Pollutant Emissions 45% open

What data is expected?

Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:

• Particulate matter (PM) Levels
• Sulphur oxides (SOx)
• Nitrogen oxides (NOx)
• Volatile organic compounds (VOCs)
• Carbon monoxide (CO)
• Updated on at least once a week.
• Measured either at a national level by regions or at leasts in 3 big cities.

Details

The Brazilian Federal Institute for Geography and Statistics - IBGE produced time series between 1992 and 2009/2010 referring to the air pollution in metropolitan areas. However, these data is not being updated anymore. The data does only cover some Brazilian cities. Additionally to this the Instituto Nacional de Pesquisas Espaciais publishes green house effects based on changes to land coverage in Amazon region: http://inpe-em.ccst.inpe.br/downloads.html. Apart from this data on air quality falls under the authority of the state government. It is provided for the state of São Paulo here: http://www.cetesb.sp.gov.br/ar/qualidade-do-ar/31-publicacoes-e-relatorios The evaluation was made for the air quality data of São Paulo. No (daily) microdata is provided but the report shows a lot of details on the data collection and data for each point of measurement although aggregated over the year.

A national level report with data for the following metropolitan regions.

• Distrito Federal
• Vitória
• Belo Horizonte
• Curitiba
• Rio de Janeiro
• Salvador
• Porto Alegre
• São Paulo
• Santos
• Campinas

It contais measurements for PM, SOx, NOx and CO, but not VOCs. Report produced in 2013.

Some state-level environment agencies do have more up to date reports, for instance

Distrito Federal: http://www.ibram.df.gov.br/informacoes/meio-ambiente/qualidade-do-ar.html

None of these do measure Volatile organic compounds (VOCs), however.

Air Quality: http://meioambiente.cptec.inpe.br/index.php?lang=pt

• Carbon monoxide (CO)
• Ozone (O3)
• Nitrogen oxides (NOx)
• Volatile organic compounds (VOCs)
• Particulate matter (PM) Levels
