Sustainable aviation is essential
Sustainability is becoming the #1 issue for the aviation industry. It accounts for ~2.5% of global emissions and ~4-6% including non-CO2 effects, with the share set to grow over time. Aviation is committed to net carbon neutrality by 2050, but to make this transition a reality, there is an urgent need for more investment and greater collaboration.
The industry is not yet on track to achieve it
Whilst many individual players have plans and initiatives, collectively the industry is falling far short of what is required. Under current, business-as-usual scenarios, aviation emissions are set to rise by 2% per year. Sustainable Aviation Fuel (SAF) currently costs between 2 and 5 times the cost of regular jet fuel and accounts for only 0.1% of current fuel volumes. Given limited historical investment we are decades away from meaningful adoption of low emissions propulsion technologies for large, long-haul aircraft.
The solution is technology & collaboration
Only 25-40% of emissions can be reduced through efficiency gains; 60-75% require investment in new technology innovation and commercialization. Long investment cycles mean we need to find industry scale solutions in the next ~10 years. Typically, it takes time to implement new innovations in aviation and current funding is a mere fraction of what is needed for meaningful impact.
