Often remains unknown how to apply and measure sustainable development into reality.0ne way to measure the sustainable development of cities, is achieved by measuring the eco-efficiency. Ecoefficiency, two-dimensional indicator of sustainable development, is one of the ways in which sustainable development can be implemented at all levels. Assess the current eco-efficiency of the city means to answer the question: how effectively we use inputs (resources) in relation to the desired output (value to society) and what are the side effects (environmental impacts)? The paper describes three possible approaches to measuring the eco-efficiency of the city, and it means; sets of individual indicators for each of the three ecoefficiency (use of resources, pollution and social values), a set of indicators of eco-efficiency and ecoefficiency index. Application of the concept of eco-efficiency in urban areas means creating greater value for citizens, while reducing the use of resources and reduce waste and pollution.
