EPA says pollution from trains underrated

| Tuesday, August 15, 2006

While there’s been a lot of attention given to how much pollution heavy trucks put into the air, there hasn’t much discussion about trains – until now.

The Washington Post reported that government scientists have been seriously underestimating the amount of soot and nitrogen oxide generated by locomotives.

According to the Post, the scientists have long used faulty estimates of how much diesel fuel locomotives use, which has been causing them to underestimate emissions.

And although heavy trucks presently pollute more than trains, the paper says new emission-control standards for trucks will change that, and that by 2030, locomotives in their current state could emit nearly twice as much soot as trucks.
