The paper critically evaluates the urban climate change adaptation policy and practise in Central Europe using Polish cities as an example. The study focused on local policy documents and a scoring system was elaborated and applied for their analysis with particular attention to ‘green’ adaptation concepts. The link between the time of adoption and the scores received by cities' Strategies and Programmes for Environmental Protection demonstrates innovation flow from science into urban policy. We revealed that many of the proposed measures in Urban Adaptation Plans represent rather mitigation than adaptation implying substantial knowledge gaps in differentiating between them. A portfolio of projects implemented in 2014–2020 within EU funding programmes and Participatory budget was compiled with further classification into ‘green’, ‘grey’, or ‘soft’. More than 80 % of the selected projects in each of the cities were classified as ‘green’, but only one studied city demonstrated an upward trend in the number and cumulative budget of the adaptation projects. The examined Polish cities, similarly to other Central and Eastern European ones, experiencing fast economic growth have featured a profound contraction of green areas over the last decades. Partially it might be compensated by local environmental programmes that promote application of nature-based solutions.
