Research group forecasts switch to green long-haul aviation will significantly increase costs

US-based research and advisory group Lux Research senior director Christopher Robinson has warned that the switch away from fossil-based aviation fuels to environmentally sustainable alternatives could significantly increase the cost of flying, particularly for long-haul flights. He did so in a recent blog post. He reported that the decarbonisation of aviation was one of the topics that the company’s clients raised most with Lux, last year. Currently, total annual aviation carbon emissions came to just under 1 Gt. And commercial aviation was forecast to grow strongly in the coming years.
