Additional environmental extensions for EXIOBASE3 based on USEEEIO

This dataset links the commodity sectors of EXIOBASE3.7 (i.e., pxp version) to additional environmental extensions (e.g., formaldehyde, toluene, acrolein, etc.) based on USEEIOv1.1 extensions. Only environmental extensions that are not present in EXIOBASE were added. This satellite matrix can thus simply be added to the satellite matrix of EXIOBASE without fear of double counting emissions. 1,766 emissions were added.

The dataset also includes a characterization matrix for these additional flows, characterized (for 36 impact categories) using the IMPACT World+ life cycle impact assessment method (Bulle, 2019).

The methodology behind the determination of these additional environmental extensions is described in (Agez et al., 2021), and is more extensively described in (Muller, 2019), albeit in french. In short, we reapply the emission factors from USEEIO (so specific to the US) to all countries of EXIOBASE, which has obvious limitations, but can constitute a good-enough estimation in some cases. (Agez et al., 2021) and (Muller, 2019) for example, show that these additional environmental extensions have a significant effect on some impact categories, namely, ecotoxicity and ozone layer depletion. In other words, normal environmental extensions of EXIOBASE are not equipped to study these impact categories. Other categories are marginally impacted (from 0.5 to 3% increase of the impact when looking at the whole economy's impact).
