OperationId:environment_co2_country_iso3

Returns every column in the OWID CO2 bundle for one ISO 3166-1 alpha-3 coded country. Covers CO2 totals, CO2 by source (coal, oil, gas, cement, flaring, other, land-use change), consumption-based CO2, cumulative CO2, share-of-global contributions, methane, nitrous oxide, total greenhouse gases, temperature-change contributions, population, GDP, and primary energy. Annual cadence. Early rows (pre-1900) carry only cement and basic CO2 columns; later decades populate progressively more columns as upstream measurement starts. For regional aggregates (World, EU27, OECD, Africa) use /world or /region/{region} - ISO3 coverage is for sovereign countries only.
