well everyone is thinking about CO2 no-one is really caring about our holy beer that really :(

well if 62.2 gms of mass is missing from beer in the form of Co2 from 1 lts then i think its a lot of fun that we missing :P
ok now on theory
we r having 2-3% v/v of co2 is dissolved in the beer itself.
plus almost all that Co2 that is produced by the beer or any fermentation industry is recovered by the co2 recovery system and filtered and that co2 is reused for some process.

I believe that carbon monoxide (CO) is much worse than carbon dioxide (CO2). Pine trees contribute to the CO in my area, and they provide much greater tax incintives…

What is the world-wide annual production of alcohol? Can one determine from this how much CO2 was created in its production? Then what is the percentage of this fermentation CO2 to the total annual man-produced CO2?

Knowing the effect of my martinis on the environment may help me to cut back.

Or if the amount of CO2 is trivial in comparison to the total, I won’t cut back.

p.s. And how about carbonated soft drinks?

Most? I don’t know of any.

Yes, but most breweries of any size have CO2 recovery plants in house that capture and re-use this by product for the carbonation process. It is misleading to imply that all the CO2 produced during fermentation becomes an emission to the atmosphere.

All of this CO2 is from grain which is grown on an annual basis, meaning that there is no net C02 produced by this process. If beer were made from oil, this would be a concern…otherwise it is like calculating your CO2 footprint on your compost.

Interesting!
Homer Simpson would be very angry. Plus if there was no beer, what would I drink while driving my H2 around.

Any data on CO2 emmissions from winemaking? and… shall we start compensating also for emmissions other that from burning fossil fuels (apart from breathing…)
Any comments from any Wine Association?

One other point in favor of beer is that it is a renewable resource (Yay beer!). The carbon emissions are part of a natural cycle.
The British Beer & Pub Association quotes that “The amount of carbon dioxide released during fermentation is roughly a quarter of the amount absorbed from the atmosphere through photosynthesis by the growing grain.”.
Now, who would not trust a beer an pub association for their word?
