EXECUTIVE SUMMARY
The Environmental Management Bureau (EMB) of the Department of Environment and
Natural Resources (DENR) as tasked by the Philippine Clean Air Act (RA 8749) prepares
the required National Air Quality Status Report (NAQSR). The NAQSR serves as a basis for
evaluation of current programs and formulation of policies to improve air quality. To further
the relevance and application of NAQSR, this latest edition also presents the drivers of air
pollution (urbanization, economic growth, energy consumption and mobility), success stories
and best practices; challenges and problems encountered; public awareness and
environmental education programs; research outputs and activities of the different
stakeholders including various government agencies, civil societies, and the international
development community.
The Philippines’ socio-economic conditions for 2010 are presented as follows: the Philippinepopulation has an estimate of 92.3 million (92,337,852), a 2% of the world’s population, with
a growth rate of 1.9% which is higher than the world growth rate of 1.1%; Philippines wasranked 12th out of 220 countries in terms of population. In 2010-2015, Philippine urban
population is 49% with 2.3% estimated annual rate of urbanization and as of 2011, the
Philippines has 138 cities, majority of these cities have a population between 100,000 to
500,000 persons. The most populated and dense cities are located in the NCR and in the
neighboring regions. The Philippines’ gross domestic product (GDP) grew by 7.3% in 2010from 2009, 1.1% in 2009 from 2008, for the year 2010, GDP per capita was at P148,
645.21(about US$ 3,500), showing an increase from 2009 figures, which was at US$3,300.
It implied an increase in the country’s economic growth likewise in the spending capacity perindividual. Economic growth brings increased demand for mobility, energy, goods and
services which may result in increased air pollution, if policies and measures are not in place
to manage this adverse impact. The total primary energy supply (TPES) of the country is
somehow stable in 2000 from 39.3 million tons of oil equivalent (MTOE) to 40.7 MTOE in
2010, an increase of 3.6%. The country’s renewable energy share is among, if not thehighest in the world. The transport sector has the highest percent share in oil consumption,
having consumed 9,002.67 kTOE of the total 24,744.96 Ktoe. The share of coal and oil-
based sources however has been increasingly reduced through replacement of natural
gases and other renewable energy sources.
Air pollution may be due to natural or human-made (anthropogenic) sources. For the
purposes of formulating air quality management strategies, sources of pollution may be
classified into stationary, mobile and area. Definition of stationary, mobile and area sourcesare defined from RA 8749.EMB Regional Offices compile emissions inventory every three
years pursuant to the RA 8749 and consolidated to a national emissions inventory. Using the
results from the 2009 National and Regional Emissions Inventories, the emissions of the
following pollutants – particulate matter (PM), sulfur oxides (SOx), oxides of nitrogen (NOx)and volatile organic compounds (VOC), carbon monoxide (CO) are determined. Due to
limitation of resources, it is noted that not all EMB Regional Offices are able to compile
emissions to achieve 100% coverage of all of the sources. As expected, VOC, NO x and CO
emissions primarily come from mobile sources. More than half of PM emissions were from
area sources, while stationary sources were mostly responsible for SOx emissions.

