Nothing says Cornwall more than a Cornish pasty, but have you ever considered the environmental impact it is having?
There are 120 million Cornish pasties made annually and according to researchers at the University of Exeter each one produces around 1.5-2kg of carbon – though their carbon footprint can be halved if the traditional beef filling is replaced with a vegan or vegetarian alternative.
The researchers made the finding using a new tool that measures the carbon footprint of Cornish pasties.
The Carbon and Low Impact Pasty (CLIP) tool measures the carbon emissions of the ingredients that make up a Cornish pasty as well as factoring in transportation, freezing and the energy and water used to make it.
