4.1 Reporting Emissions Data
To enter GHG emissions data, the reporter will input numerical
values (in units of tonnes) for the emission sources occurring at
the facility (up to eight digits in front of the decimal point and
up to four digits after the decimal point can be entered). The
quantity of emissions in CO2 equivalent units will be
automatically calculated by the EDR system.
A not applicable (N/A) box will be available for each emission
source category and gas listed, and the reporter may select this box
only in those cases where:
- the emission source or emission type does not occur at the
facility; or
- the emissions from a given source are not estimated due to the
unavailability of data.
If a reporter has calculated the emissions for a given category
or gas type and the emissions are zero, the reporter is to enter the
digit “0” in the relevant numeric field.

4.2 Carbon Dioxide, Methane and Nitrous Oxide
Emissions
The reporting facility needs to calculate and report its direct
emissions of the three gases CO2, CH4 and
N2O individually. When reporting these emissions, the
reporter is required to disaggregate the emissions by the following
source categories:
- Stationary Fuel Combustion
- Industrial Process
- Venting and Flaring
- Other Fugitive
- Waste and Wastewater
- On-site Transportation
Additional information on each of these categories is provided in
the following subsections.
4.2.1 Stationary Fuel Combustion
Emissions
This category includes emissions from non- vehicular combustion
sources occurring at the facility, where the fuel is burned for the
purpose of producing energy (e.g. to generate electricity, heat or
steam). This includes on-site waste incineration if the waste is
combusted for energy. Emissions from waste incineration used as a
disposal method are included under the Waste and Wastewater
Emissions category (see section 4.2.5). Special
consideration is needed for CO2 emissions from the
combustion of biomass (see section 4.2.7).
This category of emissions is a common, cross- sector type; it is
likely that most facilities in the various sectors have on-site
operations that produce this type of emissions.
4.2.2 Industrial Process
Emissions
This category refers to emissions from an industrial process
involving chemical reactions other than combustion and where the
primary purpose of the industrial process is not energy production.
Examples of industrial processes that represent sources of this
category of emissions include mineral production (e.g. cement,
lime), metal production (e.g. iron and steel, aluminium) and
chemical production (e.g. adipic acid, nitric acid).
This category of emissions is expected to be more unique to
specific sectors and to specific facilities in a given sector,
depending on the operations performed at the facility.
Note: In instances where industrial
process emissions are produced in combination with emissions from
fuel combusted for energy purposes, the emissions are to be
categorized according to the primary purpose of the activity –
either “energy” or “process.16
If the primary purpose is the generation of energy, the emissions
are included under Stationary Fuel Combustion Emissions, and if it
is process-related, the emissions are included under Industrial
Process Emissions. The reduction of iron in a blast furnace through
the oxidation of coke is an example. Invariably, the heat released
is used within the process or for other energy needs; however, in
this case, since the primary purpose of coke oxidation is to produce
pig iron, the emissions are categorized as Industrial Process
Emissions.
4.2.3 Venting and Flaring Emissions
Venting emissions are defined as the intentional release to the
atmosphere of a waste gas or liquid stream. These include, but are
not limited to, emissions of casing gas, associated (or solution)
gas, treater, stabilizer, dehydrator off- gas and blanket gas as
well as emissions from pneumatic devices that use natural gas as a
driver, compressor start-up, pipeline and other blowdowns, and
metering and regulation station control loops.
Flaring emissions are defined as intentional releases of gases
from industrial activities from the controlled combustion of a gas
and/or liquid stream produced on site not for the purpose of
producing energy. They may arise from waste petroleum incineration,
hazardous emission prevention systems (whether in pilot or active
mode), well testing, natural gas gathering systems, processing plant
operations, crude oil production, pipeline operations, petroleum
refining as well as chemical fertilizer and steel production.
In general, venting and flaring emissions are a result of the
handling or processing of fuel in the fossil fuel industries.
Note: Flaring of landfill gas is to be
accounted for under the Waste and Wastewater Emissions category (see
section 4.2.5).
