driving 15k miles @25 mpg = 600 gallons of gas (15,000 / 25)

gallon of gas has 19.60 lb co2 / gallon [1] = 11,760 pounds of co2 (600 * 19.6) = 5.88 tons (19.6 * 600 / 2000)

cost for clime works to sequester co2 is $600 [2] so total cost to sequester for the 15k is $3,528 (5.88 * 600)

cost to sequester per gallon is $5.88 per gallon ($3,528 / 600 gallons)

price of gas in NYC is $3.11 per gallon so new cost per gallon factoring in the current high cost of carbon capture is $3.11 base price + $5.88 to sequester = $8.99 per gallon

yeah your math seems great lol

assuming cost to sequester goes down to $100 per ton, the cost for 15k of driving at 25mpg would be $588 (5.88 * $100), cost to sequester per gallon would be $0.98 so the new price of gas in NYC would be $4.09 (3.11 + .98), actually not absurd given recent trends and probably not high enough to discourage people from driving

(Discouraging people from driving is not the point, if we have net zero CO2 people can drive as much as they want.)

There's still lots of pollution coming off of tires, but that's just a health & environmental hazard, not a climate hazard.

That happens whether you drive a tesla or not. Probably a lot more if you drive a Tesla. A Tesla Model X weighs 30% more than a BMW X3.

Extraction and refining of oil is still quite polluting. The first step is still reduce
Re:The dream of carbon air capture edges toward reality by garyrichardson on Thursday August 26, 2021 @08:50AM (#28314272)
Agreed. BUT if we price in the true cost of carbon at all levels it balances out. In a world we’re there is sufficient DAC you could charge the extractors and refiners and delivery companies and consumers. The price of a unit of gas goes way up at that point. Take the original commentor’s guess at $10/gallon - is the new cost $25 or more? I think we’d get to reduced consumption quickly.

Oh, that’s only net zero. In this fantasy we should also charge fossil fuel industries for past infractions too - maybe they need to pay an extra 20% for extra dac capacity.

Re:The dream of carbon air capture edges toward reality by FeepingCreature on Thursday August 26, 2021 @06:02AM (#28312766)
I personally disagree that's a good step. Sadly, I can't think of a good memorable three-worder involving "price in all external costs" and "stop moralizing at people". Increase, internalize, improve?
Re:The dream of carbon air capture edges toward reality by afiori on Thursday August 26, 2021 @08:20AM (#28314000)
The reduce part is not that it is wrong to consume, there are many ways in which cars are useful, but if your purpose is to be "green" it is still the first step, for many people it is not an option and that is ok.
Re:The dream of carbon air capture edges toward reality by FeepingCreature on Thursday August 26, 2021 @08:24AM (#28314048)
I mean, I don't think it should be up to individuals to be "green"; there's lots of individual choices but "price in the damage your actions cause" should not be one of them. And once environmental damage is correctly priced in, then reducing consumption is no longer green anyways, because the consumption is now carbon neutral.

>once environmental damage is correctly priced in, then reducing consumption is no longer green anyways, because the consumption is now carbon neutral.

Global warming is only a subset of environmental damage.

There's all kinds of other damage in the wake of over-consumption.

When you kill more trees than you grow back, the devastation comes much quicker than waiting for the whole world to get hotter.

Carbon can be looked at as only one material and IF it can be been made neutral in the face of rising or even curtailed consumption, that seems to be the pricing that can be correctly assessed to compensate.

To raise the ante and try to price in many other forms of environmental damage too, you're going to need a bigger bank.

Plus just to earn all that money to allow all that consumption leaves an additional trail of damage behind, with a departing path of financial acumulation leading off in the opposite direction.

And as we know, different currencies have different toxic footprints themselves, and that was before bitcoin which has gotten into a category of its own.

Gemstones and rare elements too, some are bloodier than others. Deaths here can occur faster and sooner than forests are dying.

To me this tends to indicate that reducing consumption will always be green.

There is an interesting discussion to have around whose behaviour is of an higher priority and/or which group has more blame, but regardless of that individuals can still contribute.

The problem isn't individual action, but focus on individual action as a substitute for government action.
Re:The dream of carbon air capture edges toward reality by slashdot2008 on Thursday August 26, 2021 @12:30AM (#28310727)
thanks for plugging and chugging it all out.

carbon engineering's carbon capture technology is projected to be significantly less than $600 tonne, they say the plant they are building for occidental petroleum in texas will be profitable from 1) cost of avoided CO2 purchases (CO2 is used to pump oil out of the ground) and 2) california CO2 credits for "low carbon oil" which is between $175 and $200 USD/tonne [0].

so if carbon ends up at $200 per tonne instead of $100, cost per gallon would be $3.11 + $1.96 = $5.07. If you drive a lot probably enough to nudge you towards an EV!

Re:The dream of carbon air capture edges toward reality by seiferteric on Thursday August 26, 2021 @01:00PM (#28317511)
I think this is an overestimate because DAC is so inefficient when there are so many sources of higher grade CO2 emissions, both natural and man made that could be captured well before DAC makes any sense. Why would we bother doing DAC when you could capture streams of nearly pure CO2 from factories or even volcanic seeps etc?

