The International Transport Forum (ITF) releases a biennial report on how we can reduce the carbon emissions from transport - planes, trains, automobiles, and more. This video is a summary of the recent 2023 ITF report, breaking their "high ambition" framework down into fifteen steps. Are these steps the optimal pathway to decarbonising transport? Quite possibly not. Is there lots of complexity in the report that I don't have the time to discuss in the video? Definitely. Are sustainable aviation fuels realistic? Doubtful.
But this video is an overview of one - at least quasi- - realistic pathway to slashing transport emissions. It contains several points that I am doubtful of. But I hope this is a useful starting point, based on a respected think tank and established literature. If you would like to learn more, please check out the documents below:

Video title: How to decarbonise transport
This video is about how to decarbonise transport - how we can move around without emitting (as much) carbon dioxide. This video essay is based on the International Transport Forum (ITF) and their reports. The 2023 ITF report has lots of detail on how the transport can reduce its carbon emissions, that I summarise in how to decarbonise transport in 15 steps. If you like videos from Wendover Productions, Kurzgesagt - In a Nutshell, Climate Town, Not Just Bikes, or Real Life Lore, you'll enjoy this video essay about how to reduce carbon emissions from transport.

I'm surprised forcing manufacturers to build lighter cars is rarely mentioned as a stopgap, especially when it's affecting many other issues. The weight, size and power creep has been immense over the past few decades. Having people alone in their 2 tons EV tanks isn't gonna cut it, especially if only the upper middle class can afford it without getting into debt.

It was tried. It failed. The CAFE standards of the 90's were on their way to being successful when Edsel Ford Jr. led the subversive charge of corporate communism in the USA and linked arms with other SUV makers globally to escape the domestic vehicle rules, accompanied by an open campaign of product placement targeted at young men in action movies (what, you think Fast & Furious, Stallone and Schwarzenegger got financed for their art?) and an under-the-table campaign aimed at mothers to scare them out of the safer smaller vehicles into big SUVs and vans with far worse safety outcomes. The only way to force manufacturers to go less fossil-emissions intensive is to make it clear to them that fossil is going away. Curtail fossil extraction 2% of today's level per month down to zero by 2030. Do it openly. Say you're doing it often. Get the message through that anyone buying a gas guzzler is going to be left without fuel.

@Anankin12 10 месяцев назад

Funny thing is that air pollution (NOT related to greenhouse gases) will not be solved by electric cars, unless a breakthrough in solving their weight happens. Brakes and other mechanical components common to all kinds of car will release pollutants that are harmful to us, and the removal of the engine generated ones is almost exactly compensated by the increase of emissions of every other component due to the extra weight. An electric car that is driven regularly is ALWAYS better than a ice one, tho, on greenhouse emissions, even if the energy used to run it comes from the worst possible current source of energy -coal- because of how inefficient the entire infrastructure to make, distribute, deliver is and the thermodynamical limitations of ICE engines (operating temperature and pressure put a hard cap to engine efficiency at about 45% if I'm not mistaken). So, tafic elimination is the best solution for cities (as stated in the video), but it would also be the best solution if we weren't goin through a climate crisis of our own making.

HSR in Australia is essentially a policy just brought up by governments during elections to entice voters and then as a money making scheme for the consultancies that are inevitably requested to write a report on it. We should really concentrate on improve state rail systems and connecting major cities in the state with faster rail before upgrading to HSR between the capital cities.

@tim290280 11 месяцев назад

HSR isn't financially viable, and logistically it is a mess since all the rail networks were sold off. Rail gauges don't match between states and so much of the former network is in disrepair. But that's the excuses, realistically it can be done pretty quickly and would radically change things.

