The London Borough of Lambeth are proposing to implement additional permit parking changes for diesel cars that do not meet the Euro 6 standard – that means all of them that are more than a few years old. The additional charge will be £40 per year.

We have sent in objections simply on the grounds that this is a political gesture that will have minimal impact on air pollution in the borough, or is motivated by a desire to raise revenue for the Council. A similar calculation recently for Merton showed that the impact might be a reduction of 0.4% in overall NOX emissions which is too small to be measurable in practice. In addition, as clearly there will be additional revenue raised for council budgets, without any offsetting reduction in charges for other vehicles, this change is effectively a revenue raising measure and hence illegal. It has been established by more than one legal precedent that permit parking charges cannot be used to raise revenue but can only cover administration and enforcement costs.
