CH4 Emission factors - there are still old ones included #475

I mentioned before that the tool still includes old emission factors

The once that I highlighted are not in line with the IPCC 2019 update. Is there a reason they are still there?

The EF for Trickling Filter is also not included in any IPCC publication. I think that this is just a custom value developed for Sedacusco.

Hey the EFs in purple are also not listed in IPCC, and the logic is not clear (EF for recovery in anaerobic reactor is relatively high, in lagoon it's zero, but in both cases you will have losses and CH4 dissolved that can't be captured easily and will be emitted in a settling tank etc.)

The EFs for wetlands were derived from some scientific papers, not IPCC if I remember correctly. Now IPCC refers to another IPCC publication. This should be checked.

Ok, I've removed the ones marked in yellow. I will check the wetlands document

I'm checking it here: https://www.ipcc-nggip.iges.or.jp/public/wetlands/index.html
