Actually, Mr. Chair, the way the European Union approached it in 2002 was to issue a directive on the labelling of caffeine-containing beverages that exempted products with “coffee” or “tea” in the name from this quantitative labelling.
This is actually where consumers run into the problem. They may have very accurate information about the caffeine content in energy drinks, or in Europe with products containing more than 150 milligrams of caffeine per litre, but when they buy these products, they do not have the information on coffee and tea at hand, which I agree won't be easy.
This is because coffee, for example, has a caffeine content that depends a lot on the method of preparation and how you make your coffee. When you go to the big coffee chains, for example, the production is more or less standardized, and they also will not have this information. I think that in order to see how much caffeine you get from different sources over the day, this information should be available to consumers.
