No need. Given the opportunity to compare, customers tend to be preety good at identifying what they want. But this doesn't mean that any of the offerings they might have will be any better than the service they have now, or that the aggregate environmental impact will be less, or that the costs will
If what they have now is on offer as one of the available services, those wishing to stay with it can do so. But splitting delivery of the same service (shifting a mass of waste) is achieved with more competing vehicles, where is the environmental gain ?
The service isn't the same for each.
In total, the same amount of material is shifted. More people, equipment and road miles may be involved.
Who said anything about the total number of vehicles necessarily increasing? Who said that they would be the same size?
Who said their collective environmental impact would be less ? I didn't hear that undertaking. If I did, I might be little more enthusiastic.
In the meantime, other suppliers will be offering different services at different prices. Some will be lower and some higher. And all increase the aggregate environmental footprint of the exercise.
That is a nebulous term.
Not to people who know what it means.
Contractors compete for the customers' business. They can offer a low priced service Maybe. Certainly. Some customers like to buy on price. Yes - though is there any guarantee they'll be offered lower prices ? The market will decide that. So that's a no then.
Given that the LAs would not be in the food chain, one substantial cost element is removed.
Except to license and police.
As far as pricing is concerned, the market will decide. One element of the market is price competition.
Well - the average consumer may feel they've been had if it does work out more expensive.
Since you already identified that current costs of waste collection are not given to the public, there is no direct comparison to make.
I've identified that you don't know them. I haven't asked.
I happen to think that service is extremely important and value it above price. Others may take the opposite view or rate them more equally. All can be accomodated. No. All can't. Only the price / service spectrum that you choose to identify. But you've already blown it on environmental impact.
I haven't "blown" anything. "Environmental impact" is a nebulous term that is open to individual interpretation.
No - it's pretty well defined. Oddly enough, people who write things like environmental impact assessments, or assess EMS processes know what one is. You don't have to know something personally for it to be known to mankind !
You can't accommodate me, and quite possible many others by taking an existing solution that is adequate, and replacing it with a range of choices that are worse.
You would be at liberty to choose a supplier who operates in the same way as your existing one.
Which guarantees nothing about the change to multiple providers as a whole.
The existing solution is only acceptable to the extent that individuals are not required to take any actions beyond putting all of their rubbish in one set of bags weekly.
This is certainly your view but there's no need to state it as though you speak for all people.
Supermarkets manage it very well by having typically 4 brand threads: - Cheap own brand - Mainstream own brand - Vendor brand - Premium brand People buy what they like and/or what they can afford. Well yes, but there is a difference in that dust carts take up more than shelf space ! To me this all sounds like more carts out collecting on the roads, and more aggregate environmental impact. How will people buy into lower footprint solutions ? People will buy into what they want to buy. If it's on offer. If there is a market, it will be on offer. Apparently the 'as low as it is now' environmental impact for the delivery of the entire service is not on offer - from you.
I'm not offering anything. I already told you that I have no interest in collecting rubbish.
So when people have referred to whingers in this news group, they may have had a point.
I also told you that the term "environmental impact" is whatever the individual decides it is.
You may have told me that, but an MSc course in environmental decision making tells me otherwise.
Which do you think I'm going to believe ?
For example, I happen to think that solar panels on roofs and electricity generating windmills in the countryside have a huge environmental impact visually. Others may actually like them.
The meaning of environmental impact is well understood. The extent to which items with aesthetic consequences in the landscape have environmental impacts is indeed more debatable.
Other impacts, such as those arising from the handling of waste, are mostly easier to quantify however.
If you would like to buy a low footprint solution, you would be at liberty to do so. But if in aggregate, all of the solutions have a bigger environmental footprint than the present single provider solution, I won't be able to go back to the old solution will I ? That depends on what you mean by "environmental foot print" Look it up.
No need. The definition is individual.
No it isn't. It's been understood for a long time, and has been refined somewhat over time, but broadly goes like this.
Environmental Footprint is an indicator of consumption. It is calculated in terms of the amount of area required to deliver the things we consume, in such a way that there is no net use of non-renewable resources.
If anything, Environmental Footprint estimates tend be conservative indicators of resource use because it is virtually impossible to build a complete list of all the things we use.
In the context of Environmental Footprint calculations, 'area' means biologically viable land or sea required to grow the required resources we live on, and to incorporate the waste produced as a consequence of their consumption back into that biological system.
