The 4th Aviation & Environment Summit - the only global summit of aviation environment leaders - was held in Geneva on 31 March and 1 April. This year, we reported on progress towards the goal of carbon neutral growth highlight the effect the 2008 Declaration has had on the industry - particularly when it comes to coordinated action. This was done through expert panels and speakers in two major workstreams: driving aviation efficiency and harnessing the potential of alternative fuels.

We have an impressive line-up of speakers and panellists from the industry, academic research institutes, environmental and sustainable development NGO's, technology providers, fuel and biofuel development organisations and governments.
