Improving quality of life still remains the main goal of strategic documents and is promoted by leaders on the global, national, regional, and local levels. Moreover, this ambitious challenge should be consistent with the principles of sustainable development, including the social, economic, and environmental aspects. The ISO 37120 indicators within the World Council on City Data (WCCD) database may be used to monitor the urban performance over time. However, the interpretation of the results is not always easy and sometimes requires a complex analysis. The aim of this paper was to investigate the possibility of illustrating in a transparent way the urban quality of life using the utility method. This study also presents that this method may facilitate making data-driven decisions on urban management, planning and investment. Thus, it may be useful for decision makers and help cities and communities of all sizes to become more sustainable, safe and resilient, prosperous, inclusive, and smart. The analysis has been carried out using the examples of selected European cities: Amsterdam, Gdynia, London, and Zagreb. The hypothesis reads as follows: it is possible to use the total and partial utility method in order to assess the level of urban quality of life with regard to the three dimensions of sustainable development in order to monitor progress and results and prioritize and implement the changes within urban policy. Research results indicate that there are significant differences between the compared cities within the economic, social, and ecological aspects. This analysis may constitute an introduction to the development of more complex models in the future.

Humanity is exceeding planetary boundaries, and it seems that it is unlikely to meet internationally agreed sustainable development goals. Current trends and challenges in the domain of urban sustainability assessment have proven that measuring and interpreting results regarding quality of life requires a complex analysis. The aim of this paper is to investigate the possibility of comparing, in a transparent way, urban quality of life using sustainable development indicators based on the ISO 37120 standard, taking as case studies seven selected cities: Amsterdam, Buenos Aires, Dubai, Gdynia, London, Los Angeles and Zagreb. The hypothesis reads as follows: the ISO 37120 indicators, converted into partial and total utility value, then grouped within sustainable development dimensions (environmental, economic and social) may be used to measure the level of urban quality of life. Research results indicate that there are some significant and interesting differences between the compared cities within the environmental, economic and social pillars. The analysis, conducted with the use of utility method, may facilitate taking the right decisions on urban management, planning and investment. Thus, this tool may be useful for decision makers and help cities and communities of all sizes to become more safe, resilient, prosperous, inclusive, smart and sustainable.