@hedgehog3180 11 месяцев назад

@@tim290280 HSR is usually an enormous money maker so I don't know what you're talking about. They're so profitable that often the government doesn't even have to provide much funding because private investors are willing to step in, for example the first leg of the TGV network was paid for entirely through private investment. This is also why you're seeing a ton of privately run HSR companies springing up in Europe. In the hand of a national operator HSR lines can help cover the cost of less profitable regional routes, which are needed to seriously cut down on road traffic.

Very interesting video. We're definitely caught up in a situation where transport advanced so quickly and we've completely normalised it to such a point that we can't look at it from an outside perspective. In such a short amount of time, we've completely built our systems around strange metal contraptions dependent on long dead crushed microorganisms, or rare earth metals extracted from across the world, and while it's been good for us, now so many see these metal contraptions as the only way to go. Look at the outrage and panic over the concept of 15 minute cities and building our societies around humans instead. There's no real recognition that masses of people stuck in traffic constantly because many necessary services are further away isn't really normal but it's perceived as an attack on the ordinary everyday people. That said, I don't blame them for being sceptical and distrusting with how very little has been done at the political level to try and cut down and restrict the use of private jets used by a minority of the population. Flight is also very interesting when you truly take a few steps back and admire the sheer spectacle of it For millenia, man looked up at the birds in the sky and dreamed of the possibilities of what it would be like to fly with such freedom and peace. Now here we are just over a century since flight with planes started off and so many take it as an absolute birthright and completely normalise it, bitching and moaning all the way about the sheer inconveniences expected getting to the airport through security, and boarding a flight with so many others, likely to sleep the whole journey and not truly grasping the absurdity of these flying vehicles that will let us travel distances our ancestors could only dream about in such a short amount of time

Great video, 2 small points that I feel went understated that could use more emphasis. - using trains more for transport of goods in between cities; even diesel trains will often have less emissions than electric trucks due to emissions repairing road damage, and there is a lot to be gained in this area instead of focusing on stuff that is already hard to do or would be more difficult (like increasing energy production while becoming greener to power eTrucks) - there is a lot to be gained in investing in lower income countries, as investment dollars go a lot further and there is often huge areas to improve. I live in Brazil, and while we are doing remarkably well in terms of having renewable sources of energy, we have virtually nonexistent rail infrastructure both in cities and for long distance travel, and doing so would help the world a lot more than making traveling from Rotterdam to Amsterdam even better

Intercity frieght is basically just use more tried and true trains.

(One basic example is to not tax rail corridors by the number of "lane miles" such that a double tracked corridor is taxed at double its single track equivalent. It doesn't occur everywhere but its an example of a bad policy/regulation hampering proper infrastructure.)

Great video of showing the current options. It still leaves out our reorientation to traveling. You mentioned relying more on video calls to connect ourselves digitally over long distance. In my opinion traveling via shipping can be another solution. It currently takes around 7-9 days for a freighter to cross the Atlantic ocean from Europe to North America. A week of travel might seem long but if these travels are organized as a sort of ‘cruise light’ with work spaces and cheap accommodation it while also carrying regular freight along the way it might be the most carbon neutral mechanized travel possible. Currently traveling by freight ship is more expensive then traveling by plane and freight travel is still under the covid measures a lot of the time making it almost impossible to book such a trip. Besides this dedicated passanger travel across an ocean which are faster then freight is possible and can cut down travel by 4-5 days. Again great video and would love you to make a video about slow cross ocean travel!!!

Good to see you back Simon. If you take into account full life cycle carbon costs then wind assist (WA) is hands down the most carbon cost effective form of alternative power available to shipping because the power is delivered free at the point of use. The cost is vested in the capture devices, the sails and as mass production kicks in the cost of WA will be falling by around 2/3rds while the cost of hydrocarbon and other combustibles will be rising above inflation. The International Wind Ship Association (IWSA) has calculated that if the shipping industry were to adopt WA across the board now the savings would fund all the other emissions reductions costs the industry will face going forward. Just saying:).

