Global climate changes have significant impact on cities around the world, although the exact threats can vary significantly depending on the geographic region. Kyiv is a capital city with large population and vast area, which faces different challenges imposed by changing climate. The analysis of climate models demonstrates vulnerability of Kyiv urban infrastructure to heat waves, urban heat island, increasing precipitations and negative weather phenomena. The research was conducted for the Osokorky district of Kyiv to determine its problem points and evaluate the resilience of infrastructure. The results of analysis show that in spite of novelty of the district it lacks sustainability components, has poorly developed green and blue infrastructure, as well as inefficient road network. All these factors combined with dense construction create favorable conditions for the thermal pressure at local population and other biotic components of the district. The suggested approach to the adaptation of Osokorky district to climate changes is through the implementation of nature-based solutions with the aim to expand green infrastructure and increase the volume of ecosystem services provided by urban plants. The green roofs design was developed for 15 sites around the district, based on their location and favorable technical conditions. The economic costs of the project were estimated and the payback period based on the value of ecosystem services provided was defined. In order to strengthen the resilience of the district a complex of additional organizational measures is necessary to support the progress towards safe urban environment.
