“The first one is the one which we are normally focussing on in our policy life. Why? It's easier. It's not contagious,” noted Potocnik.
“The second one is problematic, because it's addressing people's dietary choices and has major consequences also on the structure of European agriculture. That's why nobody is pretty much from the policy trying to address it,” he added.
But dietary changes would have great effects.
According to the authors, if all Europeans cut their meat consumption in half, this would result in 43 percent lower ammonia emissions, 31 percent lower nitrous oxide emissions, and 35 percent lower nitrate emissions - that is if the cuts are accompanied by a reduction in European livestock, and not a shift to exports.
