Flying is a bit unique in that there aren't really viable alternatives. It also accounts for a fairly small portion of emissions. Land transport (cars and trucks), power generation, and heating are where the big wins exist with viable alternatives.

Here is a good list of 'fuel per seat (in mpg)' numbers for various airplane configurations and flight durations: https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft#Examp...

The total average across the industry in 2018 was between 67 and 81 mpg. Modern planes are in the 100-120mpg range.

I think the way airline tickets are priced is a big factor, and needs to change.

It is often cheaper to take a connecting flight to an airport and flying from there than to start from that airport. That disincentivises taking a low-carbon-emission train to the airport and experiencing more of (and spending more in) the city near the airport than just its airport.

Often, for longer flights, the more stops, the cheaper the total ticket gets. Planes consume more fuel at take-off and landing, making the the carbon footprint increase with these cheaper tickets. And the more you fly, the more points you get that could pay for more flights.

It should be the other way around: air-travel carbon tax should be progressive. You should pay more each time if you fly more often. That would reduce the number of flights in total while still allowing everyone to take that "trip of a life-time".

It’s 2.5-3% of all global emissions.

People who complain about aviation do more harm than good.

We would accomplish more by closing a few coal power plants and replacing them with renewables or nuclear. And no one would even notice.

Can you believe it’s almost 2030 and we still haven’t reached peak coal.

We're screwed and powerless so activate ostrich mode is one way to deal with things, at least on a personal level. Probably better for your health

Even hot air balloons burn fuel....How do you propose we cross great distances: horse, sailboat, or walk?

I guess if you are really serious about saving the planet from airplanes, you could start a network of similar-feeling folks and begin randomly bombing enough flights to terrify the world into not flying.

Give yourself an edgy name, like the Children of Kali, to make it stick.

Honestly, if you think the stakes are that high then you implicate yourself with anything but fully committed action. Anything less, and you just seem preachy and screechy.

PS: It's a book called The Ministry of the Future. Try reading once in a while. Whoosh.
