I completely changed my attitudes towards flying when I read that even though it produces significantly less CO2 than a Boeing 747, the Airbus A380 still produces a huge amount of CO2 when flying from London to Los Angeles. I was aghast, I can’t remember how much but they were horrifying figures and really put me off taking long haul flights.
So I bought a Cirrus Vision Jet and I’ve never looked back - being much smaller it‘s dramatically reduced my carbon footprint. I mostly only fly as far as I can without refuelling now, so Geneva, St Moritz and Monaco are all in easy reach for the for the weekend - I drive if I’m staying longer - but I only fly to LA, New York, Hong Kong or Tokyo if I really have to now, never just for fun.
Like an EV it requires an upfront investment, depreciation is heavy, and building one has its own environmental impact to consider. It would be irresponsible to buy one and for it to be sat unused for most the week, so I share with three others - my wife and two kids use it too.
