About Maynilad
Maynilad Water Services, Inc. (Maynilad), an agent and contractor of the Metropolitan Waterworks and Sewerage
System (MWSS), is the Philippines’ largest private water concessionaire in terms of customer base.
In 1997, the company was granted exclusive concession rights over the West Zone by the Metropolitan Waterworks and
Sewerage System (MWSS) for 25 years. This term was extended by 15 years to enable Maynilad to increase and accelerate
investments. In 2007, the company was re-privatized in a competitive bidding won by the Maynilad Water Holding
Company Inc. – a joint venture between Metro Pacific Investments Corporation (MPIC) and DMCI Holdings, Inc. (DMCI).
Marubeni Corporation of Japan acquired a 20-percent stake in Maynilad Water Holding Company, Inc. in 2013, and
became a strategic partner of the Metro Pacific-DMCI consortium.
Maynilad is the water and wastewater services provider for the 17 cities and municipalities that comprise the West Zone
of the greater Metro Manila area. These include Manila (except portions of San Andres and Sta. Ana), Quezon City
(including areas west of San Juan River, West Avenue, EDSA, Congressional, Mindanao Avenue, the northern part starting
from the Districts of Holy Spirit and Batasan Hills), Makati (west of South Super Highway), Caloocan, Pasay, Paranaque, Las
Pinas, Muntinlupa, Valenzuela, Navotas and Malabon, all in Metro Manila; and the cities of Cavite, Bacoor and Imus, and
the towns of Kawit, Noveleta and Rosario, all in the Province of Cavite.
Maynilad operates and maintains 3 water treatment plants, 14 wastewater treatment plants, 24 water pump stations, 24
reservoirs, 7,306 kilometres of water pipelines, 35 lift stations and pump stations and 513 kilometres of sewer lines.
Twenty-four (24) of its major facilities are ISO 9001:2008 (Quality Management System), ISO 14001:2004 (Environment
Management System) and OHSAS 18001:2007 (Occupational Safety and Health Management System) certified, namely:
La Mesa Treatment Plants 1 & 2 (Water Treatment), Dagat-Dagatan Sewage and Septage Treatment Plant, Tondo Sewage
Pumping Plant, North Caloocan Business Area, Water Network Head Office and its 7 Pump Stations (La Mesa,
Commonwealth, Caloocan, D. Tuazon, Algeciras, Villamor and Noveleta) with additional 5 Pump Stations certified in 2013
(Baesa, Ermita, Patindig, Marcos Alvarez, Pagcor), La Mesa Maintenance Shop, Corporate Quality, Environment, Safety
and Health (CQESH), Central Laboratory, Warehouse (Central Depot, Arocerros, Cordillera and Valenzuela Materials
Depot) and Human Resources.
The two water treatment plants are the La Mesa Treatment Plants 1 & 2, which have design capacity of 1,500 MLD
(million liters per day) and 900 MLD respectively. A third fairly, the Putatan Water Treatment Plant (PWTP) with a design
capacity of 100 MLD which sources its raw water from Laguna Lake.
The wastewater treatment facilities for sewage, septage and biosolids, are as follows:
 Dagat-Dagatan Sewage & Septage Treatment Plant, which has a land area of 15 ha and capacity of 26 MLD. The
septage treatment plant produces 22 cu. m. per day biosolids. These biosolids are registered as organic fertilizers
of the Fertilizer & Pesticide Authority. The plant is a registered manufacturer, distributor and warehouse of
organic fertilizer.
 Tondo Sewage Pumping Plant which has 50,310 sewer service connections and pumping capacity of 432 MLD.
 Alabang Sewage Treatment Plant has a capacity of 10 MLD.
 7 lift stations (Sta. Cruz, Legarda, Port Area, Luneta, Sta. Ana, Malate and Paco),and 1 communal septic tank
(Roosevelt)
 Congressional Sewage Treatment Plant (Turned-over on Feb. 2012)
 Grant Sewage Treatment Plant (Turned-over to Maynilad Sept. 2013)
 Legal Sewage Treatment Plant (Turned-over to Maynilad Aug. 2013)