4.2.4 Other Fugitive Emissions
Other fugitive emissions are defined as intentional or
unintentional (e.g. leaks) releases of gases from industrial
activities, other than those that fall under Venting and Flaring
Emissions described above. In general, other fugitive emissions are
a result of the handling or processing of fuel in the fossil fuel
industries. In particular, they may arise from the production,
processing, transmission, storage and use of solid, liquid or
gaseous fuels. Examples include leakage from natural gas
transmission lines and processing plants, accidental release from
oil and gas wells, and releases from the mining and handling of
coal.
4.2.5 Waste and Wastewater Emissions
This category refers to any direct emissions from on-site (i.e.
at the facility) disposal of waste and waste or wastewater
treatment. Sources of emissions from on-site waste disposal and
waste or wastewater treatment at a facility may include landfilling
of solid waste, flaring of landfill gas, treatment of liquid waste
and waste incineration. GHG emissions from waste-to-energy
conversion, where waste material is used directly as fuel or
converted into fuel, must be calculated and reported under
Stationary Fuel Combustion Emissions. There are emissions of
CO2, CH4 and N2O from waste
disposal, and special consideration is necessary for CO2
emissions originating from biomass materials in waste (see section 4.2.7).
4.2.6 On-site Transportation Emissions
This category refers to any direct emissions of CO2,
CH4 and N2O resulting from fuel combustion in
machinery used for the on-site (i.e. at the facility) transportation
of products and material integral to the production process. The
terminology “integral to the production process” means transporting
raw or intermediate products and materials within the production
process. Examples of such activities may include:
- equipment used at a steel mill to move molten metal to
different stages in the steel production process;
- equipment used at oil sands operations to mine and/or move oil
sand or other materials to subsequent on-site processes (e.g.
crushing, extraction); and
- equipment used at above- or below-ground mining operations to
mine and/or move mined materials or other intermediate products or
materials to different on-site production processes.
4.2.7 Memo Item —
CO2 Emissions from Biomass
(i) CO2 Emissions from Combustion of
Biomass
The facility may use biomass materials as a fuel source in its
on-site combustion processes. The reporting facility is to report
the CO2 emissions from the combustion of biomass fuels,
but these are not to be included in the emission totals for the
facility. The reporter is to record these emissions separately in
the EDR application (as a memo item only). For the CH4
and N2O emissions resulting from the combustion of
biomass fuels, the reporter is to include these emissions
in the facility totals.
Similarly, for waste incineration processes that may be occurring
at the facility, the waste stream may be composed of organic (or
biomass) materials and fossil fuel-based carbon materials (e.g.
plastics, rubber, liquid solvents, waste oil). The CO2
emissions from the biomass portion being incinerated are to be
reported separately in the GHG report as a memo item (not included
in the CO2 emission totals), whereas the CO2
emissions resulting from incineration of the fossil fuel-based
fraction are included in the facility totals.
As a further example of combustion of biomass materials, in the
case of flaring of landfill gas, the CO2 emissions
produced from this combustion process are to be recorded as a memo
item (not included in the emission totals), since landfill gas is
considered a biomass material. However, the CH4 and
N2O emissions from this process are to be included in the
emission totals and are to be reported under the Waste and
Wastewater Emissions category.
(ii) CO2 Emissions from Non-combustion of
Biomass
Waste disposal can produce substantial amounts of CO2,
a result of aerobic decomposition of organic (or biomass) material
in the waste stream. The reporter is not required to report these
CO2 emissions. (Reported and counted emissions are to
include CH4 and N2O).

4.3 Hydrofluorocarbon, Perfluorocarbon and
Sulphur Hexafluoride Emissions
The reporting facility also needs to calculate and report its
direct emissions of the HFC and PFC gas species listed in Table 1
and the gas SF6, if the facility emits these GHGs from
industrial processes and industrial product use.
HFC, PFC and SF6 emissions from industrial processes
are described as emissions resulting from a chemical or physical
transforming of material, such as HFCs and PFCs used as foam-
blowing agents and PFC emissions from anode effects in primary
aluminium smelting.
