Mexico to Produce Unleaded Gasoline

Mexico will begin producing unleaded gasoline in an attempt to reduce dangerous amounts of pollution produced by Mexico City’s 3 million motor vehicles, the Ecology Ministry announced Monday.

The state-owned oil monopoly, Petroleos Mexicanos, introduced a lower-lead gasoline last September, which officials have said reduced lead levels in the air. But ecologists say that new gasoline has increased the amount of ozone pollutants in the atmosphere.

Ecologists say that 80% of the heavy pollution that afflicts this capital is caused by vehicle emissions.
