Carbon Dioxide Emissions

Damon Matthews who is a professor in Concordia University's Department of Geography, Planning and the Environment has just completed a study with another group of scientist from Victoria and Britain concerning carbon dioxide emissions. Their results which will be published today in Nature, reveal that for every tonne of carbon dioxide released into the environment, there will be a 0.0000000000015 degrees of global temperature change. Furthermore, the findings indicate that it does not matter over what time period the emissions occur.

So what is the volume of 1 tonne of CO₂?

1 tonnes = 1 000 kg = 1 000 000 g
1 m³ = 1 000 L
1 mole of CO₂ = 12 g + 2 ( 16 g ) = 44 g
1 tonne contains 1 000 000 g / 44 g/mole = 22730 moles of CO₂
According to Boyle's law, at 25˚C and 1 atm, 1 mole = 24.47 L
Therefore, 1 tonne of CO₂ = 22730 moles х 24.47 L/mole = 556200 L = 556.2 m³
