Airports

California must operate and maintain an effective and efficient transportation infrastructure while ensuring that the health of communities and the planet are not compromised. By assessing transportation projects using a life-cycle perspective, all relevant emission sources and activities from the construction, operation, maintenance, and end-of-life phases can be analyzed and mitigated. This report presents a framework to assess the life-cycle human health and climate change impacts from six types of transportation projects: (1) Roadways; (2) Marine ports; (3) Logistical distribution...

Airports are complex social, technical, and environmental systems. Understanding their complexity is fundamental for advancing transformative climate adaptation policy. For airports to adapt, climate science must be incorporated not only into standards of specific equipment and facilities, but also into the air traffic network and its interconnected infrastructure systems (e.g., road access, ground-based communications, navigation, and surveillance systems). In addition, airport adaptation requires a shift in the way policy is designed, reinforced, and updated, which in turn relies on an...

At a national level it is common to express the amount of air travel in terms of the number of revenue passenger miles flown or the number of enplaned passengers. This provides a way to resolve the difficulty of how to aggregate measures of air travel in many different markets of many different distances. However, information about the distribution of trip lengths is lost in the process. This information is of interest for a number of reasons. The type of aircraft that is most appropriate for different markets depends on the distances involved. The length of the trip is also likely to...