Air quality monitoring is routinely conducted by the EMB Regional Offices. Aside from EMB
Regional Offices, some cities also conduct their own air quality monitoring activities funded
from internal city funds or international projects, as in the case of Iloilo and Cagayan de Oro.
EMB-DENR is planning to expand the air quality monitoring activities in the country. The
bureau aims to install at least one PM2.5 monitoring station each for highly urbanized cities by
2013.
Out of 17 regions, only seven regions are capable of PM10 monitoring. The station located inCaloocan has the highest recording of PM10 at 167 µg/Nm3. Another station with high levelsof PM10 is at MRT-Pasay-Taft station where the annual average reading of 2010 was at 130µg/Nm3. Only seven regions have complete data on TSP emissions for 2010 and 2011. Interms of geometric mean, Region 9 and NCR have the highest TSP levels and Region 12the lowest TSP levels for both 2010 and 2011. Although TSP readings have declined since2004, all exceeded the air quality guideline value of 90μg/m3.
A large number of studies has demonstrated that air pollution is associated with a range of
adverse health outcomes, ranging from mortality to subclinical respiratory symptoms. TheWorld Health Organization (WHO) estimates that air pollution causes 3.12 million premature
deaths worldwide - 1.15 million due to urban outdoor air pollution and 1.97 million due to
indoor air pollution (WHO, 2009). Data from the Philippine Health Statistics expressed that
four out of 10 leading causes of morbidity in 2008 were attributed to air pollution, i.e. acute
respiratory infection, acute lower respiratory tract infection and pneumonia, bronchitis, and
heart diseases. In 2010, 1,948 (17%) cases and 1,561 deaths out of 11,458 cases and 9,184
deaths from all medical causes were attributed by the Philippine Cancer Society to air
pollution, having an attributable fraction of 17%. The total direct costs of the effects of
particulate matter on respiratory health due to exceeding air quality guideline values in Metro
Manila alone amounted to PHP 368.8 million and PHP 400 million in 2004 and 2007,
respectively.
Air pollution especially ozone has been known to affect agricultural yield of some crops such
as rice, tomato and pumpkin. In some Asian countries, crop yield has already decreased by
between 5 and 35%. Studies estimate that the yield of rice, wheat, and legumes – Asia’sstaple crops—will decrease even more as ozone production is expected to increase rapidly.In the Philippines, rice and corn are common agricultural products that could be affected by
air pollution. In the New Year’s Eve of 2011, only six out of nine stations in Metro Manilaexceeded the guideline values but in New Year’s Eve of 2012, all of th e stations exceededthe same guideline values. The Clean Air Act established the National Ambient Air Quality
Guideline Values (NAAQGV) to protect public health and safety, and general welfare. Thesewere based on the US Environmental Protection Agency, European Union, WHO air quality
guidelines or standards applicable at that time RA 8749 was drafted and adopted.
Airsheds are designated areas with similar climate, weather, meteorology and topology
which affect the interchange and diffusion of pollutants in the atmosphere. They are also
areas which share common interest or face similar development programs, prospects or
problems. As of 2011, there are 20 airsheds established in the Philippines. Pursuant to
Section 14 of RA 8749, the Air Quality Management Fund (AQMF) was established as a
special account in the National Treasury administered and managed by the DENR through
EMB. A third of the AQMF is normally reserved for national purposes while two-thirds is
allocated to airshed management. The Fund finances: 1) containment, removal and clean-up

operations of the government in air pollution cases; 2) restoration of ecosystems and
rehabilitation of areas affected by violators of RA 8749; 3) research, enforcement and
monitoring activities, and capability-building of implementing agencies; and 4) provision of
technical assistance to implementing agencies to finance similar activities undertaken within
an airshed.
For the period 2010-2011, the following DENR Administrative Orders (DAOs) were
published: Guidelines on the Use of Alternative Fuels and Raw Materials in Cement Kilns
(DAO 2010-06); Re-designation of the Metro Manila Airshed into three individual Airsheds
and establishment of their Governing Board (DAO 2011-11); and Clarificatory Guideline on
DAO 2000-81, Part VI, Rule XIX, Section 13 of the IRR of RA 8749 (Memorandum Circular
[MC] 2011-004). Meanwhile, the DOE has started the process on the update/revision of the
Fuel Quality Standards for Stationary and Mobile Sources. A draft of the update is expected
by 2012 for finalization and promulgation.
Monitoring and enforcement of policies and regulations related to stationary sources is
primarily done through EMB Regional Offices (ROs). ROs survey, issue permit and monitor
firms, furnish information on the levels of criteria pollutants to local government units (LGUs),
provide technical assistance to stakeholders, and conduct information, education and
communication (IEC) activities. Based on the regional reports submitted by five regions, a
total of 142 NOVs and 2,432 PTOs were issued in 2010-2011. Two cases resulting in a
dismissal and an issuance of a Cease and Desist Order (CDO) were filed at the Pollution
Adjudication Board (PAB) in 2010 while three cases were filed in 2011 resulting in an
issuance of a CDO, a final lifting order, and a temporary lifting order. Aside from the EMB,
the different LGUs have also implemented systems that aim to manage emissions from
stationary sources such as manufacturing plants, companies and businesses operating
within their boundaries.
In relation to mobile sources, the following DAOs and Department Circulars were released in
2010 and 2011:Revised Emission Standards for Motor Vehicles Equipped with
Compression-Ignition and Spark Ignition Engines (DAO 2010-23);Revised Emission
Limits/Standards for Motorcycles/Tricycles and Mopeds (DAO 2010-24); and, Mandatory
Bioethanol Blending (Department Circular No. 2011-002-001). Local government units also
assist in addressing pollution from mobile sources through their anti-smoke belching
programs. In 2011, 60,444 vehicles underwent smoke-belching tests in Metro Manila. The
LTO also conducts roadside apprehensions to accost smoke-belching vehicles. From 2000
to 2008, LTO recorded the highest number of apprehensions in 2006. On August 2011, Air
Quality Management Section (AQMS) personnel of EMB conducted garage emission testing
of public utility buses (PUBs) operating in Metro Manila. Fourteen bus terminals, with a total
of 840 authorized vehicles, were visited. Out of the 840 vehicles, 191 units (22.74%) were
tested - 175 vehicles (91.62%) found to be in compliance with the standards, while 16 units
(8.38%) failed to comply. It was observed that compliance to emission standards is not
dependent on the age of the engine as long as proper preventive maintenance system is
undertaken on a regular basis. As part of the “Linis Hangin Program”, a seminar/training on“Fuel Efficiency and Motor Vehicle Preventive Maintenance” was conducted to educate busoperators, drivers and mechanics on the proper preventive maintenance processes. The
regulations and policies to reduce pollution from area sources may also be covered by other

