to the day, i need the dots to lie 18 on d w. the to will speeches on 2 restraints or subbing. increasingly overwhelmed with visited a situation that needs locals running out of space and set up with the crowds. authorities up to strike a balance between the social impact of a terrorism on the revenues that helped to keep local economy so flight. oh, so on this edition of made, the huge cruise line is bringing thousands of terrace to already over crowded destinations. could ammonia be a clean alternative to the density engine, fuels, polluting the world's oceans and around the world? there was still too few females ceos. we may want

a minute. i drew beach grumbling, millions of people in one place, tourism is becoming a challenge. not far from barcelona beach promenade is being removed to make sure the tours keep coming. how does it all fit together? the answer is, it's complicated, because tourism is also complicated. on the one hand, through our crowds, 20000000 people visit barcelona grad from you. you get the draft and the market hall every year. they are often crowded. the city now wants to make improvements and is spending millions told us if we see is currently trying to manage tourism is positive for the city. yes. but you can reach a point where it no longer brings any added value to the next morning. i mean,

as to your kid who lives in the bus and oh, need the district right next to the port. she's fed up with tourism. her opinion on the town halls plans is very clear see about the continually in other words, barcelona will continue to be overcrowded. we need less tourism, but done well and purposefully not just investing millions in public money on something like turns out to be an effective political and i work in a lot of different people. the local resident is furious because the city is also spending millions to host the america's cup ceiling regatta. city hall believes this kind of event is right for barcelona, but it will bring even more tourist and not just towards the same, almost a few weeks ago. i got this letter from ankle and foot goes one of them saying that a lot of buyers will be coming to the city for the upcoming america. scott brothers case that i left you, that. that means that it's closely linked to the problem of speculation. and that's

plaguing this neighborhood. now this particular case, hopefully more able to be dive and one blog. i are combating the legal rental apartments in barcelona. they are 2 of $27.00 inspectors of their job is to find out whether there are short term tours, living in apartments without a license. nearly 10000 have been shut down in recent years. it's tough work. nobody opens the door at the 1st appointment police. those are the amount of payments on there are 5 apartments in this building that are under suspicion. you know, things become clear as a next door. they visit to me and i need some information. i just want to talk to you and so if there's anyone living here or are you cleaning after someone moved out? yes, that's well, i'm just here for the cleaning company. these apartments are for tourist, the wheels are finally starting to turn. it's a lengthy process. nevertheless,

i pick any in fact or can i have not been successful, especially with private landlords don't get away if you catch them. they actually reach donald sale, but it's different with the large owners of the 10152460 apartments across barcelona. so they don't really mind the 60000 bureau find target because they can quickly recoup the money from the other apartment has to be in the experts also consider limits on vacation rentals to be an effective approach. but at the same time, there was a clear rejection of other tourism alternatives which will mess content. all these, all of these things need to be abolished trailer but we also have to be careful to make sure that changing this doesn't lead to a lead as them get in thinking about the solution lies and holiday tours on the on which is actually a euphemism for tourism, for the welfare of you that kind of let them know families well if more rich people come, it doesn't mean that the tourism is get better and distributed and there are not enough rich people for every stable young man or either a totally legal spell that the, the main goal of the americas comp is to make barcelona attractive for wealthy

tourist like local resident esther, the geographer thinks the approach is wrong. it okay, is this, the type of event will lead to a disaster situation, which is part of the logic of creating events to attract wells, the taurus, as opposed to the fact that more rich people come, does not enrich the majority. but impoverish is us and creates more any quality you can imagine as the one that tourism is complicated. it could have been slowed down this summer in catalonia, by a lack of water, then it range just in time self. the barcelona, however, there was another example of how climate change can influence tourism over the long term of the same color says sand is being brought in for a lot of money to prepare the beach for the high season. you know what it says, book on say the auto fee and definitely remove the plaza here that took up 800 meters of space on this beach. i know that, but it stretched to where the man with the umbrella is holly. i didn't know. so

there was no center, doesn't mention it, but we removed the concrete about 2 months ago and we were able to create a new, the $1000.00 off and it on while i buy a lot more beach for summer tourist things to less concrete, that was one step because storms keep washing away, the beach and winter tours get less beach over the long term. the police low, the raw material for tours in the sand. this. so this is where the tourists come. this is where they rest. this is the main attraction. the main resource because they sat in a sand in this scenario like this one with climate change is a major challenge when i go stuff the only natural sand reserve we have is these do let me just say that i know it starts going on. this plan does the color filling model is considered an example of sustainability. the big difference to barcelona, however, is that large numbers of tourists only come here at the height of summer. the rest of the time, residents and nature can relax in barcelona the high season last all year round.

