The EDGAR-HTAP project compiled a global emission dataset with annual
inventories for CH4, NMVOC, CO, SO2, NOx, NH3, PM10, PM2.5, BC and OC and covering the
period 2000-2005 using, to the extent possible, official or scientific inventories at the national
or regional scale that are likely to be acceptable for policy makers in each region of the world.

On the global scale the harmonization and improvement of emission inventories is imperative
to get consolidated estimates on formation of global air pollution, and it’s influence on human
health and climate, and so on the benefit of future policies combating these air pollution
aspects. The EDGAR-HTAP project compiled a global emission dataset with annual
inventories for CH4, NMVOC, CO, SO2, NOx, NH3, PM10, PM2.5, BC and OC and covering the
period 2000-2005 using, to the extent possible, official or scientific inventories at the national
or regional scale that are likely to be acceptable for policy makers in each region of the world.
This compilation of different official inventories from EMEP, UNFCCC, EPA for USA, GAINS
for China and REAS was first gap-filled with global emission data of EDGARv4.1. The IPCC
code or UNFCCC’s Common Reporting Format, is used as key for harmonizing the data at
sector level. Next, the resulting emissions by country and sector were allocated to a 0.1º ×
0.1º grid consistently using the EDGARv4.1 proxy data.
The emissions of EDGAR-HTAP were compared with the emission inventory used for the
Representative Concentration Pathways for the next IPCC Assessment Report Differences
between the national inventories and other bottom-up estimates shows the impact of using
higher tier methods and/or country-specific emission factors for compiling a national
inventory. Weaknesses in the official emission reports in the EMEP domain were in particular
found for diffusive sources.
A paradigm of high quality emission inventories consists in scoring high for IPCC’s ‘T-A-C-CC-
A’ (Transparency –Accuracy- Consistency – Comparability –Completeness) principles.
Weaknesses remain in the coherency across borders between different national inventories,
in particular when using different datasets applying different inventorying techniques.
Therefore the EDGAR-HTAP_V1 can not be considered as a consistent global time series
dataset, but can be recommended as a summary with indicative national totals subject to
emission reduction policies.
