FASB finalizes new environmental credit rules

The Financial Accounting Standards Board has issued the first formal accounting standard for environmental credits–carbon offsets and emissions allowances tied to cap-and-trade programmes. Until now, companies operated in a vacuum. GAAP offered no specific direction on how to recognise, measure, or disclose these assets on financial statements, leaving CFOs and auditors to improvise.

This matters because the gap created inconsistency. Some organisations treated offsets as inventory. Others capitalised them as intangible assets. Still others wrote them off immediately. Cap-and-trade schemes now span carbon markets in the EU, California, and beyond; companies trading these allowances needed clarity, not guesswork.

The new standard establishes consistent rules: how to account for credits when purchased, when they're retired or surrendered, and how to record any gains or losses. It narrows the space for creative accounting–and, inadvertently, the space for greenwashing through selective financial reporting. A company can no longer bury offset purchases in obscure line items or defer recognition indefinitely.

But this is accounting standard-setting, not climate action. Finalising how to book a carbon credit doesn't reduce emissions. What it does is force transparency into corporate financial statements, making offset strategy visible to investors, auditors, and regulators. That visibility creates pressure–both to use offsets defensibly and to invest in real emissions reduction instead.

The question now: will this standard be adopted widely, and will regulators in other jurisdictions follow FASB's lead?