that's why i annoyed residents will also protest here against the re eviction and the america's cup. the. the overcrowding in coastal to res totes spots is not helped by ships offloading thousands of passengers at a time. ocean line is aren't the main industry, but one with a grains environmental impact to the flow team cities, least behind vast amounts of oil in our ocean endangering data could eco systems. so what explains behind on the massive dom onto the substrate 5 times bigger than the titanic? this is what the newest cruise ship looks like today, and it's booking out fast. the cruise ship industry is the fastest growing tourism sector, generating billions we visited cause

a man in mexico to see what all the fuss is about. we wanted, you know, what literally powers this multi $1000000000.00 industry the. this is the largest crew ship ever built. it's called icon of the seeds and measures 365 meters in length and can carry 10000 people out of time just over 3 quarters. those are the passengers kind of the seas as reflective up the rise of the booming cruise industry. the ship as just launched and is already open for reservations in 2025. but what's literally powering all of this? technically, in the case of icon of the seas, it's liquefied natural gas or l n. g. it seem as a more environmentally friendly fuel. more on that later we ask its owner royal caribbean for an interview and it sustainability strategy. the company did not respond to the request before our deadline, however,

but we did manage to get ahold of carnival cooperation, the biggest cruise company in the world. one of its slogans is sustainable from ship to shore. we recognize we have a like a need to maintain a pristine environment. so because that's what people come to see, they don't, they don't want to go see the things that have deteriorated. they want to see beautiful places and we try to take them there. that's bill burke, who's charged with making carnival a safer company for the environment. we traveled to the mexican island caused them male in the caribbean. it's part of one of the largest barrier reeves and the world cruise is a gives you actually the opportunity to visit many different islands. um, throughout your 7 days, you can hit so many different ports to ship, sir. amazing. and there's so many things to do on them resulted in big groups for one way. and you can spend 1002000 about both. you have everything. we did our own internet search and found out that you can actually get

a week long cruise to the caribbean for around $635.00 us dollars, plus taxes and port fees. and under the trend, the banner of sustainable tourism for climate consciousness. in fact, one study says that half of all americans believe cruise vacations are environmentally friendly, and vis. green badges, one proudly by the top 3 crews companies, carnival royal caribbean engine or region. norwegian is trying out biofuel mix planes and continues to use marine gas oil. in the longer term, it sees green method all as a promising source of power. carnival in royal caribbean, continue to use traditional views, and they both tells the current use of l. n. g is the best fuel available today for us to use from greenhouse gas perspective. and we pioneered that within the but what are the unseen environmental costs, according to $1.00 study, cruise and use more than double the carbon emissions of flying and staying in the 4

star hotel various cities including one of your busiest ports. barcelona have moved to restrict cruise ships because of their emissions. and norway has also announced that from 2026, only vessels with 0 emissions will be allowed to visit its fjords. this follows research that claims cruise line was in europe to meet as many times sick air pollutants as 1000000000 cars. after venice bands large cruise liners from anchoring units of storage center, it's reported that air pollutants fail by 80 percent. but hold on should to move to using liquefied natural gas, solve all of this, no carbon there, right? the easiest way to comply with the regulations on sulfur, nitrogen oxides and carbon dioxide intensity. all of the same time you see use liquefied natural gas because it contains almost no sulfur and

