In partnership with Many have received significant government ambitious senior leadership across industry, financial support to remain in business, while government, and civil society, this public-private others have collapsed or declared bankruptcy. partnership is driving a shift to zero-emissions Recovery is expected, albeit slowly. As public aviation through sustainable aviation fuels (SAF) health experts learn more about the SARS- and other clean propulsion technologies. COV2 virus, international travel standards will improve. When governments reopen SAF is a necessary step in aviation’s borders and consumer confidence returns, decarbonization pathway, especially with next- air travel will again become commonplace. generation technologies like electric flight and hydrogen-powered propulsion still years away But in the meantime, climate goals must be from application at scale. The CST coalition is met and the clock is still ticking on this decade working to address the chicken-and-egg scenario of delivery. Encouragingly, CST’s stakeholders whereby producers and consumers of SAF are have shared that both individual and corporate both either unwilling or unable to carry the initial customers are demanding more sustainable cost burden of investing in new technologies to travel options. In line with the Forum’s Great reach a scale where they are more cost competitive Reset initiative, guiding decision-makers along with existing fossil fuel-derived options. the path to a more resilient, sustainable world beyond coronavirus, CST continues to accelerate The aim is to break this impasse and advance the the energy transition of the aviation sector. As commercial scale of viable production of sustainable the International Organization for Public-Private low-carbon aviation fuels (bio and synthetic) for Cooperation, the World Economic Forum is the broad adoption in the industry by 2030. This report, ideal platform to inform, support and accelerate developed in close consultation with the CST this transformation. coalition, serves to provide a fact base on which swift and bold actions should be taken by public Along this journey, we are consistently encouraged and private sector leaders alike. by the CST coalition members and partners who through their engagement reinforce their commitment The COVID-19 pandemic, however, continues to to achieve sustainable and climate-neutral flying even have profound effects on society, economies and in this challenging time.

Clean Skies for Tomorrow: Sustainable Aviation Fuels as a Pathway to Net-Zero Aviation 4 Executive Summary A transition to carbon-neutral flying is possible and sustainable aviation fuels are the most promising decarbonization pathway in the near term. Climate change is one of the most urgent Aviation is one of six hard-to-abate sectors which, challenges of our time and requires collective along with cement, steel, plastics, trucking and action to solve, embodied in a shared vision and shipping, represent approximately 30% of global collaboration across government, industry and annual carbon emissions. According to the society. The decade until 2030 is our window European Commission, by the middle of the 21st of opportunity to shift the global trajectory to a century demand for flying could increase aviation’s sustainable future. Indeed, the actions taken now GHG emissions by more than 300% over 2005 will determine the ability of future generations to levels, although this increase has been temporarily sustain themselves on this planet. slowed by the COVID-19 pandemic.
