carbon footprint

Originally proposed at Wikidata:Property proposal/Natural science

   Done: carbon footprint (P5991) (Talk and documentation)

Description	Total emissions caused by an individual, event, organisation, or product, expressed as carbon dioxide equivalent. Has to be calculated via a scientificly proven methodology.
Represents	carbon footprint (Q310667)
Data type	Quantity
Template parameter	This proprety request is part of the project of creating an infobox for materials
Domain	Statistical property of all individual, event, organisation, product...
Allowed values	Any number.
Allowed units	kilogram of carbon dioxide equivalent (Q57084901), gram of carbon dioxide equivalent (Q57084921), tonne of carbon dioxide equivalent (Q57084755), gigatonne of carbon dioxide equivalent (Q57084776) gram of carbon dioxide equivalent per kilometre (Q57084839), kilogram of carbon dioxide equivalent per kilogram (Q57084968)...
Example 1	SAE 316L stainless steel (Q28453931) → 3.9 kilogram of carbon dioxide equivalent per kilogram (Q57084968) [1]
Example 2	6105 aluminium alloy (Q19903155) → 8.3 kilogram of carbon dioxide equivalent per kilogram (Q57084968) [2]
Example 3	AISI 420C / EN X46Cr13 martensitic stainless steel (Q55714959) → 2 kilogram of carbon dioxide equivalent per kilogram (Q57084968) [3]
Source	w:carbon footprint
Planned use	Creating an infobox for materials

Motivation

This has hopefully become an important data for material selection. -- Thibdx (talk) 21:31, 8 October 2018 (UTC)

•  Support David (talk) 06:57, 9 October 2018 (UTC)
•  Support This looks well-thought-out and quite general, thanks. ArthurPSmith (talk) 18:38, 9 October 2018 (UTC)
• Question: Other concepts, like air travel, have a "carbon footprint". Will this be used for those also? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 14:23, 12 October 2018 (UTC)
  • Yes, as long as there is serious sources. It is just a matter of specifying the right unit. -- Thibdx (talk) 17:10, 12 October 2018 (UTC)
• If CO2-equivalent is already specified in the unit, is there any reason for this not to just be "emissions", and used for all emissions? Are there other areas where this may be useful? --Yair rand (talk) 18:07, 17 October 2018 (UTC)

I would find it to be very unprecise. Carbon footprint refer to specific methodologies to assess the whole lifecycle. Emission does not says what part of the lifecycle is considered. The emissions of a car generally refers to it's emissions when it is used. That is very different from the Carbone footprint. --Thibdx (talk) 20:10, 17 October 2018 (UTC)

I see. Perhaps the proposed description should be modified to make the use and methodology clearer on that. --Yair rand (talk) 20:32, 17 October 2018 (UTC)

Modified. --Thibdx (talk) 09:15, 18 October 2018 (UTC)

•  Support, seems like a useful property. --Yair rand (talk) 17:58, 18 October 2018 (UTC)
