2.4%Aviation contributes an estimated 2.4% of global annual CO2 emissions, most of it from commercial travel. However, Klöwer said, “Most people think of warming in terms of degrees, not tons of carbon emitted, so we wanted to calculate that.”Cached
How much pollution does a plane produce?
CO2 emissions from aviation fuel are 3.15 grams per gram of fuel [1], which gives CO2 emissions from a Boeing 737-400 of 115 g per passenger per km. At a cruising speed of 780 km per hour [Wikipedia, 28.2. 08], this is equivalent to 90 kg CO2 per passenger per hour.
What are the top 3 contributors to air pollution?
Vehicle and industrial emissions from fossil fuel combustion, cigarette smoke, and burning organic matter, such as wildfires, all contain PM. A subset of PM, fine particulate matter (PM 2.5) is 30 times thinner than a human hair.

Who is the biggest contributor to air pollution?
transportationCars, trucks, and buses powered by fossil fuels are major contributors to air pollution. In fact, transportation emits more than half of nitrogen oxides in our air, and is a major source of heat-trapping emissions in the US.
What is the #1 source of air pollution on Earth?
Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources.

What is biggest contributor to climate change?
Fossil fuelsFossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun's heat.
