Improve the flight model by adding load factors by region

[martincollignon]

https://github.com/Tritlo/FlightCarbonOffset this is super cool. Could be nice to integrate flight number as an optional input to activities @Tritlo do you think you could help?

https://theicct.org/sites/default/files/publications/ICCT_CO2-commercl-aviation-2018_20190918.pdf I've reached out to the author as they seem to have all the data needed to make a very comprehensive model.

[martincollignon]

Let's start by adding the load factors by routes (page 12 and 13) from https://theicct.org/sites/default/files/publications/ICCT_CO2-commercl-aviation-2018_20190918.pdf in the current model.

To do's:

• [ ] Add ICAO region on airports.json . Matching by country is shown page 12 in this document
• [ ] Add a file loadfactors.json
• [ ] Make the load factor a variable instead of a constant in [index.js] (https://github.com/tmrowco/tmrowapp-contrib/blob/master/co2eq/flights/index.js#L8) if input is two airport codes
• [ ] Make the passenger to freight ratio a variable instead of a constant in index.js if input is two airport codes

Really interesting problem. There is information on the GHG intensity grouped by passenger class and the type of flight (long-haul/short-haul) for flights to an from the UK. Don't know if this may also be reflective of the general situation. I have been using these statistics for developing a tool recently

@martincollignon great dataset to cover most of the worlds commercial flights!!! :) Do you plan to connect this with highly detailled flight data from services like https://www.flightradar24.com/ (there are other data providers, too, afaik) for individual flights? Thinking in another direction, I can imagine this could become something real-time like "the electricityMap for flying" by showing the approximated CO2_eq emissions of each flight as a trail behind the airplanes ;)

Hi @alixunderplatz, with this and #271 I believe we'd have one of the most accurate models available out there. I can also see some other possible improvements based on this: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/829336/2019_Green-house-gas-reporting-methodology.pdf (page 73-79)

APIs, widgets, etc, are possible ;-)

@martincollignon oops, I meant to post my comment in #271 I'll paste it there

@martincollignon Can I start working on it? Seems like it would be a good first contribution :)

[martincollignon]

Sounds good!

I'm on it :)

• [x] ICAO regions on airports.json. See here. Used this dataset to link airports (referenced by iata) to their country and then to their respective ICAO regions.
• [x] loadfactors.json file. See here
• [x] loadfactor as variable. See here
• [x] passenger freight ratio. Cf above

[pierresegonne]

@martincollignon I think I'm done :) Is there any guidelines for PR/linting etc? If no then I'll create the PR

[martincollignon]

Feel free to create the PR :-)

[martincollignon]

If you're excited about this @pierresegonne there is #271 and #273. Once this is done I'm convinced this will be the best open source flight carbon model worldwide.

[pierresegonne]

Yep these two point seem super important to generate a precise model! Will look into it as soon as this is done :)

[pierresegonne]

shouldn't we close the issue @martincollignon ?

[martincollignon]

indeed!