a good email, it's about 25 percent less carbon dioxide emissions spend conventional keels, brian comb, or is it not convinced about liquefied natural gas being used in the shipping sector, ellen g is made of methane, a gas that doesn't stay in the atmosphere as long as carbon dioxide, but it's 80 times more warming for our planet in the short term. and what's interesting about maritime companies using l n g, is this. many of them are choosing liquefied natural gas has their fuel. and the engines that cruise ships use tend to be those that you met the most about unburnt methane to the atmosphere. and we call that methane flip. this in for a camera shows a ship burning l. n g. the cloud to see show the methane that's escaping the methane slip, the more methane, the bigger the cloud crew shift industry events about $30000000.00 tons of greenhouse gases each year. and that's the same as $75.00 natural gas powered power

plants. what do you mean each year? the future? back to the question of what's powering this multi $1000000000.00 industry? well, it's clearly demand. just look at the size of icon of the seas. get it's run on ellen g of fossil fuel made up of methane, one of the drivers of global warming. but whatever fuels are being used, it's clear that they are in flux, as the industry grapples with a warming planet and tries to color in between the lines to the more formidable it's however, that was of our environment. we might already be over the edge of oceans and, and we're also polluted by the fleets of container ships. chris costing the clothes as an alternative to diesel ammonia could be a fuel of the future. it burns without producing carbon. on this cheapest the method old. it does require special engines, which in turn means adapting the ships. but ammonia could help to solve the

emissions problem of global shipping. this engine is a huge chatter for the shipping industry to clean up is that it runs on pneumonia and that means a 10 propel ship without anything. any common in theory is produced with renewable energy. ammonia submissions are close to 0, and the shipping industry really needs a silver bullet. it's not responsible for 3 percent of global emissions, but this might go to 10 percent because basically everyone is shipping goods around the world. but this engine has the potential to reduce those drastically. is this really the solution? but the few pieces of the puzzle are still missing a very big one. the ends up. well, that's one mess of ends. and as of now, ammonia engines for large container ships have yet to go into commercial production

. i'm really curious how this is actually going to save any fuel. as you can see, there are full cylinders. most people don't realize it's actually a cylinder because they are so we know each of them is 50 centimeters wide. this is the research facility of engine design, a. m a n. somebody know them for the trucks, but they also develop really big engines for really, really big ships. they were the only company that would let us boom and pneumonia engine, and development. it packs 6700 horsepower. and when it's finished, it's going to be as big as a family home. and this is the guy showing me around today. rus most home bed stroke. how is this ends in different from a normal data lives? first and foremost, we need to apply an additional set of components on the engine. and this is essentially the components you see right here. so 1st of all,

you have the yellow piping right here. these parts deliver the ammonia into the cylinder to combust, but they are not the only vital parts. so one of the most essential components on the engine is actually that ammonia shooting fixtures. ammonia doesn't have a very, very high clarissa grad you. so, so what is color vision value? it is essentially the energy it can contain within a certain volume, sofa, ammonia, v. we need to have very, very big fueled in texas compared to existing fuel oil engine in texas. and that, and that is of course, a design challenge. this also makes it difficult to store enough ammonia on ships, but let's stick with the engine 1st. once a monia enters the ceiling, the end is supposed to ignite. that's when it becomes really challenging, chemically speaking, ammonia is difficult to set the light as we can see here, inside the cylinder,

it only self ignites at around 650 degrees celsius ended. burns, about 12 times slow. well then, fossil marine fuels. that's because the chemical bonds with in the ammonia, a molecule our relatively strong. and that's how we simply need to inject a small amount of padded to initial and stabilize the conversion. you basically help the ammonia to ignite with what's called a pilot fuel. so fuel that ignites easy other pneumonia, diesel, for example. this combustion also produces malta and nitrogen. these don't burn and slow down the combustion, and a slow combustion can lead to byproduct, and they are a big issue. the names almost sound the same nitrogen oxides and nitrous oxide. nitrous oxide is 273 times more potent, executing the front of then c o 2 nitrogen oxides on the other side of poisonous a man has been testing the engine since july 2023 and with over $0.30 as they've

