Planes contribute to about 2-3% of global carbon dioxide emissions from human activities. This percentage is expected to increase as air travel continues to grow unless more sustainable aviation practices are implemented.
I would presume so, Much higher fuel consumption so higher emissions.
76%
In the 1920's, fighter planes cost about 50,000 per plane to produce. However, some were as expensive as 1.5 million dollars to produce.
About 20%

Good aerodynamics and as much power as possible (emissions and reliability, being the deciding factors).

Wind power is not generated by countries, it is a global phenomena.
The US is responsible for around 15% of the world's carbon dioxide emissions from burning fossil fuels. This makes it one of the largest contributors to global greenhouse gas emissions.
every 2,062 miles travelled accounts for 1 ton of Carbon Dioxide emissions per person.
Termites produce around 11-30 million metric tons of methane annually, making them one of the largest natural sources of methane emissions.
propeller planes weight depends on how, tall it is, how wide it is, and how much cargo it has.
