EXIOBASE is a global, detailed database that provides Multi-Regional Environmentally Extended Supply-Use Tables (MR-SUT) and Input-Output Tables (MR-IOT). It was created by harmonizing and expanding supply-use tables from many countries and adding estimates of emissions and resource extraction by industry. These national supply-use tables were then connected through trade, resulting in the MR-SUT and, from it, the MR-IOTs. The MR-IOTs can be used to study the environmental impacts linked to the final consumption of different product groups. In EXIOBASE, emission factors are expressed in basic prices. A basic price is the cost set by a producer for a product or service before any additional charges, such as taxes or transport costs (known as tax and transport margins), are added.
