OLGA's commitments directly align with 9 out of 17 Sustainable Development Goals of the United Nations. In this sense, the project will deliver environmental efficiency actions with the purpose of increasing performance from three perspectives.

Flight Operations 


OLGA Project will support a green Landing and Take-Off cycle (LTO) to a maximum extent. It commits to the urgent, complex reduction of aviation’s absolute CO2 emissions. Additionally, OLGA will ensure complete and traceable availability of Sustainable Aviation Fuel (SAF) for airlines.

The Key Performance Indicators are:

  1. The validated traceability process and system are in place to create transparency in the level of SAF use;

  2. Demonstration of ‘net-zero’ CO2 turnaround with auxiliary power units (APU) reduction, low carbon taxiing and ground support equipment (GSE), and SAF;

  3. Airports as “Hydrogen hubs” for ground vehicles (short term) and aircraft (long term) by demonstrating: (a) H2 production with an electrolyser, (b) H2 usage in mobility and (c) master planning of an H2 airport design.

Passenger and Cargo Transport


With a journey-centric approach, OLGA will decrease the direct environmental footprint of the airport itself related to passengers, staff and freight. After landing, passengers will benefit from a green, biodiverse environment along taxiways and better air quality. If parked remotely, a low carbon transfer will be used to the energy-efficient terminals powered by renewable energy (physical and market based). Passengers will be presented with means to reduce and recycle waste in and outside the terminal. The airport-city connection will be a low-carbon modality such as rail, electric/hydrogen/biomethane buses, e-cars, hydrogen taxis, and autonomous vehicles.

The Key Performance Indicators are:

  1. The increased modal share of low carbon transport for airport and city connections for the four OLGA airports, based on yearly assessments;

  2. Intermodal air-rail: (a) passenger luggage flight check-in at train stations; (b) new freight business models;

  3. 100% of the passengers are provided means and information for waste reduction;

  4. Measurement of energy savings from the start to the end of OLGA, with the implementation of innovative energy solutions in terminals, visible to more than one million passengers.

Community and Territories


OLGA will support community involvement most transparently and inclusively by reducing health impact, thus improving air quality, fostering low carbon construction and promoting biodiversity. This includes trade-offs with other aspects such as noise.

The Key Performance Indicators are:

  1. Improved air quality at airport landside and airside with near real-time monitoring of air quality in place and work on a better characterisation of emissions sources;

  2. Reduction by 60% of electricity consumption in aircraft stand lightning, based on feasibility demonstrated with on‐site implementation;

  3. Equal or improved biodiversity index at the airport (i.e. reverse the current biodiversity degradation).