@thamiordragonheart8682 11 месяцев назад

wind assist is pretty amazing. I think a lot of bulkers are already getting fletner rotors as retrofits because it's so easy and effective. What would be really exciting to me is new build ships designed to carry kite sails from the start, preferably a pair with one forward and one aft so that they can be balanced to still assist when you aren't doing downwind, though maybe trade wind routes will come back for less time-sensitive cargo.

@Croz89 10 месяцев назад

@@thamiordragonheart8682 Wind assist works well with bulkers because they can afford to vary journey times much more, you have a stockpile at either end so you can sail slower or faster, or even delay departure altogether, to take the most advantage of wind conditions. Container ships on the other hand need to keep to a stricter timetable, even if the journey is slower to save fuel they need to have reliable and consistent journey times so the next link in the transport chain is ready when they arrive (JIT manufacturing). You could still have them of course, but whether you'd use them enough to justify the cost and maintenance is another question.

@thamiordragonheart8682 10 месяцев назад

@@Croz89 Container ships also have geometric problems with mounting wind assist because the container stacks are so tall. I think kite sails could work for container ships that run between East Asia and the US since the north pacific trade winds are reliable and not too far out of the way in either direction on that route. I agree that wind assist for container ships would seem to be a serious challenge on other routes though. The good news is that I think bulkers cover a lot more ton-miles since bulk goods are just so much bigger, so even if wind assist only works for bulkers that's still pretty good.

@Croz89 10 месяцев назад

@@thamiordragonheart8682 Probably better to focus on slow steaming. Container vessels are usually not time sensitive in terms of speed per se (if you want anything quickly it will go by air), only in terms of consistency. If a container takes 4 weeks instead of 2 weeks, a manufacturer can send out a container twice as frequently and the customer still gets the widgets at the same rate. It's a little more expensive, but if the container cost was lower because of lower fuel consumption, much of that could be compensated for. If however, the container may take 2 weeks *or* 4 weeks depending on wind conditions, it not as easy for the manufacturer to adjust, they might need to start stockpiling widgets which will likely cost more than an extra container.

@thamiordragonheart8682 10 месяцев назад

@@Croz89 I agree with your logistical argument but do feel compelled to point out that wind assist means that the wind isn't strictly necessary for propuslion. Storm survival alone probably requires that those ships be able to make nearly 20 kts cruising speed in calm weather on the main engine so that they have enough power to control the ship and stay off a lee shore in a hurricane. I think the idea of most wind assist technologies is that you turn down the main engine when there's wind you can use and turn it back up when there isn't so that you can take advantage of the wind without changing your cruising speed or schedule. It's also important to do that because bulbous bows only work at one specific speed. that's also why I specifically mentioned going between east asia and north America as the only viable route for container ship wind assist because it's the only route where you can get reliable enough strong tailwind in both directions for it to be worth the investment in the short term (a couple of years)

4:00 there actually is a point in electric vehicles WITHOUT decarbonizing the electric grid. Power plants are so efficient because they can harness heat byproduct from energy production and turn it into stream energy; something no internal combustion engine in a car can do. Hence, per gallon of petrol or ton of coal, you get way more energy (and thus way less emissions) if it goes into a power plant and then into a car, than straight into a car.

Pretty much any engine/generator gets more efficient as it gets bigger even before taking things like that into account too. My understanding is that even if the powerplant was don't very little other than just running a Very Big generator (no idea if that's actually a practical thing, mind you, and obviously there are Better ways of doing things), it would Still be better, emissions wise, than having an engine in each invidual vehicle (better for maintenance costs too!)

