Who hasn’t been standing once in front of the supermarket shelf and asked oneself if the organic carrots from Italy or the cauliflower from the own country is the most ecological choice for the next meal, and then, finally, has decided to buy the delicious asparagus from the USA? Food is one of the three most important consumption fields regarding total environmental impacts. The extent of environmental impacts depends on various factors. It is not easy for consumers or even for experts to account for these impacts. Niels Jungbluth has conducted several projects in the last 25 years aiming to facilitate such judgements. The presentation will show several aspects for investigating the environmental impacts of food production and consumption. It also show which strategies should be followed to reduce these environmental impacts.