Paco Sewage Treatment Plant and Baesa Sewage Treatment Plant (Turned-over to Maynilad Aug. 2013)
In line with its Quality, Environment, Safety and Health Policy (Annex 1), Maynilad has been actively involved in different
environmental protection programs such as the Watershed Management Program. Together with the Manila Water
Company, Inc., Metropolitan Waterworks and Sewerage System (MWSS), Department of Environment and Natural
Resources (DENR), and Maynilad forged an agreement with the Bantay Kalikasan Foundation to formulate a program for
the management of Ipo and La Mesa Watersheds.
Maynilad has also tied-up with other companies, the DENR, MWSS, PLDT-Smart, the National Commission on Indigenous
People (NCIP) and the Local Government Unit (LGU) of Norzagaray, Bulacan for a sustainable tree planting program at the
Ipo Watershed. Other environmental programs are the Manila Bay coastal clean-up, Mangrove Planting Program in Cavite
City, Kawit and Bacoor, solid waste management and hazardous waste management. Aside from those mentioned
environmental programs, Maynilad is strictly complying with the regulatory requirements in wastewater discharge, air
emission and other required environmental clearances.
In addition, Maynilad has been included in the Resilient Organizations Built for Transformation of the Philippines (ROBUST
PHIL) Project. The program has a developmental objective in building capacities of the nation’s mission critical enterprises
so as to make them resilient. These enterprises would in turn be able to serve the people better, especially after a disaster
or crisis. Program would seek to achieve the objective through adoption of global best practices and alignment against
international standards on enterprise risk management, business continuity and information security.
For 2010, Maynilad participated in the Green Philippines Island of Sustainability (GPIoS). A continuation of the Green
Philippines Project, GPIoS is an attempt to change the microclimate of Metro Manila and the CALABARZON region by
creating awareness, providing technical assistance to the participating companies and advocating and aligning it with
government strategy. The Maynilad Environment Team attended trainings and workshops for the accomplishment of the
project such as Cleaner Production, Material Flow Analysis, Environmental Costs and Controlling, Project Management,
Environmental Reporting and Marketing, and Legal Compliance with the end product of accomplishing the company’s
own Environmental Report to be validated by the GPIoS team.
The IMS certified facilities of Maynilad are also maintaining energy conservation programs as part of their environment
management plan and mitigation plan regarding greenhouse gases emission. To strengthen its commitment in the
environmental protection and energy conservation, Maynilad launched the Greenhouse Gases (GHG) and Air Emissions
Inventory Development Project on February 2, 2010 in partnership with the Philippine Business for the Environment (PBE)
and Clean Air Initiative for Asian Cities (CAI-Asia). The project aims to establish carbon footprint, identify emission
reduction measures for improved environment and financial performance and establish project proposal for carbon
credits and Clean Development Mechanism (CDM). This will enhance the company’s environmental and sustainability
performance and strengthen its corporate social responsibility adherence.
The Inventory Management Plan
The Inventory Management Plan (IMP) is an important tool for maintaining the sustainability of the GHG and air pollutant
emissions inventory. It lays out the details of the inventory such as the boundaries, calculation methodologies, data
management process flows, management roles, auditing and verification and other important details. It is the blueprint of
the inventory and would serve as a guide for anyone who would want to understand the details of Maynilad’s GHG and air
1
pollutant inventory.
Maynilad’s GHG and air pollutant inventory management plan was based on the standard format that the World
Resources Institute is promoting.