@@laurencefraseras an electrical engineer you are kinda right, before i explain how things work i will list the general efficiencies. ICE ≈ 20%, max is about 30% for diesel EV ≈ 75% Classic thermodynamic power cycle ≈35% Transmission lines ≈ 95% (means the grid is overall 33% efficient) Combined Cycle nat gas ≈ 55% efficient. Co Gen: 80% efficient (its cheating as it isn't purely electricity produced) ICEs work by exploding a small quantity of fuel vapors to shove a piston down and then convert the linear motion into rotational, it then goes through a bunch of gears before reaching the tires, just inherently inefficient. (I hope everyone here already knows how a car works) EVs instead use batteries and electric motors connected directly to the wheels, and can syphon power back out of motors to brake since motors and generators a physically the same thing. Electricity is inherently far more efficient at energy transfer than mechanical systems, hence the massive gap between the 2 cars as end use machines. As far as generation goes, most generators are fundamentally just spinning a magnet inside a coil of wire. Large generators use an electromagnet but small ones just use a permanent magnet for simplicity, all the different power plants are just looking for ways to spin the shaft of the generator. You could use and ICE but as mentioned they suck. The classic power plant uses the thermodynamic power cycle which extracts "work" out of energy flowing from a hot sink to a cold sink. Energy has to be "rejected" to the cold sink for the cycle to produce work. The basic installation is you boil a working fluid (water), run the steam through a turbine (extract the work), condense the steam in a condenser (reject waste heat), and then pump the 95°C water back to the boiler. (You have to put work in too) The ideal efficiency is based on the temperature difference, ideally you would be super hot and use absolute 0 for a cold sink, real world isn't ideal so the realistic temps limit this to under 40% ideal) Gas combined cycle starts with a 30% gas turbine (burn gas and use the exhaust to power the turbine, basically a jet engine) and then dump the waste heat into a classic power cycle and they get to double dip the energy from the fuel for an overall efficiency of 55%. Co-gen is a power plant that sells its waste heat via district heating instead of dumping it into a body of water or the sky. This is how they get 80% efficiency, its still only 30-50% electricity efficiency but they sell the heat as well. Otherwise the actual generator is the same between these power plants. And as you get bigger it becomes possible to chase after higher efficiencies, partially because the actual magnitude of the losses increases enough to justify the effort of recapturing or mitigating them. (Assuming they aren't mandatory physics losses like with the power cycle or aerodynamic drag on a car)

I work in cold chain logistics and am considering a move to transport engineering and your mention of sharing delivery vehicles excited me. I started as a delivery driver and used to find that there’d be days where I’d all but follow around the same couple of trucks from rival companies to the same destinations, often getting in each others way and having to circle the block due to limited loading zone capacity. Ever since then I’ve always been brainstorming ideas for how to make this more efficient. I’ve thought of things like an app that all delivery drivers could run that would tell them if any nearby drivers had efficient freight swaps on offer (Ie, both drivers will be at a shared location at about 11am, and by moving only a couple of boxes between the two trucks they can both make 1 less stop. Let Truck 1 take anything Truck 2 has for Destination A, and let Truck 2 take anything Truck 1 has for Destionation B, and they both get to make less stops, and won’t be competing for parking space further down the road. Also that’s just a demonstration, the same process could result in the reduction of stops a lot more than just 1) Obviously, rather than rival courier companies fighting over the same real estate the best solution in this case would probably be socialise it all, put gigantic distribution centres for all freight types at the compass points of your city and centrally plan the delivery routes for maximum efficiency and utilisation, but if we must work within capitalism then I’m sure there’s still something that can be done in that direction.

