Special Issue Information

Dear Colleagues,

According to the World Bank, about 60% of the world's population now lives in cities, and cities contribute 80% of the world's GDP. Urbanisation generates daily challenges due to its speed of expansion, making the ability to create liveable, viable, sustainable, and inclusive spaces more important. But it should not be forgotten that cities are major centres of consumption, demanding materials and energy.

Therefore, their role in the fight against climate change is key, and it is a challenge for the future to ensure that their development model turns them into ecological, resilient, and inclusive enclaves. To this end, the design of energy management policies is a key element, considering the social, economic, energy, and environmental impacts, among others.

This Special Issue contributes to generating knowledge in the field of energy management and policy planning for more sustainable, resilient, and inclusive cities. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Urban energy consumption;
  • Urban forestry;
  • Urban environments;
  • Sustainable transportation;
  • Waste planning;
  • Urban ecological governance;
  • Land resources and dematerialisation;
  • Social impacts and sustainability;
  • Energy poverty and inequality in urban spaces.

I look forward to receiving your contributions.

Assessing Energy Consumption and Treatment Efficiency Correlation: The Case of the Metamorphosis Wastewater Treatment Plant in Attica, Greece
by Nikolaos Tsalas, Spyridon K. Golfinopoulos and Stylianos Samios
Urban Sci. 2025, 9(6), 201; https://doi.org/10.3390/urbansci9060201 - 2 Jun 2025

Wastewater treatment plants (WWTPs) are crucial for environmental protection and public health; however, they are among the most energy-intensive facilities in the water sector. This study examines the correlation between energy consumption and treatment efficiency at the Metamorphosis WWTP (MWWTP) in Attica, Greece, during the years 2022 and 2023. By analyzing influent and effluent characteristics, energy consumption patterns, and the removal efficiencies of key pollutants—Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD5), and Suspended Solids (SS)—this research provides valuable insights into optimizing wastewater treatment operations. The findings reveal that, despite seasonal variations and fluctuations in influent composition, the facility consistently achieved high pollutant removal rates while maintaining stable energy consumption. The influent BOD5 increased from 992.8 mg L−1 in 2022 to 1122.3 mg L−1 in 2023. COD rose from 1925.4 mg L−1 to 2594.4 mg L−1, SS from 1280.8 mg L−1 to 1421.2 mg L−1, and total phosphorus from 14.2 mg L−1 to 17.0 mg L−1. Effluent concentrations remained consistently low, with BOD5 at 6.1 mg L−1 in 2022 and 4.7 mg L−1 in 2023; COD at 23.8 mg L−1 and 25.2 mg L−1, respectively; total nitrogen at 20.2 mg L−1 and 16.7 mg L−1; total phosphorus at 2.4 mg L−1 and 2.6 mg L−1; and SS at 2.4 mg L−1 and 3.5 mg L−1. These results indicate removal efficiencies exceeding 90%. Energy consumption remained stable, recorded at 13,044.9 kWh (0.593 kWh m−3 influent) in 2022 and 13,126.1 kWh (0.598 kWh m−3 influent) in 2023. These results highlight the importance of integrating energy-efficient strategies and renewable energy solutions to enhance wastewater treatment plant (WWTP) sustainability. This study contributes to ongoing efforts to improve energy optimization in wastewater treatment, supporting global initiatives for carbon footprint reduction and advancing the principles of a circular economy.

The role of carbon emissions in the worsening of global warming and other climate change implications has been well recognised. This study empirically investigates the effect of economic growth, urbanisation, and energy consumption on carbon emissions using panel cointegration tests and pooled mean group autoregressive distributed lag (PMG-ARDL) techniques. The research is based on panel data from Western Balkan countries spanning 2001 to 2022. Urbanisation is incorporated into the model to determine its significance in the dynamic relationship among economic growth, energy consumption, and carbon emissions. The inclusion of urbanisation in the Western Balkans context is particularly novel because of its acceleration in this region. The findings suggest that energy consumption, economic growth, and urbanisation significantly affect environmental quality in the long run. In contrast, it has been demonstrated that only economic growth significantly impacts the environment in the short run. Subsequent investigations have revealed that environmental distortion is a long-term consequence of energy consumption, urbanisation, and economic expansion in the examined nations. These countries must prioritise enhancing energy efficiency, urban planning, and pollution mitigation measures while ensuring that economic growth remains unhindered. Full article