Industrial product use is described as the use of a product for
an industrial process that does not react in the process, such as
SF6 and HFCs used in the magnesium industry as a cover
gas. Use of SF6 in electrical equipment (e.g.
gas-insulated switchgears, circuit breakers) is also considered as
an industrial product use.
The following subsections provide additional details on these
GHGs and possible sources of such emissions.
4.3.1 Hydrofluorocarbons
(i) Overview
HFCs are a series of synthetic gases containing carbon, hydrogen
and fluorine (see Table 1 for the
individual HFC species). While HFCs are emitted in small quantities,
they have disproportionate effects as a result of long atmospheric
lifetimes, which in turn lead to large GWPs. The HFC species have
100- year GWPs ranging from 140 to as high as 11 700. The use of
HFCs is expected to grow substantially as a result of the phasing
out of various ozone- depleting substances (IPCC/OECD/IEA, 1997).
HFCs are not included under the Montreal Protocol because they are
not considered to be ozone- depleting substances.
(ii) Sources
The main sources of HFC emissions from industrial processes and
industrial product use include emissions arising from foam blowing
and the use of HFCs as a cover gas in metal production.
Emissions of HFCs from other applications, such as refrigeration,
air conditioning, propellants in aerosols, fire extinguishers and
solvents, are not considered industrial process or industrial
product use emissions under the mandatory reporting of GHG emissions
and therefore are not to be reported.
4.3.2 Perfluorocarbons
(i) Overview
PFCs are a family of industrial gases, and they are to be
reported by individual PFC gas species (see Table 1). Total emissions of PFCs are
relatively low; however, they are potent GHGs, with 100-year GWPs
ranging between 6500 and 9200. PFCs are not ozone-depleting
substances, so they are not included under the Montreal Protocol
(IPCC/OECD/ IEA, 1997).
(ii) Sources
The main sources of PFC emissions from industrial processes and
industrial product use are attributed to two areas — aluminium
production and foam blowing. PFC emissions are an undesirable by-
product of aluminium production, while PFCs are purchased and used
as foam-blowing agents.
Emissions of PFCs from other applications, such as refrigeration,
air conditioning, semiconductor manufacturing, solvents, aerosols
and fire extinguishing, are not considered industrial process or
industrial product use emissions under the mandatory reporting of
GHG emissions and therefore are not to be reported.
4.3.3 Sulphur
Hexafluoride
(i) Overview
SF6 is a synthetic gas with chemical properties that
render it relatively inert, which makes it a preferred choice in
various industrial applications. It is a particularly potent GHG,
with a 100-year GWP of 23 900 and an estimated lifetime of about
3200 years (IPCC/OECD/IEA, 1997).
(ii) Sources
The main sources of SF6 emissions from industrial
processes and industrial product use include SF6 used as
a cover gas in magnesium smelting and casting as well as for special
foundry products in the aluminium industry. Use of SF6 as
an insulating gas in electrical equipment (e.g. gas-insulated
switchgear, circuit breakers) is also considered as an industrial
product use.
Emissions of SF6 from other applications, such as fire
suppression and explosion protection, leak detection and various
electronic applications, are not considered industrial process or
industrial product use emissions under the mandatory reporting of
GHG emissions and therefore are not to be reported.

4.4 Estimation Methods
The reporting facility must identify and report the type of
estimation method or methods used to determine the quantities of
emissions reported. Such methods include monitoring or direct
measurement, mass balance, emission factors and engineering
estimates.
Reporters are reminded of the legal requirement to keep copies of
the information submitted, together with any calculations,
measurements and other data on which the information is based.
For Phase 1, there are no specific protocols to define how
reporters must calculate their GHG emissions. However, where
reasonable, reporters should use methods that are consistent with
the methodologies approved by the UNFCCC and developed by the IPCC.
Refer to sections 2.1-2.4 for background information and a more
complete description of the flexibility allotted to reporters in
their estimation procedures. If the reporter wishes to obtain
further details on the IPCC methodologies, Table
2 presents specific references to the relevant sections of the
IPCC Guidelines and the Good Practice Guidance for the emission
sources subject to reporting.
