Called the "Fossil Fuel Data Assimilation System" or FFDAS, this new system developed by scientists of Arizona State University, has been used to reliably estimate CO2 emissions from burning fossil fuels.

The new approach utilises information from satellite feeds, new global database on power plants and national fuel accounts to produce high-resolution planetary maps.

FFDAS will prove to be an exceptionally helpful tool for international and national policymakers and the public to understand to what extent strategies to decrease greenhouse gases are effective.

Kevin Robert Gurney, lead investigator and associate professor at Arizona State University in the US said, “"With this system, we are taking a big step toward creating a global monitoring system for greenhouse gases, something that is needed as the world considers how best to meet greenhouse gas reductions.”

These maps offer an independent, scientific assessment of the earth’s greenhouse gas emissions – something policy-makers can use and the public can understand. Most of the green house emissions are not in a