I think the current housing crises actually play into this quite a bit too. As someone who’s been trying to find a new rental for quite a while I often think about this. Obviously what I’m about to propose could probably be done far better with central planning and socialised systems but even leaning away from setting off any authoritarian alarm bells, what if we just placed some gentle pressures on the current rental market that incentivised property managers to select tenants who worked close to the potential house? They’d still be able to pick and choose on all their regular things “do they play the drums, do they like playing with matches, etc” but once you’re down to 3 more or less equal great tenants, imagine if all 3 had an ‘ease of commute’ score. I bet there’s so many cases of two similar applicants on similar incomes who are both applying to any place in a 10km radius around the city centre, and then through the luck of the draw, applicant A who works on the southern end of the city centre, gets a house 10km north of the city, where they’d have to change trains to get to work by train, and applicant B who works on the northern end of the city centre gets a house 10km south of the city and they also need to change trains to get to work. Therefore, these two people who could have had easy-breezy 15 minute train commutes both end up opting to drive. It would probably need to be an opt in system, and it’s probably only applicable to people who know their employment is reasonably stable, but I’m sure there’d be chances to exploit this to cut emissions. Maybe even if you taxed rental agencies based on the commutes of their tenants? (Even this could see a few investors sell their properties and help with the supply issue a little bit) Anyway, I know there’s a million issues with this idea, but someone gotta be thinking of something right?

@jasonreed7522 11 месяцев назад

That's a very hard topic to do true justice too because you would need to track down so many different externalities associated with building, operating, and eventually disposing of such a vehicle. By CO2 emissions the EV will eventually always win, even on a 100% coal grid. (EVs are 75% efficient from the outlet/charger, ICE's are 20% from the pump, that a huge advantage) But CO2 isn't the only pollution to consider, theres also chemical like SOx, NOx, and whatever comes out of a cobalt mine, and particulate in the form of soot and brake dust. But you also get to some unexpected externalities like increased road wear from the heavier EVs or the fact an EV fire takes more water than a typical firetruck holds while an ICE does not. And at the end of all the data collecting and normalizing, you will have to make a judgement on what types of pollution/externalities are worse than others. This isn't impossible, but it is hard to do the topic true justice and provide an definitive conclusion. (Maybe it ends up close and you decide that african children mining cobalt is worse than american children getting asthma from the NOx of their parents ICE cars, just for an illustrative example of why comparing across pollution types is hard)

A thing with biking that is super obvious but still requires some healthy thinking is the sphere of influence that a business or other sort of destination has. I would wager that people generally have about a 10 minute limit on how long they would like to walk to somewhere before they take the car. This might be a small corner store, or a bus stop, but that's the same in the analogy. If a person walks at 5 km/h then that means there has to be a bus stop every 1.6 km. However, if you bike that speed goes up to 15 km/h minimum (or 20 on an electric bike) then you only need a bus stop every 5 km!! This also helps small businesses stay alive, because people are more inclined to "just go out for a couple minutes" to get to it and buy a small thing, rather than make it a whole ordeal to get in the car and drive the whole way there. A small corner shop won't function with only car traffic, because no one is going to get in their car and drive for 7 minutes, just to get a single chocolate bar because they wanted chocolate, but they would bike that way.

Maybe i have missed it, but when talking about improving fuel efficiency, you didn't mention the jevons paradox, which I think should definitely be talked about in this context. The problem is that if planes or ships become more efficient, they will (obviously) ue less fuel, making transport and travel cheaper, which increases demand, and thus also increases total fuel use. I am not sure about how much empiric evidence there is for the paradox, but as far as I know it has been observed after James Watt massively improved the steam engine (increasing the demand for coal), and when planes have become much more fuel efficient in the middle of the 20th century. So we should always have it in mind when considering improving fuel efficiency as a potential solution for reducing our emissions.

I guess one step in reducing long distance freight transport is to incentivize regional production of goods wherever possible. And also probably to get away from consumerism more, for example by using more durable products, repairing things when possible, buying second-hand, sharing things among people and avoiding buying products that you don't necessarily need when possible. One less obvious advantage of that would also be that there would be less garbage. The disposal of garbage also creates travel emissions, often even internationally, when first world countries send their trash to developing countries where it creates health hazards for many people living there.

