Thousands more children are walking to school following a campaign encouraging parents to leave their cars at home.
Use of cars has been cut by more than 10 per cent in the past five years as schools have received funding to invest in cycle storage, lockers and pedestrian shelters where parents can wait when collecting their children.
Every school in Norfolk, including private schools, has a travel plan setting out how they will increase sustainable travel and tackle car use and congestion.
Hempnall Primary in Norwich has cut car use by almost a quarter: 68 per cent of its pupils now walk to school.
Josie Barnett, senior travel-plan officer at Norfolk County Council, said: "Some of the results have been spectacular, but the overall success of the school travel plan initiative reflects the many small but significant changes made by many school communities.
"With the risks of climate change and obesity threatening the quality of our everyday lives, the importance of the school journey as a foundation for a healthy and sustainable lifestyle is more important than ever," she said. DM.
