dalgoma Posted January 22, 2012 Share Posted January 22, 2012 If all the tyres of all the vehicles in the world was replaced with CO2, what would it do for global warming? Link to comment Share on other sites More sharing options...
insane_alien Posted January 22, 2012 Share Posted January 22, 2012 if we call it a gigaton of tyre and convert that to 1 billion tons of CO2, probably not that much assuming its a one off spike of CO2. you wouldn't increase the concentration of CO2 by much (2 parts in 10^10) its a fair fraction of the 2008 CO2 release from fossil fuels, (31.8 gigatons). It wouldn't be good, but it probably wouldn't cause drastic and immediate effects like the mediterranean evapourating or the antartic icesheets sliding into the sea.

dalgoma Posted January 23, 2012 Author Share Posted January 23, 2012 Assuming that the air in tyres is at 2 bars, you would be releasing twice the volume into the atmosphere and replacing it with CO2 would isolate quite a lot of CO2! Link to comment Share on other sites More sharing options...
Essay Posted January 23, 2012 Share Posted January 23, 2012 How much CO2 would be produced, by the work needed to compress the gas, that would go into the tires? Link to comment Share on other sites More sharing options...
insane_alien Posted January 23, 2012 Share Posted January 23, 2012 oh you mean you want to fill the tyres with CO2. then you wouldn't remove very much. a few million tons perhaps. less than a days worth of CO2 emissions anyway. Link to comment Share on other sites More sharing options...
