Question 1

Why do premium cabins have higher emissions?

Accepted Answer

Premium seats occupy more aircraft space, reducing passenger capacity. The flight's total emissions are divided among fewer passengers.

Question 2

What is radiative forcing?

Accepted Answer

Emissions at high altitudes have greater climate impact. A factor of 1.9 is applied to account for contrails, cirrus clouds, and nitrogen oxide effects.

Question 3

How can I reduce my flight emissions?

Accepted Answer

Fly economy class, choose direct routes, avoid short flights where trains are viable, and consider video meetings instead.

Question 4