laws – e.g. ban on waste burning – under the Ecological Solid Waste Management Act of2000, or construction permit systems by local government units.
Area sources of pollution are by nature complicated to manage because of the lack of
distinct points for regulation such as a stack for stationary sources and tailpipe for mobile
sources. A key challenge to enforcing measures on area sources is the assumed yetindistinct mandates or the lack of strong collaborations with other agencies on related
measures – e.g. ban on firecrackers by DOH which looks into the regulation of firecrackersfrom the perspective of safety as compared to environmental health.
The EMB, through its Environmental Education and Information Division (EEID), has
initiated, in partnership with the EMB’s Air Quality Management Section (AQMS), othergovernment agencies, private organizations, and the civil society, three major public
awareness and education campaigns on air quality management, all under the Linis Hangin
program are the following:
The Clean Air 10 Plus One Forum held in 2010 was organized with the theme,“Moving the Clean Air 10 Declaration: A Step Forward” and the two-day Clean Air10+2 Forum held in 2011 was with the theme, “Strengthening Partnerships towardsCleaner Air and Climate Action”. Both stressed the need to strengthen partnershipsand coordinated action toward cleaner air.
EMB, in partnership with telecommunications giants SMART Inc. and Globe
Telecommunications, came up with the Text Brigade Campaign involving the general
public via MMS (Multi-media Messaging Service). The EMB-EEID provided
assistance to the EMB-AQMS as DENR, through the EMB, inked an agreement with
major government agencies and a media watchdog to further strengthen itscampaign against smoke-belchers. Among the signatories of the Memorandum of
Agreement (MOA) were the DENR, DILG, DOTC, Metro Manila Development
Authority (MMDA), mayors of Metro Manila, the Kapisanan ng mga Brodkaster ng
Pilipinas (KBP), and the Philippine Medical Association (PMA).Information and
education campaigns have been likewise facilitated in the regions through EMB
Regional Environmental Education and Information Sections (EEIS). Achieving
healthy levels of air quality requires multiple stakeholder effort and using different
mechanisms.
Some of the initiatives undertaken by different organizations in the period 2010-2011 are the
following:
In a collaborative project with DOH and DENR, Makati City localized environmental
health monitoring by conducting its own survey of pollutant exposure in specified
stations in the city;

funding support from the Philippine Institute of Petroleum (PIP), the project swapped
old 2-stroke motorcycles which emit higher levels of CO and PM, with brand new 4-
stroke motorcycles benefitting members of the Mandaluyong Federation of Tricycles
Associations (MAFETA) and the Pasig S-Tricycle Operators and Drivers Association
(TODA);
PCA, together with the Electric Vehicle Association of the Philippines (EVAP),
Meralco and other stakeholders, organized the 1st Electric Vehicle Summit in 2010.
The summit brought together various stakeholders from the private sector, academe,
civil society, and government, which led to the formation of the Electric Vehicle
Alliance of the Philippines;
“Iwas Paputoxic” Campaign on Firecrackers of Eco-waste in partnership with theMiss Earth Foundation, Ministry of Ecology of the Our Lady of Remedies Parish in
Malate, and the Philippine Animal Welfare Society to organize creative events for thepublic to understand the ill-effects of firecrackers including its impact on air quality;
Padyak Project, as part of its long-term advocacy for non-motorized modes oftransport, ESI, together with Don Bosco Technical College, modified the design ofthe pedicab to provide drive train durability, driver convenience, passenger comfort,vehicle safety and economic viability.

