Africa’s first solar powered airport officially opened in February 2016, as the Garden Route's George Airport made the switch to off-the-grid power.
With a massive uptake in air travel and an ever-growing aviation sector, sustainable airports are becoming increasingly crucial in securing the safety of ecosystems.
Here are the world's most eco-friendly airports:
Sweden: Stockholm Arlanda International Airport
It was the first European airport to achieve carbon neutrality in 2009. The airport’s goal is to have a zero-carbon footprint by 2020.
Galapagos Islands: Seymour Airport
Known for continually fighting any harmful impact of tourism on the environment, the Galapagos Islands Ecological Airport is 100% green and runs on solar and wind power. Its infrastructure was created using over 80% recycled materials.
Singapore: Changi Airport
The new Terminal 4 houses over 20000 plant species and is a hub of eco-friendliness. It features energy-efficient motion sensors, lighting, runs on solar and has water-efficient fittings.
US: Denver International Airport
Home to the largest solar power farm at a commercial airport in the US, it generates enough electricity to power 2500 homes.
India: Indira Gandhi International Airport
India’s largest international airport saves on energy by using battery-powered vehicles to transfer passengers between terminals and to baggage claim.
Switzerland: Zurich International Airport
Extremely eco-conscious, the airport uses rainwater in the toilets and utilise underground energy piles in order to heat and cool its terminals.
Norway: Oslo Airport
Snow is gathered from the runways and stored in an onsite depot; it is then used in summer as a coolant.
