Scientists are using the findings from a new study, which revealed the effectiveness of constructed wetlands and microalgae to cut carbon emissions in wineries, as a “call to action” to ensure “the preservation of our planet for future generations”. Wineries should be utilising constructed wetlands and microalgae, known as Phycosol, to cut significant carbon emissions, a new study published in Nature has found. The study, named ‘Eco-innovation minimises the carbon footprint of wine production’, claims that “most studies often overlooked the resources in farming practices, biogenic emissions, and wastewaters” in the overall reduction of winery carbon footprint. As such, the researchers have set out to demonstrate that innovations, including constructed wetlands and the use of Phycosol, utilise an often overlooked resource loop to significantly reduce CO2 emissions. “In a world that is striving to achieve net-zero emissions and address pressing sustainability concerns, whether it be through seaweed farming or wastewater innovations, the wine industry adaptations are particularly salient,” the researchers said. According to data cited by the study, the main contributors to carbon footprint are viticulture (27%), winemaking (23%), and wine bottling (50%). However, the study also claimed that traditional assessment approaches often underestimate the total greenhouse gas emissions associated with winemaking. The discrepancy often arises from overlooking elements including CO2 from fermentation, wastewater and soil carbon fluxes, the study claimed. “A more holistic approach to assessing the environmental impact of wineries is necessary,” its authors argued. They proposed the use of constructed wetlands and Phycosol, which can transform wastewater
