Navigating the politics of airport growth

Airport growth is increasingly limited by environmental restrictions. With the worldwide air traffic demand increasing, many of the world’s airports are reaching the limits of their environmental capacity. However, further development is often a political minefield. We think smart management of community relations can help. Pushing...

Changing the environmental impact of aviation: evolution over revolution

Earlier this month, the UN’s International Civil Aviation Organisation (ICAO) member states ratified the Carbon Offset and Reduction Scheme for International Aviation (CORSIA). This scheme takes effect in 2021, and even then, it is voluntary until 2027. Not exactly a swift ‘green’ revolution. Why so...
