Farm Animals Versus Cars and Vans

Greenpeace have produced one of those 'wow, I never thought that!' calculations. They have worked out, that if you add in the figures for changes in land use and deforestation, the collected farm animals (mainly cows and pigs) of the EU have a bigger greenhouse gas impact than the emissions from all cars and vans in the bloc (https://www.greenpeace.org/eu-unit/issues/nature-food/45051/animal-farming-in-eu-worse-for-climate-than-all-cars/). This, of course, requires converting the very potent methane generated in cow burps, into carbon dioxide equivalents. They suggest that this means that the EU will have to reduce the emissions generated by its meat and dairy industries to get anywhere near the target for arresting climate change. I certainly agree that they must be part of the calculation. What about, however, the emissions associated with trucks, shipping and aircraft, as well as with concrete production for building? This is not to mention, electricity production and sections of heavy industry and waste disposal. I would also ask people to note, that the stocking densities of EU animals, doesn't even approach that of the mega-farms in the USA, Brazil and Australia. The calculation might impress some people sufficiently to reduce the meat and dairy content of their diets (I hope it does) but this is 'small beer' when weighed against the contributions to climate change made by other activities (over which most members of the public have little control).