Boundary Conditions
Organizational Boundaries
Organizational boundaries pertain to boundaries defined by the organizational structures and the relationships among the
parties involved. Operational boundaries are set to distinguish which emissions from the operations of the company it
emits directly and indirectly. Detailed scoping exercises were done during the initial meetings in order to properly set the
boundaries for the inventory.
Maynilad has adopted the operational approach for GHG and air pollutant emissions. This means that Maynilad accounts
for emissions of facilities over which it has full control as well as for shared facilities (i.e. office buildings, common purpose
facilities). Emissions from contracted-out activities are included in cases where reliable data are available.
List of Facilities
The initial list of facilities that were considered for the inventory can be found in Annex 2. For purposes of operation and
emissions accounting, these are categorized into the following groups:
 Central Non-Revenue Water – covers the CNRW Main Office in Bangkal and CNRW
Office in Arroceros, IMM Office (old Pasay Business Area), Meter Laboratory
 Corporate – covers the Balara Head Office (BAO, CQESH, ITS, HR, Finance, WMD,
PMD, Corporate Logistics, Commercial and Marketing), Central Laboratory,
Warehouse (Central Warehouse, Arroceros, Balara Office, Cordillera)

Emission Source Identification Procedure
The emissions sources were identified by the Green Team together with management in the planning session at the start
of the inventory process. A more detailed list of facilities and emissions sources were then compiled through a scoping
exercise by the Green Team (see Annex 3 for the complete scoping sheets)
Direct Sources (Scope 1)
Scope 1 emissions are emissions directly coming from activities or equipment within the facilities that are operationally
controlled by Maynilad. The following are identified by the Green Team as main sources of scope 1 emissions:
 Internal Combustion Engines
This category includes equipment such as water pumps, air compressors, trash pumps, forklifts,
generator set, grass cutters and lawn mowers.
 Vehicles
The emissions from company-owned vehicles are to be accounted for by Maynilad. The company
fleet composes of both gasoline and diesel vehicles. Most of them are passenger vehicles though
utility trucks and motorcycles are also present.
 Process emissions from wastewater treatment and biosolids production
Fugitive methane emissions from wastewater treatment and biosolids production are included in
this inventory.
2
The other Kyoto gases – Hydrofluorocarbons (HFCs); Perfluorocarbons (PFCs) and Sulfur hexafluoride (SF6) are not included since
these are not relevant to the operations of Maynilad
3 Lead is excluded because these are either insignificant in amounts or are irrelevant to the operations of the company. Lead is also
excluded because it has been banned as additive in fuels in the country.
4
Hydrocarbon (HC) emissions are included in the calculations as the emission factors are available.
5|Page
Indirect Sources (Scope 2)
Scope 2 emissions pertain to indirect emissions from purchased electricity. The operations of the company are dependent
on the use of electricity from the grid. Scope 2 emissions account for the generated emissions by the power plants within
the source grid and are categorized as indirect emissions.
Other Indirect Sources (Scope 3)
Scope 3 emissions refer to those generated by activities which are not operationally controlled by Maynilad but are
considered important to their operations (e.g. activities of contractors, business travel and employee commute). Scope 3
emissions from a particular activity are normally included where reliable data is available. For Maynilad’s emissions
inventory, only emissions from business air travel are included as Scope 3 emissions.
Please refer to Annex 3 for a complete listing of all Scope 1, 2, 3 emissions included or excluded in Maynilad facilities.
6|Page
Emissions Quantification
The GHG and AP emissions of Maynilad are estimated using the emission factor approach. Published emission factors
from globally-accepted emissions quantification tools and guidance materials are used while actual activity data (e.g.
electricity consumption, fuel consumption, etc.) was used whenever possible. The basic formula used in the emission
factor approach is:
A x EF x (1-ER/100) = E
Wherein:
A
= activity data
EF
= emission factor
5
ER
= emission reduction efficiency
E
= emissions
The activity data is the measure of extent of the activities, which emit emissions. An emission factor is a representative
value that attempts to relate the quantity of a pollutant released into the atmosphere with an activity associated with the
release of the pollutant. Ideally, emission factors applied are those specific for the fuel used (based on analysis of e.g. fuel
oil) or the equipment (based on emission analysis of e.g. boilers), provided analyses is conducted frequently enough to
reflect the variability of emissions over time.
Calculation tools were developed by CAI-Asia to assist Maynilad in calculating both GHG and AP emissions. The GHG
calculations in the developed tools are consistent with those of the tools of the GHG protocol. Moreover, these tools were
developed to calculate GHGs as well as criteria air pollutants, which are currently not covered by the GHG Protocol.
Scope 1: Direct Emissions
Scope 1 or direct emissions are generated by sources, which are operationally controlled by Maynilad. The sections below
explain the sources of Maynilad’s direct emissions and how the emissions are calculated.
Company-owned Vehicles
6
The calculation sheet for the mobile sources is an adaptation of the UNEP-TNT Clean Fleet Management Toolkit- Tool 18.
This was used as a basis for the calculations as it provides emission factors (CO 2 and criteria air pollutants) for the
different types of vehicles. Also, the emission factors it provides have been derived from tests done in developing
7
8
countries. The tool lacks the emission factors for CH4 and N2O, which are now sourced from the IPCC and WRI. (From
IPPC, the value for the Global Warming Potential is used as conversion factor to get CO 2 mass equivalent for CH4, 21, and
N2O, 310)
The GHG emissions are estimated by multiplying the fuel consumption of the vehicles (based on categories as explained in
the paragraph below) and their corresponding emission factors. Air pollutant emissions are estimated by multiplying
9
distance-travelled data with distance-based emission factors.
The UNEP-TNT Fleet Management Toolkit categorizes the vehicles based on weight, fuel type and the emission control
technologies found in the vehicles and/or their compliance to the Euro emissions standards. The original categories in the
toolkit are:

