Overview of the AIRUSE LIFE+ project by Xavier Querol
1. Overview of the AIRUSE LIFE+ project
Barcelona, 05/06/2015
Xavier Querol, IDAEA-CSIC
2. • Characterizing similarities & differences in PM sources & contributions across S-EU (5 cities)
• Once the main sources of PM10 and PM2.5 are identified, the strategic goal of the AIRUSE
project is to develop, test and propose specific and non specific measures to abate urban
ambient air PM in S.-EU, to meet AQ standards & to approach WHO guidelines.
OBJECTIVES
Specific objectives
• Obtaining harmonized source contributions to PM for AIRUSE cities & to identify those
responsible for exceedances of the PM limit values and WHO guidelines
• Develop, test and propose cost-effective air mitigation measures for South European
countries
• Support adaptation of control strategies for reducing PM exposure in South Europe
3. ACTION A. Preparatory actions
ACTION B. Implementation actions
A.1 Authorities and stakeholders consultation
B1. Documentation of the current status
B2. Harmonization and implementation of
source apportionment using receptor
modelling & determination of the impact of:B7. Developing & testing cost-effective PM
measures & strategies
B8. Applicability of selected measures from N
to S Europe
B3. Natural sources B4. Biomass burning
B5. Industrial sources B6. Traffic related sources
AIRUSE STRUCTURE: ACTIONS & TASKS
Intensive additional work on inventories, emission chemical profiles,
emission factors

Standards need to be established in the EU for elemental
composition of commercial wood pellets and chips to avoid the
inclusion of extraneous materials. Only Germany has standards
containing extensive trace element limits.

Remote Sensing of Vehicle Emissions (Leeds autumn/winter 2014)
Source: James Tate, University of Leeds, 2015
• Average Euro 6 NOx seven times the type approval limit (ICCT, 2014)
• Some Euro VI buses continue to have high in-use NOx emissions, depending on exhaust T (Carslaw et al, 2014)

B8. EVALUATION OF EFFICIENCY OF MEASURES IMPLEMENTED IN N&C EUROPE
15. Efficacy of LEZs
• Difficult to determine
• Confounding factors e.g.
weather, other policy
measures, recession
• Little evidence of impact on
PM10 andNO2 concentrations
outside Germany
• EC/BC reduced
B8. EVALUATION OF EFFICIENCY OF MEASURES IMPLEMENTED IN N&C EUROPE
German LEZs
•PM10 <7%↓
•Munich (LEZ + HDV ban) PM10
ca.13%↓ and NO2 <10%↓
•But not all robust studies
•Early phases studied
• LEZs apply to cars as well as
HDVs
• Generally more stringent than
elsewhere
