It indicates, that in the United Kingdom, some supermarkets already have begun pilot programs to label foods that indicate the carbon signs which they produce. A producer of chipses is labeling some lines with its CO2 eq: each package of 34.5 grams that leaves the factory is responsible for 75 grams of CO2 eq. The Trust Coal, in London, it is working in a standard system so that the companies can follow to track CO2 eq of any product. Very interesting its question, on, how calculates the CO2 sign eq of its stomach? On the matter it comments: It is far from being simple. In order to begin, the amount of energy used from the farm to the possesor is due to analyze, to measure its contribution to the gas greenhouse.
Thus, a produced food using wind or solar energy will generate less emissions than those than were based on gas or coal. For the milky meat or products also the emissions of methane and nitrous oxide, two powerful gases with greenhouse effect are due to consider. The total of emissions of a food depends to a great extent from where it comes and from how it was transformed into his dinner from the raw material. This includes generated gases to work the Earth, sowing of cultures, by pesticides and fertilizers, the harvest and the transfer to the plants processors, like the electricity for cleaning, processing and packing of foods, and soon by the transport to the commerce. Finally, the clearing of forests for the pasturing or culture is due to consider. The calculations have become " endiabladamente complicados" , it indicated Astrid Scholz. It is added in the analysis that is considered that when is foods that have the potential major of terrestrial heating, the products with red meat are between the worse ones. The cattle young is responsible for 18% of the emissions greenhouse caused by the man: 9% of all the CO2, the 35 to 40% of the methane and 65% of nitrous oxide.
