Greenpeace Brazil opens the Mobility Week with an impressive protest to demand non-polluting buses in São Paulo. Activists bring Death itself to São Paulo City Council, along with a tombstone with the name of the city on it and 11 victims - the average number of daily casualties due to diseases caused or intensified by the diesel engines combustion in public buses. The president of the City Council, Milton Leite, is trying to approve a bill which would keep diesel engines in buses for at least other 10 years. The mayor João Doria has the power to demand that the bus companies use cleaner and greener vehicles in the city's public transportation bidding.
