CARBON BALANCE®: FROM THE VINE TO THE BOTTLE

The climate is an important component for « terroirs ». Since 1898, the Swedish scientist Arrhenius had envisaged global warming due to the combustion of fossil fuels with the aim to fight against the recession of the glaciers. If a debate was established in 1975 about the contribution of man, the scientific community of the Intergovernmental Panel on Climate Change (IPCC) has since been able to show a close link between global warming and the greenhouse effect. In the future, the implication of these climatic modifications will not be without consequences on viticulture. Beyond the reflections and studies on adaptation routes for viticultural and oenological techniques in response to this evolution, the industry must limit its impacts on the greenhouse effect. In the first part, the mechanisms of the greenhouse effect and the issues of climate change will be presented. A second part will focus on the quantification of the greenhouse gas emissions in several French exploitations by the Carbon Balance® method.