Most of the calculated emissions in this inventory assume no control. See the appendix for the details of the emission factors used.

To make the tool more user-friendly and more applicable to the terms being used in the Philippines, the original listing of
categories had been renamed according to the equivalent specifications, particularly the passenger car categories as
shown in the table below:
Table 4: Changes in the Categories in the UNEP TNT Clean Fleet Toolkit
Original Categories
Passenger car – Petrol - without catalyst
Passenger car – Petrol – with 3 way catalyst
Passenger car – Diesel - without particulate matter filter

Revised Categories
Passenger car – Petrol – Pre-Euro and Euro 1
10
Passenger car – Petrol – Euro 2 and above
Passenger car – Diesel – Pre-Euro up to Euro 2
Passenger car – Diesel – Euro 3 and above
Due to the limitations of the UNEP-TNT tool in terms of providing a good number of vehicle categories, the vehicles are
categorized according to their year of manufacturing, thus capturing the vehicle emission standards that they have. In the
Philippines, Euro 1 was introduced in 2003 and Euro 2 standards in 2008. Even though the vehicle classification in the tool
is limited, it gives a good overview of the emissions from the different types of vehicles in the fleet. There are vehicles,
which are compliant with higher Euro standards. If this is indicated by the manufacturer, it is important that these
vehicles be categorized into the proper group.

According to the EMEP/Corinair Emissions inventory Handbook (2007), three-way catalysts were first introduced in Euro 1 passenger
cars. This inventory, however, treats the improved closed-loop three-way catalysts, which were first introduced in Euro 2 passenger
cars, as the “3-way catalysts.”

If the odometer readings are not available, default fuel efficiency values can be used to convert the fuel consumption figures into
distance figures. The tool adopts the fuel efficiency values from the UNEP –TNT Clean Fleet Management Toolkit. If better figures,
which may closely reflect the fuel efficiency of the vehicles of the Maynilad Fleet, are available, these should be used.

