You're not supposed to. It is a marketing ploy from oil and gas companies to shift the blame from corporations to individuals for their pollution.

We could have prevented climate change with nuclear power in the 1990s.
Even without solar and wind (they were too expensive at the time) or carbon taxes, Sweden and France managed to get emissions down to 5 tons per capita with old nuclear and hydro technology. If all rich countries had done the same thing, climate change would have been a non-issue.
We can still solve it today with today's technologies: solar, wind and battery technology has evolved and become affordable. Carbon taxes are politically feasible. And old nuclear technology is becoming more acceptable and gearing up.
Sure, try to help by reducing your energy use where possible and investing in things like home insulation and energy efficient heating and transportation.
But the actual big things that need to be done can only be done by politicians, to force economies to change.
Even without solar and wind (they were too expensive at the time)
This is true and I'm not disputing this fact, but had the oil companies not interfered with and killed off any attempts at alternative energy sources, things may have been quite different.
I’m curious how mass nuclear energy adoption in the 90s would have offset the impact of agriculture, livestock, and the oil and gas industry. I don’t see how nuclear energy would have made climate change a non-issue.
Then you should do the math. If the rich countries all had achieved 5 tons per capita in 1990, then atmospheric CO2 would be around 380 today instead of 420. It was 350 back in 1990 and reached 380 around 2005.
Sure, we would still need to get to net zero, but we could have gotten there over many decades without ever hitting 1 degree of warming. That's what I mean with "climate change would be a non-issue"
Cool. I’ll just do the math then. I’m sure it’s just as easy as all those people on Facebook say doing your own research is. Sorry, I don’t mean to sound flippant about this, but fuzzy napkin math without sources or stats or some kind of methodology does not make a strong claim. Without that kind of specificity or rigor, we’re just two assholes on the internet misinterpreting each others’ words.
Anyway, totally agree with that second paragraph. And I’m certain there’s a ton of sources to back you up on being at 1990s CO2 levels. I wouldn’t personally consider a few more decades of wiggle room to be a non-issue, that’s just me. Though, looking outside my widow at the hellscape of 100% humidity and melting assault I sure wish we had invested more in nuclear energy.
Nobody is going to get published in academia with a "what could have been" article. But there were a great many models published back in the 1990s and early 2000s on how to stay below 1 degrees warming. Nuclear power was the backbone of those models.
The economist did publish a nice fanfiction
What if nuclear power had taken off in the 1970s? from The Economist https://www.economist.com/the-world-if/2020/07/04/what-if-nuclear-power-had-taken-off-in-the-1970s
Neat! Thanks for the link.
Ammonia!
You see, a lot of the agricultural impact on CO2 concentrations on the atmosphere comes from industrial made fertilizers. Which is basically ammonia with a bunch of other things in smaller quantities. Despite being a natural product created by a ton of bacteria and organic processes, today almost all of the ammonia used by agriculture is produced by a chemical process that uses fossil fuels. Specifically extracting hydrogen from fossil fuel to then recombine it into ammonia. It also uses a lot of heat that comes from burning the fossil fuel. The thing is, we don't technically have to burn fossil fuels to make ammonia, there are other ways. But they require a lot of energy. However, if you have a lot of excess cheap electricity during low demand periods from nuclear power, for example, you can make cheaper ammonia and hydrogen. It's also cheaper and more efficient to keep a nuclear power plant rolling than to wind it up and down every day. So you can use the excess electricity to power or supplement other power hungry industrial processes like desalinization, hydrogen production, powering water reservoir replenishment pumping, etc.
This also offsets livestock production because a lot of livestock pollution is feed agricultural production. Almost half of agricultural production is for stock feed.
So, it would've helped, a lot, to have a non-fossil fuel energy source to feed a non-fossil fuel process path to fertilizers.
We’re burning these fuels and spending the energy on these sectors.
It’s mostly due to burning coal, oil and gas while expecting to get electricity, heat and motion out of it. Which sectors need to change urgently? Industry in general, road transport and buildings.
Yeah holy shit I can't believe that people are braking their head about this ...
Breathing does not create Carbon, it is only transformed.