The area units used are hectares with world average productivity. This area may be analysed in terms of requirements for cropland, grazing land, forest to grow raw materials, sea for fish and seafood production, land for housing, work and infrastructure, and land to fix carbon dioxide emissions arising from energy use.
Because the area of available land and sea habitats are known, this indicator enables comparison between the footprint areas required by individuals, populations, or processes, and that available locally or globally.
I'm sure you'll find better, more refined, definitions than that, but the upshot is that these things can be quantified, tend to be under estimates, and despite this, we still need a multiple of the area we have at out disposal.
While slightly different definitions used by different researchers may give rise to slightly different methodologies, as long as the same methodology is used when making comparisons, a fairly accurate relative measure can be obtained for individuals, populations, processes etc, and all methodologies give broadly similar results.
To say "The definition is individual" shows a pretty complete lack of understanding of the field.
In essence you seem to want me to bet the future, at least of waste collection, on your own political ideology, and I decline to do so, because you have no detailed plan, can't guarantee that there will be any reduction in aggregate environmental impact, and can't promise that any aspect of the service that I value will be improved. That isn't what I have said at all. I haven't talked about betting anything or about political ideology. I haven't offered detailed plans or set out to do so regardless of how many times you have suggested that I do so. All that I have said is that there should be a choice of supplier and of service offering for waste collection and that I do not think that a one size fits all monopoly is the right model. It is very telling that you seem to believe that a monopolistic model delivered through the local authority with increasing onus on the customer to do particular things in a particular way with legal compulsion if the customer dares to disagree is the way forward. I think that not only is that a very dangerous state of affairs, but it illustrates a considerable insecurity about the true benefits of the various schemes being forced upon customers. It illustrates a significant concern that we do a lot of environmental damage that we can't individually see or measure.
That may be the case or it may not.
So are you really suggesting that it might be the case that there is no environmental damage that is not trivial to see or measure ?
If one takes that position, taken to its logical inclusion, one would do nothing that might have some impact or another.
No - all work to reduce environmental impact is done in the context of supporting life on the planet, ours included.
Protecting the environment is not about doing nothing, anymore than industry should be about rendering life on the planet impossible.
The point about sustainability is that it's about doing things in such a way that you can go on doing them, not that you do nothing, or bring about environmental catastrophe.
If you want to do a set of things that convince you that you are doing something good about that, then that's your choice, provided that you don't inflict them on others.
I don't inflict anything. I'm too busy delivering peoples various jobs and requests.
I prefer to see demonstrable evidence that something is being damaged and secondly that the proposed solutions, if any, do address it and not make something else, including the economic situation, worse.
Perfectly reasonable, but you are only like to get that if you study the subject. I won't be inflicting it on you. Are you willing to make any commitment to understanding the subject ?
As a result, if we want to start living in a [more] sustainable way quickly, we need to put good environmental practice ahead of market fashions unless there is a compelling case that the market driven, short termist, 'money talks' solution can better deliver the environmental improvements required.
Sorry, but I don't buy any of these points. Unless the sustainable ways proposed fit with the market environment, they won't happen to a sufficient extent to be worthwhile.
:) We'll see.
For example, the United States is not signing up for Kyoto because they believe that to do so would damage their economy. The Chinese are not stopping building power stations, presumably for similar reasons.
Quite so, but none of this means we should do nothing.
The fact that much of the solution is not trivially delivered does not mean that the problem that needs addressing has gone away.
By all means try and find better ways to deal with the situation, but I don't buy it that 'business as usual' is the answer.
The environmental lobby needs to go away and learn some economic realities and then come with solutions that will allow sustainable economies.
This isn't some problem owned by environmentalists for their amusement.
It's a problem owned by all of us that all of us have contributed to.
Those will get the support that actually matters. Otherwise all of this is just pissing in the wind.
Wind and piss aside, I don't see that the scale of the problem absolves us from responsibility for our individual contributions to it.
Now we've got that clear, would you mind standing at our next local council elections so I can not vote for you please ? I think that what you may have got clear in your mind is what you would like to believe I have said. However, that bears no relation to what actually was said. Specifically please ?
Already covered in detail.
Well - if you thing there is a specific misunderstanding, feel free to share it, otherwise it is likely to persist.
