7 levels of accreditation

Level 2: Reduction

At Level 2 ‘Reduction’ of Airport Carbon Accreditation, airports are required to set up their carbon management and progress towards a reduced carbon footprint.

How to achieve it?

To achieve this level of accreditation, an airport has to:

  • Fulfill all the requirements of ‘Mapping’
  • Provide evidence of effective carbon management procedures including target setting
  • Show that a reduction in the carbon footprint has occurred by comparing its latest carbon footprint to the emissions of the previous years

More information

Once an airport has measured its carbon footprint, it can work towards reducing its carbon emissions. This process is known as carbon management and involves a diverse range of measures, by which an airport should:

  • Have a low carbon/low energy policy
  • Show that a senior committee or body has responsibility for climate change/carbon/energy matters
  • Monitor consumption of fuel and energy
  • Have carbon/energy reduction targets
  • Put in place actions, programmes or control mechanisms to ensure operations minimise emissions
  • Consider emissions impact of investments
  • Undertake awareness training about emissions for staff
  • Have a process of self-assessment and auditing to monitor progress towards improvements
  • Communicate emissions performance to relevant stakeholders


Specific examples of carbon management measures might include:

  • Energy demand reduction – through audit, measurement, management, automated meter reading (AMR), automated monitoring and targeting (AM&T), well set and effective control
  • Clean energy supply – combined heat and power, renewable energy sources (on-site or off-site)
  • Low energy design – standards for refurbishment and new build, compulsory inclusion of carbon reduction studies in all new projects
  • Options for alternative fuel airport vehicles (electric, hybrid, hydrogen, LPG, etc.)
  • Staff communications and engagement plans
  • Equal or preferential appraisal for carbon-reducing investment projects
  • Programme to examine and reduce supply-chain-related emissions
