A Hummer parked in a garage emits almost zero CO2 over the course of a year.
The Hummer H2 gets around 10 to 12 mpg. Assuming the typical owner drives 15,000 miles per year, that is around 1300 gallons of gas. Each gallon of gas burned results in 14 pounds of CO2. Multiplying these last two figures we get 9.5 tons of CO2 emitted per year, per Hummer, on average.
100,000,000
It depends on how much electricity it is using. Most electricity is generated by burning fossil fuels, which produces carbon dioxide.

A 757 using 60-80 tons of fuel per day produces 200-300 tons of CO2. A typical car produces 3 tons per year of CO2, therefore one 757 produces the same as 20,000-30,000 cars.
Carbon dioxide emissions vary depending on the fuel. Natural gas (the cleanest fuel) produces about 117 lb CO2/106BTU. Coal, on the oter hand, produces about 225 lb CO2/106BTU. Liquid fuels (gasoline, diesel and furnace fuel) are in the middle of the range.
An average car produces about 7700 kg of co2 a year.
350 kg
it produces 13 metric tones of co2
The Hummer H2 gets really poor gas mileage, somewhere in the range of 10 to 12 mpg. The Bugatti Veyron gets only 10 mpg, but it probably emits less CO2 overall as these tend not to be driven as much as the H2.
sulfur oxide
It saves around 350kg of co2 a year
The average Canadian produces approximately 23 tonnes of Greenhouse gasses.
Too much !
Carbon dioxide (CO2)!It produces sulfuric oxides. (This was written by a 12 year old.)
Please spell out "CO2"
A LOT less than a Hummer! Over the life of 200K miles, if the same numbers are used, the Prius will create about 38 tons of C02 About 1/2 as much as a regular internal combustion engine car. A Hummer on the other hand, will create 190 tons of C02. 152 tons more than a Prius. See the analysis here: http://rodgerswriting.blogspot.com/2012/06/hummer-versus-prius.html
