CEDS

The Community Emissions Data System (CEDS) produces consistent estimates of global air emissions species (BC, CO, CO2, NH3, NMVOC, NOx, OC, SO2) over the industrial era (1750 - present) along with CH4 and N2O over recent decades. The system is written in R and uses open-source data (with the exception of the IEA energy statistics which must be purchased from IEA). CEDS is publicly available through an Open Source License.
