If everyone in the UK abstained from eating meat for one day a week, this would save greenhouse gas emissions
equivalent to 13 megatonnes of CO2(Mt CO2eq). This would result in greater carbon savings than taking 5 million cars off the road in
the UK (10 Mt CO2 eq).
If everyone in the UK did not eat meat for two days a week, they would save 26 Mt CO2 eq of greenhouse gas emissions. This would save the equivalent of almost 73 million return flights from London to Ibiza.
If all British people abstained from eating meat three days a week, they would save almost 40 Mt CO2 eq of greenhouse gas emissions. This would have the same positive effect on reducing greenhouse gas emissions as replacing all household appliances, such as fridges, freezers, dishwashers and washing machines, with energy efficient ones, insulating walls and installing double-glazing, energy efficient boilers and thermostats (38 Mt CO2 eq).
