Does Circular Economy Contribute to Smart Cities' Sustainable Development?

Area of Science:

• Environmental Science
• Urban Planning
• Economics

Background:

• Smart cities aim to enhance urban living through technology and sustainable practices.
• Air pollution remains a significant challenge impacting public health and environmental quality in urban areas.
• Circular economy principles offer a framework for resource efficiency and waste reduction, potentially mitigating pollution.

Purpose of the Study:

• To identify key factors influencing the development of smart environments within smart cities.
• To quantify the impact of circular economy, fiscal, and environmental factors on reducing air pollution.
• To assess the effectiveness of various strategies in improving ambient air quality across European states.

Main Methods:

• Analysis of balanced panel data for 28 European states from 2011-2019.
• Application of regression models including Ordinary Least Squares, Fixed Effects, and Random Effects.
• Selection of 11 key indicators impacting air pollution exposure based on literature review.

Main Results:

• The use of renewable energy sources significantly reduces air pollution.
• Investment in public education campaigns on pollution reduction is effective.
• Proper implementation of circular economy models and supportive EU policies are vital for cleaner air.
• Carbon dioxide-generating activities are identified as a major contributor to increased air pollution.

Conclusions:

• A multi-faceted approach combining renewable energy, circular economy, public education, and strategic policies is essential for reducing air pollution.
• Effective environmental policies are critical for achieving sustainable cities and enhancing citizen well-being.
• Continuous monitoring of ambient air quality and adaptation of policies are necessary for long-term environmental improvement.
