Carbon neutrality is when the net carbon dioxide
emissions over an entire year is zero. Achieving carbon
neutrality for an airport is in almost all cases impossible
without external help. For this reason, airports, among
many other industries, look to carbon offsetting as the
final part of the process. Carbon offsetting is providing
funds or resources to other projects that reduce
carbon dioxide so as to make up for the emissions
that one is not able to eliminate. Airport Carbon
Accreditation has been designed to give participant
airports significant flexibility within specific parameters
in deciding how they should offset their emissions in
order to achieve carbon neutrality.