been measuring all kinds of emissions coming out of it, the good news. they are between 85 and 90 percent lower than those of a heavy fuel. and the major challenge still is getting rid of both nitrous oxide and nitrogen oxides emissions. so one big concern, also nitrous oxide emissions with these engines. how do you get rid of them? well, we have a lot of paternity is when it comes to control, need to come rushing, pressure the combustion timings, and that by also the temperatures. and those handles alone allow us to add why deformation of nitrous oxide. as a rule of thumb, higher combustion temperatures lead to less nitrous oxide emissions. but how much oxygen you put it also plays a role tweaking these bear me just 10, reduce the emissions. so nitrous oxide emissions can be dealt with according to m a n, but they are still the pores list nitrogen oxides emissions and those require

a catalytic reduction react uh similar to a car. the engines exhaust travels through honeycomb like filters in cars. ammonia needs to be added as it's essential for the process to work. but in an ammonia engine, you already have some ammonia left over in the exhaust gas, nitrogen oxides and ammonia, and to travel through the layers and outcomes. nitrogen will to vapor and a small amount of nitrogen oxides compliant with emission regulations. this works rates when the engine is running at the power, but when it's not the temperature in the ends and decreases, this can lead to more nitrogen oxides emissions, which are re what need to deal with. but you don't really release what your car in findings on the level of interest. this is an ongoing on the process. and once we scale it up, once we get clarity and transparency of, of course, those details will be communicated to the market. being a critical journal,

as though like we are not marketing people who are the why would you say that the police of please. okay. these engines are fine now? well it, it's, it's, it's a fast point. so when it comes to ammonia engines in the future, of course, we will have to provide clarity and transparency in the industry that by also committing to to said, guaranteed levels of greenhouse gas emissions. i mean, if we replace c o 2 emissions with certain levels of into emissions, we will not do anything good for the environment. more importantly, we will not have a commercial and relevant product. m a n says that contract plan to deliver the 1st commercial design of the engine in 2024. the 1st ship, fitted with one is due to set sail in 2026. by pull that to happen, even more things need to fall into place. for example, the ships need to be redesigned because ammonia has

a lower energy density and your regular marine diesel. so the tank is needs to be bigger to pack the same amounts of energy. that's an additional safety measure, because ammonia is extremely toxic. if you're exposed to it for too long, you can die. so you need extra service tang systems to catch and recirculate the ammonia plus good ventilation. all of these costs money. and for companies like m a and energy solutions, a return on investment isn't 100 percent clear yet. and then continue to dominate corporate baldwin's the world a that for all the talk about, the changing women are still more of an exception. on the executive front. we take you to manila to meet one of those exceptions. ryan of rito has truly taken off not just as the ceo, but also the founder of the company. the i

started the airline during the pin that made. and that time i didn't really know much about the airline industry yet. my name is ryan, a breeder. i am the ceo of sunlight air. i am 28 years old and i'm from the philippines in the airline industry. there are just so many government regulate the manual as policies that you have to have approved. so in the beginning, you really need to go and meet these local government units. the i've had people in my team, they don't want me to go because people might not thinking seriously or that they might disrespect me because i'm a woman. that is something

that you could experience as a young woman in an industry full of men. but i of course, as a woman in the 20th century with pride, i say, no, i will go a step into the room and i tell myself it's okay, you can do it. i and i start to prove everybody wrong. i meet these people and get our licenses from these meetings. eventually, of course when i say of charge of operations of sunlight, hotels, and resorts from my dad. there was no sun life area as well . that time there were really very little airlines that were flying. so that was

the main reason why we started the airline business from light air. it's really brought funding the business this by the putting that meg i've always drawn a sunlight air to be at least one of the stuff, 3 or 4 domestic airlines in the philippines. so i want to grow more out domestically and then hopefully grow some regional slides. we're in the industry where most of our staff are me. so it's important for us that we are welcoming all females by the female and mechanics were welcoming off female engineers. the we need to lead

children of the generations of the know that if they want to be in the airline or aviation industry, but they are more than welcome. so basically you see, oh, i call for everything that happens in this business. ready i would want to take a step back a little bit. i have a team of a 120 now, and i do want to delegate to my team as much as possible. but sometimes yeah, i cannot help much know every detail because of course, like i said, this starts off this baby from scratch. i cannot help to know every detail, but yes, i am hoping that i get to let go some details the not see it for another edition of may be able to use business magazine this time
