National Greenhouse Gas Inventory
•
Government of Canada’s policy is to comply with international reporting
obligations and support the development of quality inventories
•
Reporting to United Nations Framework Convention on Climate Change
(UNFCCC) for close to two decades
•
National Greenhouse Gas Inventory (consists of the national inventory report
and the common reporting formation tables)
–
Provides a complete national picture of greenhouse gas emissions and removals
for a variety of government and public interest purposes
•
Inventory improvement activities are conducted annually to reduce
uncertainties associated with the estimates based on industry studies,
emission factor research, provincial collaborations, QA/AC procedures, peer
reviews and key category identification.
•
Institutional Arrangements are a Pillar for Data Collection and Quality
Assurance
Page 3 – April 9, 2016
Canada’s GHG Reporting Obligations
• Canada’s National Inventory must be comprehensive, accurate and
verifiable, and must enable reconstruction of estimates from all sources
and sinks.
• National Inventory serves a dual purpose and must meet requirements
of both UNFCCC & Kyoto
• Obligation to use as detailed and up-to-date information as practical to
ensure accurate and meaningful estimates
– “As part of its inventory planning, each Party included in Annex I should consider ways
to improve the quality of activity data, emission factors, methods and other relevant
technical elements of inventories.” FCCC/KP/CMP//2005/8/Add.3 Decision 19 CMP.1
Page 4 – April 9, 2016
UNFCCC Monitoring, Reporting & Review
• Methods
– Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories
(IPCC 1996)
– IPCC Good Practice Guidance and Uncertainty Management in National
Greenhouse Gas Inventories (2000 & 2003 for LULUCF)
• Reporting
– UNFCCC Reporting Guidelines on annual greenhouse gas inventories
(Decision 18/CP.8 & Decision 13/CP.9, 14CP.11)
• Review
– UNFCCC Review Guidelines (Decision 19/CP.8 annex and Decision
12/CP.9)
Page 5 – April 9, 2016
Kyoto Protocol Requirements
•
National System requires additional information under the Kyoto Protocol in
accordance with Articles 5, and 7 of the Protocol
•
By January 1, 2007, need to meet international guidelines related to :
•
The National System (Article 5.1) - the institutional, legal and procedural
arrangements necessary to estimate, verify and report emissions and removals of
greenhouse gases
•
The National Registry (Article 7.4) – the electronic database to account for
transaction of Kyoto units
•
The Annual Inventory Report – (Article 7.1) the reporting of all information required
to assess compliance with the target
Compliance with these guidelines is mandatory to:
• establish an emissions allowance (initial assigned amount)
• participate in the Kyoto Mechanisms
• Avoid a third-party “adjustment” to our emissions estimate
Page 6 – April 9, 2016
Key Reporting and Review Principles
Transparency
▪ Assumptions & methodologies clear
Consistency
▪ All inventory years internally consistent – data/methods
Comparability
▪ IPCC methods and UNFCCC reporting guidelines used
Completeness
▪ All sources/sinks, gases, years included
Accuracy
▪ Promoted via Good Practice Guidance
▪ (QA/QC, Key category identification, uncertainty analysis and
formalized institutional arrangements)
Page 7 – April 9, 2016
Overall Goal - Improving Inventory Quality
National GHG Inventories should be:
• Accurate in the sense that they are neither over- nor
underestimated as far as can be judged,
• Precise in the sense that uncertainties in the estimates should
be reduced as far as practical.

The Energy Sector
Greenhouse Gas Contribution
• In 2006, the Energy Sector accounts for about 80% (583 Mt CO2 eq)
of the national total greenhouse gas emissions (721 Mt CO2 eq.)
• The energy sector includes emissions from:
– Stationary Combustion = 324 Mt CO2 eq.
– Transport = 192 Mt CO2 eq.
– Fugitives = 67 Mt CO2 eq.

Emission Development
• In general, emissions are developed on the basis of fuel
•
•
data.
Almost all fuel data is supplied by Statistics Canada,
Canada’s national statistics agency
There are two major emission categories in the Energy
Sector:
– Combustion sources
▪ Electricity generation, petroleum refining, oil and natural gas
industries, mining, transport, manufacturing industries,
commercial and residential, forestry, agriculture, etc…
– Fugitive sources
▪ Intentional and un-intentional releases from fossil fuel
production, processing, transportation, distribution, storage,
etc…
Page 11 – April 9, 2016
Combustion Sources
Emissions = Σ(Fuel Use x EF)category
Where: EF = Emission Factor = Oxidation Factor per unit fuel

Energy Statistics – Strengths &
Weaknesses
Annual Report on Energy Supply & Demand – Key Source of
Data.
Strengths
•
•
•
•
Captures all energy use including internally produced and consumed energy.
Differentiates between fuels used for industrial processes and fuels used for
electricity.
Differentiates between energy products used for energy purposes and nonfuel use (e.g. natural gas and petroleum coke).
Provides information for a large number of energy commodities at a fine
level of detail.
Weaknesses
•
•
•
•
•
Reliance on information provided by suppliers of energy
Energy consumption data for key sectors such as oil and gas
More industry detail required for key sectors
Alternative and emerging transportation fuels
Little provincial energy consumption data
Page 14 – April 9, 2016
Reporting Emissions in the
Common Reporting Format
• Emissions are reported by
detailed UNFCCC Common
Reporting Format (CRF)
categories, whenever
possible
RESD
Category
to
UNFCCC
Reporting
Category
• In some cases the energy
data is not broken down by
CRF category
–
–
E.g.: Energy data for
industrial electricity
production is not broken
down by the industries in
which it is generated
Therefore must allocate
differently than in CRF

Continuous Improvement Activities
• Reliable, precise energy data is critical to accurate and transparent energy
sector estimates
• Energy section representatives:
– Work directly with Statistics Canada to review annual energy data and assist
in the development of improved data surveys
– Serve on interdepartmental groups to direct work, discuss issues and
improvements
▪ Energy Steering Committee
▪ Energy Working Group
• Energy Balances and the Industrial Consumers of Energy survey (a key
input to the Balances) are jointly supported by Environment Canada and
Natural Resources Canada
– This funding is obtained by means of annual updated memorandum of
understanding
– No long-term funding is in place for this critical energy data
Page 16 – April 9, 2016
Emission Trends
–
Increasing domestic and
foreign demand for oil and
gas contributed to an
increase of 43 Mt CO2 eq.
(34% of Canadian total)
emissions in the fossil fuel
industry.

–
Rising demand for electricity
along with increasing use of
fossil fuels in the generation
mix drove GHG emissions
up by 22 Mt CO2 eq. (17% of
Canadian total) in the
electricity and heat
generation sector
Emissions from the transport
sector has increased by 44
Mt CO2 eq. (34% of
Canadian total) due in parts
to rising use of light duty
gasoline trucks and heavy
duty diesel vehicles
