Is it OK to fly if rail is too expensive?

I am glad that you are trying to follow your convictions. However, there are a few things to consider.

Typically, if you are making personal travel decisions, it is responsible to think about your impact. But if you are taking a business trip, go for what is most efficient and economical.

Also, airplanes are quite efficient; are you sure that the train is using clean burning fuels? Finally, think about the trickle down impact of all the extra money you are spending on the train. You are putting money in other peoples hands, and do you really expect them to spend it responsibly?

 

[ExactlySolved]

Sorry I forgot to mention that my motivation for not flying is climate change.

Ahahahahahahahaha!

But seriously, if and when carbon becomes an environmental problem, the free market economy will adjust prices to disfavor it. As long as flying is less expensive, there are no real forces to disfavor flying, only imagined ones.

The fact that you 'believe' that "ordinary" trains are "far cleaner" shows you haven't even done your homework before making such an irrational decision on your lifestyle.

Nothing is certain, particulaly in this case, evidence is a reason for belief. The evidence that I have read from various perspectives leads me to believe that flying is probably the worst form of transport over short haul(ish) distances.

Either way, I fly for fun when I have the chance, I highly recommend it. The train is slow, makes frequent stops and is a time sink (you said no high speed trains).

I'm a hypocrite, I can;t tell anyone else not to fly as I've done a fair bit myself. For me I can;t reconcile my concern over Global warming with flying to spain. Perhaps I've got it all wrong, maybe CERN will kill us all with a black hole. The pressence of uncertainty isn't reason to dissmiss the wider picture that, from what I've read, flying at current levels is just unsustainable.

I really don't care enough to change a mere 4.9% of pollution. That's a very bad way to try and save the planet. You're probably better of trying to reduce the other 95% of the problem.

I do care. Besides this argument is often put forward by the aviation industry, and it's aprrox. true. Just to illustate:

Now, of course I can cut back on domestic energy use, I can recycle etc etc to reduce the other emmission sources, and I try to but this would be marginal compared to the reduction from not flying as an individual

Neu, the plane will be making the trip whether you are on it or not. It's commendable that you want to save energy/reduce pollution, etc, but the fractional extra fuel that plane will burn because you are on the plane won't have much impact in the big picture.

Supply will have to learn to meet demand, as Office shredder says:

Besides, how is his refusal to fly not the free market beginning to adjust?

Finally, think about the trickle down impact of all the extra money you are spending on the train. You are putting money in other peoples hands, and do you really expect them to spend it responsibly?

This is quite a strange argument for flying. I'll still be putting money into other people's hands by flying no? and what's so bad about that?

Most likely because larger airplanes are more efficient per person per km but aren't used over short distances. However, from what I remember, Boeing was moving towards changing this.

You're right to question it, I just used it as a crude example of what other emissions are, it's the first one I found. (I'm at work, shouldn't really be on here!)

By the way I found a connecting train that was cheaper, altogether it's £150 return and I get to stop off in Paris for a few hours.

[JaredJames]

Neu, firstly I am not a fan of reports given by media as there is generally a lot of hype that goes with them.

Your pie graph actually shoots your argument down. The percentage of pollution from aviation is extremely low in comparison to the others. Given the number of flights there actually are (on average 1000 per day to heathrow alone), to reduce that figure by even 0.1% would require a massive drop / reduction in airtravel. So it is far easier to reduce the red sector for instance by making businesses, agriculture etc. more environmentally friendly, or the dark yellow one by improving domestic energy consumption.

http://www.foe.co.uk/resource/press_releases/heathrow_terminal_5_why_it_26032008.html and this is from Friends of the Earth, the subject of said report I disagree with, but it gives the figures for flights into and out of heathrow.

Also, people keep on about carbon emissions when methane is 20x more polluting in terms of global warming. (I'll try and dig the link out for this one.)

