We know that carbon dioxide from aircraft contributes to global warming but what about other aircraft emissions? One of these, Nitrogen oxide (NOx), creates one greenhouse gas (ozone) but helps to destroy another (methane).

Which effect is more important? Furthermore, if we reduce NOx emissions we will probably have to increase CO2 emissions. What is the best trade-off between these gases? And should we deliberately seed the stratosphere with

SO2 in order to reflect some of the sun’s rays?

This talk investigates the feasiblity of a ‘chameleon plane’, which examines the air outside and adjusts its emissions to be as envionmentally invisible as possible.
