Goals of Emission Indicators in Austria
To answer national policy relevant questions: Status Trends Forecasts
Fulfillment of international reporting exercises: EU-Urban Waste Water Treatment Directive EU-Water Framework Directive EPER PRTR Eurostat / OECD Joint Questionnaire on Inland Waters ....

“Classical” Policy Demands
“Classical” indicators Population connected to collecting system and waste water
treatment plants Waste water quantities (m³) discharged (urban / industry) Organic pollutants (BOD / COD) discharged (urban / industry) Nutrients (Nitrogen and Phosphorus) discharged (urban / industry) (Dangerous substances)
“Classical” policy relevant questions: What is the % of population connected to collecting system and urban waste water treatment plants? Is pollution from urban areas and industry increasing or decreasing?

Characteristics of „Classical“ Waste Water Indicators
Focus on point sources discharging into surface waters
Policy relevant questions were related to the facts that: pollution of surface waters stemmed mainly from point sources big potential for improvement of treatment technologies and
production processes
Indicators have been the basis for regulations on limitation of discharged pollutants (production sector specific), investments, subsidies and other measures
Indicators have been used for monitoring of progress and assessment of achievement of policy goals

Nowadays Questions (Examples) with Policy Relevancy
Which measures (as e.g. required according to EU-WFD) are the most cost-effective ones? What are the costs to reduce 1 unit of a pollutant discharged
from agriculture / industry / urban areas / ....?
What are the socio-economic effects of measures (to reduce pressures on waters caused by pollution)?
What are the socio-economic effects originating from polluted waters? Health of society Economic activities dependent from clean water: e.g. fishery,
drinking water production, tourism,... Other uncertain effects of loss of healthy environment

Data Collection
A lot of „historically grown” data collections exist: National Accounts Every-day water management National reports on the status of the environment International reporting obligations (WFD, UWWTD, EPER,...)
Austrian Emissions Inventory: updated once a year with data from regional authorities (for each individual “significiant” discharger)
To further develop emission accounts1. Demonstrate usefulness to policy makers (e.g. for purposes of
EU-WFD)2. Use already existing data collections as far as possible (usually
legally binding)3. Modify data collections (and their legal basis) where this is
necessary (coverage, sector-specific aggregation)
05.04.2004 | Slide 18

Outlook
Emission accounts project in 2006: Use of data of the Austrian Emission Inventory on Surface
Waters (developed according to EU-WFD, covers “significant” point sources and diffuse sources) for NAMEA-Water Emissions (2004-2005 data)
Develop methodology for consistent time-series based on WFD-data
Overall goal: Regular update on the basis of WFD-data

Conclusion
Emission accounts are addressing nowadays policy-relevant questions
Existing data collection system is not very flexible – use of existing data sets as far as possible
Set-up specific data collections where necessary (e.g. Emissions Register)
Promotion of usefulness of (emission) accounts is very important: discussion of costs and benefits of measures discussion with different stakeholders (e.g. agriculture versus
industry as polluters of waters) monitoring of environmental efficiency definition of policy goals

data of river flow (from gauging stations) water quality (nutrient concentrations from
monitoring stations) statistical data about nutrient inputs into the
catchment geographical data (stored and analysed in a
Geographic Information System (GIS)
