摘要

This paper examines the current and future air quality impacts that occur as a result of the development of NorthrnAmerican trade and transportation corridors, and explores strategies to mitigate these impacts. The analysis focusesrnon five specific bi-national corridor segments: Vancouver-Seattle, Winnipeg-Fargo, Toronto-Detroit, San Antonio-rnMonterrey and Tucson-Hermosillo. For each segment, commodity flow and ground freight traffic volumes (truckrnand rail) are used to estimate current air pollution emissions associated with cross-border trade. Cross-border freightrnis found to be responsible for 3% to 11% of all mobile source NOx emissions and 5% to 16% of all mobile sourcernPM-10 emissions in the corridor regions. Trade forecasts to 2020 are used to estimate future trade-related emissions.rnCO2 emissions from cross-border trade will increase by 2.4 to 4 times over their current levels in the five corridors.rnDue to the expected improvement in criteria pollutant emission controls for trucks and locomotives, total traderelatedrnemissions of NOx and PM-10 in 2020 will decline or remain constant compared to current levels, despiterntrade volumes that grow by two to four times. The paper also discusses the impact of six emission mitigationrnstrategies: alternative fuels for heavy trucks, reducing border delay, low sulfur diesel and use of advanced emissionrncontrols for trucks in Mexico, reducing empty freight mileage, expanded use of longer combination vehicles, andrnuse of advanced emission controls for locomotives.
