TED: 3 ways to make flying more climate-friendly | Ryah Whalen

The video discusses the environmental impact of air travel, highlighting the personal conflict between the desire to travel and the need to reduce carbon emissions. It explains the challenges of decarbonizing aviation, including the reliance on traditional jet fuel and the long lifespan of aircraft. The video explores solutions such as redesigning planes, using biofuels, and developing new technologies like synthetic fuels and hydrogen. It emphasizes the need for industry collaboration and personal responsibility to achieve zero emissions by 2050.

What percentage of global CO2 emissions is currently attributed to aviation?

• 2%

• 15%

• 5%

• 10%

Why is traditional jet fuel challenging to replace in aviation?

• It is not widely available.

• It is too expensive.

• It is not energy dense.

• It is deeply integrated into current aviation infrastructure.

What is a major limitation of biofuels in aviation?

• They produce more emissions than traditional fuels.

• They are not renewable.

• They require a lot of water.

• There is limited feedstock available.

What is the European Commission's proposed biofuel usage mandate by 2035?

• 20%

• 10%

• 25%

• 15%

Which of the following is a potential future fuel for aviation that involves capturing carbon dioxide from the air?

• Biofuels

• Synthetic fuels

• Traditional jet fuel

• Natural gas

What is a blended wing body design in aircraft?

• A design with no clear dividing line between the wings and body

• A design that uses only one wing

• A design with separate wings and body

• A design that is not fuel efficient

What is a key factor in achieving zero emissions in aviation?

• Reducing the number of flights

• Collective action and collaboration across the industry

• Individual countries working independently

• Relying solely on traditional jet fuel
