What are the co2 emissions (in lbs per gallon) of a CNG bus?

I cannot find this for the life of me. I know that typically 19.4 lbs of co2 are released for every gallon of gasoline, but I need to know how much compressed natural gas (CNG) produces!!!
CNG or compressed natural gas, (CH4) is a compressed gas and not a liquid. It is not typically measured [...]

Why has 0bama cut n run on Copenhagen? Shouldn’t he just cut our CO2 emissions to zero via green jobs?

… and all that wonderful technology he swore he would create?
Why does he care what other countries do about CO2? Shouldn’t he just lead the way, set an example and cut our emissions to zero? Besides, didn’t he promise we would get wealthier in the process via green economy?
THE PROBLE IS THAT THE "AMERICAN [...]

isn’t the atmosphere too large to be affected by human CO2 emissions?

Let me start by saying that i am a strong believer in AGW.
A recurring argument presented by the deniers is that "the atmosphere is far to large to be affected by human emissions of CO2", would someone be able to explain to me why this is not the case?
Thanks.
The atmosphere may seem to large to [...]

What effect would a drastic reduction in carbon-dioxide emissions have on plant life?

With all the propaganda about "global warming", "global climate change", and being "carbon neutral", has anyone thought of the effects a drastic reduction in carbon-dioxide emissions would have on plants that need C02? If we reduce carbon emissions enough to make any difference in the climate, wouldn’t it have a negative impact on our [...]

My car just failed emissions because the air/fuel mixture is too rich? What fixes this problem?

And how expensive is this going to be?
It’s a 2000 Chevy Cavalier
And, yes, engine light is on.
needs a tune up. plugs, wires,cap and rotor. fuel injection or carb? if carb it could need adjustment. if fuel injection pobably the o2 sensor,but could also be, map sensor, maf sensor or egr valve. what kind of car [...]

Carbon Emissions and how they affect the different Earth Systems?

Ok I was wondering how all the carbon emissions that cars release into the air affect the different Earth systems, such as the Lithosphere, Biosphere, Hydrosphere, and the Atmosphere. Please try to include how it affects all of the Earth systems but if you know just about 1 please let me know. Also can you [...]

Briefly, what is a continuous spectrum, an emission spectrum and an absorption spectrum?

Briefly, what is a continuous spectrum, an emission spectrum and an absorption spectrum?
continuous, it has output at every frequency over a band.
emission, the output is on a small set of discrete fixed frequencies
absorption, is the same as continuous except that there are a small set of discrete fixed frequencies at which there is not output.

What is the co2 emission for bio diesel compare to ordinary diesel fuel?

How is this calculated and why is bio diesel so popular?
CO2 emissions are very similar to emissions from petrodiesel. The difference is, this is carbon that’s extracted from something that was alive recently, generally a plant (it is possible to make biodiesel from animal fat, but that is not done). Plants absorb CO2 [...]

How many newspaper/magazine pages would i have to recycle to offset my cars CO2 emissions?

I have a Peugeot 306 1.9 diesel car. This is 11 yrs old and the handbook says it emits 165g of CO2 per KM. I have a journey of 13 miles to get to work with is mostly extra urban driving at 60mph. How many newspaper /magazine pages would i have to recycle to offset [...]

Can the US best reduce global CO2 emissions by reducing trade with China?

US manufactures are more efficient and produce less CO2 than their Chinese competitors.

Should the Obama administration put a high carbon tax on Chinese imports (and other high emission countries)? Can Americans go green and reduce their $200 per person per month trade deficit by buying US made goods?
Several thoughtful answers. Lets see where [...]
