Can airlines pivot fully to biofuels?
As pressure grows on airlines to reduce their climate change impact, and \u201cflight shame\u201d grows among people concerned about their own impact, ever more research is being put into alternative, \u201ccleaner\u201d sources of fuel. Katie Prescott travels to Oslo to see new projects to bring more so-called biofuels into the system. Air BP\u2019s commercial development manager, Tom Parsons, explains the difficulties in implementing and costing biofuels, while Dr Andrew Welfle at the University of Manchester describes the potential sources and applications of biofuels.
