Studies sponsored by the World Health Organisation suggest that more than 15,000 people in Italy die every year from car-exhaust fumes. A recent poll also revealed that more than 66.8 percent of Italians believe that the government and the private sector are disregarding the needs of the environment. Five regional committees signed a formal agreement outlining plans to improve air quality in northern Italy. The regions of Piedmont, Lombardy, Veneto, and Emilia Romagna, as well as the autonomous Trento, undersigned new policies, including financial incentives to encourage individuals and businesses to use vehicles powered by environmentally friendly fuels like hydrogen.
