"Tourism carbon footprints were calculated using both residence-based accounting (RBA) to attribute emissions to the countries of visitor origin and destination-based accounting (DBA) for countries where tourism expenditures takes place."
Grey = domestic travel footprint
Green = inbound tourism footprint
Blue = outbound tourism footprint
Notice anything?

@peterdutoit interesting study. A pity that the raw data for that chart is not accessible (that I could see).
e.g. I infer that, at 3.6% of 3.9GT, the UK’s outbound tourism amounts to ~140 MT, but that must be just the blue bit, so the grey domestic bit can only be guessed at. But that assessment doesn’t look quite right relative to the x-axis.
It would be better if the grey bit was integrated with both blue and green in a single chart and that the data is inspectable.
