Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

  A‐1    Appendix A: Glossary of Terms   100% renewable. A condition in which renewable resources (such as wind, solar, geothermal, hydro  power, and biomass) supply all airport electricity.   Airport Carbon and Emissions Reporting Tool (ACERT). A method used by an airport operator to  calculate their airport’s greenhouse gas (GHG) emissions by source.  Airport Cooperative Research Program of the Transportation Research Board. An industry‐driven  research program that examines problems faced by airport operators and develops near‐term, practical  solutions.  Aviation Environmental Design Tool. Tool that models dynamic aircraft performance in space and time,  demonstrating interdependencies between aircraft‐related fuel burn, emissions, and noise.  Carbon neutral. A condition in which airport‐controlled CO2 sources and sinks are zero.   Carbon negative. A condition in which airport‐controlled CO2 sources and sinks are negative.   Climate neutral. A condition in which airport‐controlled emissions do not contribute to climate change.  (Though similar to carbon neutral, this condition implies all GHGs are included).   Climate positive. A condition in which an airport goes beyond achieving net‐zero emissions to removing  additional emissions from the atmosphere.  Deep decarbonization. A condition in which airport‐controlled emissions are dramatically lowered.  Typically, this refers to an 80% reduction in GHGs relative to 1990 levels or 2005 levels.   Intergovernmental Panel on Climate Change (IPCC). Intergovernmental body of the United Nations  (UN), tasked with researching the natural, political, and economic impacts and risks of climate change,  and with developing feasible response options.  Low emission. A condition in which airport‐controlled emissions are low but positive. No numeric  threshold has been defined for meeting this condition.   Net‐carbon negative. This condition is the same as climate positive.   Net zero. A condition in which airport‐controlled emissions are zero with use of offsets. This condition is  similar to carbon neutral, but it includes all GHGs.   Roadmap. A methodical plan or strategy designed to achieve a particular goal.  Zero carbon. This condition is the same as carbon neutral.   Zero carbon footprint. This condition is the same as carbon neutral.   Zero carbon growth. A condition in which airport‐controlled CO2 emissions do not grow larger each year.   Zero emissions. A condition in which airport‐controlled emissions are zero without the use of offsets.  This condition can only be met when all end uses are electrified or use zero or negative emissions  synthetic fuels.

Airports worldwide are setting aggressive zero- or low-emissions targets. To meet these targets, airports are deploying new strategies, adopting innovative financing mechanisms, and harnessing the collective influence of voluntary emissions and reporting programs. In tandem, new and affordable zero- or low-emissions technologies are rapidly becoming available at airports.

The TRB Airport Cooperative Research Program's pre-publicaton draft of ACRP Research Report 220: Guidebook for Developing a Zero- or Low-Emissions Roadmap at Airports covers all steps of roadmap development, from start to finish, using conceptual diagrams, examples, best practices, and links to external tools and resources. While the main focus of this Guidebook is airport‐controlled greenhouse gas (GHG) emissions, it provides discussion about airport‐influenced emissions from airlines, concessionaires, and passengers.

Whereas other guidebooks and reference material provide airports with information on emissions mitigation and management (for example, the Federal Aviation Administration’s Airport Carbon Emissions Reduction, ACRP Report 11: Guidebook on Preparing Airport Greenhouse Gas Emissions Inventories, and the Airport Council International’s Guidance Manual: Airport Greenhouse Gas Emissions Management), this Guidebook articulates steps for creating an airport‐specific emissions roadmap.
