ASC 818-20 governs the accounting for environmental credits (e.g., emissions allowances, carbon offsets, renewable energy certificates, RINs). An environmental credit is recognized as an asset only if it is probable it will be used to settle an environmental credit obligation, transferred in an exchange transaction, or used in a nonreciprocal transfer; otherwise the cost is expensed as incurred and can never later be capitalized. Credits recognized as assets are classified as compliance credits (not remeasured) or noncompliance credits (tested for impairment each reporting date, with an optional fair value policy election by class for eligible credits).
Key points (7)
- An environmental credit is recognized as an asset only if it is probable it will be used to settle an environmental credit obligation, transferred in an exchange transaction, or used in a nonreciprocal transfer; all other credits (and nonrefundable deposits for such credits) are expensed as costs are incurred and may not be added to the carrying amount of another asset (818-20-25-1; 25-3).
- Credits recognized as assets are classified as compliance environmental credits if probable of being used to settle an environmental credit obligation, and as noncompliance environmental credits otherwise; the probability assessment is collective and need not be made credit by credit (818-20-25-2; 25-5; 55-2; 55-4).
- Initial measurement: internally generated credits and credits granted by a regulator or its designee are measured at transaction costs incurred, if any (zero if none); credits obtained in a transaction measured under another Topic follow that Topic; all others are measured at cost under 805-50-30-1 through 30-4 (818-20-30-1 through 30-3; 55-5).
- Compliance environmental credits are not subsequently remeasured; noncompliance environmental credits are tested for impairment at each reporting date, with loss equal to the excess of carrying value over fair value and reversal prohibited; no credit is amortized (818-20-35-3; 35-4; 35-6).
- Similar credits are subsequently measured using average cost, FIFO, or specific identification, applied separately to compliance and noncompliance credits (818-20-35-2).
- An entity may elect, by class, to measure eligible noncompliance credits (obtained in an exchange transaction, a nonreciprocal transfer other than a regulator grant, or a business combination) at fair value through earnings; that measurement continues until derecognition, even if later reclassified as compliance credits, and a change to the policy is applied prospectively with a cumulative-effect adjustment to retained earnings (818-20-35-7 through 35-10; 55-7; 55-8).
- Derecognition follows Subtopic 610-20 (or Topic 606 for contracts with customers); if it is no longer probable a credit will be used, transferred, or nonreciprocally transferred, it is derecognized through earnings and can never be re-recognized as an asset (818-20-40-1 through 40-3).
For students. This is new guidance (effective for fiscal years beginning after Dec. 16, 2027 for public entities) creating a distinct asset model for carbon credits and allowances. The classic trap: regulator-granted and internally generated credits are measured at transaction costs (often zero) and are never eligible for the fair value election, and once a credit fails the probable test it is expensed permanently — no later capitalization or impairment reversal.
