Chocolate Maker to Cut Cow's Greenhouse Gas Emissions
Whether it's using garlic to fight cow's methane emissions, or an increase in chopped hay/straw feed reducing greenhouse gases, cow belches are an urgent problem that needs addressing. In fact, the problem is so severe that the chocolate maker Cadbury's estimates methane emissions from cows are responsible for a whopping 60% of their Dairy Milk chocolate bars' greenhouse gas footprint. Now, according to the Guardian, they are working with farmers to tackle their dairy-related carbon/methane footprint:
Cadbury has sent the farmers a guide for low carbon dairy farming, which includes advice on changing the diet of the cows to cut their eructations. Farmed ruminant animals are thought to be responsible for up to a quarter of "man-made" methane emissions worldwide though, contrary to common belief, most gas emerges from their front, not rear ends. Studies show that the production of one litre of milk produces the equivalent of 900g of CO2. More than half of this is down to methane. The average cow emits between 80kg and 120kg of methane a year, equivalent to the annual carbon emissions from an average family car.
Ian Walsh, Cadbury's global head of environment, said the company was looking to reduce the environmental impact of its supply chain. "We are committed to tackling climate change and we rely on scientific research to inform the actions we take." The company worked with the Carbon Trust to work out the life cycle emissions of the chocolate.
Great to see companies like Cadbury's are providing both incentives and support to farmers to take this issue seriously.
