Legal basis: article 8 of E-PRTR Regulation
Article 8
Releases from diffuse sources
1. The COM, assisted by the EEA, shall include in E-PRTR information on releases
from diffuse sources where such information exists and has already been reported
by MS.
2. The information referred to in par. 1 shall be organised such as to allow users to
search for and identify releases of pollutants from diffuse sources according to an
adequate geographical disaggregation and shall include information on the type of
methodology used to derive the information.
3. Where COM determines that no data on the releases from diffuse sources exist, it
shall take measures to initiate reporting on releases of relevant pollutants from one
or more diffuse sources in accordance with the procedure referred to in Article
19(2), using internationally approved methodologies where appropriate.

• Methodological findings useful for E-PRTR

EEA’s Study: some ideas taken into account
• Main challenges
•
Source definition: need to link Annex I of E-PRTR Regulation with
the categorizations of the available Datasets (NFR)
•
Inconsistencies between E-PRTR and national inventories:
sometimes emission reported in EPER exceeds the emissions as
reported in national inventories significantly for a number of
Member States
•
Resources: sometimes data are not fully available or the cost of
gathering these data is high (specially in the case of proxy data)
•
Methodology: further work needed to compile a fully operational
methodology

Contract on diffuse emissions
2010 Contract on Diffuse Emissions to air on the basis of already
reported information under various reporting obligations
• Steering committee JRC (IES), EEA and DG ENV
• Link point sources data and national totals (e. g. CLRTAP)
• Improvement by EDGAR proxies
• EMEP layers for key air pollutants re-projected and adapted to E-PRTR
map tools (50km X 50km)
• Develop a methodology to grid emissions per sector (Transport,
Domestic heating, Agriculture,..)

Aim of the project
1) Gathering of available data on diffuse releases to air for
● NOx, SO2, PM10, CO and CO2 emissions released by
 Transport (on-road, shipping, domestic aviation)
 Stationary combustion sources, which are not covered by
Annex 1
 Industrial releases from activities which are not covered by the
E-PRTR regulation (Annex 1 and 2)
● NH3, PM10 emission from agriculture activities
● Underlying proxy data to be used for gridding diffuse emissions for
each pollutant and each sector
2) Methodology development for gridding emission data
3) Derive gridded emission map layers covering EU27 + EFTA for
selected sectors and pollutants with as a minimum a 5x5 km

Tasks
1) Methodology development
●
Methodology to incorporate EMEP grids for integration into the EPRTR website
●
Methodology for disaggregating the National totals to EDGAR level
of resolution
●
Methodology for gridding the industrial releases not covered by EPRTR => Development of a subtraction methodology
●
Development of a methodology for disaggregating national total
emissions to a higher resolution of at least 5x5 km.
2) Data Gathering
●
Emissions (NOx, SO2, PM10, NH3, CO, CO2)
●
Proxy data compilation

Tasks
3) Data processing and gridding
i.
Creating a comprehensive set of databases to store original data
(spatial and non-spatial), incl. meta data description, intermediate
derived data and final data sets
ii. Compiling of gridded emission maps with metadata based on
INSPIRE-compliant templates
4) Public Accessibility of the outcomes of the project

Make public of emission maps compiled in task through the EPRTR web-interface (not in ToR of this project)
● Dissemination document
● Preparing of short text for each layer
