About these figures. The CO2 per passenger is for the whole city pair, so it covers every airport the route uses. The airline filings the figures come from don't split fuel by airport, so we can't say how a flight from ONT compares with one from a neighbouring airport. The share column is the part of the route's passengers that flew through ONT, from the same filings. How the figures are built.
