Global Mercury Emissions
EDGAR v8.1
Introduction
EDGARv8.1 provides emissions not only for the greenhouse gases and air pollutants per sector and country but also for toxic pollutants such as mercury.
EDGARv8.1_toxHg includes:
Total mercury (Hg)
and mercury species:
Gaseous elemental mercury (Hg0; Hg_G)
Gaseous oxidised mercury (Hg2+; Hg_D)
Particle-bound mercury (Hg-P; Hg_P)
Emissions from large scale biomass burning with Savannah burning, forest fires, and sources and sinks from land-use, land-use change and forestry (LULUCF) are excluded.
For the energy related sectors the activity data are primarily based on IEA data from IEA (2022) World Energy Balances, (www.iea.org), all rights reserved, as modified by Joint Research Centre, European Commission, whereas the activity data for the agricultural sectors originate primarily from FAO (2022) (https://www.fao.org/faostat). United States Geological Survey (USGS), UNFCCC and World Steel Association (worldsteel) recent statistics are also used for activity data. The emissions from Artisanal Small Scale Gold Mining (ASGM) sector were updated based on information from publicly available reports and scientific literature; it is foreseen a refinement of these emissions based on the information from official national reporting to the Minamata Convention on Mercury in the framework of the First Effectiveness Evaluation. Additional information can be found in Muntean et al. (2025, in preparation).
Compared to the previous EDGAR version, v4.tox2, the following major updates have been included:
Update of activity data up to 2022
Updates of technology penetration and abatement measures for power generation sector
New spatial proxies as described in Crippa et al. (2024).
Time series (1970-2022)
For each substance, emission timeseries (1970-2022) by sector and country are provided in an overview table (.xls).
Notes: Emission country totals are expressed in kt substance / year. The IPCC 1996 and 2006 codes are used for specification of the sectors. The MINAMATA worksheet provides the aggregation of emissions with specification of the sectors based on the recommendations of Minamata Convention.

EDGAR Hg_D (Hg_D_1970_2022_v2.zip)
EDGAR Hg_G (Hg_G_1970_2022_v2.zip)
EDGAR Hg_P (Hg_P_1970_2022_v2.zip)
Monthly time series (2000-2022)
For each substance, monthly emission timeseries (2000-2022) by sector and country are provided in an overview table (.xls).
Notes: Emission country totals are expressed in kt substance / year. The IPCC 1996 and 2006 codes are used for specification of the sectors.
EDGAR Hg (Hg_m_2000_2022_v2.zip)
EDGAR Hg_D (Hg_D_m_2000_2022_v2.zip)
EDGAR Hg_G (Hg_G_m_2000_2022_v2.zip)
EDGAR Hg_P (Hg_P_m_2000_2022_v2.zip)
Annual gridmaps (1970-2022)
For each substance annual gridmaps (1970-2022) are provided.
Notes: Emission gridmaps are expressed in t substance / 0.1degree x 0.1degree / year for the emi .txt and .nc files and in kg substance /m2 /s for the fluxes .nc files.
Notes: Emission gridmaps are expressed in t substance / 0.1degree x 0.1degree / year for annual emi .txt and .nc files and in kg substance /m2 /s for all the fluxes .nc files. The IPCC 1996 and 2006 codes are used for specification of the sectors.
IPCC 1996:1A1a+1A2 Combustion in power generation and in industry
Monthly emission gridmaps (2000-2022) are provided for all substances and sectors using the temporal distribution profiles described in Crippa et al. (2020).
Sectors definition:
Power Industry - Power and heat generation plants (public & autoproducers)
Industrial combustion - Combustion for industrial manufacturing
Buildings - Small scale non-industrial stationary combustion
Transport - Mobile combustion (road & rail & ship & aviation)
Fuel exploitation - Production, transformation and refining of fuels
Processes - Industrial processes (e.g. emissions from the production of cement, iron and steel, aluminum, chemicals, solvents, etc.)
Waste - Solid waste disposal and waste water treatment
Files format:
Emissions: Mg/month gridmaps at 0.1x0.1degree resolution, .NetCDF file per year, substance and sector is produced including the emissions for the 12 months.
Emission fluxes: kg/m2/s at 0.1x0.1degree resolution, .NetCDF file per year, substance and sector is produced including for each sector the emission fluxes for the 12 months.
