Reducing aircraft emissions globally will require effective regulations

Aviation emissions are a major clause of climate change, writes Valerie Brown - yet they remain unregulated. The gap between the best and worst performing airlines demonstrates ample opportunities for improvement - but is the political will there to impose effective regulation?

The performance gap suggests the industry could reduce GHG emissions significantly if the least efficient airlines would emulate the most efficient.

If commercial aviation were a country, it would rank seventh in global greenhouse gas emissions according to a recent report by the International Council on Clean Transportation(ICCT).

The aviation industry is growing so quickly that its greenhouse gas (GHG) emissions are expected on present trends to triple globally by 2050. The industry itself is committed to reducing its emissions, but technological and political constraints are hindering rapid progress.

Technologically, the fate of aviation GHGs depends on how much more fuel-efficient airplanes can become, and how soon lower-carbon fuels can be made available at a palatable cost.
