- Addressing barriers to increase the availability and affordability of SAF
- Understanding and reducing environmental impacts associated with the goods and services we purchase to run our business
- Climate-related physical risks (extreme weather, flooding, sea-level rise)
- Climate-related transition risks (uncertainty of future supply of fossil jet fuel, uncertainty of future SAF availability and cost-competitiveness, policy/legal risks associated with carbon pricing, policies and regulations to mitigate climate change, behavioral changes and development of alternative transportation modes, lack of technology advancements)