that the other sources (such as LPG consumption which was initially considered but eventually excluded because little
emissions were generated) only emit a very minute amount of emissions as compared to the other sources. However,
future inventories may include other sources as well.
Fugitive Emissions from Wastewater Lagoons
When considering greenhouse gas emissions from wastewater treatment systems, there are two primary classes
of biological treatment units: aerobic treatment units and anaerobic treatment units. Some treatment units, such as
facultative lagoons, may be a mixture of the two, with aerobic zones near the surface of the lagoon and anaerobic zones
in the lower depths of the lagoon. Regardless of the type of biological treatment employed, the biochemical reactions are
similar, with organic carbon compounds being oxidized to form new cells, CO 2 and/or CH4 and water.
Maynilad accounted for fugitive emissions from wastewater lagoons of the Dagat-dagatan Sewage and Septage
Treatment Plant (DDSSTP) and emissions from the discharge pathway of Tondo Sewage Pumping Plant (TSPP), DDSSTP,
Alabang STP and Congressional STP.
In the estimation of fugitive emissions for DDSSTP, Maynilad utilized the methods stated in the Greenhouse Gas
Emissions Estimation Methodologies for Biogenic Emissions from Selected Source Categories: Solid Waste Disposal,
Wastewater Treatment and Ethanol Fermentation that was prepared by Research Triangle Institute (RTI) for the U.S.
Environmental Protection Agency (EPA).
Aerobic wastewater treatment systems produce primarily CO2, whereas anaerobic systems produce a mixture of
CH4 and CO2. Equations 3-1 and 3-2 provide a general means of estimating the CO2 and CH4 emissions directly from any
type of wastewater treatment process assuming all organic carbon removed from the wastewater is converted to either
CO2, CH4, or new biomass.
Where,
Qww= wastewater influent flowrate
OD = Oxygen demand of influent wastewater to the biological treatment unit determined as either BOD 5 or COD
(mg/L = g/m3)
EffOD = Oxygen demand removal efficiency of the biological treatment unit
CFCO2= Conversion factor for maximum CO2 generation per unit of oxygen demand
= 44/32 = 1.375 g CO2/ g oxygen demand
CFCH4= Conversion factor for maximum CH4 generation per unit of oxygen demand
= 16/32 = 0.5 g CH4/ g oxygen demand
MCFWW = methane correction factor for wastewater treatment unit, indicating the fraction of the influent
oxygen demand that is converted anaerobically in the wastewater treatment unit
BGCH4= Fraction of carbon as CH4 in generated biogas (default is 0.65)
λ = Biomass yield (g C converted to biomass/g C consumed in the wastewater
treatment process

For DDSSTP, the treatment process in the lagoons can undergo partial anaerobic and aerobic process. Thus, CO 2 and CH4

Actual BOD and COD values from the treatment process were used in the estimation of greenhouse gas
emissions from Maynilad Wastewater Treatment Systems. Influent and effluent BOD were obtained from the
consolidated laboratory results of 2009.
Maynilad also accounted for fugitive emissions from biosolids production prior to land application. It is possible
that biosolids in the form of a wet cake could generate and emit CH 4 during storage. Based on research of CH 4 and N2O
emissions from materials with similar physical and nutrient qualities to biosolids, CH 4 and N2O emissions factors were
developed and can be used in combination with the number of days that biosolids are stored in order to determine
11 | P a g e
emissions for these two GHGs (Sylvis, 2009). Estimation of emissions was based from Biosolids Emissions Assessment
Model for Determining Greenhouse Gas Emissions from Canadian Biosolids Management Practices by Sylvis (2009).
Fugitive Emissions from Biosolids Production
Fugitive emissions from biosolids production prior to land application are also included. Estimation of emissions was
based from Biosolids Emissions Assessment Model for Determining Greenhouse Gas Emissions from Canadian Biosolids
Management Practices by Sylvis (2009).
The equation used in estimating the CH4 emissions from storage of biosolids prior to land application is adopted from
Sylvis (2009).

If the solids content of the biosolids is < 55%, then:

GWP is the Global Warming Potential of CH4, which is 21
b) If the solids content of the biosolids is > 55%, then
CH4 = 0
Scope 2: Indirect Emissions from Purchased Electricity
Scope 2 emissions exclusively refer to emissions generated from the consumption of purchased electricity. Indirect
emissions from purchased electricity are calculated using emission factors calculated from official electricity data from the
Department of Energy. Due to the lack of data on the pollution abatement efficiencies of the power plants in the grid, it is
18
assumed that the abatement efficiencies are 0% to uphold the concept of conservativeness in estimation of emissions
pending availability of actual information. A single emission factor for the Luzon and Visayas grids is used because these
19
two grids are interconnected. Low-cost, must-run renewable energy resources are assumed to be zero-emissions.
The emission factor of the power grid for the baseline inventory was computed using the 2009 power generation data
from the Department of Energy (DOE). Every year, the department posts in its website the power generated for the
previous year.