There are basically 2 pools of carbon. The carbon already in circulation in the athmosphere, plants, animals and so on, roaming at the surface. That Carbon can be CO2, or other mollecules, but there is always a fixed amount. You breathing is simply borrowing the carbon for a bit and putting it out again in the air when exhaling.
The second pool is carbon locked away in the ground, as coal, oil and whatnot. That carbon is OLD and is not supposed to be in the first pool. When you burn oil, the carbon from the 2nd pool ends up in the 1st one. You cannot really offset it because even planting trees just transforms it as wood for a bit, but if the tree burns or rots, the carbon goes back in the air. The only option long term is to send the carbon back in a locked state in the second pool.
But for you, just reduce the amount of carbon you move from pool 2 to pool 1 to help the earth. Cut on oil, gas, coal as much as you can. The rest is basically irrelevant.
You can compare it to the water cycle. You are at a lake with a pump, and pump the water from the lake back into the lake. You can keep going forever and will not cause the lakes to rise since the water is pumped from there anyway. BUT, if a mega corporation starts pumping from underground sources and dumping it in that lake, it would overflow for sure. And they would blame you for all the water you are pumping.
This is a really important insight. To add to it: back when the carbon from Pool 2 was in the atmosphere, dinosaurs were roaming the earth and it was a lot hotter than it is now.
This is obviously a simplification, it but it drives home the point that once the carbon is out of Pool 2 it will cause global warming. The only way to stop that is to stop moving carbon from Pool 2 into Pool 1, ie stop fossil fuel mining.
Of course we could try to move carbon from Pool 2 to Pool 1, but it took the Earth millions of years to do that, and many of the plant species that did it are now extinct. Perhaps once we're exinct, they might evolve again.
Is there any way to bring carbon from pool 1 into 2? Or we already fucked up and have to live with it now?
Yes, carbon sequestration is the term for it, but none of them are currently practical to do on a scale that would mitigate the effects of the fossil fuels we burn. Growing trees is an example of this, as they do lock up carbon in the process of growing, but they're kind of a risky prospect since if the tree dies and rots or is caught in a wildfire then it releases the carbon again. Another option is literally just sticking it back underground in mines or oil wells, but of course that takes a lot of energy to do and then whole point of burning fossil fuels is to get energy so this one is currently a bit self-defeating. They're things that might be helpful to do if we succeed in transitioning to clean energy and have an excess of it available
If we can get nuclear fusion to work, that would be the kind of things that would then make sense to do. I can only hope that we figure it out as soon as possible.
As others have pointed out, individuals are not the problem nor are they the solution. How we produce energy and manufacture goods are the issue. The corporations producing energy and manufacturing goods don't want to change to sustainable alternatives because it will cost them money. So they've invented the idea of a carbon footprint to make it seem like it's your desire for electricity that is the problem and not how they generate it.
Don't say we because you're not part of it. You're the victim of it.
One thing that the carbon neutral concept overlooks is that the world is perfectly capable of absorbing the carbon output of a single person.
For average individuals we are not able to overwhelm the world with our carbon output. There is a carbon cycle and as CO2 increases in the atmosphere, plants grow faster and bring it back to a stable median.
It is massive industrialization that has overwhelmed the capacity of the earth to absorb the excess carbon dioxide created by humankind.
What you should do is spend your money on companies that have embraced carbon neutrality or being carbon negative, purchase items from low carbon companies, and be reasonable and responsible with your use of energy, including fuel and electricity.
When you have opportunities to vote for environmental initiatives, you should vote for them.
While you should be conspicuous of your carbon footprint in the environment that we have, you should also know that your ability to actually fix the issue is practically non-existent. The only thing that is going to fix the issue is government ruling that forces industries to stop polluting the environment at the rate that they are doing even if it causes our economy to decrease.
The only way for such initiatives to ever happen is if the population becomes carbon conscious and pushes for such initiatives. If enough of us do enough then the people in power will move to come towards us and make changes that will help keep them in power.
You're missing something: it's all a bunch of bullshit. So in a sense it's hopeless, but you've got to ask yourself why even existing makes it hopeless? Because the feeling of hopelessness you get is a lie. Someone wants you to feel like nothing is ever enough.
