Flying consumes a lot of energy, and flying by carbon combustion emits CO2 high up in atmosphere. As good as incremetal improvements like this neither really get fixed by technology like this.
Very roughly a plane emits CO2 equivalent of using 1MW of electricity per passenger in economy. So an intercontinental return flight can be equivalent to a whole's years worth of electricity usage....
- louwrentius 3y agoYou seem to get downvoted but I’m totally unimpressed by this news for the same reason. If we want a sustainable future, the first step is banning private jets, and the second one is to restrict and reduce all air travel. That would have a huge impact on people but I think it’s the moral thing to do.
- bouchard 3y agoI get the sentiment, and there's definitely a lot of work to be done and actions to be taken by the right stakeholders. But just to put things in perspective; all of aviation contributes up to only 2.5% of all global emissions (both direct and indirect).
- louwrentius 3y agoI know, yet I think the conclusion to draw here is that those other polluters are really terrible, not that the aviation is something to ignore because it’s a relatively small part of the pie.
- zzbn00 3y agoThe simplest thing to do is to rapidly increase the price of carbon-emitting fuels by coordinated global taxation of it.
- fulafel 3y agoIndeed. We need to drastically reduce air travel, as there is no technical fix in sight in the required timeframe.