For subsequent years, the emission factor of the grid needs to be updated. The
electricity generation data for the grid is used to calculate the said emission factor. The
data can be downloaded from the DOE’s Powerstats website
17
(Clemens et al., 2006 as cited by Sylvis)
Conservativeness means that emission reduction calculations shall not be overestimated.

Scope 3: Other Indirect Emissions
Scope 3 captures all the other indirect emissions, which are generated outside of Maynilad’s control but are important to
the operations of Maynilad.
Contracted-out Vehicles
The emissions from the contracted-out vehicles (if data is available) are computed using the same methodology described
in the earlier section on company-owned (Scope 1) vehicles.
Contracted-out Equipment (internal combustion engines)
The emissions from the contracted-out equipment (if data is available) are computed using the same methodology
described in the earlier section on company-owned (Scope 1) internal combustion engines.
Business Travel (Business Flights only)
Emissions from business flights are included in the inventory. The table below shows the pertinent information that is
needed to calculate the flight emissions.

In order to calculate the GHG emissions from the flights, the tool adopts the methodology of the “2009 Guidelines to
20
Defra / DECC's GHG Conversion Factors for Company Reporting”. It takes into account the uplift factor by assigning +9%
to the distance, as recommended by the IPCC Aviation and Global Atmosphere 8.2.2.3. The basic formula used in the
calculation of the GHG emissions is:
The emission factors for the GHGs are dependent on the type of flight (short, medium or long haul) and the cabin class.

For the criteria air pollutants, only NOx, CO and HC are calculated. The EMEP/CORINAIR Emissions Inventory Handbook
21
(2007) Chapter 8 was used as a guide. The said guidebook provides general emission factors for “various aircrafts” and
these were used for simplicity. The vehicle kilometers travelled are translated into the appropriate emission factors (see
Annex 4) and the resulting figure is divided by the number of passengers in the flight to get the per passenger emissions.

It is assumed that short flights (such as local flights) are done using smaller planes. The calculations assume that an Airbus
22
319 is the type of plane used in these short flights. It has a capacity of 134 passengers. For medium and long haul flight,
23
the calculations assume that an Airbus 320 is used which has a maximum capacity of 177. An 80% occupancy rate is
24
assumed as well.
Emission Factors and other Constants
Please refer to Annex 4 for the emission factors and other constants that were used in the calculations are found. If
emission factors that are more specific to the operations of Maynilad be available, these shall supersede the existing
emission factors. Any changes in the emission factors shall be noted as well as the reason for the changes.
User’s Guide for the GHG and AP Emissions Accounting Tool
The User’s Guide for the GHG and Air Pollutant Emissions Accounting Tool for Maynilad is a step-by-step guide for using
the tool and explains the different components of the sheets that are within the said tool. The User’s Guide does not
explain the logic of the calculations, the equations used, as well as the references of the default parameters that were
used. Also, it does not discuss where the inputs are to be collected from within the organization. These are documented
in the inventory management plan. See Annex 6

