1 Tuesday 16 th June 2015 Heathrow Air Quality - Briefing for LFF

2 Topics Introduction and background George Davies Management of air quality at Heathrow Andrew Chen Heathrow Expansion and air quality George Davies Questions All

3 NO 2 exceedence is an issue for London and the UK as a whole

4 Modelled NO 2 concentrations & 2014 measured values EU limit value (does not apply at LHR2) *Sites are operated by Heathrow/Local Authorities/Environment Agency and are part of the national monitoring network with the exception of LHR2 Monitoring sites around Heathrow* Above EU Limit Within EU Limit; low data capture Under EU Limit On-airport site; workplace HSE Limits apply

5 2013 Source Apportionment for NOx

6 Heathrow first published an Air Quality Strategy & Action Plan in 2000 and in 2014 published an additional target to reduce ground-based NOx emissions through Responsible Heathrow

7 The Heathrow Emissions Blueprint is a 10 point plan to reduce Heathrow s NOx emissions in 2015 Supplements existing Air Quality Action Plan with a compelling and stretched commitment Focuses on the four major sources of ground-based NOx emissions from the airport: Aircraft (70%) Surface access (17.6%) Vehicles airside (8.4%) Heating plant (4%) Action #6 focused on working collaboratively with local partners- West London Air Quality Roadmap

8 Comparison of NO x emissions from 2008/9 to 2013 Airport Source category 2008/9 (tonnes NO x ) 2013 (tonnes NO x ) Difference (%) Aircraft- elevated a Aircraft ground level b Airport vehicles (GSE) Road network c Heating plant Other d Total ground-based Non-Airport Road traffic e a From wheels off to 1000m above ground (departure) and from 1000m to touchdown (arrival) b Including taxiing, APU, and engine testing emissions c Total for emissions from airport-related trips on major road network within the 9kmx 9km rectangular study area d Includes car parking and fire training emissions e Total for non-airport related trips within the 11km x 11km major road network area f The airport-related/non-airport split is not available for road network emissions for 2008/9; for the purposes of this table they have been split in the same proportion as 2013

10 Heathrow Air Quality Working Group Comprises Spelthorne, Hillingdon, Hounslow, Slough, British Airways, Environment Agency, and Heathrow (chair) Shares and discusses air quality monitoring data and performance to help improve modelling methods and improve transparency Reviews and approves annual audit of Heathrow Air Quality Action Plan Air quality monitoring results from all local monitoring sites are published 24/7/365 on HeathrowAirwatch.org.uk (Heathrow-funded/maintained)

14 Heathrow Expansion and Air Quality

15 Airports Commission assessment findings Commission has confirmed that the Heathrow North West Runway scheme can progress within air quality limits provided mitigation measures are implemented. Overall compliance: The scheme will not affect UK compliance with national emissions ceilings set by the EU; There are no predicted exceedences of the air quality objective at any receptor, either in the do-minimum or Heathrow NWR scenarios ; The scheme would not cause any new exceedences of the annual mean NO2 concentration at which the EU limit value is set. (EU limit value 40µg/m3 annual mean);

16 Managing Air Quality Effects of the Masterplan Physical Mitigation: Airfield Efficiency: Minimise distances between runways, taxiways, aprons and stands = lower emissions; Surface Access Strategy: Avoid sensitive receptors; and No more road traffic than today. Operational Mitigation: Cleaner aircraft technology (98% CAEP/6 compliant by 2030); Cleaner aircraft operations in the sky (thresholds and glide slopes) Cleaner aircraft operations on the ground (A-CDM, FEGP, PCA) Cleaner airside vehicles (fully ULEV airside vehicle fleet); and Airport Surface Access Strategy (>50% Public Transport, CCharge).

17 Our plans place Heathrow at the heart of the transport network transforming rail connectivity Key Direct Onward Proposed 2013: 18 trains per hour 5,000 seats per hour 2030: 36 trains per hour 13,000 seats per hour

18 We will continue to innovate with sustainable travel, reduce staff car parking and make more efficient use of taxis

19 Expanding our bus network and the free travel zone to provide easier access for local communities and our workforce
