emissions. “Our findings show a clear negative relationship between renewable energy production and CO2 emissions in the long term,” Delcea noted. This insight is particularly relevant as Romania seeks to transition from a linear economic model to a more sustainable circular economy framework, which emphasizes efficient resource use and waste minimization.
The research identifies five key factors influencing emissions: CO2 emissions per capita, patent applications, gross domestic product (GDP), the share of energy production from renewables, and urbanization. Interestingly, while GDP growth is often associated with increased emissions, the study reveals that in Romania, economic growth does not significantly drive CO2 levels in the long run. This decoupling suggests that improvements in energy efficiency and the shift towards less carbon-intensive industries may be taking effect.
Delcea’s study employs innovative fuzzy MCDM methods—Fuzzy Electre, Topsis, DEMATEL, and Vikor—to rank six policies aimed at reducing emissions. The research underscores the importance of prioritizing these strategies, especially as Romania grapples with the dual challenges of urbanization and environmental sustainability. “By focusing on resource efficiency and innovation, we can significantly contribute to sustainability and emission reduction,” Delcea emphasized.
The implications for the energy sector are profound. As Romania invests in renewable energy and circular economy initiatives, the research serves as a roadmap for policymakers, guiding them to implement strategies that not only reduce emissions but also stimulate economic growth. This shift is crucial for the energy sector, which must adapt to new regulations and market demands that prioritize sustainability.
The study also points to the potential trade-offs between urbanization and environmental health. As cities expand, the demand for energy rises, leading to increased emissions. Delcea warns that current economic policies may not adequately address these challenges, urging a reevaluation of urban planning and energy policies. “Policymakers need to balance economic growth driven by urbanization with the environmental goal of reducing CO2 emissions,” she stated.
With the urgency of climate change pressing upon nations worldwide, the findings from this study not only contribute to academic discourse but also have real-world applications that can influence Romania’s energy policies for years to come. The integration of fuzzy MCDM methods with econometric modeling offers a unique perspective on how to effectively implement circular economy strategies, paving the way for a more sustainable future.
