Sheffield Low Emission Zone Feasibility Study The case for a national network of low emission zones Thursday 1st May 2014 Ogo Osammor
Context • The whole urban area of Sheffield was declared an AQMA (2010), for breaking the health based EU limit values for NO2gas and PM10 fine dust particles • Poor air quality costs the Sheffield economy £160m and results in up to 500 early deaths every year • Transport emissions are the biggest single contributor • Prospect of EU fines post-2015 and imminent legal action against the UK Government for NO2 breaches are focusing attention on the issue • Diesel fuel emissions have been declared a Class 1 Carcinogen by the World Health Organisation in June 2012
Air Quality Action Plan (AQAP)for Sheffield 2015 AQAP for Sheffield 2015 approved by Cabinet in July 2012 Action 1:Assess Feasibility for a Low Emission Zone Action 2: Develop Infrastructure for Refuelling Low Emission Vehicles Action 3: Promote Smarter Travel Choices Action 4: Improve Engine Performance of Commercial Diesel Vehicles Action 5: Mitigate the impact of the M1 Motorway (particularly in the Tinsley Area) Action 6: Develop Policies to Support better Air Quality Action 7: Control Industrial Emissions
Sheffield LEZ Feasibility Study –Phase 1 LEZ Phase 1 Technical Study completed November 2012 The Steering Group included key stakeholders – SYPTE / Bus Operators / SYLTP Partnership / FTA [RHA / ITS Leeds / Taxi Licensing / Public Health joined for Phase 2] The study used the Council’s Transport Model (SRTM3) • Any potential interventions that are aimed at one vehicle type alone are unlikely to remove all of the air quality problems resulting from transport emissions • We need to better understand the environmental characteristics of all types of vehicles currently travelling around Sheffield before starting to test potential interventions
Sheffield LEZ Feasibility Study –Phase 2 Traffic needs to tackle its “fair share” of NOx emissions Good local evidence base = more effective solutions Critical to understand the contribution from all different vehicle types travelling around Sheffield • Detailed Local Fleet Composition Analysis – 1.6m ANPR anonymised Data records (processed by DfT):Private Car / PHV / Hackney Carriages / LGV < 3.5T / OGV >3.5T / Buses (Council related Service Providers) • Roadsides Emissions Testing (ITS, Leeds University) @ 5 Locations

% Reduction in Total NO2 Concentrations Required (from current levels)
Why we need a LEZ Strategy • NO2 annual mean concentration predicted to exceed the EU’s 40 µg/m3 limit for NO2 at (at least) 40 locations in Sheffield in 2015 • MINIMUM of 7 years (2013) of fleet renewal alone would be required to achieve compliance with this NO2 limit at all of these sites, assuming: • there is no significant net traffic growth over this period • all the other non-traffic sources of NO2 contribute their corresponding ‘fair share’ of the required reduction • Euro 6/Euro VI performance is as expected and does not deteriorate over time • Further action is therefore required to speed up the reduction in traffic emissions, particularly NOX/NO2 • Sheffield will not pursue a formal controlled ‘London’ Style LEZ which is currently PM focused (and will apply only to Buses for NOx in 2015) Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Average NOX Emissions for Goods Vehicles & Buses by EURO Class
Desirable Features of the LEZ • Effective – targeting vehicles which contribute to current and future emissions • Efficient – targeting vehicles that are more polluting and spend more time in driving in Sheffield • Deliverable – targeting fleets over which we have some regulatory control • Affordable / Cost Effective – in terms of the size of fleet affected • Achievable – Publicly / Politically Acceptable Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Option 1: Targeting Bus & Taxi Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Option 2: Targeting Bus, Taxi & Goods Vehicles Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Option 3: Switching Diesel to Petrol(all feasible vehicle types) Results can be pro-rated by % Vehicles Switching Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Option 4: Tackling Diesel Cars (Private Car only) Results can be pro-rated by % Vehicles Switching/Removed Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D
Recommended LEZ Strategy Behavioural Change • Car – Switching 10% Diesel to Petrol • Car – 5% Reduction • Goods – 5% Reduction (more efficient driving, Ecostars, smarter routing etc) • A further 5% reduction in NOX emissions predicted Vehicle Technology • Bus – ‘Best in class’ ie Euro VI/CNG/Hybrid • Taxi – Tackling ‘worst 50%’ • Goods – Tackling ‘worst 15%’ • 6% of total fleet affected • 20% reduction in NOX emissions predicted (inc 7% from Do Min) Sheffield Air Quality Modelling – LEZ Phase 2 Steering Group Meeting D

Opportunities & Delivery Mechanisms • DEFRA funded AQAP Communications Strategy • Refreshed & Refocused AQAP for Sheffield • Re-prioritising Funding Resources – LTP / LSTF / Public Health Grant / SCRIF (and bidding for further resources) e.g. using LSTF / LTP to support CNG & EV Refuelling Infrastructure • SCC Supplementary (AQ) Planning Document • SCC Procurement
Opportunities & Delivery Mechanisms • Sheffield Bus Agreement (SBA) • Freight Quality Partnership (FQP) • HGV Routing Strategy • (Taxi Quality Partnership Agreement) • Working with key employers and commercial organisations with large vehicle fleets e.g. Council, NHS, Universities, major retailers etc.
How can UK Government help? • Ensuring UK Emissions Factors are correct (funding more research into real-life road-side emissions and the impact on health) • Clarifying national policy on diesel fuel • Promoting / incentivising low emission vehicles and refuelling infrastructure (petrol hybrid / electric / CNG) • Providing more funding for buses (CBTF / Green Bus Fund) and create a Green Taxi Fund • Clarifying national policy on tackling emissions from Motorways (and Trunk Roads) which impact on neighbouring residential areas • Continuing to support and fund local Air Quality Monitoring in order to demonstrate compliance
