The Low Emission Zone Annual Report (LEZAR) published today (February 2) outlines the progress of Edinburgh’s scheme in its first financial year since enforcement began in June 2024.

After meeting the scheme’s operating costs, any surplus LEZ income must be used towards the scheme’s wider objectives.

The Transport and Environment Committee agreed in August 2024 that surplus income would be used to fund citywide Council projects which contribute to air quality and/or climate change emission reduction. Committee also agreed that special consideration should be made to projects in areas bordering the LEZ.

Some of the projects which funding is being allocated to include:

• Supporting the delivery of the city’s 7-7-7 bus lane trial
• Delivering traffic sensors to improve network data intelligence and monitoring
• Research to support businesses on air quality issues
• Engagement activities with local schools on air pollution and climate change
• Measures to tackle engine idling

A full list is available in the LEZAR.

In our most recent Air Quality Annual Progress Report (APR), we’ve also seen a consistent downward trend in Nitrogen Dioxide (NO₂) concentrations across both city centre and residential sites.

The Scottish Environmental Protection Agency (SEPA) is preparing a separate report with a nationally updated model for the LEZ, which will include updated traffic and air quality information for Edinburgh.

The Institute of Occupational Medicine (IOM) also published a study indicating that active travel and public transport use increased within the LEZ during the first six months after LEZ enforcement. Footfall data gathered from 2021 to 2025 shows that walking as a mode of travel in the city centre has increased.

Transport and Environment Convener, Councillor Stephen Jenkinson said:

“This report underlines the real progress that’s been made since LEZ enforcement began. I have no doubt that this new revenue will unlock many new and exciting projects which will benefit residents across the city.

“As Scotland’s capital city, we have a core responsibility to combat the climate and nature emergencies. Fundamentally though, the LEZ is about making our city healthier for everyone. Multiple studies show that even low levels of pollution can have an impact on our health, with road traffic being one of the main sources of harmful emissions. We’ll continue to encourage people to use active travel and public transport wherever possible, whilst reducing their car use and considering lower polluting vehicles. Our commitment to this can be seen in new developments like the trial cycle hire scheme along with projects under our City Mobility Plan, giving our residents greater choice and creating a better city for us all.

“The latest air quality data, average decrease in PCNs, and positive shift towards greater use of active travel and public transport, shows clearly that we’re headed in the right direction.

“The LEZ remains an important tool to help us achieve our ambitious climate goals, including net zero emissions by 2030.”
