In accordance with the Scottish Government’s Programme for Government, Aberdeen City Council is looking at options for a Low Emission Zone in Aberdeen.
Currently, 8 options have been identified for public and stakeholder consultation and detailed traffic and air quality modelling.
Public and stakeholder engagement on the options took place during September and October 2020 and the findings of this are currently being analysed.
The outcomes of this engagement exercise will be combined with the findings of the modelling work to help determine a preferred option for a LEZ in Aberdeen.
Further information on LEZs can be found within the FAQs at the bottom of the page.
The Interim Stage 2 Low Emission Framework Summary Report (a report on the option appraisal process to date) can be downloaded from the link below. A Non-Technical Summary Report, showing the various LEZ options under consideration, can also be downloaded.
Why a Low Emission Zone (LEZ) is needed in Aberdeen
A LEZ is a defined area where the only vehicles that can be driven without penalty are those which meet set standards for exhaust emissions.
Why is Aberdeen introducing a LEZ now?
|The Scottish Government committed to the introduction of LEZs in Scotland’s four biggest cities (Aberdeen, Dundee, Edinburgh and Glasgow). The Transport (Scotland) Act provides the legislation to make this happen, and the accompanying Regulations and Guidance due to be published by the end of 2020 will provide standards to ensure nationally consistent LEZs.|
Why is air pollution a problem?
The higher the levels of pollution and the more time people spend in polluted air, the worse the effects on health can be. Some people notice its effects immediately, but long-term exposure to air pollution can lead to or exacerbate conditions including heart disease, strokes, asthma, lung cancer and damage to other internal organs. The very young and the very old, as well as those with health problems, are particularly affected.
|What causes air pollution?||Air pollution is caused by many factors, some natural and some man-made. But the main source of air pollution in Aberdeen (and most UK cities) is road traffic. Nitrogen dioxide (NO2) is the main air pollutant of concern in Aberdeen. In some parts of the city where pollution levels are high, 80% of the NO2 pollution comes from road traffic.|
|Is air pollution in Aberdeen very bad?||Air quality is good in most places in Aberdeen, but there are places where monitoring indicates pollution is above, or is close to, set maximum levels.|
|Who sets limits for air pollution?||Maximum levels of air pollution are set by European and Scottish laws. For NO2 the annual average level should not be more than 40 μg/m3|
|Where is air pollution in Aberdeen worst?||Aberdeen has declared three Air Quality Management Areas in which pollution exceeds set objective levels:
|What types of traffic cause most pollution?||The proportion of pollution that comes from different types of traffic varies by location. For example, on Union Street which is a major bus corridor, 48% of NO2 pollution is caused by buses. But on Market Street, almost half of NO2 pollution is caused by lorries and vans, 34% by cars and 19% by buses.|
|By how much will a LEZ reduce pollution?||This depends on the area that the LEZ would cover and which vehicles are included in it. Technical work shows that:
• a LEZ which only includes buses is not enough to achieve set pollution levels everywhere in Aberdeen;
• a LEZ which includes all vehicle types lowers pollution levels significantly but pollution levels in some areas remain higher than is legal;
• complementary traffic management will be required to improve air quality in all locations.
How will a LEZ in Aberdeen work?
|What area will Aberdeen’s LEZ cover?||This has not yet been decided. Aberdeen City Council will decide on the LEZ area based on technical analysis and feedback from public and stakeholder consultation. However initial technical analysis concluded the LEZ will focus on the city centre area.|
|When would Aberdeen’s LEZ operate?||This has not been formally decided (and will be determined by regulations) but it is expected to be in effect 24 hours per day, 7 days per week.|
|When will the LEZ come into force?||
An indicative timeframe from the Scottish Government aims to introduce LEZs by May 2022.
The formal declaration of Aberdeen’s LEZ will be followed by a grace period for enforcement of the LEZ restrictions so that people and businesses have time (if necessary) to change their vehicles or their journey patterns.
Aberdeen City Council has not yet decided how long any grace period will be, but current guidance states the grace period must:
|Will I still be able to drive into the LEZ area?||This depends on your vehicle and the decisions regarding which vehicles will be affected. Aberdeen City Council will decide on the vehicle types, based on technical analysis and consultation feedback. But you might be affected if you drive a:
|How can I check whether my vehicle will be affected?||The Scottish Government has developed an online vehicle checker to enable drivers to check whether their vehicles are compliant with LEZ restrictions, based on the date of registration.|
|Isn’t banning buses a good idea to reduce pollution?||No. Although buses do cause pollution, they are many people’s only way to get to or around Aberdeen and are typically more efficient per person than cars. Emissions have been falling as operators bring in new, cleaner buses (including buses fuelled by hydrogen). Aberdeen City Council considers it essential that the city has a good bus network.|
|How will the LEZ be enforced?||ANPR (Automatic Number Plate Recognition) cameras will identify the number plate of every passing vehicle and check them against a database of compliant vehicles. The owner of any non-compliant vehicle driven within the zone would be issued with a penalty charge notice.|
|What will the penalty charge be?||The penalty rates will be set at a national level by the regulations. No details on the penalty levels are known yet but it is expected that different levels will exist for different classes of vehicles and for repeated infringements.|
|How will the zone boundary be marked?||Clear road signs will mark the boundary of the zone. Drivers of non-compliant vehicles will be able to choose to drive around the zone rather than into it or use alternative means of transport if they wish to avoid incurring a penalty.|
|Will anyone be exempt from the regulations?||Anyone driving a compliant vehicle will be exempt. Vehicles belonging to residents of the zone may be exempted for a longer minimum grace period, as described above, but will not be permanently exempted.
Other exemptions (for disabled drivers, for example) are being considered at a national level and will be set by the regulations.
|Is support available to help me replace a non-compliant vehicle?||
Support is available for households, businesses with 10 or fewer full-time employees and sole traders within a 20km radius of the planned low emission zones in Scotland. The Low Emission Zone Support Fund will financially support eligible households on specific means-tested benefits, as well as businesses with 10 or fewer full-time employees and sole traders, with a grant to move away from older petrol and diesel vehicles. Further information is available from the Energy Saving Trust.
Will the LEZ be effective?
|How will we know if the LEZ is being effective?||Aberdeen City Council will continue to monitor air pollution levels at locations across the city, both inside and outside the LEZ boundary, and results will continue to be published by the Council in its Air Quality Annual Progress Report.
The Council will also assess whether the LEZ is meeting its objectives and will amend or remove the LEZ as necessary.
|Will the LEZ push traffic and pollution onto other streets?||Aberdeen City Council wishes to avoid this risk if possible. Detailed assessments of traffic routes are being made, and the Council will consider the findings of this before taking any final decision.|