I find it problematic that more people living in city's at any one time is to be taken for granted... You can't really involve people in the ecological process whilst forcing them to live separately from it. While lower per capita resource requirements are often touted for urban living, I feel there are probably diminishing returns after getting to the size of a well designed and clustered town/village, be that permanently settled or temporarily/modular constructed in flexible ways. The latter provides the most flexibility to involve a section of the population in ecologically pro active work and activities. Bio dynamic agriculture, best practice horticultural and conversational methods and initiatives ect. I feel that actually you can facilitate a much better quality of life for relatively less than ever more sprawling and dense urban subsistence. Seems like the idea is only less resource intensive than suburban sprawl or more fully detached rural homes, partially communal living is far better though. What advantages does an urban district have over a well sized and clustered village/community layout in a semi rural setting? If accommodation is clustered to improve thermal efficiency and if the village size is designed and scaled to a decent point where all required services can be delivered to a good number of people efficiently? How else can you account for the potential ecological and environmental benefits of rural populations or semi nomadic community ect?

But neither of those options are beneficial for social fabric.

@leifcian4288 11 месяцев назад

@@butterflysleg9649 So the first assumption is that you need 1000s of people in an office building for collaboration purposes, which depends on work options within a city. More job option that require a long commute is not what's necessary for the environment, while yes working office type jobs only remotely causes issues and really it's better for people to attend in person and be present for one another, at least some days of the week. Not everyone needs to do office work though, in fact considerably larger proportion of the population needs access to land in order to do the sort of ecologically pro active horticultural/conservation and better practice bio dynamic agricultural work. Of course a "cluster" of dwellings or accommodations is significantly more efficient than detached suburban spall or individual dwellings dotted about. However what are the significant benefits beyond a well designed cluster of dwellings and services larger than a village/town kind of size? If you look at historical towns and villages, the dwellings tend to share walls or are multi story and not detached, lots of example villages are nice and dense for their size. They had to be as historically energy was not nearly so abundant and cheep. So you can have the exact same density of a city district/block without needing to be as large as a city, in fact you can design *more* dense than a larger city because that won't impact on people's quality of life as much when they have nearby access to large open space landscapes and nature ect. So in addition to better design of towns and villages I would also advise modular accommodation that can be assembled temporarily and disassembled for logistic transportation, temporary villages that relocate from one work project to another. This would unlock a lot of environmentally pro active work options on landscapes, both for seasonal work and one off projects.

I believe there was an experiment or theory running for larger cargo ships to use small, modular nuclear reactors for power. This was a small hype for a bit and I never heared of it again. Could this be an option to decarbonize cargi ships?

@jasonreed7522 11 месяцев назад

50 cargo ships sink a year, sometimes in harbors. The problem of nuclear is that its inherent risk has such massive consequences for failure compared to other technologies. Sure spilling thousands of gallons of oil into the harbor is bad, sure detonating a full tanker of LPG is basically a nuke, but atleast their consequences wont be a salting of the land rendering in uninhabitable for thousands of years. Nuclear cargo ships isn't an option because cargo ships aren't reliable enough to not have too many near misses or Chernobyls a year for comfort. (Let alone to convince anyone to insure your ship) Ultimately cargo ships will have to use some type of carbon neutral fuel, possibly a derivative of biogas (methane) or ethanol. Which would also have the benefit of being low sulphur. Ships are incredibly energy efficient already and can always slow down for even greater savings.

@@jasonreed7522 You're not entirely wrong that nuclear energy has the potential to have higher risk than carbon-burning energy, but saying "detonating" about a nuclear reactor is telling me you're not entirely informed about how reactors work.

What if we take the planes of the transport chategory?

@kevincronk7981 11 месяцев назад

Most countries already have bans or restrictions on short distance flights unless it's to some place you can't reach otherwise or it's a connecting flight. Banning short haul flights really just means banning short connecting flights, which are often necesary to fly from smaller airports to just about anywhere, if that airport connects to a nearby large airport which serves as a hub for flights. If you really want to ban these flights in particular, you either have to simply screw people over without giving them a good alternative, or build high speed rail between nearby airports which serms kinda silly if you're trying to move away from flights altogether

@laurencefraser 11 месяцев назад

Pretty sure that the idea with rail is that in most cases those smaller airports are replaced with railway stations. High speed isn't the only type of passenger rail, after all.

