The solution is quite simple. Just require every company and person that emits co2 to pay for scrubbing it and let the market solve the problem efficiently. The only issue is getting everybody to agree to clean after themselves which practically guarantees this doesn't get solved until we are about to suffocate.

There is so many issues to solve in order to have a carbon tax. Just to pick a few examples:

People do not want their electric bill to jump ten (or more) folds just because wind production went down and now the gas turbine is burning, and they definitively do not want brownouts. Industries like steel and other high energy users is particular allergic to variance in power availability and price, and without tariffs it is practically impossible to demand it in a global economy.

Food prices would go up as rural living is directly impacted by carbon taxes. It used to be that the largest portion of a persons income went to pay for food. Today it is a rather small portion. Asking people to pay the carbon tax through increased food prices is a very hard proposition, and without tariffs it is practically impossible in a global economy.

Then we have urbanization where increased costs to personal transportation means a population that relies more on mass transit systems. That mean in order to keep people from moving to cities we need a significant investment into building out the railway system, which is the opposite what most countries has done in the last 50-80 years. That investment means raised taxes on top of the carbon tax. It also mean a increased strain on the infrastructure inside cities when density will increase while new infrastructure is being built, which mean more taxes.

Then we have international trade (air and sea transport) which is governed through international treaties. To be fair this is likely the easiest place to do a carbon tax as it would only effect all imports and exports and operate as a equal tariff for everyone, but getting people to agree to it it is a significant bigger hill than the Paris Agreement.

I think the most important benefit of co2 tax would be we would be much more conscious about emissions the same it happened to garbage couple decades ago. This is prerequisite for business to include it as a real factor in optimizations. And if you are one of those that do not care you would still have to pay for cleaning after your.self

I think discussions could get more constructive if proponents of CO2 tax did get conscious of the epycal change they are talking about.

Same issue as protecting environment from garbage and toxic substances or replacing our use of oil and gas with renewables. It costs huge, nobody had incentive starting it, but it is worth it.

The tax would have to be slowly introduced over period of many years. It is necessary for economy and various industries to adjust. New industry of scrubbing co2 needs funds and time to develop.

What does epycal mean? (Or what word did you mean?) Google failed me.

Kind of. Actually many high energy users like steel industry are often the primary clients of demand-response agreements with their suppliers. If it's in the contract and helps offset their energy costs then some variance isn't necessarily bad for their business.

>There is so many issues to solve in order to have a carbon tax. Just to pick a few examples:

All of your examples look like one issue to me, which is people unwilling to change their lifestyle and sacrifice their luxuries.

The only way out of this mess is to use less resources, which means consume less, travel less, have fewer children, etc. Carbon tax or dictatorial orders, the root of the problem is people don’t want to consume less, and our children and their children will pay the price due to us not wanting to pay it now.

Re:Flight risk: can we take the carbon out of air travel? by sokoloff on Tuesday September 03, 2019 @06:59AM (#20865338)
Of course no one wants to pay it now. To me, that’s an argument for forcing the payment (via taxation) rather than wishing really hard that people will change.

Getting people to accept increased food prices, higher cost of imported goods and higher taxes in order to focus on infrastructure is complex. To make a comparison, universal healthcare is a rather minor governmental change.

To put down some numbers, Americans spend just 6.4% of their household income on food. Around 1950 they spent about 20%. It not that Americans eat one fifth as much as they used to (if anything the claim is that people eat more today), so the life style change is both that people need to pay more and eat less.

Similar if we talk about railway budget, the US government spend today about 0.00156% in proportion to the budget of 1950. It basically stopped investing into the railway infrastructure. Naturally the proportion of the population (and industry) that use the railway system has also gone down, through not as extreme as the budget.

The root of the problem is that people don't want to pay more to get less, and then also consume less at the same time. They also don't want to pay more taxes in order to invest heavily in infrastructure that take half a century before people see the benefits.

Confirm that it's 1/640th of the 1950 budget?! That seems insane. (Is it perhaps 1/6.4 [0.156% or 0.00156x] instead?)

The Federal Railroad Administration alone has a budget over $1.5BB. Does that mean we were spending the equivalent of almost a trillion of today's dollars a year (~25% of receipts) on rail in 1950? That seems several orders of magnitude wrong.

Re:Flight risk: can we take the carbon out of air travel? by belorn on Tuesday September 03, 2019 @12:52PM (#20868500)
Yes, a 1000x error there :).

The numbers I read was that since 1950 the railway infrastructure budget has only increased by 30%. US budget in 1950 was around 70 billions, while 2018 it is 7 trillions. (https://www.usgovernmentspending.com/fed_spending_1950USbn)

The proportional funding should thus have went down by basically the same amount as the government spending went up. I might very well be wrong, and The Federal Railroad Administration was created in 1966 so I am not sure exactly which part of the government paid for railway before that point, and the 30% claim could of course be wrong. Department of Transportation has had a increase in funding by about 10x from 1970 to 2008, but I could not find exact numbers for the Federal Railroad Administration.

