OpenIO v2.4

International imports updated

The origin of the imports was determined relying on the global market for the commodity, determined through Exiobase. For example, cars were mainly coming from China, because China is the biggest car producer.

Now, international trade data were added to determine the actual origin of imports. For example, now the biggest exporter of cars to Canada is now the US, as it should be.

Biogenic carbon estimated

The physical flow account used for GHG emissions follow the SEEA guidelines (System of Environmental Economic Accounting) which does not differentiate between fossil and biogenic carbon. To avoid overestimating, we rely on Exiobase biogenic carbon emission levels (which probably stem from the natioral inventory report instead of the physical flow accounts) to estimate the distribution between fossil and biogenic CO2 in each of the 492 sectors of openIO. One notable exception: the final demand, so far we cannot find external data to remove emissions from burning biomass at home or from cars operating with biofuels. Direct emissions from households are therefore most probably overestimated.

Better agriculture GHG emissions

The GHG physical flow accounts only provide an aggregated value for Crop and animal production. OpenIO in previous versions thus distributed GHG emissions to sub-sectors following an economic allocation. Now, it relies on Exiobase crop and animal production distribution between the three GHGs covered by openIO (CO2, CH4 and N2O).

Discontinued

With this release, we officially stop supporting the industry by industry format, as well as IOIC classifications outside of the "Detail level".
