Emission inventory

Emission inventory - a comprehensive listing by sources of air
pollutant emissions and their relative strengths in a geographic
area during a specific time period (US EPA)

Burning
Emission inventory within AQM
4
Iterative process of air quality management by US EPA since 1970
Pittsburgh now
Why do we need EI?
5
What quantities of air pollutants are emitted in a specific area and where do they come from?
Which activities/sectors are the largest emitters of the pollution?
What types of emissions are currently controlled and how well are they controlled?
What can an EI not tell us?
6
The distance that air pollutant emissions are
transported
The amount of air pollution to which
people are exposed
The health risks from the air pollution
• Secondary pollutants (e.g., Sulfate, nitrate particles, organic particles, ozone)

Key Steps in EI Compilation
8
Key actors in EI implementation
9
1) EI manager:
• management of resources
• establish an emission inventory team (i.e. channeling communication with relevant EI experts during designing of EI scope)
• data acquisition: supervision of data collection
• internal and external deadlines
• inventory related external consultant contracts, etc.
2) EI compiler: team of experts who are responsible for compiling and documenting the EI
What are other benefits of EI?
10
Emission source contribution: prioritize
emission control
Input for 3D air quality model application
Evaluate impacts of control measures: co-
benefit analysis
Evaluation of emission trend
Review of impact of new sources of
pollution: Environmental Impact

experiences and suggest improvements
• To assess the status of data availability in the
countries/region
• To facilitate interactions with various regional and international experts for sharing
experience and lessons learned in developing methodology and database for
Atmospheric Brown Cloud Emissions Inventory

Case study: policy study
21
Before:- Kerosene main fuel for households and fisheries →
heavily subsidized by government for decades- This subsidy did not reach end-user → diverting to
industry and commercial- Presidential Decree No. 104/2007
After:- Replacing kerosene with LPG would greatly reduce
the subsidy- Energy equivalent: 1 L kerosene = 0.57 kg LPG →
LPG subsidy- Lesson: successful implementation in Malaysia and
Thailand

Emission models
• Transportation:
– International Vehicle Emission (IVE)
– Aviation Environmental Design Tool (AEDT)
• The Landfill Gas Emissions Model (LandGEM)
• Biogenic emission (GLOBEIS)
23
About IVE Model
• IVE: developed by University of California at Riverside, Center for Environmental Research and Technology (CE-CERT), Global Sustainable System Research (GSSR) and the International Sustainable System Research Center (ISSRC) Website: http://www.issrc.org/ive/
• Suitable for developing countries: many technology indexes, from pre-Euro to Euro5
• Main features:
❑ Use VSP to link with the exhaust emission
❑ Incorporate VSP bin distribution and start patterns
❑ Incorporate environmental variables (altitude, road grade, and temperature, moisture content etc.)and fuel characteristics
▪ Challenge: much effort for data collection and technology index matching
24

• Data collection and processing
– Parking lot survey
– GPS survey
– Traffic counting
• Input file preparation

Summary
36
Emissions inventories must be as reliable as possible (transparent, trackable, well-documented)
Emissions inventories need to be regularly updated, with proper documentation/tracking
The development of emissions inventory need considerations for quality assurance/quality control
Emissions inventories must consider all relevant sources of air pollutants: species, temporal and spatial distribution
There is no “perfect” emission inventory → to start as soon as possible with the available resources
