Britain’s biggest dairy producer is creating a huge climate database in a bid to become the greenest on the planet.
Arla, owned by 2,300 UK farmers and thousands in Europe, wants to become carbon neutral by 2050.
The co-operative’s farmers will generate an individual eco-score by inputting information including the size of herds and fuel usage.
Experts will then visit each one to create a bespoke plan for how they can slash pollution levels.
The group produces 14 billion litres of milk a year and claims its farmers already emit less than half the industry’s global average CO2.
Senior director Graham Wilkin-son said: “We want to ensure dairy has a sustainable future.”

Boss Ash Amirahmadi added: “Whilst there is a lot of negative comment about the impact of food production, farmers are, in reality, the caretakers of the countryside.”
It follows Arla’s move to scrap use-by labels this year to stop people binning perfectly good milk.
Shoppers will be urged to use the sniff test to check if milk is off.
