NHS Lothian, and Asthma + Lung UK have praised the benefits of the LEZ, following a year of enforcement.
Experts at the NHS and a leading charity have highlighted the ongoing impact of the LEZ enforcement on air quality and health. In addition, the new rules have incentivised active travel and greater use of public transport.
A LEZ was introduced in Edinburgh on 31 May 2022, along with LEZs in Glasgow, Aberdeen, and Dundee, restricting the most polluting vehicles and benefiting everyone’s health. Edinburgh began enforcement alongside Aberdeen on June 1, 2024. Dundee began enforcement on May 30, 2024, and Glasgow on June 1, 2023.
With Clean Air Day (19 June) just a few weeks away too this one-year anniversary is a timely reminder of the importance of the LEZ here in Edinburgh and beyond.
In recent years air quality in Edinburgh has improved, with our monitoring data showing reduced pollution levels, and people getting ready for the LEZ may have contributed to this.
Over the last year, the average amount of Penalty Charge Notices (PCNs) issued for non-compliant vehicles entering the zone has been decreasing steadily.
Between June 2024 and January 2025 alone the total number decreased by 56%. There is also evidence of lower numbers of second contraventions. The vast majority of vehicles entering the LEZ are compliant, over 95%. Around 3% of vehicles entering the LEZ are exempted classed.
The Institute of Occupational Medicine (IOM) has also published a study indicating that active travel and public transport use increased within the LEZ during the first six months after LEZ enforcement.
The first annual report on LEZ operation is expected to be presented to the Transport and Environment Committee later this year, including air quality trends and how the scheme contributes to our carbon reduction targets, as well as operational matters such as the number of PCNs issued, costs of maintaining and operating the scheme, gross and net revenue and other key issues.
The Council is working with the Scottish Environmental Protection Agency (SEPA) on data collection and analysis of the LEZ and will present a report in the Scottish Parliament that will help inform the national picture of LEZ impact.
Transport and Environment Convener, Councillor Stephen Jenkinson:
I’m proud that alongside Aberdeen, Dundee, and Glasgow we took the bold step of implementing and enforcing a LEZ. We’re sending a clear message that our major cities are united in pursuing a better future for all. Fundamentally, the LEZs are about making our cities healthier for everyone.
As Scotland’s capital city, we have a duty to lead on the response to the climate and nature emergencies which will define our country for generations to come. Multiple studies show that even low levels of pollution can have an impact on our health. Road traffic is one of the main sources of harmful emissions that are damaging people’s health and contributing to climate change, so we have a real responsibility to tackle this.
The average decrease in PCNs here in Edinburgh show that people are getting used to the LEZ and modifying their habits accordingly. It’s also encouraging to see studies showing a positive shift towards greater use of active travel and public transport.
I look forward to seeing the annual report when it is considered by Committee.
The LEZ is one important tool to help us achieve our ambitious climate goals, including net zero emissions by 2030.
Flora Ogilvie, Consultant in Public Health, NHS Lothian said:
It’s great to know that the LEZ enforcement has been in place for a year, helping to improve air quality in the city and protect the health of our most vulnerable residents. Improving air quality and reducing traffic levels are also an important way of encouraging more people to travel by walking, wheeling, cycling and public transport.
Travelling sustainably can help improve individual physical activity levels and mental wellbeing, as well as supporting better environmental health for the whole population and planet.
Joseph Carter, Head of Asthma + Lung UK Scotland said:
We are pleased that Edinburgh along with Dundee and Aberdeen made the bold move a year ago to ban the most polluting cars from their city and it is a step in the right direction to help improve the air that we all breathe.
With air pollution cutting short thousands of lives a year, we want to see our cities become far healthier places, where people can walk and cycle and not be forced to breathe in dirty air.
With 1 in 5 people in Scotland developing a lung condition like asthma and chronic obstructive pulmonary disease (COPD) in their lifetime, for them, air pollution can trigger life-threatening asthma attacks and flare-ups.
Children are more susceptible to air pollution as their lungs are still growing, and they also breathe faster than adults. As they grow, toxic air can stunt the growth of their lungs, making them less resilient into adulthood and placing them at greater risk of lung disease in the future.
Further Information:
77% of all PCNs in the last year were served to light passenger vehicles (private cars) and 21% to light goods vehicles (panel vans) with the remaining 2% being divided among the other classes of vehicle. 62.4% of PCNs are paid within 14 days at the discounted rate.
The penalty charge structure for all of Scotland’s LEZs is set by the Scottish Government.
We publish regular updates on PCN figures on our website.
Income from the LEZ will be used in the first instance to pay for the operation and maintenance of the scheme. Any surplus income will be contributed towards Council projects which contribute towards the wider goals of the LEZ, particularly improving air quality and climate change emission reduction.
All LEZ monitoring and evaluation information will be made available on our webpages.
Air pollution is associated with between 29,000 and 43,000 deaths a year in the UK. The World Health Organization and the UK Government both recognise that air pollution is the largest environmental threat to our health.
Another key development is that the Low Emission Zone Support Fund has now resumed and is open to new applications. This is funded by Transport Scotland and administered by the Energy Saving Trust.
There are separate funds available for households, businesses and retrofitting vehicles. All eligibility criteria and application details can be found on the Energy Saving Trust website
