This publication is a product of the Cool Contributions fighting Climate Change (C4)
Project implemented by GIZ Proklima. It is part of the International Climate Initiative (IKI).
The Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU)
supports this initiative on the basis of a decision adopted by the German Bundestag. The
project supports an international control for F-gases in combination with increased
energy efficiency in the refrigeration and air conditioning sector. It strengthens cooperation
between various initiatives such as the UNFCCC and the Montreal Protocol by promoting
a coordinated agreement and reducing overlaps. Furthermore, the project advises s elected
partner countries in formulating national GHG mitigation strategies in the refrigeration
and air conditioning sector and thereby advancing their NDCs. The project runs from 2016
until 2021.

ACKNOWLEDGEMENTS
This report is the result of a comprehensive data collection and assessment process that has been carried out
since September 2017 within the project “Cool Contributions fighting Climate Change” (C4)* implemented by
Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and funded by the German Federal Ministry
for the Environment, Nature Conservation and Nuclear Safety (BMU) under the International Climate Initiative (IKI).
The project aims to develop a greenhouse gas (GHG) mitigation strategy in the refrigeration and air conditioning
(RAC) sector as part of the Philippines’ Nationally Determined Contributions (NDCs), including establishing
parameters for increased energy efficiency in RAC technology, finding solutions for greener RAC technologies and
fostering their marketability and local manufacturing.
The GHG inventory provides a detailed profile of GHG emissions resulting from refrigeration and air conditioning
(RAC) in the Philippines and may serve as a basis for further development of emission reduction measures in the
RAC sector in contribution to the Philippine climate targets. It shall serve as a basis for further planning of the
Philippines’ NDCs and HFC phase-down schedules in contribution to the Montreal Protocol’s Kigali Amendment.
We would like to express our gratitude for the support of all the institutions, companies and other stakeholders
in the Philippines. The conduct of this inventory was led by the Environmental Management Bureau (EMB) of the
Department of Environment and Natural Resources (DENR). The DENR is the focal agency in the GHG inventory
and mitigation action in the Industrial Processes and Product Use (IPPU) sector of the Philippine inventory system
in line with Executive Order No. 174 in partnership with the Climate Change Commission (CCC) as National
Inventory compiler. We acknowledge the EMB leadership of Director Metodio U. Turbella and former Assistant
Director Jacqueline A. Caancan for their support.
The process was a learning experience for the DENR-EMB working on an integrated approach of ozone and
climate protection. Moreover, it was a new experience to work with other national government agencies given the
cross-cutting nature of the RAC sector compliance and enforcement.
We especially thank the Lighting and Appliance Testing Laboratory (LATL) of the Department of Energy (DOE)
Energy Research and Testing Laboratory Services (ERTLS) whose expertise and collaboration were indispensable
for the realization of this report. The development of a Minimum Energy Performance for RAC appliances is a
starting point in establishing a database for all RAC appliances in the Philippines, which hopefully would be a
valuable tool in succeeding RAC inventories in the near future.

CONSUMPTION AND OTHER FACTORS
INFLUENCING THE GROWTH OF RAC
APPLIANCES
The demand for RAC appliances in the Philippines is
growing continuously with multiple factors driving this
growth (Oppelt, 2013), as listed in Table 1 below. The
growing population and number of households leads
to an increased demand for more appliances on the
market. The high GDP growth rate indicates general
economic growth, which coupled with increasing de-
mand and growing urbanisation increase the sales in the
sector. The current number of households can also give
a realistic general guidance on how many appliances
such as ACs and domestic refrigerators are in use by
the end users. The current total electricity consump-
tion in the country can be compared to the equivalent
consumption in different mitigation scenarios and thus
the potential contribution of the RAC sector to the total
country emissions abatement in case of the introduction
on nationwide programs.

Table 2 provides an overview of the Philippines’ key
institutions from private and public domains relevant for
the climate and energy conservation policy in the RAC
sector as well as key non-state institutions and stake-

THE CLIMATE CHANGE COMMISSION The Climate Change Commission (CCC) is an independent and autonomous
government body. The CCC is under the Office of the President and is the “sole
policy-making body of the government which shall be tasked to coordinate, monitor
and evaluate the programs and action plans of the government relating to climate
change”. The CCC is the political partner for the implementation of the C4 projects
in the Philippines.

defined by the IPCC.
DENR is an implementation partner for the C4 project.
THE PHILIPPINE OZONE DESK (POD) AT The POD is the national coordinating body of the Montreal Protocol for the
DENR Philippines with the mandate to manage chemical refrigerants. It has managed the
chlorofluorocarbon (CFC) phase out plan and is currently managing the hydrochloro-
fluorocarbon (HCFC) phase-out plan. The POD is also in charge in managing issues
related to the management of hydrofluorocarbon (HFC) under the Kigali Amendments,
where the ratification of the Philippines is pending. The POD coordinates policies and
climate strategies coordination related to the GHG management of refrigerants,
including national GHG emissions reporting and related inputs to the NDC.

is based on actual emissions gathered at the unit or

calculation of appliance related refrigerant emissions
as opposed to inventory methodologies based on the

The latter approach is usually applied for estimating
emissions as part of ozone depleting substances (ODS)
