The tricky plan to pull CO2 out of the air

Will carbon dioxide removal work? It has to.

In recent years, over 70 countries have committed to net-zero carbon emissions, aiming to become carbon neutral by mid-century. The 2015 Paris Agreement aimed to keep global warming below 2 degrees Celsius and ideally limit it to 1.5 degrees above pre-industrial levels. Despite global efforts, emissions are still rising, and achieving the 1.5-degree goal has become increasingly difficult.
Most pathways to keep warming below 2 degrees, and eventually return back to 1.5 rely on negative emissions, which involve pulling carbon dioxide from the atmosphere using carbon dioxide removal (CDR) methods like enhanced weathering and direct air capture.
However, these techniques are still in early development stages, and require land, energy, and money. Critics argue that relying on CDR implicitly encourages governments and companies to postpone necessary emissions reductions because counting on CDR now means relying on future generations of leaders to deliver on those promises. Preventing emissions is broadly less costly than cleaning them up after the fact. But even with dramatic cuts to emissions, experts say some amount of CDR will still be necessary.

Artificial CO2 removal isn't a technology that is currently viable in any way unfortunately. Don't let big-oil convince you otherwise.

[@SomeKidFromBritain]

If it were viable, would you support it?

[@lordofwarlk]

@@SomeKidFromBritain lol, i dont understand, its just a engineering problem, either it works or not. its not an opinion. Are you against cleaning the air? its not the point. the point is viability as a solution for the problem. which in the current state, it is not. is it hard to compreend?

[@pioneer_1148]

No but that isn't the point. No it won't allow us to keep burning fossil fuels and no it's not practical to just offset everything. However, current predictions say global warming is already at 1.2 degrees Celsius and it's predicted that it will reach 3.2 degrees Celsius at the current rate of decarbonisation we need much stronger measures to accelerate that decarbonsiation, most effective would be a carbon tax. But in the long run there are both industries such as long distance air travel which are near-impossible to decarbonise (short distance can and likely will be electrified but the energy density of batteries is far too low for anything beyond a few of hundred miles), where the best solution will likely be to require airlines to pull as much or more carbon from the atmosphere as they emit. Additionally in the long run we will want to pull the carbon which has been and will be emitted out of the atmosphere and to do that at scale we need the technology to be mature, which means we need to start development now.

[@peter_parkour]

​​@@SomeKidFromBritain I think anyone reasonable would. The problem is it's a hypothetical solution to a very real and imminent problem that already has real solutions. The only thing preventing those solutions right now is that it would affect profit of companies that majorly contribute to the problem, and require everyone to put their guns down in a very volatile global political climate.

[@SomeKidFromBritain]

To all of you, in a scenario where carbon capture can be demonstrated to function effectievly, It must be used. We could go net zero tomorrow and we still need to pull co2 out of the air. Godspeed.

[@bidaubadeadieu]

Carbon capture has another big problem not mentioned in the video: CO2 is not the only pollutant created by carbon intensive heavy industry. Only capturing carbon leaves poor communities located next to factories stuck with all the NOx, PM2.5, and other toxic products that aren't captured.

[@businesszeus6864]

CH4 is the worst one of all

[@jp4431]

You're not wrong, but the focus of this video and carbon capture is on attempting to reverse global warming caused by CO2. Those issues you mentioned are not problems associated with the technology. You might as well say, "the issue with heart surgery is that it didn't get rid of my cancer and diabetes". That makes no sense.

[@Hopeful100]

The first lie I remember my government telling me was twenty years ago when the UK pledged to net zero by 2020. That goal just got pushed back another thirty years. I wonder if in 2050 they'll all say "We promise to hit net zero by 2100"?

[@trader2137]

even if they do, you should be happy about it, going net zero is just waste of money that can be spent on something more useful...

[@fyzxnerd]

Maybe I missed the part where they talk about how many of the carbon capture technologies require more energy than they save and that was rolled up into the "we gotta turn off the tap" line.

