Environment Counts | Satellite-based emissions inventory raises estimate of annual global sulfur dioxide emissions by upto 12 percent :
Existing inventories of sulfur dioxide emissions are derived from self-reported national statistics with varying quality. A new satellite-based sulfur dioxide (SO2) detection technology has been used to create a global emission inventory for SO2 that is independent of conventional bottom-up information sources.
The study finds that of the 500 or so large sources in the satellite-drived inventory, nearly 40 are not captured in leading conventional inventories. Most of the missing sources are found in the developing world. Together their emissions represent roughly 6â€“12% of global anthropogenic sulfur dioxide emissions.