 

[ExactlySolved]

I'm not the main person in this thread who has made that error, look at all the posts on page 2 e.g. "one person won't make a difference" etc, the freshman economics concept you mention would be a more relevant study for them.

One of the assumptions of the theoretical free market model is that we have rational actors with perfect information; in this case we have almost the exact opposite: misinformation and hysteria. But as you say, this is not a debate about global warming, it already assumes this as a foregone conclusions. For some reason this forum strongly supports non-mainstream physics, but supresses any non-mainstream climate science.

Given the number of flights there actually are (on average 1000 per day to heathrow alone), to reduce that figure by even 0.1% would require a massive drop / reduction in airtravel.

It's better to think of my individual carbon footprint. If I fly it would be the single biggest factor in my footprint.

And to take your example: if there are 1000 flights through heathrow, a 0.1% drop would be 1 flight. Hardly a massive reduction.

So it is far easier to reduce the red sector for instance by making businesses, agriculture etc. more environmentally friendly, or the dark yellow one by improving domestic energy consumption.

I can only affect my actions. The graph (whether valid or not) represents total UK emissions. I can only directly affect emissions from my actions and consumption e.g. eating/not eating meat, driving/cycling etc etc. Of course I contribute to all the factors on the graph but I'm guessing I'm not the prototypical consumer and cause exactly the same fractional emmissions as the UK.

As an individual the decision to/not to fly makes a massive difference to my CO2e emmissions.

Also, people keep on about carbon emissions when methane is 20x more polluting in terms of global warming. (I'll try and dig the link out for this one.)

So what is your point? It is true that methane has a far greater warming effect, but it is a smaller contributor to global warming than CO2 which is far more abundant, it is also true that water vapour has an even greater warming effect.

What idiot thought that up?

 

[JaredJames]

The fact is, global warming is here. But, the debate is whether we are the sole cause or simply adding to the problem (and if so to what degree). In other words is it a natural or man made phenomenon? We already know the Earth goes through a cycle of heating up and cooling down (ice ages rign any bells?).

In terms of airtravel, it would take a lot of people to boycot it to make a difference. So in that respect, one person won't make a difference. When you consider the speed at which an aircraft gets you somewhere in comparison to a train/boat or other form of transport, by boycotting them you would slow down the modern world. A business trip to, say, Sweden by train would require an overnight stay whereas with flight you can be there and back within a working day.

People don't want to lose airtravel because it is a useful and certainly in a time respect, efficient way to travel. (I would love to see a train or boat get to Australia in 24 hours. That is if a train could even manage the little problem of an ocean in the way).

 

[mgb_phys]

If you have a decent rail system the plane is not that time efficent.
London-Paris is 2:30 hours by train, by plane it's an hour to get to Heathrow, a 2hour check-in, a 1 hour flight (assuming the plane isn't a couple of hours late) and 30mins from CdG into Paris.
In France and Germany there is almost nowhere that a regional jet is faster than the train from city centre to city centre.

And to take your example: if there are 1000 flights through heathrow, a 0.1% drop would be 1 flight. Hardly a massive reduction.

No, that is simply 0.1% drop in flights not carbon emissions. Because 7% is the UK overall from aviation. That means you take every flight into the UK. But for simplicity, let's say we only have heathrow. There are 480,000 flights into heathrow each year representing 7% of carbon emissions, which means each individual flight (ignoring aircraft type and load) represents ~1.46x10^-5% (0.0000146%) of overall emissions. This means for a 0.1% reduction you would require a reduction of 6900 flights per year or 19 per day. Now, again not a particularly high number, but when you extrapolate that to each airport in the UK alone (a rough count gives me about 30 international/major alone) that proves you need to reduce somewhere in the region of 570 flights per day (207000 per year). Even if you allow heathrow as the largest and busiest, it still leaves somewhere in the region of at least 100000 - 150000 flights per year. All for a 0.1% reduction in carbon emissions. That's a lot of people boycotting flying.

