Inventory management system
This document discusses the importance and process of developing a greenhouse gas inventory. It explains that an inventory program is needed to meet international obligations, inform policymaking, and enhance credibility. It outlines key principles of quality like transparency and accuracy. It then describes the typical components of an inventory management system, including planning, preparation, and management. It emphasizes focusing resources on key emission sources and categories.

- 3. 3 What is anGHG 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
- 4. 4 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.
- 5. 5 Who cares? ▪ Awide audience of stakeholders... ▪ Decision makers & policy advisors ▪ International climate change community ▪ Provincial & local agencies ▪ The public & interest groups ▪ Businesses ▪ Scientists
- 6. 6 National government ▪ Arenational 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?
- 7. 7 International community ▪ Whatis the your country’s contribution to global emissions and removals? ▪ Are your GHG estimates credible and transparent? ▪ Is your country meeting its UNFCCC obligations?
- 8. 8 Scientists 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? ▪ What are the priorities for research and measurement? ▪ What are the scientific uncertainties in the emission and sink estimates?

- 12. 12 Inventory planning ▪ Establishnational 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
- 13. 13 Example: U.S. InventorySchedule Submit Inventory to UN April 15thApril - September Gather data and prepare initial estimates Jan - Feb Incorporate public comments Late December Release for public comment Nov - Dec Respond to interagency comments Oct - Nov Expert and interagency review Mid October Prepare draft report
- 14. 14 Inventory preparation ▪ Identifykey 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
- 15. 15 Key categories ▪ Akey 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
- 16. 16 Inventory management ▪ Implementinventory 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
- 17. 17 Uncertainty ▪ Uncertainty analysisis 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!

- 20. 20 Closing remarks… ▪ Agreenhouse 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.

- 23. 23 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
- 24. 24 Inventory Agency Responsibilities ▪ Asingle 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
- 25. 25 Goals Develop highquality inventory at regular intervals (e.g., annually, every 2-4 years, etc). Resources are focused on the most significant emission sources in the country

Editor's Notes
- #2 If you think your job is difficult… This is what folks think of greenhouse gas inventory reports back in the United States.
- #3 Welcome. Suggest trainees to ask questions during presentation.
- #5 <number>
- #10 I call this, we are the center of the universe slide
- #14 <number>
- #23 <number> On this slide, we are attempting to illustrate the complexity of the information web that underlies our system of gathering data from primary producers and key sources, and then the steps the data goes through before we develop a complete accounting of energy use. The blue ovals represent key sources of information, whether it be a federal agency, national lab, research center, or trade association. The white boxes describe the types of data that is being handled. This slide is only portraying energy related data - this is duplicated for every other category. It is unfortunately the case that although other categories may represent smaller portions of our total emissions, the complexity and level of effort may not be proportionate to the size of emissions. Source categories like agricultural soils, waste handling, and industrial sources are very data intensive.
