resenting a 48% response rate. (For a list of the 25 respon-

Airport Authorities

sented large airport authori-
ties that manage more than
one airport. For the purposes
of data analysis, we have

as one airport, although their
responses may represent sus-
tainability practices at more
than one airport.