The statement "to reduce that figure by even 0.1% would require a massive drop / reduction in airtravel." referred to the previous sentence of "The percentage of pollution from aviation is extremely low in comparison to the others.", not the "1000 flights per day" bit. Please take things in context.

To me it is obvious that this thread was started because worrying bout the environment is the socially 'cool' thing to do, not because anyone should really be concerned about this decision.

If you think that the government and media forces will some how avoid the free market tragedy of the commons, that if everyone acted in the interest of the whole then carbon emissions would be substantially reduced, then you have failed to understand the magnitude of the economic forces that will prevent this from happening. Even the world leaders who signed the Kyoto Protocol know that it is entirely symbolic e.g. no one expects a 5% reduction in emissions to effect global temperatures. The agument that 'every little bit helps' is plain wrong when it is obvious that we could not cut out a significant amount of carbon consumption withot fundamental changes to our civilization. "Cutting back" on your "carbon footprint' cannot possibly effect global temperatures, unless everyone grew their own food and gave up all manufactured goods, and forgot about traveling in motorized vehicles entirely. I laughed at this thread because its amusing to me that some peole would feel guilty and make hair-split decisions over something they cannot possibly effect.

You've misunderstood the point. If loggers and fishers were rational and had perfect information, then overlogging and overfishing would not occur. Therefore, since these things do occur, it follows that the actors are irrational or posess only imperfect information. The point is that, the irrational actors (climate change hysteria) and imperfect information (vaguery, uncertainty, and group think in climate science, and the massive misinformation campaigns in the media), do not form a coherent force in the free market.

No. Free markets can still have externalities. There are plenty of examples of markets with imperfect competition, but those are not examples of that -- they're example of tradgedies of the commons, which are perfectly compatible with the free market.

[Moonbear]

This is probably one of those cases where the correct answer is, "It depends," in terms of which is better for the environment. If a particular route, on either train or plane, is popular enough to fill the train or plane, then the fares get lower because the operating costs are spread out over more people while a profit can still be made. If the train fare is much higher than airfare, it might indicate that the train is not running full. So, even if on average a plane is worse than a train for greenhouse emissions or energy usage, any particular route may not fit that category. If I'm on a train with only a handful of people, surely that can't be better for the environment than a plane that is packed to capacity. Similarly, running an entire train for one passenger is unlikely to be better than that person hopping into their personal car. On the other hand, running a full train is going to be better than every one of those passengers each driving their own car. I'd take a very low airfare as an indication that it's a popular route and full flights.

I didn't even think rail was better than flying for the environment. I choose which one to use based on convenience, routes, schedules, distance traveled, cost, etc.

 

[ExactlySolved]

Why all the vitriol? You're extrapolating a lot from my post. Even if my motivation for reducing the impact of my journey was to look cool, would it matter?

The thing that bothers me is group-think, or 'hysteria of the crowds', and any situation in which people stop applying logic and start to do things because everyone else is doing them is inherently bothersome to me; it just bothers me to see people failing to apply logic in situations where it is appropriate for logic to be applied. The source of my bother is that I like progress, from the point of view of civilization as a whole.

Do you have evidence that people with better information will act to avoid a tragedy of the commons on their own?

That the tragedy of the commons results from a lack of perfect information is a purely logical consequence of the definitions involved. Therefore the proposition is known a priori, and so it would be redundant to list examples which are known a posteriori, especially when such examples (with perfect information) are unlikely to have ever existed. The point I was making does not depend at all on there having ever been a real situation where actors had perfect information.

I take this to mean you're not an advocate of anthropogenic climate change; this is where we differ. I would be interested to hear why you think this. I'm not trying to antagonise/patronise I'm genuinely curious to hear your opinion.

Regardless of my dis-advocacy, the arguments I gave depend neither on global warming being actual nor on humans being the cause; I argue that even if global warming is occurring and even if humans are the cause, that even if everyone choose to never fly a plane again this would have a negligible impact on CO_2 emissions, and so any moral agonizing on environmental grounds over the question which is the title of this post is thereby illogical, and thus bothersome to me.