I agree with you this is a very important issue. But it's far too easy to underestimate the "stubborness" of people to keep living fine!

You make it sound like these unsolved, expensive, or insurmountable issues.

Literally all of these have cheap, trivial fixes that would reopen markets closed by the perverse subsidization we have now.

> People do not want their electric bill to jump ten (or more) folds

Power companies already offer budget billing to deal with the seasonal variation. It's trivial to extend this to some level of weather prediction. In fact there's already source variation taken into account. Even if the increased volatility causes the order of magnitude price changes, there is already a market for electric price smoothing through batteries and energy storage. Just look what Tesla did for this exact issue in Australia.

>Food prices would go up as rural living is directly impacted by carbon taxes.

I'm not sure how you're figuring this. If anything, food prices would decrease because we'd find more efficient local distribution techniques. Since rural areas is where the foo dis grown, that's where it would be the cheapest. In fact we not only already have more local distribution channels - we have federal infrastructure around it: https://www.ams.usda.gov/local-food-directories/farmersmarke.... Moreover, there's already a growing free market for this: https://fortune.com/2015/08/21/local-food-movement-business/.

> increased costs to personal transportation means a population that relies more on mass transit systems. That mean in order to keep people from moving to cities we need a significant investment into building out the railway system

I'm not following this argument. Increased reliance on mass transit would overall make everything cheaper, AVOIDing massive investments in both railroads and increased highway capacity.

I also don't follow your last point. Tariffs don't require treaties and are probably the best place to solve this in the beginning. As more nations enact their own carbon tariffs, we could begin to have a real discussion on international agreements.

"At present there are no proven technologies capable of large-scale air capture of CO2. It has been suggested that, with strong research and development support and industrial scale pilot projects sustained over decades, costs as low as ∼$500/tC may be achievable [226]. Thermodynamic constraints [227] suggest that this cost estimate may be low. An assessment by the American Physical Society [228] argues that the lowest currently achievable cost, using existing approaches, is much greater ($600/tCO2 or $2200/tC)."

So that's $600+ for an NY-SF round trip - in decades time. Currently we would have no flights at all.

Re:Flight risk: can we take the carbon out of air travel? by cmutel on Tuesday September 03, 2019 @06:18AM (#20865159)
As far as I understand, current state-of-the-art is between $100-200 per ton CO2 (see https://www.cell.com/joule/fulltext/S2542-4351(18)30225-3). This is from the CO2 capture company Bill Gates has invested in, FWIW.
Re:Flight risk: can we take the carbon out of air travel? by lozenge on Tuesday September 03, 2019 @06:50AM (#20865290)
Yes, multiply that by about three to get the cost per ton of carbon then add the cost of sequestration - your paper only includes the initial capture.
Re:Flight risk: can we take the carbon out of air travel? by lmilcin on Tuesday September 03, 2019 @05:43AM (#20864997)
Well, this would definitely be phased in slowly. While phasing in, the technological side would be getting better and better as companies providing scrubbing would be building capability and competing to do it cheaply.

Also take in mind the problem might be solved in a different way, for example people switching to high speed trains for shorter rides, business meetings conducted remotely or people choosing more local travel destinations or alternative ways to spend free time.

The important part is to factor in all costs of products and services into their price, keeping environment clean included.

I agree. Get an international body with 50% +1 voting rules, proportional to people represented (say, 1 for every 5e6 living humans, including minors). Get a carbon certificate system up, where there is exactly 1 way to create certificates: permanently sequester carbon dioxide from the atmosphere. I.e., grow plants, char them, and bury the coal deep enough to convince the international carbon committee that the cover won't erode for some minimum time (something above 1e7 years, I'd suggest), or something as effective. Find a way to sanction local governments that don't enforce the need for carbon certificates when digging up stored carbon/burning down (old?) forests/etc. . I think mutual economic sanctions against the local government by way of a full (Maybe except imports of basic grains and such into the offending area, if the international carbon commission deems them at risk of famine otherwise. Also medicine and medical equipment deemed essential. Possibly with international ground troop supervision/fact-checking in cases where abusing the embargo loophole would be significant, i.e. spare electronics.) trade embargo between the offender and the rest of the world. There might be reasons to use a selective embargo instead, which allows imports of technology for zero/net-negative carbon industry, along with 1:1 export quotas to pay for the imports. Likely coupled by way of 1:1 exchanges of container loads, i.e. export this heap of containers, in exchange for importing this heap of containers with "green" technology/medicine/food, but no money changing hands there.

To be fair though, it might actually be possible to found the international carbon commission in a technocratic way, obviously without any way to enforce anything at the start, but a sort of small founding group that serves to organize the first year/first years of meetings, building the physical place, managing funding from the benevolent technocrats, etc.
