How can we ensure global air mobility that minimizes resource use and climate effects?

Sigrun Matthes is a researcher at the DLR and coordinator of the FlyATM4E project. In the following video she answers the above question, and also offers some explanations on the following ones:

• What does the climate effect of aviation consist of?
• How do scientists address climate uncertainties in their estimates to ensure that proposed solutions have a reduced climate effect?
• How does the FlyATM4E project act to provide airspace users with climate-optimized alternative trajectories?
