Carbon footprint

Aena calculates its carbon footprint every year, which makes it possible to monitor the progress made to achieve the objectives of the Climate Action Plan and identify the effectiveness of the measures applied.

Within the corporate carbon footprint, Greenhouse Gas (GHG) emissions are grouped into three scopes:

  • Scope 1: Direct emissions from sources or processes and activities controlled by Aena at its facilities. Included in this scope are stationary combustion sources (generator sets, portable generators, boilers, practices of the Fire Fighting Service and auxiliary pumps of the fire water tanks) and airport vehicles (heavy and light fleet).
  • Scope 2: Indirect emissions which are produced by the generating of electricity or thermal energy produced and consumed at airports.
  • Scope 3: Comprised by the remaining indirect emissions from third-party emissions such as those related to the LTO cycle (landing and take-off of aircraft of airlines operating at airports), APUs (Auxiliary power units that supply energy to aircraft when they´re on land), vehicles and machinery that provide Handling and other services (energy consumption by dealers, land access, employee travel, etc.).

The following data shows the evolution of the carbon footprint in CO2 equivalent tons of Aena and London Luton Airport:

  2019 2020
CO2 equiv. ton Aena LLA Aena LLA
Scope 1 22,769 2,966 17,112 2,326
Scope 2 113,861 4,981 26,199 3,418
Scope 3 3,852,793 275,787 1,870,735 107,289

NOTE 1: The data for Scopes 1 and 2 concerning Aena and Luton differ from those published on the 2020 Aena Non-financial Information Report, due to these being updated with the consolidated consumption data and emission factors for 2020.