German International Cooperation (GIZ), Clean Air for Smaller Cities. Clean Air for
Smaller Cities is a project financed by the German Federal Ministry for Economic
Cooperation and Development that aims to improve air quality in non-metropolitanareas of selected Association of South East Asian Nations (ASEAN) cities, including
those in the Philippines. Iloilo and Cagayan de Oro were selected to participate in the
project.
EANET, As the National Center of the Acid Deposition Monitoring Network in East
Asia (EANET), the EMB continues to conduct monitoring activities on wet deposition
and dry deposition to measure concentrations and fluxes of acidic substances
deposited to the ground. In lay terms, this refers to acid precipitation or acid rain or
soil acidification. The monitoring data indicate that the acidification, if any, is
insignificant or at very low levels.
The Philippine Nuclear Research Institute has conducted the monitoring of PM10 inthe air since 1998 to identify major sources of air pollution and estimate theircontribution from multi-element data. Recent studies have identified black carbon(BC) as a short-lived climate forcer – or pollutants that contribute to global warming.Reduction of black carbon has been considered, therefore, as a short-term solutionto climate change while waiting for mitigation measures for the GHGs to take effect inMetro Manila.
Considering the existing challenges and future development plan, recommended steps and
measures for National Air Quality Management are focused in four main aspects – policy,research and development, capacity building and institutional framework, and finance, whichvarious stakeholders can consider to implement in the immediate or long-term periods, with
strong support at the national and local levels of governance in the country.

1. INTRODUCTION
1.1. About the National Air Quality Status Report
The Philippine Clean Air Act (RA 8749) requires the annual preparation of a National Air Quality
Status Reports (NAQSR) as a basis for evaluation of current programs and formulation ofpolicies to improve air quality.1 The Environmental Management Bureau (EMB) is tasked to
prepare the Report which shall contain:
A summary of the extent of air pollution in the country, per type of pollutant and per type
of source;
An analysis and evaluation of the current state, trends and projections of air pollution;
An identification of critical areas, activities, or projects which will need closer monitoring
or regulation;
Other pertinent qualitative and quantitative information concerning the extent of air
pollution and the air quality performance rating of industries in the country.
Recommendations for necessary executive and legislative action; and,
Since 1999, four NAQSRs have been issued covering the following years: (1) the 1970s up to
2002; (2) 2003-2005; (3) 2005-2007; (4) 2008-2009. This Report will be the 5 th edition covering
2010 and 2011.
In addition to providing information mandated above, the NAQSR also presents the drivers of air
pollution (urbanization, economic growth, energy consumption and mobility), success stories
and best practices; challenges and problems encountered; public awareness and environmental
education programs; research outputs and activities of the different stakeholders including
various government agencies, civil societies, and the international development community.
This edition of the NAQSR will cover analysis on pollutants covered by RA 8749, as follows:
total suspended particulate matter(TSP), particulate matter with aerodynamic diameter of 10
micronsor smaller (PM10), Sulfur dioxide (SO2), Nitrogen dioxide (NO2), photochemical oxidants
as Ozone (O3), Carbon monoxide (CO) and Lead (Pb), including other air pollutants that may
have impacts on public health and the Philippine environment.
Since 2004, EMB Regional Offices have been required to compile their own annual Regional
Ambient Air Quality Status Reports.
1.2. National and Socio-Economic Conditions of the Philippines
The Philippines is an archipelago of 7,107 islands, with a land area of 299,764 km 2. The
Philippines is located to the east of Indochina and to the north of eastern Indonesia. The country
is bounded by the Pacific Ocean on the east, the Celebes Sea on the south and the West
Philippine Sea on the west and north.

