Diet

Shopping

With our diet and shopping habits we have an impact.

Smart food concept
In Central Europe, we require on average as much energy for food as we do for housing. With the help of a nutritional concept, our energy expenditure can be soundly reduced.

Local Produce
The purchase of local and seasonal produce brings large energy savings, that is, CO2 reductions. Food transportation amounts to a substantial part of the total energy requirements of food provision.

Avoid products from distant countries
Foods such as lamb from New Zealand, South American chicken, fish from Asia, or asparagus from the United States, consume through their long-distance transport a huge amount of energy.

Local Organic Produce
With the purchase of organic produce from the local farms, you are investing in your health and saving energy. Moreover, you are supporting the local economy.

Local drinking water
Much energy can be saved through what we drink. Local drinking water is the leader in our daily water consumption and requires neither energy for transport, nor packaging. Fresh orange juice from overseas needs large amounts of energy for delivery. In contrast, if manufactured in Switzerland out of concentrated juice, the energy required is about 10 times lower.

Less Meat
In order to save energy and reduce CO2 emissions you can contribute by moderating your meat consumption. Meat is not only expensive, it requires ten times more land to be produced as, for instance, cereal crops. The most CO2 intensive meat is that of ruminants (e.g. beef).

Eggs, milk and fish
Meat can be replaced with other protein-containing substitutes such as eggs, milk and fish. In case these are also coming from local farms, the energy spent will be reduced substantially.
