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.
The burning of fossil fuels for electricity and heat production is the largest source of CO2 emissions worldwide. Other significant sources include industrial processes, transportation, and deforestation.
Burning fossil fuels releases carbon dioxide (CO2) into the atmosphere. The amount of CO2 emitted depends on the type of fossil fuel and how it is burned, but on average, burning one gallon of gasoline produces around 20 pounds of CO2. This is a major contributor to the greenhouse effect and global warming.
On average, natural gas combustion produces around 117 pounds of CO2 per million BTUs, while coal combustion produces around 205 pounds of CO2 per million BTUs. This means that using natural gas instead of coal can result in a reduction of around 88 pounds of CO2 per million BTUs.
Volcanoes emit varying amounts of CO2 depending on their activity levels. On average, volcanoes release about 200 million tons of CO2 per year. This is a relatively small amount compared to human-generated CO2 emissions.
Approximately 40 billion tons of CO2 are emitted into the atmosphere each year from human activities, such as burning fossil fuels, deforestation, and industrial processes. This has led to an increase in the concentration of CO2 in the atmosphere, contributing to global warming and climate change.
An average car produces about 7700 kg of co2 a year.
350 kg
A Bugatti Veyron produces around 596 grams of CO2 per kilometer driven.
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.
Burning 1 kg of LPG produces approximately 2.98 kg of CO2.
Burning 1 kg of petrol produces around 2.3 kg of CO2.
It saves around 350kg of co2 a year
Too much !
Burning one liter of furnace oil produces approximately 2.6 kg of CO2 emissions.
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
On average, a person produces around 20 metric tons (44,000 pounds) of CO2 per year through activities such as transportation, energy use, and food production.
Please spell out "CO2"