Although this has drifted from the OP a lot and will probably be locked before your response.

Therefore I am not going to argue about climate science in this thread, since in GD discussions about drinking alcohol, kitty cats, small talk, and formulaic jokes/puns are always on topic, whereas unpleasant arguments are always off-topic.

[JaredJames]

Have you evidence that this is the case? This is v.relavent to OP. Bear in mind I was referring to short haul.

Based on your own pie graph earlier, if every aircraft stop flying in the UK for one year (long and short haul), we would only reduce emissions by 7%. Whereas if you installed more wind turbines, wave platforms and solar systems, you could run huge sectors of domestic and industry from them, reducing the need for coal/gas/oil/nuclear. This would create the possibility of reducing the large red/dark yellow segments far more than 7% thus creating a larger impact on emissions and the greenhouse effect. This is why, you saying you won't fly because of your own carbon footprint I find laughable.

I argue that even if global warming is occurring and even if humans are the cause, that even if everyone choose to never fly a plane again this would have a negligible impact on CO_2 emissions, and so any moral agonizing on environmental grounds over the question which is the title of this post is thereby illogical, and thus bothersome to me.

Well I agree with ExactlySolved on this one, here's a rough calculation based on your own number for emissions and friends of the Earth's heathrow numbers (using these sources, as in people who support your view and yourself to avoid bias on my part):

I'd like to correct the calculation I did earlier, I have corrected it in the previous post, but here it is again for people who haven't seen it:

It's better to think of my individual carbon footprint. If I fly it would be the single biggest factor in my footprint.

And to take your example: if there are 1000 flights through heathrow, a 0.1% drop would be 1 flight. Hardly a massive reduction.

No, that is simply 0.1% drop in flights not carbon emissions. Because 7% is the UK overall from aviation. That means you take every flight into the UK. But for simplicity, let's say we only have heathrow. There are 480,000 flights into heathrow each year representing 7% of carbon emissions, which means each individual flight (ignoring aircraft type and load) represents ~1.46x10^-5% (0.0000146%) of overall emissions. This means for a 0.1% reduction you would require a reduction of 6900 flights per year or 19 per day. Now, again not a particularly high number, but when you extrapolate that to each airport in the UK alone (a rough count gives me about 30 international/major alone) that proves you need to reduce somewhere in the region of 570 flights per day (207000 per year). Even if you allow heathrow as the largest and busiest, it still leaves somewhere in the region of at least 150000 flights per year. All for a 0.1% reduction in carbon emissions. That's a lot of people boycotting flying. All for a lot of nothing.

Your carbon footprint is tiny, like I said before, it would take everyone to boycott flying to have a noticeable effect. Whereas using the suggestions above could prove much more effective.

Just a quick one, if you again only use heathrow (ignore all other airports/flights), taking the figure of 1.46x10^-5% for each flights carbon emissions, assuming an average passenger complimnet of 100 (again ignoring cargo), this would make an individuals carbon footprint somewhere in the region of 1.46x10^-7% (0.000000146%) of overall emissions. Bring cargo and the fact most aircraft have a passenger compliment of around 250 and one persons really does become negligable. Once again, a massive boycott would be required. Of course that figure is for heathrow alone, if you bring in all other airports and extrapolate for the whole of the UK, you could take that figure up a few orders to say x10^-8 or even x10^-9. Thats how small each persons impact is. You are better off going for your own domestic improvement, and rallying for more sustainable energy sources.

Me, personally, I believe we need nuclear to continue but I am simply providing another point of view here and so let's not start a debate on nuclear.

It has really annoyed that people will sit and argue politics and definitions of things, yet when faced with hard figures in front of them they cannot respond to them and simply choose to ignore them as with my last post with the original calculation. The numbers give the facts and if someone was to provide me with the equivelant figures for trains (total number running in UK long and short distance etc) I would perform the same operation on them and get us a definitive answer.

