Most additional CO2 comes from human activity, which adds approximately 30 billion tons per year world wide. Dividing by 365 that amounts to 82 million tons of CO2 per day.
The average person produces about 2.3 kg (5.1 lbs) of CO2 per day through respiration. Therefore, 10 people would produce approximately 23 kg (51 lbs) of CO2 in one day.
Too much !
I have found simple statistics for people (each person releases about 800 lbs of CO2 in a year) and automobiles (about 11,000 - 17,000 lbs of CO2 per year) but when I looked for simple numbers for coal burning power plants (which I suspect are major factors in CO2 production) I found an overwhelming about of statistical information. I could not find a source that gave me the simple average Answers.com of CO2 released per year
The primary gas discharged by volcanoes is not CO2 by H2S, hydrogen sulfide. Currently Mt. St. Helens is Washington's top polluter, emitting about 100 tons of sulfur dioxide per day. Previously that distinction would have gone to one coal fired plant near Centralia, which emitted 200 tons of H2S per day until state regulators insisted on renovations which brought the emissions down below 30 tons per day. The eruption released somewhere in the neighborhood of 200,000 tons of CO2. In contrast, humans emit about 30,000,000,000 tons of CO2 per year, or 150,000 times as much. According to the USGS, that is well over 100 times as much as all earth's volcanoes combined.
60% of crude oil imported into the US is burned as fuel (cars, trucks, power plants). One barrel of crude oil makes about 317 kg of CO2. The US consumes about 9,286,000 barrels/day (of gasoline, assuming it produces the same CO2 per barrel...). One average person produces about 0.90 kg of CO2 per day. The US alone produces the CO2 of 2.9 trillion people. China has the US beat on the production of CO2 also.
The molar mass of CO2 is approximately 44 grams per mole.
A Bugatti Veyron produces around 596 grams of CO2 per kilometer driven.
3 time a day per a day do not feed them to much
once per day
Doesn't the driver ( and any passengers ) in the car emit CO2 as well, so you are not comparing like with like.You must compare CO2 from Car, driver and passengers with CO2 emitted by cyclist to be more accurate.You will need to divide the CO2 for car driver and passenger by number of occupants of car to get CO2 per person per journey
The Eyjafjallajokull volcano in Iceland released an estimated 150,000 tons of carbon dioxide per day during its eruption in 2010. However, volcanic eruptions are known to release a combination of gases, including sulfur dioxide and water vapor, in addition to carbon dioxide.
