Carbon footprint in Austrian viticulture – Evaluation of the main polluters and possible solutions in entire the production chain

Abstract

This study examines the carbon footprint of Austrian viticulture, with a focus on grape suppliers and wine producers across different regions. The analysis highlights key contributors to emissions, including vineyard replanting, grape production, wine production, using the certification data “Sustainable Austria” from the years 2022 and 2023. The findings reveal regional differences in emissions, with Burgenland, Lower Austria, Styria, Vienna and Carinthia, particularly in grape production. Notably, emissions from vineyard replanting remained consistent across all operation sizes, while grape production and packaging showed significant variation. Larger wineries benefited from economies of scale, displaying lower emissions per unit compared to smaller wineries. However, emissions related to small units (glass bottles…) and packaging remain critical areas for improvement, contributing a substantial portion of the total carbon footprint. The study underscores the need for continued sustainability efforts, particularly in optimizing packaging practices and supporting smaller wineries in reducing their carbon footprint.

 

Empreinte carbone de la viticulture autrichienne – évaluation des principaux émetteurs et solutions possibles tout au long de la chaîne de production

La certification de durabilité “nachhaltig austria” (www.nachhaltigaustria.at ; www.sustainableaustria.com) est proposée depuis 10 ans dans une version en ligne pour les exploitations viticoles autrichiennes et, entre-temps, plus de 25% de la surface viticole autrichienne est certifiée. Depuis la récolte 2022, “nachhaltig austria” calcule automatiquement l’empreinte carbone de chaque domaine viticole, par hectare de vigne, par litre de vin en fût et par bouteille de 0,75 litre (Poelz, W. et Rosner, F.G. 2023).  Les publications de l’année dernière et de nombreuses présentations au niveau national et international ont déjà abordé des sujets tels que le rechargement des bouteilles en verre, les bouteilles en verre légères, les énergies renouvelables, … Etc. Ont été mis en lumière en ce qui concerne l’empreinte carbone. La présente publication compare les millésimes 2022 et 2023 et analyse les questions relatives aux différences entre les millésimes, les régions, les intrants utilisés tels que les quantités et les sources d’énergie, les bouteilles en verre et les emballages, la production de vin biologique versus standardisée, etc. Et discute des solutions possibles.  Ces données sur l’empreinte carbone autrichienne seront utilisées pour contribuer aux discussions internationales en cours sur les normes internationales harmonisées dans le cadre de l’OIV et d’autres plates-formes et initiatives.

Co2-fußabdruck im österreichischen weinbau – bewertung der hauptverursacher und mögliche lösungen entlang der produktionskette

Die nachhaltigkeitszertifizierung “nachhaltig austria” (www.nachhaltigaustria.at; www.sustainableaustria.com) wird seit 10 jahren in einer online-version für österreichische weinbaubetriebe angeboten und mittlerweile sind über 25% der österreichischen weinbaufläche zertifiziert. Seit der ernte 2022 berechnet “nachhaltig austria” automatisch den co2-fußabdruck für jedes weingut, pro hektar rebfläche, pro liter fasswein und pro 0,75-liter-flasche (Poelz, W. und Rosner, F.G. 2023).  In den veröffentlichungen des letzten jahres und in zahlreichen präsentationen auf nationaler und internationaler ebene wurden bereits themen wie die wiederbefüllung von glasflaschen, leichte glasflaschen, erneuerbare energien, … Usw. Im hinblick auf den co2-fußabdruck beleuchtet. Die vorliegende publikation vergleicht die jahrgänge 2022 und 2023 und analysiert fragen zu unterschieden zwischen jahrgängen, regionen, eingesetzten betriebsmitteln wie energiemengen und -quellen, glasflaschen und verpackungen, biologischer versus standardisierter weinproduktion etc. Und diskutiert lösungsmöglichkeiten.  Diese österreichischen co2-fußabdruckdaten werden als beitrag zur laufenden internationalen diskussion über harmonisierte internationale standards im rahmen der oiv und anderer plattformen und initiativen verwendet.

A population genetic study of Vitis vinifera L. subsp. sylvestris Gmelin based on 3.000 individuals from 20 countries

Until the 19th century, the wild form of cultivated grapevines (vitis vinifera l. subsp. sylvestris gmelin, v. sylvestris) was ubiquitous in many european and west asian regions. However, many factors like deforestation, the intensification of agriculture, or the introduction of several pests and pathogens decimated its presence in these growing sites, and natural populations are now mostly restricted to river-bank forests and creeks with specific soil and climate conditions. in fact, v. sylvestris is now considered an endangered subspecies that is protected by law in many european countries to prevent its loss.

Generation of radicals in wine by cavitation and study of their interaction with metals, phenols and carboxylic acids

High-power ultrasounds have been related to an accelerated aging of wines, an effect that has been associated to the formation of radical species caused by the cavitation phenomenon [1]. This phenomenon consists of the formation of bubbles in the liquid medium that, when they collapse, cause high-pressure hot spots and temperatures of up to 4800 k [2], notably increasing the reactivity in the medium.

Vine selection in France: An assessment after more than 60 years of work

It was at the end of the second world war that professor Branas laid the foundations of french vine selection. He was also behind the creation of domaine de vassal (1949) and antav (1962), which were to become the bridgeheads of the french strategy for the conservation, selection and multiplication of viticultural diversity. Initially based on visually virus-symptom-free massal selections, with the main aim of providing healthy, clearly-identified plant material, the process evolved as knowledge gained towards clonal selection.

Evaluation of the efficiency of dialysis membranes in the wine dealcoholization process

The global wine production is continuously evolving to meet the new demands and preferences of consumers. in this evolving scenario, it’s important to determine which trends will be short-lived and which will remain over time. The promotion of healthier habits has encouraged consumers to try to find alternatives with low or no alcohol content. The challenge for the industry is to produce an alcohol-free wine that retains the familiar aromas and mouthfeel of traditional wine but without alcohol. Ethanol is the most abundant compound in wine, excluding water.

Determination of steviol glycosides in wine by HPLC

The SCL laboratory in Bordeaux is one of the two official control laboratories for wine and wine products in france, under the authority of the ministry of finance and two of its general directorates: the DGCCRF (directorate general for competition, consumer affairs and fraud control) and the DGDDI (directorate general of customs and excise duties). In this capacity, it verifies the regulatory compliance of wines and investigates any possible falsifications or fraud. Steviol glycosides are natural sweeteners that are not authorized as additives in wine.
