Berkeley Voluntary Registry Offsets Database

Fetches the Berkeley GSPP Voluntary Registry Offsets Database, an aggregator of Verra, Gold Standard, ACR, CAR, and ART TREES project registrations and issuances. Released bimonthly under CC BY 4.0.

Usage

co2_vrod(sheet = "PROJECTS", refresh = FALSE)

Arguments

sheet

Character. Which workbook sheet to read. "PROJECTS" (default) is the project register and the only sheet that is a tidy table: it is parsed properly, with the header row located and tally rows dropped. The workbook's other sheets are charts, documentation, and drop-down lookups rather than datasets; naming one reads it verbatim and you get whatever layout it happens to have.

refresh

Re-download? Default FALSE. Each release has a date-stamped filename; the package scrapes the landing page to find the latest release on each call unless a cached copy exists.

Value

A data frame of project-level data.