As of March 2012, there are 17 regions, 80 provinces and 138 cities.3 Metro Manila or the
National Capital Region (NCR), the country’s capital, is an urban agglomeration composed of 16cities and one municipality.4 It has a population of 13.9 million, making it a megacity.5
The Philippines is located in a tropical climate zone and has two distinct seasons—rainy (Juneto November) and dry (December to May). The temperature ranges from 25.5°C in January to
28.3°C in May, and remains fairly high throughout the year.6 The climate of the Philippines is
influenced by the complex interaction of various factors such as geography, principal air
streams, ocean currents, among others. The country is also frequented by typhoons which help
in the dispersion of air pollution in cities.
Population and Urbanization
The Philippines has a population of 92.3 million (92,337,852) according to the 2010 census.7
While the country accounts only for less than 2% of the world’s population, its growth rate of1.9% is higher than the world growth rate of 1.1%.Philippineswas ranked 12th out of 220
countries in terms of population in 2010.8
The share of the urban population is 49% with an estimated annual rate of urbanization of 2.3%
for the period 2010-2015.9 As of 2011, the Philippines has138 cities.Statistics indicate the
steady increase of urban population along with an increasing total population (Figure 1). On the
other hand, rural population remained stable for the past decade, apart from a slight decrease in
2001.

Economy and Industry
The Philippines’ gross domestic product (GDP) grew by 7.3% in 2010 from 2009, 1.1% in 2009from 2008, 3.7% in 2008 from 2007, and 7.1% in 2007 from 2006 (Figure 3). The Servicesector, has the highest percent share of the GDP, at 54.4%, followed by the Industry sector at33.3% and by the agriculture, fishery and forestry sector at 12.3% (2011 estimate).12For theyear 2010, GDP per capita was at P148, 645.21(about US$ 3,500), showing an increase from2009 figures, which was at US$3,300. It likewise implied an increase in the spending capacityper individual. Economic growth brings increased demand for mobility, energy, goods andservices which may result in increased air pollution, if policies and measures are not in place tomanage this adverse impact.

Energy
Despite the rapid growth in population, the total primary energy supply (TPES) of the country issomehow stable where in 2000 it was at 39.3 million tones of oil equivalent (MTOE) andincreased 3.6% to 40.7 MTOE in 2010. To ensure energy security, the country includes a targetof self sufficiency from indigenous energy sources. The energy self sufficiency has beenincreasing generally since 2000 but 2010 self-sufficiency (57.5%) share has reduced slightlyfrom 2009(59.2%) (Figure 4).

2. SOURCES OF AIR POLLUTION
2.1. Sources and their Emissions
Air pollution may be due to natural or man-made (anthropogenic) sources.15
For the purposes offormulating air quality management strategies, sources of pollution may be classified into
stationary, mobile and area. From RA 8749, stationary, mobile and area sources are defined as
the following:
Stationary source – any building or immobile structure, facility or installation which emitsany air pollutant
Mobile source – any vehicle/machine propelled by or through oxidation or reductionreactions, including combustion of carbon-based or other fuel, constructed and operated
principally for the conveyance of persons or the transportation of property or goods that
emit air pollutants as a reaction product
Area source – relatively large areas of specific activities that generate significantamounts of air pollutants.
The detailed sources are listed in Table 3.
Table 3. Sources Included in 2009 Emissions Inventory
Stationary Sources Mobile Sources Area Sources- Power generation- Steel- Food manufacturing- Paper- Refineries- Cement- Chemical plants- Among others
- Diesel and gasoline-fedvehicles from cars, utilityvehicles, buses, trucks,motorcycles
- Gasoline refilling stations- Structural constructions- Dust resuspension for paved
and unpaved roads- Open burning- Agricultural activities- Residential fuel burning- Livestock- Structural fires- Dry cleaning- Kaingin- Surface Coating- Structural and Automobile
Fires- Dry Cleaning- Industrial Degreasing
Source: EMB
15As defined in the Implementing Rules and Regulations of R.A. 8749, air pollution is the “alteration of the physical, chemical and biological
properties of the atmosphere, or any discharge thereto of any liquid, gaseous or solid substances that will or is likely to c reate or to render the
air resources of the country harmful, detrimental, or injurious to public health, safety or welfare or which will adversely affect their utilization
for domestic, commercial, industrial, agricultural, recreational, or other legitimate purposes” (Environmental Management Bur eau, 2000).

EMB Regional Offices compile emissions inventory every 3 years pursuant to the RA 8749.
These regional emissions inventory is then consolidated to a national emissions inventory. This
report usesresults from the 2009 National and Regional Emissions Inventories.
The inventory covers emissions of the following pollutants – particulate matter (PM), sulfuroxides (SOx), oxides of nitrogen (NOx) and volatile organic compounds (VOC), carbon
monoxide (CO). Due to limitation of resources, it is noted that not all regions are able to compile
emissions to achieve 100% coverage of all of the sources.Table 4lists the coverage of
emissions from the regional offices.

