Additional production column for S3 data #154

Open MichaelTiemannOSC opened 1 year ago

MichaelTiemannOSC commented 1 year ago

Presently the ITR data template uses a single production metric to cover all S1, S2, and S3 emissions. This creates a problem when the principle downstream "product" is very different than the product that nominally creates S1+S2 emissions.

In automobiles, the production of vehicles (measured as vehicles produced) produce S1+S2 emissions, whereas the driving of the vehicles (measured as passenger miles/kms) produce the S3 emissions.

In oil and gas, the production of a barrel of oil (boe) produces S1+S2 emissions, but the burning of that oil for some other purpose produce the S3 emissions.

Integrated energy utilities (that supply both electricity and gas) could be much more naturally represented by having a production metric in MWh (or PJ) and an S3 production metric in MBtu/therms/etc representing gas deliveries.

In concrete, S3 emissions are defined by convention as the S2 emissions related to the buildings built with that concrete.

I propose that we add a column to the data template "S3_production_metric" or "downstream_metric" or some such that allows us to describe S3 metrics in a natural way, and not as something that is itself unnatural or that forces us to label the S1+S2 production metric unnaturally.

Comments?

Totally agree, I would go with the S3_production_metric version. Thanks for bringing this up.

MichaelTiemannOSC commented 1 year ago

Would you prefer the name "S3_production_metric" or "production_metric_S3"?

ImkeHorten commented 1 year ago

Looking at our other columns, I would probably say production_metric_s3 - should we then also call the former production_metric now production_metric_s1s2?
