Overall jetfuel demand (growth of aviation sector, specific jetfuel demand)
Overall biojetfuel availability (availability of advanced biojetfuel production technologies, infrastructure and logistics for large scale production, progress in plant breeding)
Environmental effects (Carbon burden of jetfuels, carbon burden of biojetfuels, effects of additional greenhouse effects)
Market development (development of oil price, development of biojetfuel prices, development of CO2 prices and/or further regulations, further regulations for other emissions forcing the greenhouse effect)
International trade (standards for biojetfuel quality, sustainability certification for biojetfuels)
