The city is like an organism, and the swift movement of people and goods is the oxygen that sustains its well-being. When this circulation is inhibited, it significantly compromises the quality of urban life. For example, private cars account for less than one-third of trips in cities worldwide, but are responsible for 73% of urban air pollutants. Per capita, private cars generate three times more greenhouse gas emissions than public transport systems like buses. In the last year, the transport sector accounted for 46.9% of Brazil’s energy-related carbon dioxide emissions.
Rapid global urbanization comes with the potential to accelerate current climate change trends, and transport emissions may even triple by 2050. In addition to the severe consequences for the global climate, rising greenhouse gas emissions from motor vehicles also have a direct impact on human health. Air pollution contributed to 3.7 million deaths worldwide in 2012. It’s also estimated that urban air pollution contributes to 7,000 premature deaths per year in metropolitan São Paulo and reduces life expectancy by 1.5 years on average.
