Abstract: This paper criticizes the progress of the Brazilian government in preventing greenhouse gas emissions originating in urban areas. In 2009, Brazil approved its “National Policy on Climate Change”, complementing the 2008s National Plan on Climate Change (NPCC). In these documents, the federal government established measures to be undertaken in order to reduce greenhouse gases emissions, focusing on deforestation. However, the federal government should have regulated urban emissions, since the present Brazilian urbanization context, with big metropolises and the gradual migration of the population to the suburbs, represents a burden on climate change. With this new reality, transport and electricity use tend to grow, with the consequent increase in emissions. On the other hand, the municipalities are responsible for most city planning and transportation policies in Brazil. Pressed by their daily needs, they show little concern towards climate change and do not include the regulation of major sources of emissions among their priorities. Consequently, the municipalities are inefficient in preventing climate change. There are two main explanations for that: they do not have the know-how to prevent emissions; and they do not share this political agenda, since the impact of climate change is seldom acknowledged in the city where the emissions occur. Therefore, the central government has a role to play in regulating urban emissions. The study concludes that the National Plan and the National Policy, being federal documents, should have addressed urban emissions throughout the nation. Ultimately, they should be revised to guide city planners into planning greener cities. In order to succeed in this task, this legislation should not only require the reduction of emissions, but it should also indicate to the municipalities how they might achieve the reduction.

Municipalities in developing countries can contribute to mitigating climate change and thereby benefit from reductions in the emissions of conventional pollutants and traffic jams or from improvements in waste management systems, amongst other local benefits. These benefits result from measures taken to reduce greenhouse gases emissions (or carbon sequestration) by two means: either measures taken to mitigate greenhouse gases emissions themselves and/or from the income obtained in the international carbon market. The evaluation of the current status of emissions and the potential for mitigation measures are based on various planning techniques, such as inventories and scenario building, as suggested in the paper. A brief report of the experience in making an inventory from secondary data and building up scenarios that has been undertaken in Rio de Janeiro, Brazil, is presented as a case study. Mitigation measures that are beneficial to the quality of city environments and suited to municipal administrations are also presented. [Copyright &y& Elsevier]
