Fossil-fuel CO2 emission estimates at 1x1 km in Tokyo

Click Here to Download Click Here to Download

The product includes annual total fossil-fuel CO2 emissions from point, line, and area sources at 1x1 km spatial resolution in Tokyo in 2014. The emissions were estimated using a bottom-up approach with detailed activity data including the operating ratios of power plants, load factors of vessels, fossil-carbon contents of waste, emission factors for fossil-fueled power generation, aircraft movements, navigation, and combustion processes.
