Carbon footprint | Corporative

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.

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 is the evolution of Aena's carbon footprint equivalent in tonnes of CO₂:

The table includes the tCO2e emissions of Aena SME SA and SCAIRM for the 2019-2022 period, verified in accordance with the UNE-EN ISO 14064-3:2019 criteria, with a limited safety level, under the GHG Protocol calculation methodology, and in the case of the 2023 footprint in accordance with the requirements of the International Standard on Assurance Engagement ISAE 3410, using the calculation procedure outlined in the following document:
