Understanding the Emission Sources

Emissions Inventory is a database that lists, by source, the

amount of air pollutants discharged into the atmosphere of a

community during a given time period. Source: US EPA

TYPICAL SOURCES

● Mobile sources:

on-road, off-road transport

● Stationary sources: power plants,

refineries, and manufacturing

facilities

● Area sources: household cooking

and heating, small business

activities, agricultural residue

burning, waste combustion, fugitive

dust from deposits and roads,

forest fires

PURPOSE

● Helps to define key sources,

priorities and set objectives and

identify emissions reduction

measures

● Input to air pollution dispersion

model

● Assesses potential efficiency of

different reduction strategies

● Forecasts future emission levels to

determine which emission sources

might require further controls

● Primary source: Self-

Monitoring Reports (SMRs) of

over 1,000 establishments

Total and type of fuel consumed

Number of hours of operation

● Supplementary: Registered

establishments by type in 2012

(total of 212,351 )

Metro Manila Emissions Inventory

Stationary Sources: PM10 emissions

● Possible increase in use of diesel

gensets with power shortages

● Electricity demand in Luzon is

projected to increase at an

average annual growth rate of

4.13% to 10,693 megawatts in

2020.

● 869 MW committed projects are

expected for commissioning

from 2013-2015. An additional

8,100 MW is needed to meet

electricity demand.

Metro Manila Emissions Inventory

Area Sources: Commercial Grilling

● Surveyed 100 establishments

● Most use charcoal (92%),

followed by LPG (6%) and then

electricity (2%)

● Average consumption of

charcoal:

26 kg/day (2 sacks per day)

Metro Manila Emissions Inventory

Mobile Sources: PM10 emissions

Results and Key Insights

● Major PM10 and PM2.5 emission source in Metro

Manila: motor vehicles (diesel engines)

● Main emission sources from establishments are

generator sets

● Charcoal and wood fuel used for cooking are the

key contributors to area source emissions

● Understand the uncertainties (e.g., method,

emission factors, scaling due to land use)

Considerations for city-level solutions

● Mobile sources

• Improvement of public transport system in the city

• Promotion of non-motorized transport (walking and cycling) to

reduce need for motorized travel

• Cleaner engine technology options for jeepneys

• Improve the inspection and maintenance system

● Stationary sources

• Proper inspection and maintenance of generator sets (e.g.,

awareness raising)

● Area sources

• Awareness raising campaign on health impacts from area

sources, especially commercial grilling

• Assess feasibility of fuel-switching from charcoal and firewood

What can we do with the results?

Dispersion map for Metro Manila. USEPA-IES Study, 2005

Modeling Fine PM Dispersion in Metro Manila

Objective: Strengthen air quality management in

Metro Manila • Improve understanding of PM pathway in Metro Manila

through an updated dispersion map and improved

emissions inventory

• Work with stakeholders to ensure continued engagement

in AQM

Scope: 16 cities and 1 municipality; emissions from

mobile, stationary and area sources; focus on PM10

and PM2.5
