Global wine producers emitted around 96 million tonnes of CO2 in 2021, according to an analysis by the global US consultancy Kearney. Compared to 2018, the value has dropped minimally, at that time it was around 97 million tonnes. However, this decrease is justified with the slightly reduced production, because the CO2 emissions per litre actually increased in this period - from 3.5 to 3.7 kilograms.
"Wine and spirits producers have seen a relative increase in their emissions, while beer, cider and soft drinks producers have been the most efficient in reducing their carbon footprint. They reduced their emissions by eight to nine per cent since 2018," write those responsible for the study.
According to the study, raw materials such as vine, plant and soil processing were responsible for a total of 35 per cent of emissions, packaging for 23 per cent, operations including equipment and storage for 11 per cent, and transport for 13 per cent.
