By 2050, airlines are expected to carry about 10 billion passengers on flights
Globally, just 1% of the population generate half of all emissions from the aviation sector.
But can the aviation industry ever be sustainable?

You never get around to mentioning that aviation is responsible for only 2.5% of greenhouse gas emissions.

You do realise that it might only account for a very small amount of emissions, but at the same time only a tiny amount of the world's population travels by air at all. So if more people were to get into the fortunate position of affording a ticket, it's gonna account for a far greater proportion of emissions which is why we'll need to make it sustainable!

Aviation contributes 2% of GHG emissions. If we got rid of that 2% it would be like a fart in the wind. While we should increase efficiency, it would be far more effective to target energy generation and the ground transport industry to reduce emissions which both combined are about 50% of emissions.

True.. The largest contributor to carbon emissions by a long shot is electricity and home heating.. That's not to say we shouldn't discourage or cut down on flying though, especially domestically-in favour of trains and by making train travel cheaper...

@merrymachiavelli2041 Ай бұрын

The problem with this argument is that almost all sectors individually contribute very little to carbon emissions, if you sufficiently split them out. CO2 from the production of plastics is small, from domestic heating is small, from the pork industry is small, from shipping is small, from concrete production is small...etc. So people can _always_ turn around a say 'well x only contributes a tiny amount to carbon emissions' but if we do that for _everything_ then we're screwed. More specifically though, as the video explains, the problem with aviation is that there isn't an obvious fix. We _know_ how to electrify the grid and ground vehicles, and the world is moving that direction, especially how many renewable energy sources are significantly cheaper than fossil fuel alternatives. You say we should target those things - well we _are_ . We need to cut down on flights _as well_ . There isn't an obvious way that the aviation industry in its current form can adapt. Combined with rising demand, we should expect aviation emissions to grow, both proportionately and in absolute terms, in future. Aviation emissions also have a bad habit of escaping national accounting in any one state, and so it's harder to pressure governments to act on them. There's also honestly a fairness problem. Cutting emissions in many areas is legitimately painful - it will likely mean higher energy costs and general inflation, which is going to disproportionately be harm those on low incomes, both globally and within developed countries. Relative to all those painful decisions, cutting down on flights is relatively painless. I don't really care if rich people can't take private jets or middle-class people can't jet off half way around the world to lie on a beach. Cutting down aviation emissions is low-hanging fruit.

The video dismisses electric propulsion without much elaboration. In fact, battery eVTOLs might have some helpful use cases, at least for short distances. And fuel cells are more energy dense than batteries, so electric planes with fuel cells are anear-term available technology that could replace a significant percentage of short haul and regional feeder flights. In principle, some existing planes could be retrofitted with fuel cells, so decarbonization of those planes could go faster than fleet replacement.

"fly less", "spend holidays domestically" ??? That would be the guarantee we don't get our issues fixed at all. We can't save the planet without getting together and doing it together. Only all people of the world aligning in peace behind that overarching, pressing, goal makes it feasible to achieve. Furthermore it will only be to achieve, when the best talents in a free and open discourse develop the best solutions. All that will not work with expanding isolationist, nationalistic, violent, suppressing autocracies. These autocracies though - only find real support among that part of their societies, that does not have passports, that does not travel abroad, that does not have exchange and experiences with other cultures. Only if many more of these people AND Mrs. Hewitt travel more, see more of the world and other places (and get out of their own bubbles there ...), only then we have a chance for understanding between different cultures, for peaceful co-existance, for sufficient openness and freedom, thereby for the fertile ground to get this planet saved. Yes - it might very well be, that we allow aviation a special role and continued pollution but focus, even if less popular, much more on production, construction, heating and commuting.

Airships are the only way round this problem at the moment. Really big ones. It was unfortunate that the Hindenburg disaster put us off this environmentally friendly mode of transport. Heavier than air transport is just a very inefficient way of staying aloft. And it's effect is probably far worse than you think. How can we be sure? The only time air traffic stopped since the 70's was for three days after 9 11. It's hard to get accurate data (a cover up?) but as far as I can fathom the data shows that once the skies cleared an appreciable effect on global warming within a day was detected (within hours) and the reverse once normal traffic returned. It was only US airspace but it had a trully global effect. For 50 years we've been constantly pumping co2 into the atmosphere from 10 kms up causing a thick blanket around the Earth which multiplies the effect several orders of magnitude EVERYWHERE as the greenhouse is substantially bigger due to the slow downward drift of co2 to the oceans where it is mostly absorbed.The few places where aircraft don't fly often are over Antarctica and the Himalayas. But it still spreads. And it's being constantly replenished. Ground based co2 emissions have a far lesser effect on the climate as a whole, as the co2 molecule is relatively heavy and sinks downwards into the oceans. Urban heat islands and surface emissions don't cause a worldwide smothering blanket of co2 10 kms thick. When I drive out of the city into surrounding woodland the change is noticeable. So it was post 9 11. We don't have accurate measurements at altitude but I am convinced that it is worse than the more localised effect of ground based emissions; co2 is a heavy molecule and so it takes a while to deplete downwards but it happened once. Only once. Ocean temperatures are rising too partly because of this but also the influence of industry on rivers and coastal areas, like a radiator. Arctic ice is largely gone from the north coast of Russia precisely because most Russian rivers run north dumping all that heat from the heavy inefficient industries warming the water of the Ob, Lena and Yenisei rivers. That doesn't happen in Canada, Alaska and Greenland, but i believe that 50 years of uninterrupted air traffic has contributed far more to global warming.

It is unlikely that mass transport via passenger jets will ever be sustainable. At the commuter end of aviation, electrically powered short range small aircraft are already flying. A massive increase in the energy density of batteries is required for much larger electric aircraft to built. That technology development may take many years, maybe decades which is outside the window of opportunity to limit the rise in temperature of the earth’s atmosphere. There is an assumption in this video that combustion based engines used for aviation can be used sustainably. Currently, combustion based aviation engines consume oxygen, fuel and produce a range of pollutants, with Co2 being one of them. Let’s see a more comprehensive explanation of the end to end fuel cycle of proposed “sustainable fuels”. How are all the pollutants managed including Co2?

2/3 of travel is for leisure Over half the population of rich countries never fly. About ninety percent of the world population never fly. Rich countries will be least affected by global warming and have by far the largest per capita carbon foot print Tropical countries which will be most affected by global warming. Yet the vast majority of the population of these countries never fly and have small per capita carbon foot prints. There is no sustainable aviation. Aviation came about with fossil fuels and will disappear with fossil fuels. If we ever do produce clean hydrogen in large quantities, that hydrogen should be used to de carbonize steel production which uses coal for iron ore reduction. Steel production accounts for 8% of global emissions. Steel is a vital need, leisure travel which concerns a small minority of the world population is not. As for carbon capture, de carbonizing cement production will require massive carbon capture, as all known methods can only reduce half of cement production CO2 emissions which currently account for 7% of world CO2 emissions. Again, modern civilization can not function without cement production.

Yes. Just stop using it or stop fighting each other and competing against each other. Start building together as a whole. Solar planet wide trains and more would come so easily? You could eventually do it with much sacrifice but as you are all too cursed with greed it will sadly never gonna happen. Humanity is not going to make it in this universe going this way, calling it now.
