CO₂OhNo - CO₂ emissions from flying

Origins - I just wanted to estimate the carbon dioxide emissions of an upcoming flight... now I have this whole project

tl;dr - Flight CO₂ emission calculators have huge uncertainties which users are not informed about

Emissions calculations during the Covid-19 pandemic

emission calculator comparison
Radiative forcing - pick a multiplicative factor between 1 and 3
Radiative forcing - bringing together the arguments for the different RF factors
Seating class factors - more legroom means more emissions
Flight distance - traveling on the great circle
Plane speaking - effect of aircraft model on emissions
Viable vias - checking 2 + 2 = 4
Going nowhere fast - emissions of a zero distance flight
Passenger load factor - scaling emissions by occupancy
Stopover vs flyby - the difference between direct and indirect flights

The post-flight carbon offset - replacing averages and uncertainty with data and measurements
Average flight CO₂ emissions - forget trying to work this out accurately, just take the average

TUI Miss-take flight BHX-PMI - passengers were each responsible for 94 kg of CO₂
France suspends short domestic flights - but flight distance alone doesn't determine emissions
AeroSHARK film to reduce emissions by 1.1% - and add uncertainty to passenger CO₂ calculations
