GHG Inventory

GHG Inventory

Greenhouse Gas (GHG) Inventory

Presentation Objectives

• Enabling policies, benefits and advantages for LGUs in conducting community-level GHG inventory;

• Approaches in conducting community-level

GHG inventory;

• Sectors and Sub-sectors included in GHG

inventory

Republic Act 9729 or Climate Change Act

• Section 14 of The Climate Change Act specifically recognizes the role that LGUs play in

mainstreaming climate change efforts within the government and requires them to formulate and

implement local climate change action plans (LCCAP) that is consistent with local and national

policies and frameworks.

• Section 3.3.5 of the Guidelines for the Formulation of the LCCAP strongly suggests LGUs to

identify mitigation options to help reduce their carbon footprints and contribute to efforts in

addressing climate change

Good GHG accounting system can provide:

 Understanding of current and historical emissions

 Insights to project future emissions (baseline)

 Information needed to prioritize action

 Data needed to monitor and assess action

GHG accounting is:

 Critical to achieve GHG emission reduction goals

potential co-benefits

GHG ACCOUNTING BENEFITS

SECTORS & SUB-SECTORS FOR

COMMUNITY-LEVEL GHG INVENTORY

Fuels used by residential and commercial sectors for cooking, lighting,

heating and cooling within the geopolitical boundaries of the LGU.

• Residential Buildings

• Commercial & institutional buildings & facilities

• Manufacturing industries and construction

• Energy industries

• Agriculture, forestry, and fishing activities

Fuels used for on-road transportation within the geopolitical boundaries

of the LGU. On-road transportation are vehicles used for transportation.

There are two methods to collect activity data for mobile combustion:

• Distance-based Method

• Fuel-based Method

**Fuel-based method is preferred and most commonly used

Electricity consumed within the geopolitical boundaries of the LGU.

Data on total community electricity consumption should be secured from the electricity providers

(e.g. utility company or electric cooperatives) or from government offices.

Emissions from industrial production processes that chemically or

physically transform raw materials:

• Mineral Industry

• Chemical Industry

• Metal Industry

• Non-Energy Products from Fuels and Solvent used

• Electronics Industry

• Products Used as Substitute for Ozone Depleting Substances

• Other Product and Manufacture Use

• Others such as Pulp and Paper and Food Industry

Emissions from waste facilities should be calculated using any of the following in cases where

the waste is landfilled:

• First order decay (FOD) model at disposal sites; or

• ICLEI-based waste quantification methodology (which estimates future emissions of current waste

generation);

Emissions with associated with Methane (CH4) and Nitrous Oxide (N2O) emissions from waste water and

sewage. LGUs should account for CH4 and N2O emissions coming from the following sources:

• Waste water generated inside the LGU’s geopolitical boundaries

(Scope 1).

• Wastewater generated/received from outside the geopolitical boundaries of the LGU, but treated

within the boundaries of the LGU (Scope 1).

• Wastewater generated by the LGU but is treated outside the

geopolitical boundaries of the LGU (Scope 3)

GHG EMISSIONS CALCULATIONS

Greenhouse Emissions = Activity Data x Emission Factor

Activity Data

The magnitude of human activity resulting in emissions or removals taking place during a given

period of time (Revised 1996 IPCC Guidelines)

Emission Factor

average emission rate of

a given GHG for a given source, relative to units of activity (Revised 1996 IPCC Guidelines)

1. Activity Data

 Stationary and Mobile Fuel Combustion: Cubic meters (m3), kiloliters (kl) or gigajoules (GJ),

Litres (l) or kiloliters of liquid fuel combusted in stationary or mobile combustion;

 Purchased Electricity: Kilowatt hours (kWh) or megawatt hours (MWh) of

electricity consumed for energy

 Kilometers (km) travelled by a transport vehicle

 Waste: Waste Characterization Analysis Study (WACS), volume of waste

2. Emission Factors are calculated ratios relating GHG emissions to a proxy

measure of activity at an emission source. Examples of emission factors:

 Kilograms (kg) of CO2 per GJ of natural gas combusted

 Kilograms (kg) of CO2 per kiloliters of diesel combusted

 Kilograms (kg) of CO2 per air km travelled

 Kilograms (kg) of CO2 per kWh of electricity consumed

 Kilograms (kg) of CH4 emitted per ha of land cultivated

 Kilograms (kg) of CO2 sequestered per ha of forest