I think something that usualy is forgoten or brushed over is the manufacturing emissions. Especially for eletric cars atm as mining lithium and other components are very destructive to the environment. This also goes for at the end of the life cycle, how do you get these matetials back? Or is it trash? Energy storage is always the biggest issue imo and considering fossil fues are very energy dense its hard to beat(although engines aren't that efficient).

Hasn't France already banned short-haul domestic flights (this year, IIRC)?

Yes

Wait why is 'aviation and shipping' a different entry on that first graph than 'transport'?

Cities skylines, nice! And all the urban changes are literally what urbanist youtubers consistently mention about. Living in Jakarta, a city with bad planning and urban sprawl, having cities you describe is so desirable. Imagine not needing a car to go everywhere, less traffic, better air... I don't agree with you that trains don't fit Indonesia. Most of the population lives in Java, a small dense and decently flat island. Implementing good high speed rail will significantly reduce plane usage. However, interisland travel does require planes. The only connection trains can do in my understanding is Java Sumatra and Bali. Papua, Kalimantan, Sulawesi and the Nusa Tenggara Islands need planes. But by that point, carbon emissions from Indonesia should be really low and can be offset by algae, trees and carbon capture (I think?) Maybe planes can utilize hydrogen technology? or ion technology. Either way significant advances in battery technology or hydrogen technology are required.

A quick Comment on shipping: there are designs that go to the old idea of sailing and modify it. These designs look strange (large rotating Zylinders) but the promise a large reduction in fuel consumption, since most of the energy comes from the wind. This would need to be incentivised however, since the owner and Operator of a ship are often different and the main profiter would be the operator, not the owner.

Similarly, I recall something using large kite sales that was looking pretty promising some years back.

It might work for bulk carriers who aren't concerned about keeping to a timetable. For container ships the economics might not work out if they don't end up using them much because they will arrive at their destination too early or too late.

@PunkHerr 11 месяцев назад

I hope there will be a follow up on "the problem with decarbonisation with intensifying dependency on lithium." Some solutions you mentioned are good on every environmental scale (like public transport, biking or denser cities) but other cause on other fields problems (to name another example water consumption/pollution). Switching to electric cars is unluckily a moving of problems. Cars are just ineffecient (even more compared to airships!).

@hedgehog3180 11 месяцев назад

Shipping is at least one of the sectors that is most friendly to carbon reduction schemes. This is because fuel is the single biggest expense for them and they've already gone to great lengths to increase fuel efficiency such as adopting slow steaming, so the shipping industry is very happy to adopt anything that can increase fuel efficiency. That might be why we've seen even some pretty radical concepts get full scale tests. Compared to many other sectors it probably won't be hard to get the shipping sector to adopt many of these measures. Fuel is also a pretty big expense for airlines but they have the competing interest of not wanting to lose market share to rail travel.

Two things 1, I find some times that there’s more pressure to decarbonize public transport them. There is decarbonize cars which can be really annoying and add to the stigma against public transportation. 2, it’s not all that annoying because there’s maybe a tiny bit of truth to having the public transport sector decrease their carbon emissions.

@jasonreed7522 11 месяцев назад

Its also easier to decarbonize public transportation. Trains are often considered the "be all, end all" of public transport and they can be easily modified to draw power directly from the grid (either 3rd rail or overhead catenary). Electric trains are also typically just strictly better than diesel, they have more power, both already use electric motors, and they can go faster & regeneratively brake. By contrast electric cars are not objectively better than ICE cars, they may not have the emissions but they charge slower, need heavy batteries, burn hotter and longer, and you still have all the other problems of car dependency. (You can also fix their emissions by getting mode share change towards an already decarbonized public transit system and get benefits beyond just reducing CO2 emissions.)