I'm not saying fossil fuels are not releasing CO2 and all that, I'm not a denier. My point is only that these new ideas about your carbon footprint, that come from eating food and breathing, are absolutely ridiculous bullshit. Carbon in the carbon cycle already does not contribute to your footprint. It's a lie to make you guilty when you didn't do anything. Youre being gaslit.
The only carbon that counts towards your carbon footprint are 1) fossil fuels that you consume, 2) plastics from fossil fuels that you dispose of (they may not be atmospheric carbon now, but they'll inevitably end up in the carbon cycle) and 3) your economic choices that lead to the destruction of natural carbon sinks, such as buying palm oil or products that contain it, Brazilian beef raised on torched amazon land, etc. You should not be concerned whatsoever about breathing and eating meat if your concern is carbon output.
Yeah, most people don't know that the carbon footprint concept was invented my BP... an oil company. Trying to push blame off them and onto the individual instead.
Congrats, you fell for the scam. Don't worry, we all did at one point. To be clear, I'm not saying climate change is a scam, I'm saying "it's all your fault" is a scam.
You're not supposed to plant trees like there's no tomorrow, but simply stop using fossil fuels. Simple as that.
Your respiration is already net zero. Plants capture CO2 to grow, you eat the plant, breathe out CO2, plants absorb that CO2 again. You should have heard about the carbon cycle in school. If not, look it up.
All the other emissions, the not net zero ones, are some form of fossil resource. Oil, gas, coal. You can't reasonably offset these, you just stop using them. There's no way around that.
Yeah it just kind of clicked for me that if I eat plants, that was net zero, but if I eat meat, there was another animal that had to emit CO2 (and other gases) at the same time as me before becoming food. So the opposite of plants taking my CO2 to become food, the animal emitted CO2 while becoming food.
What did you think, the animal ate? Oil?
Directly they dont but it does take oil and gas to make the fertillizer that feeds the crops and pesticides that prevent pests from destroying entire harvests, diesel to run the farm equipment and transport the crops to market. Modern farming, even organic, is very much Carbon positive.
Those animals ate plants op. Thats not where the emissions are coming from. At least not directly. Theyre coming from all the fossil fuels that were burned to run the farms and make the fertillizer used to grow crops that you and those animals ate. And realistically most of the CO2 you emit is indirect. i.e Production and transport of products that you buy. Even just drinking water from your tap required resources to be expended to purify, chlorinate and pump to your house.
In order to acheive a Carbon neutral or even Carbon negative economy, CO2 needs to be captured and the reality is that the steps that are needed to do this are not being taken. Industry is moving at a snail's pace and government has made no real attempt to either facilitate or force the level of change needed.
Those animals ate plants op. Thats not where the emissions are coming from.
Not directly, but if tons of biomass was chopped down and burned so those burgers could graze...
The world has its own CO2 cycle so it's not that we need to reach 0, we just need to reach a balanced emission threshold. Though at this point we will also need to aid this process with further removal.
The issue is mostly that we are outputting too much. Shipping industries, energy production, other transport such as cars and planes. These industries are a big part of the problem and the ones fueling (e.g. oil) them are the ones most interested in your feeling of hopelessness, as then they have free reign over their actions.
The world has and will get hotter. There will be more disasters. But it's unlikely to be the end of civilisation. The more we act now, the fewer people will suffer.
It's not a hopeless cause at all. Look at our tech now vs 100 years ago. Humanity has the means to do it.
- Folks generally don't consider offsetting their own breath, that's extreme.
- The vast majority of oxygen comes from phytoplankton in the ocean.
Offsetting your own breath seems unnecessary. A human being does not produce CO2 out of nowhere. It comes from oxygen, which we breathe in, and carbon which we eat. The food absorbs the carbon from the atmosphere when it grows, so taken in total the whole cycle is completely carbon neutral.
The reason CO2 concentration is increasing is because we're digging it up from the ground and releasing it into the air. Taking CO2 from the air and then putting it back a short time later is not really an issue.
Also, I'm really questioning OP's numbers here. The CO2 a person produces should be absorbed by about 15 trees, from what I can find. Or is he trying to solve the global climate problem with only potted plants?
Individual guilt is never gonna beat organized engineering.
