What was once a dream, is becoming a reality in the city of São Paolo, in south-eastern Brazil.

Being the largest city in Latin America, and one of the most economically developed in the world, the city is also a world reference in terms of air pollution. According to figures the WHO Word Index, the city of São Paolo has air pollution levels three times higher than is acceptable.

On some days of the year, this even causes the suspension of school activities and the city of São Paolo began to seek solutions for the immediate reduction of pollution levels to improve the lives of its citizens and most importantly its young infants.

One of these practices aimed at improving air quality was developed with Brazilian technology, the result of a partnership project between the UN Development Programme (UNDP), the Ministry of Mines and Energy of Brazil, the Brazilian Cooperation Agency and EMTU/SP (Empresa Metropolitana de Transportes Urbanos de São Paulo).

The buses will circulate on the São Mateus-Jabaquara route (metropolitan region of São Paulo).

Since June 2015, three trial vehicles have been running on this line. According to officials, the propulsion technology is completely free of greenhouse gas emissions.

Instead of CO2, these new vehicles emit water vapour. Circulation begins daily at 5:20am and 5:40am on line 287-Piraporinha, a popular route with the users of public transport in the region.

Besides contributing to mitigate global climate change, the new buses also help boost the use of clean technologies for transport in the country.

“The development of hydrogen-powered vehicle technology in national  is still a process restricted to a select group of countries. That leaves Brazil in a world leading position in the area”, says Rose Diegues who is responsible for the UN’s Sustainable Development program.

Measures like the one implemented by the city of São Paolo confirm the global trend in sustainability at the service of the environment and a better quality of life.

The use of fossil fuels and the pollution of the planet are increasingly detached from reality.
