premise_gwp

Import the official IPCC's GWP100a characterization factors into Brightway2, with the addition of biogenic CO₂ uptake and release flows. This is needed when using premise -generated LCI databases that rely on Bioenergy with carbon capture and storage (BECCS), and any other forms of storage using biomass. Without it, BECCS operations do not yield a net negative carbon footprint.

In particular, it adds:

• "Carbon dioxide, in air", with a CF of -1
• "Carbon dioxide, non-fossil", with a CF of +1
• "Carbon dioxide, non-fossil, resource correction", with a CF of +1

The biogenic carbon balance in the rest of the ecoinvent database should be correct. Hence, using this method, instead of the regular IPCC 2013 GWP100a method, should not yield any difference, as long as BECCS are not present and solicited in the database.
