* Mexico urged to pass strong emissions limits for heavy trucks; 20,000 deaths cited
-- Heavy-duty trucks represent a major part of the problem... That's led the U.S. and Canada to tighten emissions standards for large trucks in recent years. Now three environmental groups are urging Mexico to do the same. They claim these rules could cut emissions of particulate matter and nitrogen oxides from trucks 90 percent... The debate comes in the wake of Mexico's first smog alert in 11 years... As part of a four-day alert earlier this month, the government banned more than one million vehicles from entering Mexico City, as ozone levels rose to twice the acceptable limits... Transportation emissions already cause 20,000 premature deaths in Mexico per year, said Dan Greenbaum, president of the Health Effects Institute... Mexico has already pledged to cut emissions 22 percent from 1990 levels by 2030, as part of its commitment to the Paris climate-change agreement. It has also established a peak year for emissions, 2026... And the government wants a 50-percent cut in "black carbon" emissions—created by burning diesel and other fuels... But the groups claim that the new standard, called NOM-44, is in danger of being weakened by the government because of pressure from the industry. If passed, it would increase average new-truck costs by three percent, ICCT Senior Fellow Kate Blumberg said in a conference call Tuesday...
