• Tax fossil fuel aviation fuel.
• Invest in university research on zero emission technologies, such as electric and fuel cell aircraft. Zero tax electric or fuel cell aircraft.
• Demand planes move to flying exclusively with sustainable fuels, produced from agricultural and household waste. Instead of fossil fuels.
• The typical problem with biofuel is not difficulty in using it, but simply cost. They can often cost as much as twice the price of older, more established fuels.
This needs government solutions.
• Norway uses forest waste to manufacture
bio-aviation-fuel.
• Scientists have also made bio-aviation-fuel using the grease from restaurants (cooking oil) and sewers (a use for what causes blockages down there).
• Research safe and green hydrogen fuel for aircraft and trains.