As expected, VOC, NOx and CO emissions primarily come from mobile sources (Figure 15).
More than half of PM emissions were from area sources, while stationary sources were mostly
responsible for SOx emissions.
Figure 15. National Emission Inventory by Sources and Criteria PollutantNote: Coverage of emission sources is not 100%
Stationary Sources
Only EMB-NCR was able to disaggregate its emission inventory by industry source in 2011,results of which are shown inFigure 16. Stationary sources contribute mostly to SOx and PMofthe nine stationary sources identified, food manufacturing was responsible for highestcontribution to PM (91%), SO2 (40%), NOx (25%), and CO (64%). Paper and packagingmanufacturing contributed the most to VOC emissions (25%) while chemical and allied productswere second to food manufacturing in most emissions for PM (4%), SOx (33%), and NOx (25%).

According to the Land Transportation Office (LTO), the total number of registered vehicles in
2010 reached 6,849,784, a spike from 2000 figures of 3,796,274(Figure 17). From 2000 to
2010, the numbers grew by 80.4% with the most recent annual vehicle growth rate from 2009 to
2010 at 6.75%. Of all the vehicles, motorcycles and tricycles had the highest growth rate at
8.9% from 2009 figures while trailers had the lowest growth rate at 1.9%.Metro Manila, alone,
reached a vehicle population of 1,814,753 in 2005, which increased to 1,904,395 in 2010.

Figure 17. Number of Vehicles (in thousands) in the Philippines (2000-2010)Source: LTO
Motorcycles and tricycles comprised 53% of the total vehicles in the Philippines in 2010. Two-
and three-wheeler vehicles emit high amounts of major pollutants (i.e. CO, NO x, PM10, VOCs)
andgreenhouse gases(GHG).They also contribute to noise pollution, and to the adverse effects
on the human respiratory system. The Philippine government has recently acted on its interest
in shifting to electric 2- and 3-wheelers.16 Experiences in Vietnam and India indicated that
following electric vehicle adoption and reinforced by aggressive supportive policy, emissions
could be reduced, in some cases, to a maximum of 42%.17
The Transport sector consumed the most diesel fuel in 2010 and 2011 at 3,059 million liters and2,990 liters, respectively. It also had the highest percent share in gasoline consumption at 86%
in 2010, and 83% in 2011 (Figure 18).

Motorization indices refer to the number of vehicles per 1,000 inhabitants and are indicative of
an area’s economic development and its impact on the environment. A high motorization indexcorresponds with a high level of economic development and quality of life, but may pose a
burden on the environment because of the extensive use of energy sources, local air pollution
and development of road networks.18NCR had the highest motorization index at 137.3 followed
by Region II at 75.9 and Region III at 75.5. Majority of the vehicles from Region II and Region IIIwere comprised of motorcycles and tricycles, which have a motorization index of 46.6 out of
75.9 and 37.2 out of 75.5, respectively. Out of the 5 regions with the highest indices, 4 were
located in Luzon alone (Table 5).
Over all, vehicles, motorcycles and tricycles have the highest country motorization index at
449.63 followed by diesel utility vehicles at 148.04, but the gap between the two vehicles is
considerably large.

2007.19Regardless of expanding roads, however, traffic congestion is still a persistent problem.
Meanwhile, the amount of pollutants emitted by vehicles is going up.
With government-led programs, the country has also experienced an increased interest in
compressed natural gas (CNG) and liquefied petroleum gas-fuelled vehicles. According to the
DOE, as of 2010, there were 41 CNG fuelled buses commercially operating along Batangas-
Laguna-Manila route which is estimated to have displaced 2.7 Million liters of diesel in 2010 and
3.3 Million liters of diesel in 2011. By end of 2011, there were 19,052 taxi units using auto-LPG
(increased from 17,500 taxi units in 2010) displacing an estimated 136 Million liters of gasoline
in 2011. Electric vehicle population is also increasing and numbered 560 units by end of 2010.20
Despite the continuous improvement of fuel and compliance of oil companies with fuel
standards, air quality of major cities remains poor. It may possibly be attributed to the poor
maintenance of vehicles, overloading, and congestion, which contribute to increased emissions .
Area Sources
The most common area sources are road dust, construction activities and waste burning. Thepast decade has seen a growing number of construction activities especially in the urban areas
in the country. In 2010, most of the construction projects were concentrated in Region IV-A or
CALABARZON (Figure 19).CALABARZON had a percent share of 25.9% (or 29,379 projects) of
the construction projects followed by NCR at 12.9% (or 14, 623), and Central Luzon at 12.8%
(14,541). A total of 113,230 new construction projects were approved in 2010, which was a
slight increase of 1% compared to 112,102 construction projects in 2009.

