Historical Global Emissions Inventory 1890-1990

EDGAR-HYDE provides a 100-year record of anthropogenic emissions for eight key pollutants, including CO2 and SO2. The inventory, constructed by the SCIOPS organization, calculates emissions per country and economic sector at 10-year intervals. It was last updated in 1990, integrating data from the EDGAR 2.0 and HYDE databases.

Use Cases

• Analyze trends in CO2 and CH4 emissions from fossil fuel combustion and industrial processes over a century.
• Model the historical spatial distribution of SO2 and NOx emissions using the 1-degree gridded data for atmospheric studies.
• Assess the relative contributions of source categories like agricultural land and deforestation to N2O and NH3 emissions.
• Compare regional emissions from biofuel combustion and savanna burning for environmental impact assessments.

Strengths

• Covers a 100-year temporal range from 1890 to 1990.
• Includes emissions data for eight distinct chemical species.
• Provides emissions calculated per country and for 10 specific source categories.
• Offers data interpolated onto a consistent 1-degree by 1-degree global grid.

Limitations

• Emissions are calculated only at 10-year intervals, not annually.
• The dataset ends in 1990 and may be temporally stale for contemporary analysis.
• Biomass-burning estimates were added using a described 'simple and transparent' approach, which may lack detail.
