Green areas must be planned along with other city policies because they are important spaces that maintain the quality of the urban environment. The pattern of urbanization, especially with cities in the developing world, has negatively influenced green areas and, as a consequence, reduced the environmental benefits provided by them. São Paulo is one of the world’s biggest cities in terms of territorial occupation and population, but its unplanned development has led to serious impacts on its green areas. As a result, this has caused many worsening social and environmental problems, such as flooding and bad air quality. Considering that information is a central factor in the planning process of these areas and that São Paulo has an environmental quality report, the Global Environmental Outlook (GEO) of São Paulo, the purpose of this paper is to analyze the potential of this report to support the planning process of São Paulo’s green area system. An indicator framework was described to help the planning of these areas. The indicators presented in Geo São Paulo were selected to create a framework for the policy support. The indicators were selected by their relationship with the green areas directives shown in the city master plan. The indicators were also analyzed by technical and
policy relevance criteria.
