Reconcile an aggregate against the QCMR headline figure

Source: R/reconcile.R
cer_reconcile.Rd

Compares a scalar or data-frame sum against the CER Quarterly Carbon Market Report headline for the same quarter and measure. Warns on absolute percentage gap > 2% (default). Small gaps (sub-1%) are expected because ACCU project registers are retroactively revised between QCMR releases.

Usage

cer_reconcile(value, quarter, measure, sum_column = NULL, warn_pct = 0.02)

Arguments

value

Numeric scalar or data frame. If a data frame, pass sum_column to pick which numeric column to sum.

quarter

Character, e.g. "2024-Q4" or "2023-24".

measure

Character, matching a measure value in cer_qcmr_reference(). For example "accu_cumulative_issuances", "safeguard_covered_emissions_mt", "smc_issuances".

sum_column

Column name to sum when value is a data frame.

warn_pct

Warn if |pct_diff| > this threshold. Default 0.02.

Value

A one-row data frame: measure, quarter, value, reference, diff, pct_diff, unit, source.
