A multi-criteria approach to evaluate the sustainability performances of wines: the Italian red wine case study.

The wine industry has faced two significant environmental problems in recent years: productivity is challenged by environmental trends such as global warming, and buyers are becoming more environmentally conscious. From an environmental standpoint, the food industry is one of the most impacting sectors and wine results as one of the most studied agri-food products in the scientific literature. In general, comprehensive studies that consider an application of set of indicators to evaluate the overall sustainability of wine sector are lacking in literature. This paper aims to carry out a sustainable assessment using different indicators for fifteen Italian red wines: Water Footprint (WF), Carbon Footprint (CF), Vineyard Indicator (VI), and Territory Indicator (TI). VI is an indicator of the vineyard's agronomic management's sustainability at plot level with values ranging from 0 (fully sustainable) to 1 (fully not sustainable), while TI covers the socio-economical aspects of sustainability. Considering system boundaries from cradle to grave, at 90% confidence interval, CF results ranged between 0.97 kg CO2 eq./functional unit and 1.97 kg CO2 eq./functional unit, with an average estimated at 1.47 kg CO2 eq./functional unit, while the WF of a 0.75 L bottle of wine from cradle to gate is 666.7 L/functional unit on average, out of which 86.75% is green, 1.92% is blue and 11.34% is grey water. Concerning the VI, at 90% confidence interval VI results were between 0.117 and 0.498 with an average estimated at 0.307. The results of the correlation analyses confirmed that each indicator is not statistically correlated with each other. Concerning the sub-indicators, a positive correlation has been found between the total CF and the sum of blue and grey WF. The application of a multi-criteria analysis for sustainability performances evaluation of the wine sector presented in this study can be used by wine companies' experts to better assess sustainability performances.

Benchmarking of carbon footprint data from the Italian wine sector: A comprehensive and extended analysis.

The interest in sustainability, within the wine sector, is growing simultaneously with the awareness of the environmental impacts on climate change generated by the sector itself. In this context, environmental methodologies need to be applied: Carbon Footprint of a Product (CFP) is a quantitative expression of Greenhouse Gases (GHGs) emissions that plays an influent role in emission management and evaluation of mitigation measures over the full life cycle of a product. Moreover, CFP application in the agri-food sector remains scarce due to complex, expensive, and difficult data collection. This paper aims to determine the main factors that contribute to the CFP of 33 Italian wines from 16 wineries and compare and evaluate the results obtained using all the inventory data or results obtained using a simplified model with fewer inputs. The results per Function Unit (0.75/ L of wine) have been obtained using a unique methodology. Considering system boundaries from cradle to grave, at 90% confidence interval, CFP results ranged between 0.899 kg CO2 eq./FU and 1.882 kg CO2 eq./FU. The study underlines that most of the impacts can be related to few inventory data, in fact the main contributors of GHGs emissions are: glass bottle (29%), electricity used in the winery stage (14%), transport and distribution of the final product (13%), heat used in the winery phase (9%) and fossil fuels used in vineyard (8%). The results can be helpful to support the development of a simplified CFP and to obtain a benchmark for the CFP of the Italian wine sector. Furthermore, the present study can help businesses, policy makers and consumers in making decisions that lead to a better environmental outcome.

Development and implementation of a qualitative framework for the sustainable management of wine companies.

A growing number of companies around the world have already adopted sustainable practices as the majority of consumers are increasingly concerned with environmental and health issues. Despite this, lack of knowledge in sustainability can represent a limit to a sustainable conversion of Italian wine companies. This paper focuses on the development and suitability assessment of TERRITORY, a qualitative framework that assists sustainable management of winery farms with respect to biodiversity, neighbouring land use, agrochemical use, soil management, water management, landscape, site selection, heritage-cultural and aesthetic aspects, product quality and safety, human resource management, health of employees, community and consumers, economic repercussion of structures and territories, resource depletion, procurement practices and traceability. 47 wine companies have adopted the framework and its suitability has been tested and validated in a ten years trial. The present work reports the results of TERRITORY framework adoption in a winemaking cooperative, a grape and wine producer and a bottling firm, that respectively performed 76%, 92%, 62% (where 100% is maximum implementation of sustainable practices), with lower adherence in water, landscape and human resources management. The framework has driven wine companies towards improvements implementation: most relevant deal with a more effective communication to local community and consumers about health and safety, protection of biodiversity (towards a deeper knowledge of its territorial features), territorial values enforcement and improved communication. From the results it emerges that the framework guides the structural transformation of wine farms towards sustainable production and management by assisting the wine producers in identifying emerging opportunities in wine sector, such as fostering network with local communities, defining better soil, and water management through a multi-actor approach. Furthermore, it has been adopted in addressing the selection of quantitative indicators to adopt and monitoring campaigns.