You can't. You can't make your carbon footprint zero without a lot of money. That's thing though. There are a lot of people who have shittons of money who could not only make your footprint zero, but help make everyone else's footprint zero. These people, however, are often the ones who benefit from having non-zero carbon footprints. The rest are too obsessed with enriching themselves to spend the money to ensure their riches are still worth anything 20-30yrs from now.
There's a lot of greenery on Earth - seaweeds recycle a huge amount of CO2, as are all the plants we use and eat. It would be completely enough, especially as we keep killing off all the other animals that produce CO2.
It's just unfortunate that we're destroying the oceans too, and agriculture is a heavy industry with more polution. And while we kill off the harmless or useful wild animals, we replace them with livestock, and you know where that is going.
As individuals, we really can't do much in this regard. I guess you can do more biking instead of driving, reusing older products, buying local, stuff like that, but this really won't make a dent when industries keep using the dirtiest possible processes to save a cent, or if nuclear power keeps being lobbied out.
Last estimate was something in the range of three trillion trees, palms are probably not the most carbon dense tree for removing CO2. But all kinds of organisms help break down CO2 including Algae.
But don't think that your breathing is to blame for CO2, it's deforestagion, shipping, fossil fuels, war and bushfires are.
Make things, buy local and travel local.
How many extra trees do you need to offset the manufacture of that unnecessary CO2 meter?
That's why you buy a second CO2 meter and go measure at the factory the first one was built in. That way you'll know how many trees to plant for the two CO2 meters.
-
A quick Google search says there are 3 trillion trees on Earth. So that's 500 trees per person but as mentioned before things like algae and other sources make up more.
-
The carbon from your breathing is carbon neutral since all the carbon in your body comes from food which comes ultimately comes from plants. However the carbon dioxide used to produce and transport your food is where the excess comes from.
-
If you want to minimize your carbon footprint it's more about understanding which behaviors contribute the most. Eg an economy flight from the US to Europe is like 1.5 tons of CO2. That's like years of respiration.
-
Of course the problem is hard to solve as an individual. Maybe there just needs to be assignable liability for certain activities and the correct legal and economic system setup to optimize better for ecological issues.
Become a vegan activist and if you convince a few people to go vegan you can actually become carbon negative.
Also plant some trees.
CO meter for sure, but a CO2 meter? It's actually a good idea to have CO alarms in your house if using natural gas powered appliances. However CO2 is only a concern if you're in a hermetically sealed environment like a submarine or space ship. I suppose it could be useful to check proper ventilation in the home, but normally you can just open a window.
Anyway the Earth has a carbon cycle, in other words it filters natural CO2 emissions through environmental processes. The problem is the amount added by industry is more than the natural carbon cycle can process. So levels are steadily increasing.
When we talk about zero carbon footprint we mean sources from industry like driving gasoline powered cars, generation of electricity, and production of consumer goods. A good amount already comes from natural processes like volcanos and erosion so we don't actually need a zero carbon footprint, just need it low enough to avoid overwhelming the natural cycle.
At a personal level it would be just about impossible to have a zero carbon footprint. If you had a solar and wind powered home off-grid and used it to charge an electric car you could be well below average. However any consumer goods you use put carbon in the air to produce them. Even if you went full native you'd still be putting carbon in the air burning wood and candles.
Actually the CO2 meter showed levels in my home during the day at 1350 (I think over 1000 is bad - 10% cognitive decline I think occurs at 1500) and in the morning over 2100 in my bedroom! The AC turns off and the CO2 just builds up I guess.
I did the research to see if any amount of houseplants could offset it (nope), but yes, opening a window is exactly the solution. Problem is I live in Florida and it is way too hot to do that. So I compromised and turned on a bathroom vent all day and it is keeping the levels to around 800 per day. It basically is slowly sucking air through the not perfectly sealed home and expelling it through the roof.
But I recognize now my AC will have to work harder to cool the incoming air and make my home less efficient, thus doing worse overall. Happily we have a nuclear power plant here but still.
Surely this is satire?
Just try to act responsibly. Don't drive if you don't have to, recycle, start a compost heap. If you spend all day worrying about the "carbon footprint" of your own breathing then you'll just end up driving yourself crazy and blowing all your money on online scams
