The document discusses when accounting guidance could be useful in the NDC (Nationally Determined Contribution) cycle. It suggests accounting guidance may help when countries communicate their NDC, when they track progress during implementation in biennial reports, and after the target period to measure actual achievement against the target. It also presents a diagram showing how accounting guidance could be applied at different stages of the first NDC cycle, including communication of NDCs, implementation, reporting, and accounting for the first NDC. The document raises questions about when in the cycle accounting guidance should be applied and what implications delayed inventory reporting timeframes have for accounting.
