Carbon Footprint ISO 14067 extraction from EF 3.1

Question

Hello,

my question is related to the post:

"How can I check the carbon footprint of a product system?"

(I did not want to doublepost, but was not sure if my comment will be seen..)

Can I ask how to subdivide results into climate change subcategories and extract the carbon footprint ISO 14067 from EF 3.1 results? 

Is the resource use fossils and climate change the basis for this?

Thank you in advance!

Kind regards,

Johannes

Answer 1

Well you need to have an LCIA method that supports this subdivision, but that is it (provided that the database supports this split as well, i.e. has elementary flows for the different subcategories, as EF does).

Answer 2

There is now an "IPCC 2021 (ISO 14067)" method in the openLCA methods package. It's nothing else than IPCC 2021 (incl. biogenic carbon uptake/emissions), but with some different sorting of the results (Aircraft, Biogenic emissions, Biogenic removals, Fossil, Land use, Total emissions). 

You cannot use EF 3.1 for this, because EF 3.1 is based on the IPCC 2021 factors without considering biogenic carbon uptake/emissions (0/0 approach). Furthermore, the EF 3.1 has a tiny difference to IPCC 2021 (sulfur hexafluoride CF is slightly different), since EF 3.1 was based on the preliminary IPCC 2021 report when it was created/developed by JRC and the "default" IPCC 2021 method uses the final report.
