In the Level 4 'Transformation' of Airport Carbon Accreditation, airports need to align their carbon management targets with global climate targets and transform their operations with absolute emission reductions while strengthening stakeholder engagement.
How to achieve?
More information
To reach Level 4, an airport must set an absolute emission reduction target (ie, an airport operator target scope) that includes, as a minimum, all Scope 1 and Scope 2 emissions. If an airport chooses to do so, it can include one or more of the sources of Scope 3 emissions in its target and thus partially or completely cover the airport as a system (ie a target scope with third parties).
The Implementation Handbook details the requirements for the carbon footprint, the definition of targets and trajectories, and stakeholder partnership.
