Air Quality – Environmental Hazard
• AQ increasingly recognised as significant hazard in most countries in the world, including all ENPI East countries.
• Accumulating evidence showing adverse effects of air-borne pollutants on human health, agricultural crops, man-made environments (damage to building materials) and ecosystems.
• Impacts do not respect national boundaries.
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 3
Air Quality – Sources of pollution
• Air pollutants may be released by either stationary sources (e.g. a coal-fired power plant), or by moving sources (e.g. cars, buses)
• Common pollutants include particulate matter, NOx, SO2, CO, carbon dioxide (CO2), ozone (O3), (transport, energy combustion), lead (Pb), mercury (Hg), heavy metals (industry), etc.

Regional Context
• Air pollutants are emitted principally from– Heavy industries in all ENPI East countries
(e.g. Ukraine: metallurgical industries, mining, and oil processing sectors)
– Transport: In all ENPI East countries, rising levels of car ownership combined with poor levels of maintenance of an ageing car fleet
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 6
Regional Context
• Moldova: large majority of cars are not in line with technical requirements (Euro 2 and Euro 3) and are old. – More than 90% of the vehicles in Moldova are
older than 10 years (MMoT).
– The law prohibiting import of cars older than 7 years has been amended and increased the limit from 7 to 10 years.
• 23-24.06-2011 Final Project Event:ENPI-East , Chisinau 7
Regional Context
• Sources and Impacts predominantly in urban areas, where residential areas close to industry
• Trends: generally in line with levels of economic activity, though signs of de-coupling as technologies improve
• Previous studies in other world regions, plus ENPI national studies, show significant benefits of air pollutant reductions

Project Method (1)
• Benefits assessed under the project: resulting from 50% reductions from projected baseline levels of PM10, (transport) NMVOCs, (industry) NH3, (agriculture) SO2 and NOx (energy & transport) in 2020. – based on equivalent reductions typically required in countries
adopting the EU AQ Framework Directive. ((Directive 2008/50/EC)
• The selected pollutants account for majority of benefits in previous assessments
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 10
Method (2)
• Qualitative assessment– Describe various forms of impacts resulting from
AQ– Categorise benefits in terms of:
• Economic
• Social
• Environmental
• Health
– Data from in-country reviews & other assessments
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 11
Methods (3)
• Quantitative assessment– Outputs from integrated software tool called EcoSense -
assesses impacts resulting from the exposure to airborne pollutants: human health, crops, building materials. (Note: under-estimates since does not include all air pollutants).
– modelling and the calculation of impact costs follow the Impact Pathway Approach (IPA).
– Worked example in BAM for policy makers

Methods (6)
• Impacts – relative importance (% of total): – mortality (70 per cent); – morbidity (20 per cent); – crops (6 per cent);– materials (4 per cent).
• To express the results in physical terms: 1. total benefits apportioned to these splits
2.divide by unit value. (Central unit values for mortality and morbidity are €1.1 million and
€0.2 million, respectively, but need adjusting for PPP).

Environmental benefits
Description
Ecosystem condition improvements
Reduced acidification from lower SO2 and
NOx emissions Reduced climate change impacts on impacts
from lower SO2 and NOx emissions Reduced damage to vegetation from low level
ozone
Results (2)
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 17
Health benefits Description
Lower incidence of acute and chronic disease
Reductions in SO2 imply lower incidence of
cardiovascular and respiratory disease Reductions in PM10 concentrations imply lower
emergency-room visits due to asthma, and also hospital admissions on the grounds of respiratory diseases
Reductions in NOx, when combined with ozone,
organic compounds, particulates and sunlight result in corresponding reductions of photochemical ‘smog’ that otherwise cause respiratory impairment, irritation of the eyes and mucous membrane, with asthma patients and young children.
Results (2b): case study
• Carcinogenic risk for the population of a metallurgical centre, Achinsk in Krasnoyarsk region (Siberia) – at present levels of air pollution, the number
of cases of cancer will amount to 48 cases during the next 70 years, or 0.66 cases per year.

Social benefits DescriptionReduced damage to cultural heritage, including historic building surfaces in city centres
Black smoke from traffic is a prime cause of discolouring of buildings, including public buildings of important social cultural value, such as monuments, historic buildings, churches, museums
Exposure of building materials to SO2 deposition
from acidification results in premature ageing.
Reduced blackening and erosion of surfaces (from
SOx and NOx emissions from traffic fuel use), can
improve the social appreciation and use of city centres and cultural heritage.

Economic benefits
Description
‘Green technology’ industries
Increase in demand for products and processes that result in lower air pollution emissions, and subsequent employment opportunities, as long as such industries are domestic.
Increased visits to improved landscapes and natural areas
Increase in tourism and associated expenditures in local areas.
Lower material cleaning costs
Reductions in expenditures on building surfaces soiled by particulates.
Crop damage reductions
Reduced crop damage from lower SO2 and NOx
emissions Reduced crop damage from low level ozone
Results (5): quantitative health benefits (physical numbers)– The majority of health benefits in the ENPI East region are
realised in Russia

Annual Compliance: Trans-Boundary Benefits – 2020
Conclusions (1)
• Total domestic benefits (health, crops, material) of reducing emissions by 50% from projected 2020 levels in all the Eastern ENP countries
→ €200 billion per year.
• Total trans-boundary impacts (i.e. all benefits outside country borders)
→ €120 billion of benefits per year (more uncertain)
• Benefits to human health - 90% of total benefits.
23-24.06-2011 Final Project Event:ENPI-East , Chisinau 25
Conclusions (2)
• Absolute levels of benefits from 50% reduction in air pollution are high:
– average 1 – 2% of GDP, including trans-boundary effects
• Significant uncertainty in each part of the impact pathway (emissions-dispersion-exposure-impact-valuation)
• Under-estimates quantitatively since does not include all air pollutants.
• May over-estimate since assumes GDP-emissions rise together to 2020

Recommendations
• Dissemination of these results should raise awareness and add impetus to need for increased regulation
• Further country-specific analysis should be complemented by looking at costs and distributional effects of increased regulation

Outstanding questions
• What do you think are the best ways of using these results in the ENPI-East region and in your respective countries in particular?
• What additional information would you find helpful in interpreting and disseminating these results?
