ParCur Project – “Study of the emissions of particulate matter and black carbon and related impact on air quality in Curitiba and Metropolitan Region”

The city of Curitiba in the state of Paraná, in Brazil, has a long tradition of sustainable urban planning and innovative urban concepts. The Sweden/Brazil cooperation project ParCur aims at taking into account the air quality impact caused by urban expansion and densification.

Curitiba gained worldwide prominence for its efficient practices in urban planning and public transport. Engaged in project sustainability and social responsibility, the city now draws goals aimed at improving the population's quality of life.

Although urban densification along mass transport axes is a tested concept in Curitiba, it requires that air quality impacts from transport vehicle exhausts (with effects on human health) are taken into consideration in the planning process. A sustainable urban development also requires other pollution sources affecting Curitiba air quality to be assessed.

The Bilateral Cooperation Project ParCur was born under the framework of the “MoU between the Ministry of the Environment of the Kingdom of Sweden and the Ministry of the Environment of the Federative Republic of Brazil on cooperation in the fields of environmental protection, climate change and sustainable development” (signed in Nov. 20, 2013), the “MoU between Brazilian and Swedish Institutions to promote sustainable urban development in Curitiba” (signed in Nov. 12, 2013), and the project “Smart city concepts in Curitiba” (VINNOVA call 2014-01762).

Project goals

The general goal is to enhance the benefits of on-going sustainable development of the urban infrastructure in Curitiba by assessing and quantifying the air quality improvements in the city and its metropolitan region, as a necessary step to attain improved life quality standards and a healthier population.

In order to accomplish this overarching goal the following general objectives were envisioned:

  • to cooperate on methodologies for the quantification of emissions of small particles (PM2.5 and Black Carbon - BC) and their impact on air pollution levels in Curitiba´s metropolitan region;
  • to support and complement the on-going project “Smart city concepts in Curitiba” with air quality impact assessments, following the introduction of new technologies for mass transport corridors.

SMHI role

General coordination of the project. Development of a high spatiotemporal resolution emission inventory for PM and BC for the metropolitan region of Curitiba. Implementation of the web-based air quality management system Airviro. Capacitation of the Brazilian partners in the use of Airviro, namely for monitoring assessment, emission inventory, and dispersion modelling.
