Some other “carbon factor” datasets that are top of mind:
- OpenImpact. A new-ish (and very exciting!) Building Transparency data product.
- Gabi/Sphera. In addition to their LCI data product (Gabi, which is behind Tally), they also sell generic carbon factors. They now call this “Sphera Managed LCA Content” to be pithy.
- Inventory of Carbon & Energy (ICE) Database. You’ll see this embedded in a lot of free tools.
- Quartz. Mostly deprecated, as far as I know.
- EEIO data. If this is general list of carbon factors, are you interested in spend-based factors? There’s a plethora of government databases here, as well as some proprietary versions (e.g., CEDA from VitalMetrics)
With your list and this list, though, each dataset is assembled in different ways and meant for different pruposes. Gabi, for instance, is generic harmonized data. EC3 collects EPDs product-specific data but product-specific EPDs aren’t all harmonized. 2050 Materials provides generic data, but it’s calculated a measure of center from a collection of EPDs. OneClick provides data from multiples sources together, in addition to other data products–I’d recommend digging into their QA/QC (there are some corner cases). Etc. Etc.
Re: comparability. I 100% agree that this is a major issue, both within and between datasets. And within and between all the datasets mentioned so far, there’s likely some comparability issues worth digging into. Each data product and modeling approach is for a different use case, some of which might be more relevant to what you have in mind.
Happy data’ing!
