This week's Open Mic guest is Tom Michels, Director of Government Affairs for United Airlines. Global aviation fuel demand is near 100 billion gallons annually and farmers can play a crucial role in producing renewable fuels for a portion of that demand. United Airlines continues to not only consume but invest in sustainable aviation fuels. Michels says the market shows tremendous opportunity to lower the environmental footprint for the airline industry while providing sustainable solutions for airline carriers, but federal and state policies have substantial impact on the outcome.
