Hi 👋 would a carbon tax work and what would be the best way to implement it? Also, another idea i had, that isnt really talked about much, is how convenience affects environmentally friendly decisions. For example, plastics and fast food are convenient, but really affect the environment and carbon emissions

This is one of the biggest reasons to preserve historic buildings: they have what's called embodied energy. Basically, if the building was already built, then the energy (and carbon emissions) of gathering its materials and constructing it have already happened. There's a much lower carbon footprint to repairing and maintaining a historic building than there is to tearing it down and building a new one in its place.

@@jonathantan2469 while that's largely true, historic preservation standards in the US almost never prevent utility updates. There's ways to update the electricity, HVAC, and plumbing. Not to mention that many older materials actually do preserve temperatures better than modern ones. Plaster and hardwood is far more insulating than studs and drywall. Vernacular architecture (building styles common to a geographic region) are also adapted to their local climates, like steep roofs in New England or wraparound porches in the South.

I'm sorry but i can't see any sense in your approach or at least i can see it if you confine it in no seismic areas with a low density of inhabitants. That becomes vernacular architecture, that i love. A huge chunk of countries, with their high urban density cities, are localized on seismic ground, from centuries or millennials. They have always fought against earthquakes to survive. Think about Japan, Italy, middle East. I really care about this problem but unless we are going to start building everything, sort of, with CLT technology, with all its limits, we still have to continue to use the best material on the market to assure the safety of infrastructure and buildings. The reality is that just research, technology and a less greedy market, could mitigate the problem. At the moment there is no solution at all. The energy efficiency of concrete constructions is pathetic, it's cost during the decades is stellar, the pollution caused by demolitions it's outrageous but... We could dialogue for ages about this topic.

I used to work as a chemical engineer at a cement factory in the united states. In the short 2.5 years I was there emissions were reduced DRASTICALLY. CO2 capture in the cement manufacturing process is actually one of the easiest methods to capture co2 with being able to use an electrostatic precipitator and a compressor you leave with almost 99.9% clean co2 which can then effectively be used in many other technologies. The problem is the sheer volume of co2 produced and the cost expected of cement makes it just not economical for the most part. The plant I worked in commissioned a carbon capture setup and ended up selling the gas to Praxair Which maybe is not the best way to handle it and it was for only a fraction of the total production. Even if the plant did fully decarbonize it would make the cement not price competitive with foreign cement(or even non-decarbonized domestic cement). I think the simplest and easiest solution would be to just subsidize carbon capture with carbon tax credits of some kind. The aggregate you presented based on the extraction of CO2 from flue gas(assuming a gas fired power plant capture or similar). Is something I haven't heard of before. I am curious on how the aggregatge preforms under shear stress, but as always more research is needed.
@shrill_2165

All due respect, the two solutions presented here are nowhere near good enough (though I know that's not what you were trying to make them out to be). You mention that factory curing inhibits the applicability of the first one, but that's quite an understatement. While I would probably endorse a cultural shift to less (but not none at all) high-rises in favour of more low-rise buildings, in fact far less building overall, ex-situ cement curing pretty much eliminates most of our best building techniques. Building techniques which would also contribute to lower emissions, by the way. Theres something to be said about smaller-scale use of this one, but its simply not a very flexible building material, and CLT or some other non-cementitious alternatives would likely be better for emissions as well as material properties on a smaller-scale anyway. Concerning the second one, it reminds me of why the focus on certain supplementary cementing materials as "sustainable" really bothers me. Some of the most prominent of these, like fly ash or slag, come from a similar source as the flue-gas-aggregate you mentioned here. That is, they all rely on the continued production of things like coal energy, steel, or flue gas to continue working as a solution. The way I see it, these "solutions" only exist for as long as we continue to predominantly rely on unsustainable industries elsewhere; pretty lacklustre. What's more, I'm sceptical of the water-resistance of this one because it's a non-hydrating cement, but the developers may have found a way around this. As a student/researcher in material engineering, I'm definitely going to continue searching for and attempting to develop long-term solutions for building materials. There are many promising paths in front of us in this regard, and the ones that you've chosen to present here are likely to be instrumental in their own right. But the more work I do in this field the clearer it becomes that the only acceptable path forward (in terms of sustainability) is a gigantic cultural and political shift. I know that its a meme to blame everything on capitalism, but that viewpoint is not without its merits. The capitalist may think that constructing their housing development by using the most modern green technologies will contribute to our global climate goals while still lining their pockets. The capitalist, here, IS WRONG. Many such "green" developments do not even begin to offset emissions that would be generated by a regular development until AFTER 2050 [1], because their efficiency is in their use-phase rather than in their production processes. The optimal solution, often, would be to never construct the development in the first place. Or, if more housing is required by the population, updating existing structures is more efficient (but less profitable, and more political) than constructing entirely new ones. The primary object of the invisible hand of capitalism will never be sustainability, at it will require incredible legislative leaps to make it appear as such to the capitalists. Here's the one source I cited. I can provide more if need be. It's good to keep in mind the time-scale on which alleged "sustainability" will occur: [1]: iopscience.iop.org/article/10.1088/1748-9326/7/3/034037

That the problem of climate change is a problem of technology. We have had the technology to stop climate change for over half a century. The capitalist class however makes very much money off of fossil fuels and the radical change necessary to stopping climate change is a threat to their profits. The only reason they support some efforts now is that they own/are invested in them and can now make money from them.