Good luck getting Congress to pass a tax increasing the price of gas by 1.33-3x. That's political suicide, even for Democrats. Directly fucks over the working class but corporate fleets can afford to pay the extra $$$ or switch to electric.
Re:The dream of carbon air capture edges toward reality by gorkish on Thursday August 26, 2021 @01:00AM (#28310879)
This is not out of line with the price of fuel in some countries already; I think it demonstrates that the technology is quite possibly on the edge of economic viability for closing the carbon cycle of gasoline, even if we don't get hundredfold improvements in the technology. That's pretty good news for everybody.
Re:The dream of carbon air capture edges toward reality by filleokus on Thursday August 26, 2021 @05:50AM (#28312683)
In Sweden we're around the equivalent of 7.2 USD / gal, due to high taxes.

However, and I expect this to be the case in most European high-taxed countries, the taxes are just fed in to the general tax revenue of the government. Not ear marked for e.g capture programs.

These taxes do of course fund some inovation projects etc, but I think it would be a hard sell politically even here to direct all carbon-related taxes directly into buying Co2 capture.

For example, as renewables have grown larger in Sweden, the government has started taxing the production of solar power on larger installations (≈ roof of a warehouse), even if the energy is never sold/transmitted to the grid.

UK petrol is about £1.30/liter = $1.80/l = $6.80/US gallon. Not really enough to seriously deter driving yet.
Re:The dream of carbon air capture edges toward reality by raffraffraff on Thursday August 26, 2021 @04:59AM (#28312349)
The biggest problem with any cost-driven incentive is that it has the ability to fuck people over. If you make electricity too expensive you end up with fuel poverty. There is no way out of it. There is no other 'choice' that poor people can make. Same with water charges. What do you do if you can't afford your water bill?

But cars are different. For many people, driving is not essential. It should be a luxury to drive a huge hunk of metal around a smooth road. By right that shouldn't be affordable, given the current situation. We just got used to cheap cars and cheap fuel, and built our culture and our cities and our lives around that. (Yeah, I know, people who live in the country are married to their cars). If your country really pushes EV charge points and implements tax incentives on EV vehicles, then you are providing people with a way out of high carbon tax. And you need your PR campaign to be clear that people are getting a choice: high price fossil fuel or cheap EV. Because the chicken/egg here is that you won't get a government that'll make those changes until your convince people to vote for it. And people won't vote for poverty, but they will vote for options.

If you create a tax that disproportionately hits poor drivers, you can balance that out with redistributive taxes - and incentives for buying electric cars that mainly benefit poor people.

Currently most incentives for buying electric cars benefit the wealthy. For example in the UK, I can get 45% of my tax back through salary sacrifice on an electric car, whereas a person on basic rate only gets 20%. It should arguably be the other way around i.e. a "super deduction" for the poor, capped at basic rate relief for the rich.

Re:The dream of carbon air capture edges toward reality by zelphirkalt on Thursday August 26, 2021 @07:01AM (#28313194)
A cost driven incentive can still be viable. It needs to be accompanied by practical replacement solutions. For example, if driving cars becomes too expensive for people, then public transport needs investments and needs to cover more ground, to help people out.
Re:The dream of carbon air capture edges toward reality by willyt on Thursday August 26, 2021 @07:52AM (#28313700)
Yep. I think they need to implement a "Fuel cost equivalent tariff" on public transport. FCET because everyone switching from a car needs to do this gradually so you can't include the depreciation etc because they are sunk costs. It costs me ~£65 for 50l of fuel which gets me about 450-500 miles in my car. If I'm travelling alone I should be able to buy a walk-up train ticket for that price, with a 20% discount for pre-planning my journey. If I'm travelling with my family then group tickets should be discounted so each extra person is a nominal extra amount as long as we all travel together. Tickets should be integrated across all transport modes like they are in Switzerland.

The big problem with this, in the UK at least, is that the trains are already full even though they are much more expensive than this. We really need more capacity but the hugely corrupt debacle that is High speed 2 is going to turn people against building better public transport.

So you'll pay to bulldoze people homes and build massively dense downtown housing that offers a better quality of life than the suburbs?

Re:The dream of carbon air capture edges toward reality by BldgPlrBr on Thursday August 26, 2021 @10:20AM (#28315318)
That is why the proceeds of such a tax should be given back to the population directly. That way if your CO2 emissions are average, it's a net zero financially for you but you're incentivized to reduce your emissions as you could actually gain money if you go below average (in effect it would mostly be the rich that lose money as they're quite often the biggest CO2 emitters).

However the implementation of such a tax, although conceptually simple, is practically very complicated.

Re:The dream of carbon air capture edges toward reality by diggernet on Thursday August 26, 2021 @11:50AM (#28316492)
If you give it back to the population, then you can't use it to pay for sequestering. That prevents doing something about the problem, and just brings you back to "pay to pollute".

If we started doing that in 1990 or so, after the first couple of climate summits we could've spread out the change over two or three generations. Now it hurts a lot more. If we wait another ten years, it will be even harder.

Not if you used that money to directly transfer that wealth to working class. All the money they've paid would return to them, in addition to the money paid by those corporate fleets.

But, in USA, it would surely go to military.

The carbon cost of 1 litre of petroleum is 2.4kg. You need to factor in the emissions through the entire production and distribution chain.

Not doing that is like comparing emissions to electric vehicles whilst assuming a carbon cost of 0 for the electricity.

EVs' lifespan matters (I'm not sure how it compares to ICEs today): if after a year you then sell the car as used, that's a significant amount more efficient than assuming the car is destroyed each year.
