### Background — current treatment and ISWGNA recommendation
- Under the 2008 SNA, emission permits (EP) are considered as "D29 other taxes on production" since EPs "do not involve the use of a natural 'asset'".
- Tax revenue is recorded as sales of EPs at time of surrender.
- The ISWGNA requested further guidance because the 2008 SNA treatment "does not fully articulate all the dimensions of tradeable emission permits".
- An OECD/Eurostat Task Force produced guidance in the "Final Report October 2010".
- The ISWGNA recommended the split asset approach (described in SNA News and Notes numbers 30/31 and 32/33).

### Practical challenges in implementing the split-asset approach
- Classification of a prepaid tax: "Is the classification of a prepaid tax consistent with permit holders other than non-financial corporations?"
- Cross-border trading: "How to deal with cross-border trading of permits and the resultant discrepancy between government revenue from auctions and the subsequent surrender of permits?"
- Free allocation: "How to treat permits which are freely given away by governments?"
- Valuation timing: "What is the value (tax) of the EP – at original issuance or surrender value?"
- The SNA Wellbeing and Sustainability Task Team was asked to examine recommendations and propose alternatives balancing conceptual alignment, pragmatism, consistency, and visibility of transactions, other flows and stocks.

### Alternate recording treatments (enumerated options)
- Option 1. Emission Permits as non-produced non-financial assets (contracts, leases and licenses right to use)
- Option 2. Emission Permits recorded as a resource lease (financial asset), with resource rent recorded at surrender.
- Option 3. Emission Permits recorded as Contracts, Leases, Licenses with taxes on Production recorded at Auction
- Option 4a. Emission Permits recorded as Financial Assets with taxes on production recorded at surrender (issuance value)
- Option 4b. Emission Permits recorded as Financial Assets with taxes on production recorded at surrender (market value)
- Option 5. Emission Permits recorded as split assets, with taxes on production recorded at surrender (current task force recommendation)

### Outcome of AEG and BOPCOM consultation
- General agreement favored Option 4, specifically Option 4a:
  - Classification as accounts receivable (pre-paid taxes) / accounts payable.
  - Taxes on production should be valued at the issuance price recorded at surrender.
- BOPCOM consultation confirmed AEG preference for Option 4a; two members preferred Option 1.
- Unresolved issues identified:
  - Treatment of changes in the market value of tradeable emission permits.
  - Treatment of emission permits issued freely.
  - Whether emission permits are best characterized as debt securities or other assets/liabilities.
  - Practical considerations for multi-country emission permit schemes.
- Consensus that no ideal reflection exists in the standards; a compromise is needed.

### Editorial note and the Option 4(a)* alternative
- Editorial Teams for BPM6 and the 2008 SNA prepared a short note examining feasibility of implementing the recommended option.
- Option 4(a)* proposed to address consistency and recording issues:
  - With Option 4(a), transactions in emission permits at market prices would be immediately revalued back to issuance price in the revaluation account, creating inconsistencies with corporate recording.
  - Option 4(a)* instead creates a new non-produced non-financial asset when transaction price differs from issuance price via the other changes in volume account; this asset is extinguished upon surrender via the other changes in volume account (the split asset approach).
- Both approaches have limitations; a final decision awaited a workshop to review conceptual and practical considerations.

### Workshop objectives, findings, and data challenges
- Workshop objective: Discuss data sources and challenges for estimating emission permits and whether other practical and conceptual options could be implemented as outlined in the guidance note.
- Workshop contributions:
  - Three country presentations, a joint presentation from Eurostat and ECB, and an IMF presentation on global consultation questionnaire results.
  - Presentations highlighted challenges for compilers due to data availability and diverse, changing emission schemes.
- Key practical points for macroeconomic statistics:
  - Compilers need to adjust methodologies and assumptions for time of recording, alignment, valuation and other adjustments.
  - Permits are issued and bought on a particular date, but emissions occur later; countries try to implement an accrual adjustment to align government revenue with emissions.
  - Adjustments are also made to align corporate surplus (expenses) with government revenue.
  - Special treatment considerations for permits provided freely and other adjustments.

### Global consultation questionnaire — participation and data availability
- Questionnaire consisted of 15 questions.
- Total respondents: 70.
- Respondents indicating estimates for emission permits are currently available in National Accounts or Balance of Payments programs: 50 respondents.
- Data availability findings:
  - Government revenue at issuance cost is collected predominately from auctions; the issuance price is known in most cases, but post-issuance market price for a particular permit is a challenge.
  - The number of EPs issued freely and recipients is generally known.
  - Number of surrendered permits and the institutional sector surrendering the permit is available for 48 percent of respondents.
  - Issuance price and market value of the surrendered permit are not available from current data sources for many respondents.
  - Corporate financial statement information on purchases, sales and holdings of EPs is limited: "Only a third of respondents reported that they could collect information on the purchases and sales of EPs and of holdings (assets)."
  - Repository data is available for a limited number of economies.
- Feasibility of experimental estimates:
  - For most respondents, producing experimental estimates in line with the recommended options is not possible due to data availability and resource constraints.
  - Denmark and New Zealand have produced estimates based on the proposed options.

### Summary and way forward
- Data gaps create practical and conceptual measurement issues for EPs in macroeconomic statistics, especially for cross-border transactions.
- Eurostat proposed an alternative recording treatment to overcome several BOP recording issues; the proposal "is by no means ideal, however, warrants further review."
- The Eurostat proposal will be reviewed to ensure "sufficient justification, visibility and consistency."
- Workshop organizers together with the SNA and BOP lead editors will summarize workshop findings for further consideration.
