Kevin Anderson 2012:
"The inconvenient truth of carbon offsets"

This almost puts an end to My Great Idea:
for CO2 from your 1 flight per decade, multiply tons by 2 and € 680, and put a PV installation on poor family's roof for that amount.
Almost. Because PV is infectious signalling, the CO2 for electricity really doesn't get emitted and PV helps that family out of poverty.
But it is crucial that you watch that it gets truly done. Plenty poor people in your own city so you can factcheck it. Don't trust any organisation with doing it in India.
It is un-trustworthy organisations which force this idea into purely personal choice, and personal choices are insufficient. :(
P.S. € 680 per ton of CO2, times 2 for 
CO2, are the guesstimates by German EPA Umweltbundesamt for repairing damages occurring up to 2100. https://www.umweltbundesamt.de/publikationen/methodological-convention-31-for-the-assessment-of
I shouldn't be quoting it as I don't know how they assign € to the broader impacts of malnutrition or to deaths in famines, or wether the experience of dying in a mudslide is worth more than in a wildfire – and how they put a € on the friends' experience of such a loss.
But it works for ridiculing a carbon #offset of €35 per flight.
A roundtrip Frankfurt - Auckland is about 40,000 km. A person km in long distance air travel got assigned € 0.1606 in above PDF, table 3031, page 38. ( € 0.237 /pkm for short distance)
So an offset for this flight would be € 6424 – if we were to trust the calculation, and if we were to ignore damages occurring after 2100.
