14 Jul 2021 --- As part of its VisionDairy Charter for sustainably sourced milk, chocolate giant Barry Callebaut has launched a pilot study that quantifies CO2 emission reduction in dairy cattle as a result of feed additives. This is in collaboration with plant-based feed additive producer Agolin and environmental certifier Gold Standard.The use of animal feed additives – like Agolin’s – is widely recognized to reduce methane emissions in dairy cattle. However, in the past, there was no way to credibly verify this and thus assess the actual level of CO2 reduction within our supply chain.
