Cleanliness of natural gas?

Question

My sister's car runs on natural gas (Italian 'Dino farts') How clean is this compared with petrol (gas) for C02 and air quality?

Answer 1

U will produce almost the same amount of CO2  if u do the same work.

Answer 2

When we burn boiloff gas from the LNG carrier I work on, there's no visible smoke coming out the stack.   When we burn bunker fuel, it is clearly visible.   Bunker fuel (or gasoline for that matter) is mostly carbon with hydrogen and other elements added in in smaller amounts.   Natural gas is mostly methane, which is CH4- 4 hydrogen atoms for every carbon atom.

Answer 3

NATRAUL GAS= GOOD

Answer 4

IF you are comparing two well tuned cars then there will be little difference in CO2 output.  There will be a significant benefit to air quailty particularly in respect of particulates which cause lung damage. Also gas is easier and less environmentally damaging to extract and transport in the first instance.

I should point out it is nowhere near as environmentally friendly as bio-ethanol, or hydrogen from a renewable source.

Answer 5

Natural gas burns quite clean.  The natural gas Honda Civic (GX) emits 129 g/km of CO2.

In comparison, the Civic hybrid has 116 g/km, Civic SE has 160 g/km, and Prius has 104 g/km.  So basically it has higher CO2 emissions than hybrids, but lower than regular gas cars.  I believe it's quite good in terms of other emissions as well.  Yahoo Autos has it ranked just slightly behind the Prius and Civic hybrid in their top 100 green cars list.
