Fom the article:

A single flight in a private jet can easily emit as much carbon dioxide as the average annual carbon footprint for an EU citizen – 8.2 tonnes

Oxfam:

The richest 10 percent accounted for over half (52 percent) of the emissions added to the atmosphere between 1990 and 2015. The richest one percent were responsible for 15 percent of emissions during this time – more than all the citizens of the EU and more than twice that of the poorest half of humanity (7 percent).

I think what you built is legitimately cool but your efforts are erased many times over by a single flight these people take. I think thats enough to suggest you shouldnt empathise with the rich being given an inconvenient message, not that it was meant to change their minds, its to raise awareness in us, the general populace.

Also, we need systemic change, not just individual effort. We will have energy needs irrespective of how efficient we make things, and political pressure is how we will force away from fossil fuels.