[@davidmeier2014]

Carbon capture technologies don't save any energy, but they can be carbon negative if we use renewable energy to power them

[@benjaminmcintosh857]

I guess the thinking in those cases is that you're supposed to power them with renewables

[@aliancemd]

Also, it doesn’t mention that Oil companies are the biggest investors in this technology. They are promoting carbon capture instead of renewables, as a way to profit on the other end

[@andrews2727]

CDR does just seem like an excuse for companies to not have to turn off the tap, or in some cases even increase the amount coming out if they think they can "buy down" their emissions for a lower cost than what they can make by increasing emissions

is that a bad thing? if they CAN buy down emissions (seems prohibitively costly though) then let them emit as much as they want

Nature stubbornly refuses to accept USD or any other human currency.

[@critiqueofthegothgf]

@@swank8508 yes, it's a bad thing. continuing to use fossil fuels and non renewable energy just because 'we have methods of removal' doesnt suddenly become good. that's a quick and easy way to stay carbon neutral for hundreds of years, or even worse, regress back to carbon positive

[@lattyware]

I think it's super dangerous to present it as a real option. We just don't know if it is viable, and the fact we are already relying on it in our plans is just a way to launder saying that we won't hit our goals. We need to be realistic about how badly we are doing, otherwise we'll never actually do what we need to. Not to mention that this is yet another way for extremely profitable corporations to push their costs into externalities we all have to pay for.

[@lattyware]

And to be clear, that isn't to say we shouldn't *try* to make it work, just that relying on it working is wrong, and any costs should be weighed against just investing in more reliable existing options.

[@avinashreji60]

[@Greentrees60]

@@lattyware there is no scenario where it isn't a real option. I don't say this as a booster of the tech, but saying that we can rely on anything else to avoid extraordinary harm is false. I know that makes me sound like one of those nuclear advocates who demand we rely on that particular tech (or any other tech, I just hear nuclear advocates say stuff like that a lot). But there are no scenarios which do not contain this - since the 5th assessment report carbon sequestration has been part of the projections for 2 degrees and 1.5 degrees. It's really unfortunate that we're trusting something that doesn't exist to save us, but that's our only option.

It would be interesting to know if the companies pursuing CDR and ESG status, how many of them operate primarily in buildings with LEED Platinum Status? There are concerns with LEED don’t get me wrong, but that system at least tracks emissions from cradle to grave and has a qualified standard by which to gage the environment impact and benefit of buildings that tenants occupy. Course tenets have to pay a heft premium for these builds, but it would mean a lot more if companies are willing to pay out a 400% premium for structures to occupy on the front end than to promise futures of CDR without ever actually making that investment.

Hi, I loved the presentation, but I must say I have a few notes and requests. With planting trees, the young can’t quite capture the same amount of CO2 that older trees can. And the older trees also emit more CO2 once dead. I’d love to hear more about how forest protection is equally important as reforestation & what’s happening around the world regarding that. And the other point is the continents most responsible for CO2 emissions. Is it really the countries or is it specific companies? How is CO2 emitted, what’s the root cause? Who are the biggest players? I’m sure some other channels (like The Story of Stuff) have already touched on these, but maybe we need to get the emitters to be more accountable by mentioning them.

[@sandrafrancisco]

young trees also don't take as much space as old trees so it probably balances out. young trees also won't take as much energy to cut down, process into biochar, and bury.

[@arthurschildgen5522]

Big friggin problem: The massive amount of energy that it takes to remove that teeny tiny bit of CO2 is just going to lead to more demand for fossil fuels, so this WILL make the problem worse.

[@Orangeking05]

Yep

[@kaitlyn__L]

Ideally they’d only run when there’s excess renewables production. Second best would be hooking up small nuclear plant to provide exclusive power for the machinery. Cheapest would probably be powering it with oil and gas so, sadly, that seems the most likely.

[@arthurschildgen5522]

@CarlosT No, because all that clean energy could have gone to offsetting fossil fuels on the grid. Supply of solar, nuclear, etc. is as of yet limited.

