Liverpool's Clean Air Plan

The UK is subject to EU laws requiring that we meet certain legal limits for a number of air pollutants. Levels of air pollution are above these limits in many cities within the EU and around the UK, including some specific areas in Liverpool. The UK government is working to bring the levels of pollution to below EU limit values as quickly as possible. Nitrogen Dioxide is the only pollutant in Liverpool that is above the legal level in some areas of the city.

On 5th October 2018, the Mayor of Liverpool Councillor Joe Anderson received a ministerial direction from the government requiring that Liverpool City Council produce a Clean Air Plan (CAP). This plan will need to explain how the council will achieve legal levels for Nitrogen Dioxide as quickly as possible. The legal deadline for the council to complete the plan is 31st October 2019.

Stages leading to the plan's completion

There are several important stages to be met to allow the CAP to be completed, each with clear results and deadlines.

Stage one - the Strategic Outline Case

The first stage is to write a Strategic Outline Case (SOC). This was submitted for approval to air quality experts in UK government, known as the Joint Air Quality Unit (JAQU) on 31st January 2019. The SOC includes a long list of options that we can take to improve air quality in Liverpool and compares these options against criteria set by the UK government. This will result in a short list of options that the council could think about in more detail.

Stage two - the Initial Evidence Submission

The second stage of the CAP is the Initial Evidence Submission (IES) to JAQU by the end of June 2019. The IES contains the results of computer modelling of the road traffic and air quality across Liverpool. The modelling will find the roads that are currently exceeding legal levels across the city and are predicted to exceed these levels in the future.

Stage three - the Outline Business Case

Following the approval of the IES by JAQU, there will be further computer modelling. The short listed options identified in the first stage, will be put into the computer model to see which options will help Liverpool meet the legal levels for Nitrogen Dioxide. The best options will be included in a draft Outline Business Case (OBC) to be submitted to JAQU by the end of August 2019. The final OBC will be submitted for approval by 31st October 2019.

Stage four - the Full Business Case

Once the OBC has been approved by JAQU, a Full Business Case (FBC) will be submitted as soon as possible for final approval by UK government. Subject to agreement and funding being made available, dates will be set to start carrying out the approved measures to help make sure the air in Liverpool meets legal levels for Nitrogen Dioxide as soon as possible.
