In order to monitor and reduce its CO2 emissions, Turin Airport has participated in the Airport Carbon Accreditation (ACA) programme of ACI Europe (Airports Council International) since 2017 and has been accredited at Level 3+ (Neutrality) since 2024.

Emissions, calculated in accordance with the ISO 14064 standard and the GHG Protocol, are broken down as follows:
 

• Scope 1: direct emissions

• Scope 2: indirect emissions resulting from the production of electricity and thermal energy

• Scope 3: other indirect emissions
   

The certification requires the implementation of a plan to reduce emissions directly under the airport’s control and the development of a plan to engage stakeholders in the decarbonisation process.

The measures undertaken have made it possible to reduce emissions per passenger by more than 80% compared with the 2017 baseline year. The objective for the current three-year period is to maintain a reduction of more than 85% in specific emissions compared with the baseline year and achieve a reduction of at least 5% compared with the average of the previous three-year period.

The residual emissions generated in 2025, amounting to 1,895 tonnes of CO2, were offset by financing two projects that comply with the Airport Carbon Accreditation guidelines (https://www.airportcarbonaccreditation.org/technical-documents/).

The main characteristics of the selected projects are outlined below:

• The first, called the “The Kasigau Corridor REDD Project”, is a forest conservation project located in the Kasigau Corridor in south-eastern Kenya. It is a REDD+ project aimed at conserving the forest ecosystem, mitigating climate change and providing socio-economic benefits to local communities. The project has been certified by Verra under the VCS (Verified Carbon Standard) and CCB (Climate, Community & Biodiversity Standards). A total of 359 credits were retired for this project.

• The second is called the “Bolu Landfill Gas to Energy Project” and concerns an integrated solid waste management system at controlled and uncontrolled landfill sites in the city of Bolu, Türkiye. The project involves the collection and combustion of landfill gas at a facility located within the site itself in order to generate electricity and feed it into the national grid. The project has been certified by Gold Standard, and the methodology applied has been approved by ICVCM, which classified the project as “CCP eligible”, ensuring that its environmental and social impacts are verified and transparent. A total of 1,540 credits were retired for this project.