[@nickmangia-forestry]

Big part of sequestering forest carbon is that you have to do something with the trees. A tree falls in the woods, it rots and releases Co2 back into the environment. You harvest timber in a sustainable and silviculturally sound way, then you get products that store Co2 in them. Ideally for this you want structural and architectural products that are durable and last hundreds of years. Not toilet paper and fast fashion construction.

[@puckelberry]

Exactly, plus the trees we plant are very fast growing and typically monoculture and nonnative further disrupting ecosystems.

[@Ninjaeule97]

Well, when you plant a forest in an area that didn't have one before even if one tree dies and releases it's carbon back into the atmosphere another one will take it's place and capture it again. The problem is we are currently cutting down more forests than we plant.

[@girak2]

Not all of that tree's CO2 has to be released. Soil has a huge capacity to store carbon, hence the no-till movement as an effort to reduce climate change.

[@michaniedzielski1455]

but some of that carbon from the trees stays in the ground, and treed are the most efficient in comparison with the CDR technologies ( and it doesn't require additional energy )

[@Greasyspleen]

Sounds reasonable in principle. But in practice... what can be mass-produced and also last hundreds of years?

[@nestorvargas2399]

In chemistry labs, there’s something called green chemistry which focuses on using renewable resources to make reactions rather than use many chemicals for the starting reactant.

The economic argument for sequestration misses the point entirely, because they don't run on dollar bills, they run off electricity, and that energy even when it comes from renewables takes away from other uses of that energy. When a company pours billions into sequestration in the US, while India is building coal plants because they don't have cheap enough access to renewables. They're not being "socially responsible", they're acting in the interest of their rich friends.

[@isabellacatolica5594]

Replacing a coal power plant with something like a nuclear power plant is easier than done in India. India has come a long way, but the construction industry is inefficient and investors are still hesitant to invest due to political instability and overbearing regulations regarding the industry.

[@SkywalkerWroc]

Planting trees is at-best CO2 neutral in the long term, realistically: It's only adding more CO2 to the atmosphere. Before you even plant a tree at its location, you already expel several kilograms of CO2. Then tree grows - captures a few tons of CO2. But after death it doesn't get sequenced into carbon, rather it is used for products that end up roting in waste yards, if it isn't burned directly for heating. And everything between tree being cut down and turning back into gases and ash involves tons of CO2 - the more there is between final remains of the wood being turned into underground carbon, the more CO2 gets emitted. And even in a fully natural environment, without any human activity (which barely exist in Europe or US), majority of the mass of the dead tree is expelled into atmosphere at one point or another, from roting to cow farting off last atoms of carbon re-used by other plants that grew from that dead tree. In nature very, very little of the dead tree actually remains underground. That's why it takes hundreds of thousands of years to accumulate even 1 centimeter of rock.

[@AntonAdelson]

@@SkywalkerWroc Everything you said can be fixed. Trees can be composted. I have friends who already bury logs for compost. Also, "Before you even plant a tree at its location, you already expel several kilograms of CO2." - what do you mean?

[@SkywalkerWroc]

@@AntonAdelson Composting turns around 20% of the mass into CO2 and methane, but there are also numerous other byproducts, notably NOx (the poisonous gas that diesel cars emit). And if you use the resulting substrate for anything else than to bury it underground - in the end it's emitted into the atmosphere in up to 99% of the mass. "what do you mean?" - I mean that you don't teleport seeds into the field, even if the only CO2 emitting thing you do is transporting them by car - it's still CO2. And stuff like growing the seedlings also has associated CO2 emissions (e.g. plastic pots, moving stuff around, delivering water, etc. etc.) - all in all it's several kilograms of CO2 quite easily.

[@Ninjaeule97]

CO2 capture/removal only makes sense for things like concrete where emmisions aren't avoidable because of the chemical reaction that happens during production and once you stopped emitting CO2 in the first place. Direct air capture takes energy in the form of electricity, so even if you power it exclusive with green energy that electricity could have been used to replace fossil fuels in the electricity grid instead. Which means you didn't actually remove any CO2.

