Terra dei Re was the first company in the world to obtain the Friend of the Earth certification in the wine sector. Aglianico del Vulture Nocte was the first certified sustainable wine. In the field of viticulture, the definition "Sustainability" can be identified with the conservation of environmental and varietal conditions. Being sustainable means preserving what has been handed down to us and what nature has given us. Sustainability is closely linked to biodiversity or to the quantity of flora and fauna present in a given environment. Our primary goal is not to alter environmental conditions and promote natural balances. We have therefore put in place all the necessary actions so as not to interfere with what nature has created. The project has brought our company to the forefront in the production of sustainable wines. Let’s start from the idea that every time a vehicle is started, CO2 is released into the atmosphere. To begin with, staff need training, to know what to do to pollute less. We have collected the data necessary to identify the emissions flows by analyzing the life cycle of our wines. Noting the energy consumption in the vineyard, knowing the impact of transport in terms of pollution in and out, knowing precisely the consumption in the cellar allows us to intervene where there are excesses of energy consumption. We produce electricity through photovoltaic systems, we collect rainwater that we use in agriculture, we have reduced energy consumption and practised precision farming. After about ten years of study and data collection we determined the environmental impact of each of our wine bottles. After this determination, we have put the corrective measures in place, reducing CO2 emissions into the atmosphere by more than 30%. We can verify that the production of our wines has a very low environmental impact.
