Air pollution is one of Ostrava’s biggest environmental problems. The key objective of CLAIRO project was to decrease gradually and systematically air pollution through comprehensive planning and planting of municipal greenery with proved positive impact to air quality. Building on accurate measurement, robust data, new scientific solutions and involvement of experts from different sectors, a new methodology was tested facilitating the design of city greenery in the most efficient structure and composition taking into account natural conditions e.g. airflow. The project tested new solutions in the field of plants with evidence-based impact to air quality and shared these with other cities the cross-border Silesian conurbation. The resistance of plants was strengthened through new phytohormones and biostimulants to maximize the effect of the vegetation while a new generation of sensors allowed fast short-term measurements of both organic and inorganic substances.

During its implementation, the UIA project has capitalised on its experience so that it can be shared with peers. The outputs displayed on this page are the result of this process.
