Inflammable means flammable? What a country!

From the BBC (emphasis mine):

Japanese car manufacturer Honda has begun the first commercial production of a zero-emission, hydrogen fuel-cell powered vehicle.

The four-seater, called FCX Clarity, runs on electricity produced by combining hydrogen with oxygen, and emits water vapour.

So..."zero-emission" means..."emits a greenhouse gas"?

That's a little odd.

I mean, greenhouse emissions are generally understood to be the anthropogenic ones, carbon dioxide, methan, nitrus oxide & CFC-12, right? But water vapour is still an emission. And along with the above, one of the most important greenhouse gases.

According to wikipedia, It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive.

& also, that human activity does not affect water vapour concentrations. THUS FAR. maybe with this car, it will be the next big project. which leads to this:

Current state-of-the-art climate modelspredict that increasing water vapor concentrations in warmer air will amplify the greenhouse effect created by anthropogenic greenhouse gases while maintaining nearly constant relative humidity. Thus water vapor acts as a positive feedback to the forcing provided by greenhouse gases such as CO2.