You should really do a video on farming insects for food. I have heard that eating insects is very common outside of the West. I have also heard that farming insects for food could potentially use less water and fewer resources, while producing fewer CO2 emissions, compared to most traditional livestock, such as beef.

Emissions from livestock account for about 14.5 percent of total greenhouse gas emissions, globally, and roughly two thirds of those emissions come from cattle - mostly from methane burped by cows, growing feed and clearing land for grazing and feed crops

I know you have a limited time to work on your videos and you want to be specific but I feel you really missed on talking about the crazy supply-chain of sand (which is in large part for concrete), which is depleting the stocks of sand in many ecosystems. Also I think it would have been great to talk about other alternatives that are not so closely trying to resemble the material and process of concrete (i.e. cross-laminated timber, fungi - These seem to me like much better alternatives from a degrowth and circular-bioeconomy perspective). Just my two cents

You forgot to mention another important side of the concrete problem: the transformation of green, carbon-absorbing, water retaining spaces into solid rock air-heating ones. No matter how small is the patch you are transforming: taking it from plants to concrete plumbets the biodiversity of the area and its capacity to absorb carbon. Now imagine what kilometers of concrete without green gallerys and green roofs is the doing to the planet. My friends: time to break some unnecessary cement and/or cover things with native plants.

How is solidia's foot print different from traditional concrete? That also absorbs co2 as it cures, that's how cement works: you remove the co2 from carbonates, obtaining calcium oxides (there's other components, but that's the basis of it) then when you mix it with water, the calcium oxides reabsorb co2, to harden back into carbonates. Also why didn't you mention wooden construction? With a well managed lumber source, there's arguably no building material more eco-friendly than plant material, and we already know how to do it, even big buildings too.

Zero emisjon? That is not possible. Then you and all living must die. Nature must die and the inner core of the earth must get cold. Most of so called emission is from nature, Then i include you. Your emisjon is 600 litres ore 1,5 kg of Co2 in 24 hours. That is not a bad thing. Co2 makes plants grow. The world is not in crisis. We live in a good time. It is the propaganda that is bad! The world is NOT heating up. Dr. Roy Spencer keeps an eye on temperatures where they should be measured: www.drroyspencer.com/latest-global-temperatures/. 1850 was the COLDEST in 10 000 years.Since then it has got just a little varmer. Last 20 years NO warming. Take a look at this film from ice core drilling at Greenland. Done by the university of Copenhagen: kzitem.info/news/bejne/0Y1nnIB9j4KXfJg Then lay back and relax!

@@arnehofoss9109 Common consensus amongst scientists is greater than the opinions of a few scientists. The overwhelming majority recognise that man made climate change is a big issue we're facing. You're right about nature fluctuating even without human involvement. But as far as I can remember from the SR15, I think about 0.6°C of the 0.7°C temperature increase was from human contributions, with only 0.1°C being from natural causes (these are rough numbers but the idea is that humans are the drivers behind most of the current warming). Make no mistake, we're experiencing an accelerated warming that would normally unfold much slower if we weren't pumping so much fossil fuels into the atmosphere. The only people who benefit from people like you and I not believing in the climate crisis are the guilty fossil fuel companies that have been polluting for decades. The hundreds of thousands of scientists doing studies and reporting what they find aren't generating insane profits from climate inaction/action

Using other materials such as wood needs to be explored as well. But honestly, at the enormous rates that we are buildung stuff, it would propably not be susuainable anymore either. We would need a lot of reforestation along the way. But it's interesting from a technology standpoint. I saw some documentary the other day, where a company was making building plates out of straw. They were pressed so they were not flammable and could be used for both structural support and heat isolation. But again, probably only really applicable to fancy free standing homes for the rich, that take up more unused land, as opposed to affordable houding in the cities...

Cement requires us to drain beaches and the sea floor of its sand. It is both terrible for the ecosystem and with rising sea levels, draining beaches is unsustainable. It's a recipe for flood. Cement doesn't last that long and it retains heat which with rising temperatures is making people who live in cement-built cities suffocate even more. European cities were built for more than a milenial with straw, wood, and soil. These building last for centuries with proper care, they maintain temperature at comfortable levels, and they are sustainable.

Would be cool if one of those alternatives proved sturdy enough to actually be used. Saw mentioned in another video that 'ash concrete' was less durable, but I'm not sure if that referred to the same thing mentioned in this video. Although I wonder what the carbon footprint for concrete buildings would be over time, with everything considered. Seeing they're durable, and allow for higher buildings (and thusly more dense population, which reduces traffic/need for roads and such). Like, how does that compare over 200 years to a building from less sturdy materials that needs to be rebuilt three times in that period, or a smaller building made from wood that leads to more space used per person? I'd guess it might still be not great, but maybe in perspective not necessarily much worse than the current alternatives (but no clue). But also, as other people have mentioned, there's so many empty buildings that are just being used for financial speculation (at least in several western countries I'm aware of). I suppose the RRRs of waste also apply to building, meaning Reduce comes first, then Repair.

Most of problems with this materials is not in resistance or safety as most people would think, but in escale and workforce. Little to no research has been done do develope ways to build with this materials in a scale that would chepen its manual work cost and make it competitive to concrete (the raw material is cheapper, the work it takes to build it's not). yet there're iniciatives, for me the most promissing it's the prefabrication of rammed earth walls, look it up The biggest hindrance it's the lack of regulation for this type of alternative material, which is itself a product of the concrete manufacturers lobbying against it