Data Management
This section discusses the components that are pertinent to the management of data for the GHG inventory of Maynilad.
Data Collection
Based on the identified Scope 1, 2 and 3 emission sources, an Excel-based data collection form was developed by CAI-Asia
in collaboration with the Green Team. The data collection forms would be the instrument for data collection and the data
gathered shall be linked with the calculation tools.
The Green Team has also developed simplified flowcharts, which represent how data shall be collected for the different
major emission sources of Maynilad (please refer to Annex 5).
Quality Assurance
To ensure the quality and integrity of data collected, the Green Team will meet every four months to discuss activity data
and results of emissions for internal quality assurance review. Each group (Corporate, Business Area, Water Network,
Water Production, and Wastewater Management) is responsible for ensuring quality of activity data and computed
emissions, and presenting at trimestral meetings of Green Team for internal review. Annex 5 also includes details on
which units shall be responsible for validating the primary data (from the current existing procedures) that will be used in
the inventory.
Inventory Uncertainties
GHG inventories are associated with uncertainties. For example, many direct and indirect factors related with global
warming potentials (GWP) values that are used to combine emission estimates for various GHG involve significant
scientific uncertainty. Analyzing and quantifying such uncertainty is likely to be beyond the capacity of most company
inventory programs. Moreover, it is also believed that all emissions or removal quantification are associated with
estimation uncertainty. There are two classifications of estimation uncertainty, namely: model uncertainty and parameter
uncertainty. Model uncertainty refers to the uncertainty associated with the mathematical equations (i.e. models) used to
characterize the relationships between various parameters and emission processes. Parameter uncertainty refers to the
uncertainty associated with quantifying the parameters used as inputs (e.g. activity data and emission factors) into
estimation models.
Frequency of Reporting
For internal reporting, the members of the Green Team will provide activity data and emissions results every four months
in time for discussions at the scheduled trimestral Green Team meetings. Trimestral meetings are scheduled no later than
one month after end of trimester (i.e. February, July and October). Green Team subsequently updates Top Management
Team every trimester and annually for review.
For external reporting, results of the Maynilad GHG/AP emissions accounting will be submitted to Corporate
Communications for posting in the company website.
15 | P a g e
Base Year
The base year is the year that will be used in assessing the direction of the emissions of Maynilad in the future. 2009 was
selected as the base year to account for the transition and re-organization, which took place in 2008.
Recalculation of Base Year Emissions
Structural Changes
In the event of an acquisition or subsequent divestiture, the base year and subsequent years will be adjusted to include or
exclude the applicable emissions from each acquisition or divestiture, respectively. If the acquisition or divestiture did not
exist in the base years, the base years emissions will not be recalculated and adjustments to the inventory will be made as
far back as the data is available.
Methodology Changes
If any changes to emission factors or calculation methodologies were found to result in significant differences,
adjustments will be made to the calculations for the years affected. Likewise, a base year adjustment will be made if
changes in calculations for the corresponding time frame or improvements in data accuracy lead to significant differences
in emissions. If the change is not significant that is not more than 5% or the data is not available for all past years, the new
methodology or calculation will be addressed in the report without recalculation to enhance transparency.
16 | P a g e
Management Tools
Roles and Responsibilities
The Green Team shall be responsible for the overall conduct of the GHG and air pollutant emissions inventory. Ensuring
the quality of the data collection and emissions estimation are core responsibilities of the Green Team. The management
shall be responsible for giving the overall direction of the emissions accounting and reduction initiatives of Maynilad.
Training
In preparation for the 2009 GHG and air pollutant emissions inventory, members of the Green Team participated in a twoday training workshop on the internationally accepted GHG protocol. For subsequent preparations of the GHG and air
pollutant emissions inventory, the Green Team will initiate at least one training/refresher seminar every year for both
existing and new team members.
Document Retention and Control Policy
All information and records pertaining to the IMP, activity data, emission factors and emissions inventory results are
maintained by the IMS Department for a minimum of 3 years. Version control numbers in the cover page shall be applied
which indicates that that there were revisions made in the succeeding IMPs.
Auditing and Verification
Internal Auditing
The green team shall conduct internal audit of its yearly inventory prior to finalization of the report. Internal
audit shall be conducted through cross checking by different groups of the green team or shall tap services of the
IMS internal auditors.
External Validation and/or Verification
As the Philippines currently does not have local emissions inventory auditors/validators, Maynilad has acquired
services of TUV Rheinland in reviewing the GHG/AP emissions accounting process and results of its 2009 base
year inventory. Yearly inventories shall also be subject to external validation and/or verification.
Management Review
The Green Team will update the Top Management Team (TMT) on any related recommendations every trimester. They
will also prepare an annual emissions summary for TMT review.
Corrective Action
All corrective actions for the IMP and the emissions inventory will be implemented by the Green Team within an agreed
time frame with TMT, and documented accordingly.
