Remap an ACCU project data frame to the carbondata voluntary- project schema

The carbondata R package exposes Verra, Gold Standard, ACR, and CAR voluntary projects under a unified schema. This function renames ACCU register columns to match, so an analyst can compare ACCU issuance patterns against international voluntary markets on a consistent basis.

Usage

cer_to_carbondata(x)

Arguments

x

A cer_tbl from cer_accu_projects().

Value

A data frame with carbondata-style columns: project_id, project_name, methodology, project_type, country, registry, issued_credits_to_date, retired_credits_to_date.

Details

Schema mapping is lossy: ACCU-specific fields (Chubb flag, permanence period, crediting-period dates) pass through with original names.

try({
  ccy <- cer_accu_projects()
  carb <- cer_to_carbondata(ccy)
  head(carb)
})
options(op)
# }
