People can log on to the South Yorkshire Carbon Footprint Calculator website to work out their carbon footprint and calculate how much money they have saved on their energy bills.

Residents will also be able to make a pledge to say how they will be more energy efficient.

They will get an email a few months later to confirm they have met their pledge and their carbon footprint will be recalculated.

Data will be stored and used to show how each local authority in the region is actively trying to improve its carbon emissions.

Councillor Mark Thompson, Doncaster Council's cabinet member for environment, said: "We can all make immense savings on energy bills by making simple, straightforward adjustments to our day-to-day activities, while reducing our carbon footprint to a sustainable level."
