"Seems you've also wasted power and contributed CO2 as well?"

CO2 alone assuming there are no hot chilli involved:)

edit: on a more serious note, companies don't waste fuel for no reason, so I'm sure it was a test flight which they decided to fly in a creative way to bring more eyes to the brand. People wandering around every day, every year, in elephant sized pickups doing things a small car would be enough for are a much worse source of pollution.
