O plano de sustentabilidade dos vinhos do Alentejo (PSVA) é um programa de desenvolvimento da produção vitivinícola na região do Alentejo promovido pela comissão dos vinhos regionais do Alentejo (CVRA), com o objetivo de mitigar perdas energéticas e financeiras no setor vitivinícola alentejano, tornando-o ao mesmo tempo apto para novos mercados. O sector está cada vez mais competitivo, existindo a necessidade de adaptação, por parte do AE (Agente Económico) ao mercado e a fatores externos que possam colocar a empresa em stress, e de constante evolução dos métodos de produção do vinho, para que sejam mais sustentáveis. A gestão sustentável de energia é um dos aspetos desta abordagem, em particular na adega. No âmbito do plano de sustentabilidade de vinhos do Alentejo e em parceria com a CVRA, procedeu-se à auditoria de duas adegas da região alentejana. As auditorias avaliaram os consumos de energia e água de cada uma das adegas, permitindo avaliar o seu desempenho, através da determinação de indicadores ambientais como o consumo específico de energia e água por unidade de vinho produzido. Os resultados permitem identificar um conjunto de possíveis melhorias, que com um investimento relativamente reduzido, podem contribuir significativamente para o melhor do desempenho das adegas. Estes resultados são ainda comparados entre si e com os de auditorias semelhantes realizadas em outras adegas da região alentejana. Verifica-se que as adegas estudadas apresentam desempenhos energéticos semelhantes, com exceção de uma adega que se destaca positivamente das outras, apresentando um melhor rácio consumo/produção. A comparação permite ainda identificar um conjunto de boas práticas que podem recomendar alterações relevantes nos procedimentos e equipamentos para a produção vitivinícola da região, contribuindo para reforçar o caracter sustentável do vinho do Alentejo, reduzindo a sua pegada ecológica e os custos de produção enquanto, simultaneamente, contribuindo para a abertura de novos mercados e valorização do produto.
The Alentejo wine sustainability plan (PSVA) is a wine production development program in the Alentejo region promoted by the committee of regional Alentejo wine to mitigate energy and financial losses in the Alentejo wine sector, making it at the same time suitable for new markets. The sector is increasingly competitive, which points for a need of adaptation, by the economic agents (EA) to the market and to external factors that may put the company in stress, and a constant evolution in the wine production methods, to become more sustainable. Sustainable management of energy is one the aspects of this approach, particularly in the cellar. Under the PSVA goals, two audits were conducted at two wineries in the Alentejo region. The audits evaluated the energy and water consumption of each of the wineries to evaluate its performance, by determining environmental indicators such as the specific consumption of energy and water per unit wine produced. The results allowed to identify several possible improvements that with a relatively small investment, can significantly contribute to the better performance of the wineries. These results are still compared with each other and with similar audits in other wineries of the Alentejo region. It appears that the wineries studied have similar energy performance, except for a winery that stands out positively of the others, with a better consumption/production ratio. The comparison also allows to identify a set of best practices that can recommend significant changes in the procedures and equipment for wine production in the region, helping to strengthen the sustainable character of the Alentejo wine, reducing its environmental footprint and production costs while simultaneously contributing to the opening of new markets and appreciation of the product.
