The National Research Council of Canada (NRC) has released the results of a civil flight powered by 100 per cent biofuel which flew on October 29, 2011. A Falcon 20 flew on biofuel at 30,000 feet and displayed a 50 per cent reduction in aerosol emissions compared with conventional fuel. Additional tests performed on a static engine also showed a significant reduction in particles of up to 25 per cent and in black carbon emissions of up to 49 per cent when compared with conventional fuel. An improvement of 1.5 per cent in fuel consumption was also recorded, although engine performance remained comparable. John McDougall, president of the NRC, stated that “the data collected enables us to better understand the impact of biofuel on the environment".
