Carbon markets create tradable rights and obligations tied to greenhouse-gas emissions. Entities may receive allowances for free, buy them, sell them, or use them to settle compliance obligations that arise as emissions are generated. Under IFRS (IAS 38, IAS 37, IAS 2, IFRS 9, IAS 20) and US GAAP (ASC 350, ASC 450, ASC 815, ASC 606/610-20 by analogy), practice focuses on: (1) what the allowance is (intangible inventory vs financial asset), (2) how the emission obligation is measured, and (3) how free allocations and sales are presented. Policy choices must be applied consistently and disclosed clearly.

How emissions trading schemes create assets and obligations.
Cap-and-trade programs (e.g., EU ETS, UK ETS, regional schemes) issue allowances that permit the holder to emit a specified quantity (often one ton of CO₂-e). Companies generate emission obligations as they operate, and must surrender allowances to regulators periodically. Allowances can be granted for free, purchased, banked, sold, or settled at compliance dates. This creates a moving mix of intangible assets (allowances held) and a provision (the compliance liability) tied to actual emissions.
In voluntary markets, credits (VERs) are often acquired for offsetting or resale. The accounting follows their intended use: consumption for compliance/offset, or trading for profit.

IFRS models for allowances and the compliance obligation.
Under IFRS, there is no single dedicated standard; entities apply existing literature consistently:
1) Measurement of allowances held.
IAS 38 (Intangible assets) is commonly applied when allowances are held for own use (compliance/offset). Subsequent measurement is cost less impairment. If an active market exists, a revaluation model may be elected (policy choice) with changes through OCI for the intangible class.
IAS 2 (Inventory) may be applied when the business model is broker-trader; measurement is typically fair value less costs to sell with changes in profit or loss.
IFRS 9 applies when instruments meet the financial asset definition (e.g., forward contracts, options on allowances).
2) Recognition of the emission obligation (provision).
Under IAS 37, a provision arises as emissions occur (present obligation, reliable estimate, probable outflow).
Measure at the best estimate of the allowances that will be surrendered or the expected cash to acquire missing allowances. Many entities use current market prices on the reporting date for the uncovered portion.
3) Accounting for free allocations (government assistance).Two prevalent IFRS policy approaches (apply consistently):
Deferred-income approach (IAS 20 analogue): recognize the free allowances at fair value with a deferred grant released to income systematically as emissions occur.
Nil-cost approach: recognize free allowances at nil cost; no grant income; recognize the provision as emissions accumulate and derecognize allowances at their carrying amount on surrender.
Illustrative entries (IFRS — compliance user, deferred-income policy):On receipt of free allowances (FV 1,200,000)
Debit: Emission Allowances (Intangible) 1,200,000
Credit: Deferred Grant Income 1,200,000
As emissions occur (recognize obligation for period, 900,000)
Debit: Emissions Expense 900,000
Credit: Provision for Emissions 900,000
Amortize grant to match emissions (for 900,000 usage)
Debit: Deferred Grant Income 900,000
Credit: Other Income (Grant) 900,000
On surrender of allowances for the period (carrying amount 900,000)
Debit: Provision for Emissions 900,000
Credit: Emission Allowances (Intangible) 900,000
Illustrative entries (IFRS — purchased allowances for compliance):Purchase
Debit: Emission Allowances (Intangible) 600,000
Credit: Cash 600,000
Period-end obligation exceeds allowances on hand; top-up at market
Debit: Emissions Expense 250,000
Credit: Provision for Emissions 250,000
Broker-trader (IAS 2 at FVLCTS): remeasure inventory each period through P&L; no grant model.

US GAAP approaches for allowances and obligations.
US GAAP lacks a comprehensive Topic for compliance schemes; practice relies on analogy and consistent policies:
1) Allowances held.
Often treated as indefinite-lived intangible assets under ASC 350 at cost, tested for impairment when indicators exist.
Entities active in trading may treat allowances akin to inventory at the lower of cost and net realizable value, or mark-to-market if accounted for as commodities/derivatives (when contracts meet ASC 815).
Forward purchases/sales, options, and swaps referencing allowances are analyzed under ASC 815 for derivative accounting.
2) Emission obligation.
Recognized as a contingent liability under ASC 450 as emissions occur; measured at the best estimate (often current market price for shortfall allowances to be purchased).
No general grant standard for for-profits; entities may analogize to IAS 20 or present other income when free allocations are received and conditions are met, applied consistently and disclosed.
Illustrative entries (US GAAP — cost model, free allocations at nil cost):On receipt of free allowances (at cost = 0)
No entry (or disclose quantity and program terms).
Recognize obligation for period (shortfall at market 700,000)
Debit: Emissions Expense 700,000
Credit: Accrued Emissions Liability 700,000
Purchase and surrender of allowances
Debit: Emissions Allowances (Intangible) 700,000
Credit: Cash 700,000
Debit: Accrued Emissions Liability 700,000
Credit: Emissions Allowances (Intangible) 700,000
Trading activity (GAAP): gains/losses on sale of allowances generally in other income/expense; derivative contracts follow ASC 815 with fair value through earnings.

Comparative table: IFRS vs US GAAP.
Aspect | IFRS (IAS 38 / IAS 37 / IAS 2 / IAS 20) | US GAAP (ASC 350 / ASC 450 / ASC 815) |
Allowances for own use | Intangible at cost (option to revalue if active market); impairment under IAS 36. | Intangible at cost; indefinite-lived, test for impairment when indicators arise. |
Broker-trader inventory | IAS 2 at FVLCTS through P&L. | Policy-based; inventory/commodity or derivative accounting; fair value if under ASC 815. |
Emission obligation | IAS 37 provision recognized as emissions occur; measured at best estimate (often market). | ASC 450 liability recognized as emissions occur; best estimate (often market). |
Free allocations | Policy choice: deferred-income grant (IAS 20) or nil-cost; apply consistently. | No unified rule; common policies: nil-cost with no income, or analogize to grant income; disclose policy. |
Derivatives on allowances | IFRS 9 at FVTPL. | ASC 815 at fair value through earnings. |
Presentation emphasis | Separate line for provision; movement in allowances; grant income schedule. | Liability accruals; gains/losses on sales; derivative fair-value effects; policy disclosures. |

Impact on financial performance and ratios.
Carbon accounting affects operating costs, EBITDA, and working capital. Under the deferred-income model, grant income offsets compliance costs and smooths EBITDA; under nil-cost, expenses are more visible as provisions rise with emissions. Price volatility in allowance markets can shift margins for broker-traders (fair value through P&L) and alter the expected cash outflows for compliance users, impacting liquidity ratios and forecast accuracy.
Analysts evaluate:
The coverage ratio (allowances held vs expected emissions).
Sensitivity to carbon price changes.
The magnitude and policy of grant recognition.
The consistency of measurement across periods and schemes.
·····
.....
Operational considerations.
Finance teams must integrate emissions data systems with the general ledger to accrue provisions as activity occurs. Treasury should manage hedging or forward purchases to lock carbon costs. Policies for allowance classification, grant accounting, and derivative use should be documented, approved by governance bodies, and applied consistently. Internal controls should track units (quantities), vintage years, expiry, and registry movements to avoid misstatements at surrender dates.
Clear, consistent accounting enables stakeholders to understand how carbon policy translates into cash economics, operational incentives, and reported profitability.