Aside from EMB regional offices, some cities also conduct their own air quality monitoringactivities funded from internal city funds or international projects, as in the case of Iloilo and
Cagayan de Oro.
EMB-DENR is planning to expand the air quality monitoring activities in the country (Table

Only 7 regions have complete data on TSP emissions for 2010 and 2011. Most TSP readings
per region are sparsely distributed, except for Region 12. In terms of geometric mean, Region 9
and NCR have the highest TSP levels and Region 12 the lowest TSP levels for both 2010 and
2011. Although TSP readings have declined since 2004, all exceeded the air quality guideline
value of 90μg/m3.

4. IMPACTS OF AIR POLLUTION
4.1. Impacts on Health
A large number of studies have demonstrated that air pollution is associated with a range ofadverse health outcomes, ranging from mortality to subclinical respiratory symptoms. The World
Health Organization (WHO) estimates that air pollution causes 3.12 million premature deaths
worldwide - 1.15 million due to urban outdoor air pollution and 1.97 million due to indoor air
pollution (WHO, 2009). The morbidity and mortality risks due to air pollution are also highest in
developing countries. An international review of various health-air pollution studies also
concluded that the risks are even higher if you live within 300-500 meters from major
thoroughfares.21
In the Philippines, there are a few studies conducted by different organizations which look into
the relationship of health and air pollution. This exercise, however is not conducted on a regular
basis so studies may be conducted for different years, different scopes and using differentmethodologies.
Data from the Philippine Health Statistics expressed that 4 out of 10 leading causes of morbidity
in 2008 was attributed to air pollution, i.e. acute respiratory infection, acute lower respiratory
tract infection and pneumonia, bronchitis, and heart diseases.
In 2008, 65,887 (4%) out of 1,647,178 cases of acute respiratory infection, 327,684 (42%) out of
780,199 cases of acute respiratory tract infection and pneumonia, 218,325 (42%) of 519,821
cases of bronchitis, and 5,207 (16%) out of 32,541 cases of heart diseases were attributed by
the Department of Health to air pollution.22
In 2010, 1,948 (17%) cases and 1,561 deaths out of 11,458 cases and 9,184 deaths from all
medical causes were attributed by the Philippine Cancer Society to air pollution, having an
attributable fraction of 17%.
The total direct costs of the effects of particulate matter on respiratory health due to exceeding
air quality guidelines in Metro Manila alone amounted to PHP368.8 million and PHP400 million
in 2004 and 2007, respectively.23 Air pollution, along with poor sanitation and water pollution
among other environmental problems, contributed to an estimated 22% of reported cases of
diseases and nearly 6% of deaths. It also cost about PHP14 billion (US$ 287 million) per year in
lost income and medical expenses in the country.24
The Pharmaceutical and Healthcare Association of the Philippines (PHAP) reported that based
on reports from their members, respiratory-related market movement in the country increased

by 9.39% in 2011 at PHP 14.983 billionas compared to 2010 figures at PHP13.697 billion. Both
figures are more than double of the 2000 figures at PHP5.939 Billion. The relationship of the
medicine market with air pollution impacts on health however have not been studied to date.
4.2. Impacts on Agriculture
Air pollution especially ozone has been known to affect agricultural yield of some crops such as
rice25, tomato and pumpkin.26In some Asian countries, crop yield has already decreased by
between 5 and 35%. Studies estimate that the yield of rice, wheat, and legumes – Asia’s staplecrops—will decrease even more as ozone production is expected to increase rapidly.27 In thePhilippines, rice and corn are common agricultural produce that could be affected by air
pollution.
There are no existing studies in the country to date on the correlation of air pollution and
agricultural yield but this report looked into the yield trends of rice and corn. Rice and corn yield
for 2011 were one of or the highest since 2000. Corn yield fluctuated and grew very slowly
(Figure 26) while rice yield had a more stable slow growth for the same period (Figure 27).

