Purchasing Routes as Part of the Consumer Carbon Footprints (CCF)
What part does the final consumer play in the effect of food processing chains on climatic change?

The influence of the consumer on climatic changes caused by complete processing chains the Consumer Carbon Footprint (CCF) may be larger than has been thought. This is a pilot study on the contribution of the consumer to the CCF and is based on three approaches: evaluation of macro-statistical data, diary studies and inquiries at point of sale (PoS). The present results show that the CCF can differ greatly between individuals.
The evaluation of macro-statistical data gives a CCF-value of 280 g CO2/kg. The diary study provides an average CCF-value of 293 g CO2/kg. The inquiry at the PoS clearly shows the influence of the means of transport. As a large proportion of the subjects were pedestrians, or used bicycles or public transport, the average CCF was only 124 g CO2/kg. The positive effect of a CO2-neutral transportation is obvious. The evaluation also shows that an urban environment with a good infrastructure has a positive effect. Shopping can generally made more favourable to the environment by deliberate planning. There remain many open questions in this area of research and these must be addressed by studying representative samples with optimized methods. Crucial issues include the influence of household size on the CCF and the differences between urban and rural areas.
