what is an ghg inventory program for
What is an GHG Inventory Program for?
  • Meet international obligations and expectations
  • Inform international, national, & local policy making
  • Enhance credibility of national climate policies through timely, transparent, and effective analysis & communication
  • Foster consistent estimation approaches across government & private sector programs
  • Respond to requests for information
  • Champion for high quality & objective inventory information
what is quality
What is quality?
  • Transparency
  • Completeness
  • Comparability
  • Consistency
  • Accuracy

Transparency is the most fundamental. If you do not document, then there is no way to demonstrate any of the other principles have been met.

who cares
Who cares?
  • A wide audience of stakeholders...
    • Decision makers & policy advisors
    • International climate change community
    • Provincial & local agencies
    • The public & interest groups
    • Businesses
    • Scientists
national government
National government
  • Are national inventories verifiable?
  • What are current & projected emissions and removals from key industries?
  • What are the effects of existing or planned policies and measures (including policies that aggravate emissions)?
  • Is there consensus among government agencies and key stakeholders on our emission estimates?
  • What are the relationships between reducing greenhouse gas emissions and other environmental pollutants?
international community
International community
  • What is the your country’s contribution to global emissions and removals?
  • Are your GHG estimates credible and transparent?
  • Is your country meeting its UNFCCC obligations?
businesses ngos
Businesses & NGOs
  • How do we quantify and get credit for activities that reduce emissions or sequester carbon?
  • What activities, industries, companies, or policies have been responsible for significant increases or decreases in GHG emissions or removals?

Scientists

  • What are the priorities for research and measurement?
  • What are the scientific uncertainties in the emission and sink estimates?

inventory management systems should
Inventory management systems should...
  • Ensure inventory processes are in compliance with COP decisions (i.e., Non-Annex I Party National Communications)
  • Define and apply appropriate procedures for collecting, processing, communicating, and archiving inventory data & information
  • Coordinate with relevant ministries, agencies, and other organizations
  • Provide inventory reports regularly
  • Ensure the quality of inventory data

  • Inventory planning
  • Inventory preparation

Inventory planning
  • Establish national inventory agency
  • Assign responsibilities for inventory preparation and management
  • Develop schedule
  • Make arrangements to collect data from statistical agencies, companies, industry associations, etc.
  • Create QA/QC plan
  • Define formal approval process within government
  • Develop review processes
  • Integrate continuous improvement

inventory preparation
Inventory preparation
  • Identify key categories
  • Select methods and emission factors (e.g., GPG decision trees)
  • Collect activity data
  • Manage recalculations
  • Implement QA/QC plan
    • Basic checks should be completed on entire inventory (Tier 1) (see GPG Ch. 8)
    • More in-depth investigations into key sources (Tier 2)
  • Documentation
key categories
Key categories
  • A key category has a significant influence on a country’s total inventory in terms of level or trend in emissions (GPG, Ch.7)
  • A key category may also be determined through a qualitative assessment.
  • A key category is one that is prioritized within the national inventory system
  • In general, countries should focus on key categories for resources and improvements
inventory management
Inventory management
  • Implement inventory review processes (e.g., expert review, public review)
  • Obtain formal approval of final results and report within government
  • Submit report to UNFCCC
  • Make inventory information available to stakeholders and respond to information requests
  • Archive all documentation and results
  • Continuous improvement feedback
uncertainty
Uncertainty
  • Uncertainty analysis is a subjective exercise, as it relies to a large extent on expert judgment
  • Therefore, it is not a valid basis to compare inventories between countries
  • Uncertainty analysis should be used as a way to investigate the quality of your inventory data and identify ways to improve data quality
  • You achieve by communicating with data suppliers (e.g., statistical agencies)

Uncertainty investigations should be integrated within your QA/QC plan!

closing remarks
Closing remarks…
  • A greenhouse gas inventory is more than just a report. It should be viewed as an broader analytical program.
  • A “cookbook” approach to developing a GHG inventory is not practical. There will always be a large and essential need for expert judgment at all levels of the process.
  • A well constructed inventory should include enough documentation to allow readers to understand the underlying assumptions and to reconstruct the calculations.

emission inventory basics
Emission Inventory Basics
  • An emission inventory is an accounting of the amount of air pollutants discharged into the atmosphere. It is generally characterized by the following factors:
    • The chemical or physical identity of the pollutants included
    • The geographic area covered
    • The institutional entities covered
    • The time period over which emissions are estimated
    • The types of activities that cause emissions
inventory agency responsibilities
Inventory Agency Responsibilities
  • A single national entity to be responsible for the overall inventory
  • Arrangements with collaborating entities that contribute data, research, estimate emissions or provide expert reviews
  • Define legal authority to collect and disseminate data necessary for the preparation of the inventory
  • Ensure inventory processes are in compliance with COP decisions
  • Define and apply procedures for collecting data, preparing inventory, communicating results, submitting report, and archiving
  • Liaise among government departments, national agencies,
  • Ensure the implementation of QA/QC
goals
Goals
  • Develop high quality inventory at regular intervals (e.g., annually, every 2-4 years, etc).
    • Resources are focused on the most significant emission sources in the country
