The increasing occurrence of extreme events driven by climate change hasa direct impact on cities, where almost 60 percent of the world s population resides.Nature-based solutions (NbS) have become essential climate adaptation and mitigation strategies on public policies. This study aimed to guide the Rio de Janeiro City Hall in development of NbS in the Low Emission Zone (LEZ). Thus, a Guideline for the Deployment of NbS was formulated to support the City Hall instructuring urban renewal actions in the LEZ. An NbS Selection tool was used and adapted to the context of the LEZ, and the success factors of Rio s institutional capacity in implementing NbS were identified, in addition to the presentation of the 15 recommended NbS. Maps depicting priority areas for green infrastructure within the LEZ were also generated based on the Methodological Guide for Green Infrastructure Implementation. Finally, a conceptual project of NbS was created for two avenues located in the LEZ, to illustrate the practical application of the seactions on a local scale, and a hydrological study of the attenuated storm water volume in the sub-basins of these avenues, to evaluate the performance of the proposed solutions. This study seeks to assist the City Hall s decision-making in the implementation of NbS in the LEZ. The integration of NbS in programs and the realization of public-private partnerships are some relevant strategies to be considered by the City, as well as the realization of further research on NbS directed to the LEZ.