 

[JaredJames]

Another thing, if you work out the carbon emissions from electricity use per person, the figure would be much lower than that of per person for aviation. Meaning you would require many more people to have an equivelant impact on emissions. So on the face of it, aviation is worse.

However, you must remember that for a decrese in aviation emissions you would have to have a huge number of people to stop flying/using airmail etc. Whereas to reduce electricity emissions, you wouldn't require anybody to do anything. A power company could simply construct a number of sustainable sources and there is your reduction. The individual would have to make no changes.

Think about it, there are easy ways to reduce emissions and hard ways. Boycotting aviation on your own isn't an easy option.

 

[ExactlySolved]

I don't personally know anyone who has made the same decision not to fly,

Whether or not you are trendsetter amongst your peers, it's hard to deny that the media and the polticians have been aggressively pushing this 'carbon footprint ' nonsense, and I myself have seen articles on this subject that specifically relate the 'evils' of flying in commercial jets. If you have not seen any of these materials and came to your decision all by yourself, then I apologize, and my vitriol should be seen as directed towards the (tens of millions) of people who read these articles and accept them blindly.

I've made the decision based on sound evidence that flying short haul is unsustainable at the current rate.

Yes, flying in jets is unsustainable because we are running out of petroleum. Climate change has nothing to do with sustainibility.

Yes trains can be as bad at medium-haul and at low capacity, but like for like over similar timescales there's no competition. Easy decision, easily made now I found cheaper tickets, and I get a day in Paris on each leg of the journey.

That's great; I really am glad that you made the decision which gave you the most personal satisfaction instead of letting the 'climate changers' tell you what to do.

If I don;t need to fly short haul, then surely it would be logical not to. ...What's illogical about that? The premise is obviously where we differ.

It was the original question 'is it OK', which is a request for moral approval. Asking for a comparison between which produces more carbon, or which is better for the environment, would be a logical question, but asking if either one is 'OK' implies that there are moral connotations attached to the decision of whether to fly or take a train, and it is these moral connotations that I am arguing against.

I don't get you're gripe about logic and you're imagining about group hysteria, you think I'm trying to be cool and take the moral highground when you're doing the same thing.

This statement of yours basically reads as "I know you are, but what am I?" The fact is that the media and the politicians in the US, the UN, and the EU are advocating this 'carbon footprint' nonsense. This is the group-think I was referring to. As for me trying to be 'cool', I doubt my argumenative manner is making me many friends, which is of little consequence since my main goal is to fight back against the misused moral pressure that the 'climate changers' apply.

I would argue that your dis-advocacy is a determining factor in this discussion

It's not, and I have made that clear by saying my arguments hold even if I grant for the sake of argument that the climate is changing for the worse and even if I grant for the sake of argument that humans are causing the climate change with our greenhouse gas output. Please understand this, since this is the third post where I have repeated it: I am about to present an argument that agrees with your premises (cc is bad and is caused by humans) but disagrees with your conclusion (individuals should be concerned with their 'carbon footprint ').

The argument is based on this: the Kyoto protocol will have a worldwide cost of over $1Trillion, and even the UN admits that it cannot possibly lower global mean temperature by even 0.1 degree Celsius by the year 2050. In fact, the UN's estimate is 0.07 degrees, and critics of their scientific methodology contend that the change will likely be about 0.01 degrees.

Therefore, even if climate change is caused by humans, no one will contribute to stopping it by 'reducing their carbon footprint .' Even the governments of the world working together and spending such a staggering amount of money will have essentially no effect.

The typical response to this argument is "Yeah, but we have to do something, so let's make a lot of noise and spread misinformation with no real plan to accomplish our goal", which is obviously illogical.

Have you evidence that this is the case? This is v.relavent to OP. Bear in mind I was referring to short haul.
