Abstract:	As a matter of fact the interest in understanding the impact of anthropologic action on environment increased over the past two decades. Pooled under the term sustainability any kind of process is nowadays evaluated against the background of used resources such as for example water, energy, pollution or manpower. Creating a detailed examination of sustainability, one is faced with the challenge of where to draw the system boundaries. Driven by the wish of going into detail of one special process those examinations get more and more individualized depending on the circumstances of production on site. This individualisation makes the examinations labour intensive and hard to use when comparing among each other. Transferred to grape harvest, the regie time such as driving to the vineyard and back into the winery, manoeuvres on site as well as which motor pool and mode of grape transportation is used, has a crucial influence on the final result of the examination while there is no grape harvested jet. For an easier way of comparing different modes of harvest on differently shaped vineyards it is proposed to separate this time from the process time, the time of actually harvesting grapes. As the harvest is a dynamic process the time implicit a certain distance. As functional unit the covered distance in meter to harvest a defined grape quantity [m / kg] can be applied. This unit depends on the variables row length and crop yield only and can even be applied to grape production processes. Different modes of action in the vineyard can be compared among each other more easily. For a more detailed examination the covered distance during both, regie and process time, can be summed up and transformed into energy according to the used motor pool and subsequently expressed in CO2- equivalents. This approach was used to find the best matching field geometry for a low energy consuming grape harvest, evaluating harvesting by hand or machine. The model shows the expected diminishing marginal utility of row length at a given crop yield or vice versa the minimum crop yield for a given row length concerning minimizing the driven meters per kilogram of grapes.