4.3. Other Impacts
Episodic pollution causing poor visibility has been an issue of concern during the New Year’scelebrations (Figure 28). For many years now, the Manila Observatory has also been
conducting special air quality monitoring activities (for PM10 and PM2.5) around Metro Manila to
measure the effect of fireworks and firecrackers on ambient air.

Table 8 compares TSP monitoring data from New Year’s celebrations in 2011 and in 2012. IntheNew Year’s Eve of 2011, only 6 out of 9 stations in Metro Manila exceeded the guideline valuesbut in New Year’s Eve of 2012, all of the stations exceeded the same guideline values.
The EMB reported that the significant increase in TSP levels between 2011 and 2012 was
aggravated by prevailing weather conditions in NCR before and after the 2012 New Year’sCelebration. They observed that unfavourable weather conditions such as low ambient
temperature, low wind velocity, low hanging clouds (fogs), and others triggered the air pollution
episode that eventually contributed to poor visibility, which in turn resulted in the cancellation,
diversion or delay of flights (Table 9). While there are no available cost estimates to monetize
the cost of flight cancelations, diversions and delays to airlines and airports, these have also
caused inconveniences for the passengers and their well-wishers.

Despite availability of long-term air quality monitoring data during the days leading to or after the
New Year’s eve, there has yet to be a study that correlates firecrackers, air quality and healthand other impacts in the country. The existing air quality monitoring only covers particulate
concentrations but no research yet on levels of heavy metal concentrations potentially affected
by heavy metal components of fireworks. The special episodic monitoring is also limited to NewYear’s Eve and none during special events which use fireworks and firecrackers like Lunar NewYear or Pyrolympics.

The Department of Environment and Natural Resources (DENR) through the EMB,is the lead
agency in the implementation and enforcement of RA 8749. Other departments share in this
mandate through the regulation of sector activities or products affecting air quality. These
include the Department of Energy (DOE), Department of Transportation and Communication(DOTC), Department of Trade and Industry (DTI), and the Department of Interior and Local
Government (DILG). The Department of Science and Technology (DOST) provides research
and development (R&D) support in various areas. As mandated by RA 8749, local government
units play an important role in the management and maintenance of air quality within their
territorial jurisdiction. Through the years, international development organizations and civil
societies have made significant contribution in attaining milestones for the improvement of air
quality in the country.
This section will provide an overview of the achievements and challenges in addressing
pollution from different sources – categorized according to stationary, mobile and area sources.In some instances, the challenges areas for improvement may be highlighted in boxes for easyreference when they are tackled in the Recommendations Section, otherwise these are
integrated in the main text.
5.1. Ambient Air Quality Management
5.1.1. Air Quality Guideline Values and Standards
The Clean Air Act established the National Ambient Air Quality Guideline Values (NAAQGV) to
protect public health and safety, and general welfare. These were based on the
USEnvironmental Protection Agency, European Union, World Health Organization (WHO) airquality guidelines or standards applicable at that time RA 8749 was drafted and adopted. WHO
guidelines are designed to offer guidance in reducing the health impacts of air pollution, to
inform policymakers, and to provide appropriate targets for a broad range of policy options for
air quality management in different parts of the world.28

The WHO introduced the concept of Interim Targets in its 2006 Revision of Ambient Air QualityGuidelines to provide the principle of continuous air quality improvement. In other countries, thestandards are promulgated years in advance but may be for implementation at a later stage,
allowing different sectors enough time to prepare for implementation. The Philippines mayreview its standards and consider updating of the guideline values within such or similarframework.
5.1.2. Airshed Management
Airsheds are designated areas with similar climate, weather, meteorology and topology which
affect the interchange and diffusion of pollutants in the atmosphere. They are also areas which
share common interest or face similar development programs, prospects or problems. 29 As of
2011, there are 20 airsheds established in the Philippines. Table 11provides more details on
each airshed.
Activities under the airsheds include meeting with multi-stakeholders per airshed, broadeningthe regular ambient air monitoring areas in the airshed, providing updates/briefing of issues
related to air quality management, rendering of briefing of tasks and roles of new members of
the governing board, and conducting awareness-raising on the importance of air quality
management to the public.
A key challenge to maximizing the activities of and benefits from airshed management is the
lack of technical assistance and capacity which c
