Improving air quality
Fuel combustion generates not only CO2 emissions but other local air pollutants as well, including mono-nitrogen oxides (NOx), sulfur dioxide (SO2) and particulate matter (PM10). Although their spatial impact is limited, these local air pollutants are a proven hazard to the health and well-being of both humans and the environment. Our fleet modernization efforts, which include replacing older aircraft and vehicles with newer, more modern equipment, help lower air pollutant levels.
A significant share of our scope 1 greenhouse gas emissions is generated by our air network operations in our EXPRESS division. To help shrink this footprint, we are committed to investment in newer, more efficient aircraft. Our efforts to modernize our dedicated air fleet continued in 2013. As a result, we were able to increase the number of jet aircraft that meet the highest emission standard (CAEP/6) by approximately 13%. The emission standards are defined by the Committee on Aviation Environmental Protection (CAEP), part of the International Civil Aviation Organization (ICAO).
