Green Airport 

A green airport is one which has a minimal impact on the environment and aims for zero gas emissions.

Green airport project

A green airport uses responsibly the natural resources it needs to function, reduces energy consumption and promotes the use of renewable energy in order to reduce greenhouse gas emissions, and manages its waste appropriately. To sum up, an airport that has a minimal impact on its environment and aims to be a carbon neutral facility (zero gas emissions).

Aena has taken another step to remain at the forefront of environmental policy, launching its 'Green Airport' project with Lanzarote Airport, where specific projects will assess the different technologies available for minimising energy consumption and CO2 emissions, until it can be certified as carbon neutral or a “green airport”.

At the same time, possible fields of action can be identified, both in airport activities and in aircraft movement, areas where the viability will be assessed of using new technologies, more efficient from the standpoint of energy consumption and carbon emissions. The possibility will also be assessed of generating renewable energy by installing photovoltaic panels and wind turbines, or using biomass plants.

Aena is exploring the various technological advances aimed at improving energy efficiency. Reducing consumption and favouring the production of energy from renewable sources is one of the objectives of this project, which will also serve to promote collaboration in the development and implementation of these measures with the airport operators and concession holders, and with the manufacturers of this technology. After assessing the viability, effectiveness and profitability of these technologies and of new operational procedures, it will be essential to check that putting them into action ensures the airport is operational and safe.


These are some of the proposals included in the 'Green Airport' project to achieve a 20% reduction in the short-term of CO2 emissions, which cause climate change and global warming.


  • Renewal of ground services with mobile equipment.
  • Installation of more efficient precision approach path indicators (PAPI), enabling a saving of 21 to 48%.
  • Reduction in the time and distance aircraft have to taxi to and from boarding gates, using a single engine to save fuel.
  • Supplying ground support services to aircraft using an underground tunnel system with retractable equipment.
  • Installation of LED devices in aeronautical ground lights, taking advantage of their high performance and low maintenance costs.


  • Efficient control of heating, cooling and lighting, with the installation of photovoltaic panels, wind turbines and geothermal heating and cooling systems.
  • Use of LEDs and replacement of lights with fuel economy, high efficiency bulbs, favouring the use of spaces which enable more natural light.
  • Advanced parking system consisting of sensors and indicator lights, in order to save energy and reduce noise and pollution.
  • Replacement of conventional vehicles for more efficient models using electricity and natural gas.
  • Possibility of installing blinds or deciduous plants in parts exposed to the sun, favouring shade in summer and sunlight in winter.
