It’s good that Oxfam analyses and publicises such data - for too long global comparisons focused on national average per-capita. However, maybe even 1% is too large a group that obscures the diversity within - I guess the 77m people (int that analysis) include many relatively old people who are nominally wealthy by owning a house in an expensive city, but don’t (any longer?) travel much. Heating such houses emits some tons, but not 76tCO2/yr, a figure which must be pushed way up by the fewer jet-set types.