[@anustubhmishra]

that's not necessarily true though if lets say with 1 mwhr of fossil fuel energy 10 tones of co2 is produced while using carbon capture 1mwhr of energy 100 tones of co2 can be removed from the atmosphere it would be better to remove co2 then to not. but at least right now its way better to not produce co2 in the first place and use renewable energy to replace fossil fuels

[@shapelessed]

@@anustubhmishra First of all - Current state of the technology consumes more CO2 equivalent of energy than it removes. Second - It's not anywhere near things people would invest in, as it does not produce any profits, and that's what is driving the economy, so don't count on that. Third - This is a "solution" fuel companies came up with and are actively promoting to protect their busines. And to add a cherry on top - CO2 is not the only gass that's produced by burning fossil fuels, in fact lierally all the other ones are those we shoud be worried about. CO2 could easily be handled by all the trees growing all around the world if we weren't actively chopping them down. CO2 capture will NOT happen unless mandated by a government, and even that is unlikely to be done in any proficient manner.

The problem with carbon capture is that its energy intensive and long term storage could become disastrous even if the tech was viable. You need to prevent any leak or chemical interaction which release CO2. The reason why trees aren't a great solution is that they get broken down by fungi etc which releases all the trapped CO2. The reason we have oil and coal to begin with is all the trees that became the fuel were during a period where microbes couldn't break down lignin allowing the trees to be buried and fossilised.

a few things to keep in mind: IF the nationally determined contributions pledged at the Paris agreement are met we will likely achieve 3.2°C of warming by 2100. In 2018 it was calculated that to have a 66% chance to keep emissions at 1.5°C by 2100 the total amount of CO2 that can be emitted was 480 Gt of CO2. That means achieving carbon neutrality by 2030, not 2050. Of course if you lower you probability to 50% you end up with a larger carbon budget and hence more time to achieve carbon neutrality, that is why estimates that can be found online vary widely. Of course because of the historical responsibility of the Global North in CO2 emission, the North should have achieved carbon neutrality well before 2030.

[@brady9592]

From the recently published article in Nature by David T Ho about carbon dioxide removal: “… think of CDR as a time machine. Take the proposed US DAC hubs, for example. Each facility is eventually expected to extract one million tonnes of CO2 each year… for every year of operation at its full potential, each hub would take the atmosphere back in time by almost 13 minutes, but in the time it took to remove those 13 minutes of CO2, the world would have spewed another full year of CO2 into the atmosphere. Meanwhile, if everyone on Earth planted a tree - 8 billion trees - it would take us back in time by about 43 hours every year, once the trees had matured. The time-machine analogy reveals just how futile CDR currently is. We have to shift the narrative as a matter of urgency. Money is going to flood into climate solutions over the next few years, and we need to direct it well. We must stop talking about deploying CDR as a solution today, when emissions remain high - as if it somehow replaces radical, immediate emission cuts.”

[@henryfarber4014]

The problem with CDR is that in order for it to work it can’t make any emissions in the process of removing carbon or it would pointless. And since long term cdr storage is only viable in certain geological conditions, there is a very tiny portion of the world that can actually do it. Otherwise you’d have to transport those emissions to places where they can be stored. CDR is just another way to pretend we’re actually making a dent in climate change but in actuality it may make it worse. Because just like with carbon offsets cdr gives a false sense of security that may make companies emit more they normally would. And since cdr isn’t that efficient you can see how we’re actually making the climate crisis worse by doing things like cdr and offsets. The solution to climate change is not to greenify our current rate and scale of production it is to simply reduce it. Infinite growth on a planet with finite resources is not possible.

The bathtub metaphor is a wild, dangerous oversimplification of how CO2 in the atmosphere affects extreme weather caused by climate change. CO2 in the atmosphere causes more heat which is more like more momentum. More heat, more evaporation (drier, wildfire prone land), more water moving (heavier rains elsewhere including floods), stronger winds because of more moisture moving leading (more frequent and more intense tornadoes and hurricanes). Weather has inertia, and just removing CO2 will not immediately stop extreme weather events already in motion, though it will help prevent them from getting more extreme. So we still need net zero and CDR, but its not magic that will save us and is a dangerous distraction from substantive net zero changes. Also, pollution and non CO2 GHGs are still a thing....
