According to the Telegraph, the supermarket giant is undertaking tests on livestock at its Dairy Centre of Excellence in Liverpool as part of a project to help reduce its carbon footprint.

The news organisation says that each cow is fitted with a microphone, attached to a special collar, which picks up sounds from their stomachs.

The information is used to work out how effectively each animal is digesting its food, which determines how much methane gas they emit.

Research suggests that methane emissions from cattle accounts for three quarters of the entire carbon footprint produced by milk production.
