Carbon Footprint: Vernaccia di San Gimignano is born naturally “clean”

The first phase of the project assigned by Consorzio della Denominazione San Gimignano to Indaco2, a spin-off company of the University of Siena, to discover how much CO2 is currently emitted during the production of a bottle of Vernaccia di San Gimignano, considering the entire chain, from cultivation in the vineyard to vinification in the cellar and the bottling of the finished wine, has been completed. The Carbon Footprint is the indicator chosen to determine the potential impacts of the life cycle and to identify the policies for the mitigation and compensation of these impacts.
The response has been more than positive, particularly considering that the study offers a picture of the real situation, before the implementation of any corrections to the production cycle: the average value of the emissions generated for the production of a bottle of Vernaccia di San Gimignano is 0.90 kg of CO2 equivalent, an excellent result, well below the average obtained from a sample of white wines monitored in Italy.
The project involved four pilot estates, selected throughout the area as representative of the San Gimignano production situation: the largest one, in terms of the extension of area occupied by vineyards and production, and other three of small and medium dimensions, two of which use organic farming methods.
The tests carried out by the Indaco2 team showed, in detail, the effects of the various production phases, therefore allowing the definite identification of a series of possible solutions to further reduce the impacts of production.
The project pursued by Consorzio della Denominazione San Gimignano represents the initial phase of a journey that leads towards production with zero emissions. The current state of production of Vernaccia di San Gimignano has been defined and a series of information has been collected to transfer to the producers.
This is where the responsible winegrowing of the future starts, this being the main aim of Consorzio della Denominazione San Gimignano, which has taken up the challenge of becoming an active part and a leader in a journey of sustainable growth of the entire system, as explained by the President of the Consorzio, Letizia Cesani:
“The study of the life cycle of a bottle of wine is essential in order to trace the environmental profile of an estate based on real scientific facts, starting from which it is possible to define, in an equally scientific way, the technological and operational methods capable of reducing the emissions of carbon during the various production phases, with results in terms of energy saving that will also be economically positive in the short/medium term.
Environmental respect and enhancement of the value of the production of Vernaccia di San Gimignano are not and will never be antagonists, but two connected concepts, each of which is accomplished thanks to the accomplishment of the other”.
