EU ETS verified emissions

Source: R/euets.R
co2_euets_emissions.Rd

Fetches annual verified greenhouse-gas emissions for installations covered by the EU Emissions Trading System, from the DG CLIMA Union Registry bulk download. Coverage: ~10,000 stationary installations plus ~1,500 aircraft operators across the EU, EEA, and linked Swiss ETS. Emissions data from 2005 onwards; annual files published each April for the prior compliance year.

Usage

co2_euets_emissions(
  country = NULL,
  year = NULL,
  file_year = NULL,
  scheme = c("ets1", "ets2", "all"),
  refresh = FALSE
)

Arguments

country

Optional character vector of two-letter registry codes to filter (e.g. c("DE", "FR", "PL")).

year

Optional integer vector of emissions years. When NULL, returns all years in the latest published file. Note that the file year (e.g. "2025") refers to publication year; emissions data covers calendar years up to publication year -1.

file_year

Publication year of the DG CLIMA file to use. Default is the latest year available in the package (see co2_euets_files()).

scheme

Which trading system to return. "ets1" (default) is the original EU ETS: power, industry, and aviation installations. "ets2" is the separate buildings, road transport, and small industry system that began reporting for compliance year 2024, which DG CLIMA publishes in the same file as one aggregate account per member state. "all" returns both, and is rarely what you want: the two are different systems on different accounting bases, so summing them together double-counts (ETS2 accounts added 981 Mt to the 2024 file, about 45% of the reported total).

refresh

Logical. Re-download? Default FALSE.

Value

A data frame with columns country, installation_id, installation_name, activity, scheme, year, verified_emissions_tco2e, allocation_eua.
