Key AQ Management Policies
● 1999: Established Clean Air Act
● 2011: National Environmentally Sustainable
Transport (EST) Strategy launched
AQM Institutional Framework
● National: Department of Environment and Natural
Resources
● City: Metro Manila Airshed Governing Board
Recent Updates
● 2013: Adopted PM2.5 Guideline values
● 2016: EURO 4 compliant

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
Metro Manila Emissions Inventory
Stationary Sources: Data Sources
● 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 )

(facilities) in Metro Manila (2012)

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
