Researchers, with monitors, have estimated that the 16-day long Oktoberfest of beer and bratwurst consumption in Munich generates about 1500 kg of methane (https://www.theguardian.com/environment/2019/oct/27/oktoberfest-munich-methane-emissions-environment). Methane is, of course, a highly potent green-house gas which can have a powerful effect on climate change. The workers reckon that most of the methane is generated by inefficient cooking but around 10% is emitted from the mouths and backsides of the drinkers.
