Energy Transitions in Cities: A Comparative Analysis of Policies and Strategies in Hong Kong, London, and Melbourne

This paper reports a comparative analysis of energy transition policies in Hong Kong, London, and Melbourne, highlighting their approaches to achieving carbon neutrality. Utilizing a qualitative research approach, the study combines desktop research and policy analysis to examine secondary data from academic literature and policy reports. A structured policy analysis was developed to compare the strategies of each city, focusing on legislative tools, regulatory mechanisms, and decarbonization goals. The findings reveal that, while all three cities aim to reduce greenhouse gas emissions through energy transition policies, they adopt different strategies shaped by their socio-economic contexts. Hong Kong emphasizes regulatory measures like the Buildings Energy Efficiency Ordinance, London uses market-based instruments such as carbon pricing, and Melbourne prioritizes community engagement and renewable energy integration. Despite progress, challenges remain, including compliance with standards, funding, and public awareness. Recommendations include developing benchmarking strategies, fostering public–private partnerships, and investing in education. This analysis provides actionable insights for future policy development, emphasizing adaptability and innovation in combating climate change and fostering sustainable urban environments.
