Latest / How To Protect The Ocean / Why Cargo Ships Are Bringing Back Sails to Cut Emissions
Transcript
- 0:00At the start of 2026, there were between 50,000 and 116,000 shipping vessels
- 0:07trading some sort of cargo on the ocean.
- 0:10And that is an incredible number.
- 0:12And if you really think of what we're looking at from
- 0:16shipping and climate change.
- 0:18Shipping is responsible for 2.1% of the global CO2 emissions,
- 0:24according to the International Maritime Organization, the IMO.
- 0:27And we're gonna be talking about how some of those shipping companies are
- 0:30trying to not only save costs on fuel, but also help the environment
- 0:35by reducing their CO2 emissions.
- 0:38So we're gonna talk about that on today's episode of the How to Protect
- 0:40the Ocean podcast, because this is where you find all of your latest
- 0:43ocean news, your sustainability news, here Monday to Friday.

- 0:54Now, this week, we have an interview on Friday.
- 0:57We're gonna be talking to Alexandre Mendron.
- 0:59He owns a boating company where he sells boats.
- 1:03And part of that, what he's really proud of, is his electric vehicle
- 1:06boats, so his electric motors that he sells on a regular basis now and
- 1:10he's working with a bunch of makers.
- 1:12He creates the motors in a manufacturing plant in Montreal
- 1:15and then ships them out worldwide.
- 1:17And it's really interesting to see how he got into it and
- 1:20what he likes so much about it.
- 1:22So that's on Friday if you wanna hear that interview.

- 1:37That's speakupforblue.com/patreon.
- 1:41Okay.
- 1:41Let's get into the show, because this is something that's really
- 1:43interesting, 'cause global shipping moves roughly between 80
- 1:46and 90% of the world trade volume.
- 1:49Like, think about that for a second.
- 1:50Like, that is a pretty big amount in terms of what we're looking at shipping.
- 1:55Everything we get, like all the stuff that we get from Amazon, all the stuff that we
- 1:58get that's shipped anywhere or even that's created and made overseas, especially if
- 2:03you're in North America or even if you're in Europe, gets shipped to those places.
- 2:07That's incredibly, incredibly large amount of percentages, right?
- 2:11And then the industry, like I mentioned before, is responsible
- 2:13for close to 2.1% of the global CO2 emissions, according to the IMO, the
- 2:17International Marine Organization.
- 2:20And companies are now retrofitting massive cargo vessels with rigid
- 2:24sails and wind structures instead of relying only on new fuels.
- 2:28So that's a really big deal here, where you have a shipping industry that is
- 2:33massively important to the world in terms of how much it ships of the cargo
- 2:37and how much it's involved in trade.
- 2:39We also know that it presents a large CO2 emissions and it has a
- 2:43problem, and it needs to fix that.
- 2:45And there are a lot of organizations, a lot of of governments who
- 2:47are putting regulations on CO2.
- 2:51So whether they're gonna be putting it on the flag that these ships are sailing
- 2:55with, whether it be Canadian or anywhere in the European Union or anywhere in
- 2:59Asia, they will have to do something at some point, and it might be now.
- 3:03Cargill's Pyxis Ocean is a company, was fitted with two WingWing sails,
- 3:08each standing 37.5 meters tall.
- 3:11And as of mid-2026, more than 100 large cargo ships, over 400
- 3:15gross tons, have wind propulsion systems installed worldwide.
- 3:19Now, the International Maritime Organization set a target, just as I said,
- 3:22of at least 40% emissions reduction from shipping by 2030, with a net zero by 2050.
- 3:29So that's a lot between like, you know, going from 40% all the
- 3:31way to 100% by 2050 in 20 years.
- 3:34So a lot of the work has to, and infrastructure has to be put up now.
- 3:37So fuel costs and tightening emissions regulations are pushing ship owners
- 3:41towards proven low-risk technology rather than waiting on new fuels
- 3:46like ammonia or methanol, right?
- 3:48And wind is free once the hardware is installed.
- 3:51So unlike alternative fuels which require new infrastructure, so instead
- 3:54of building all the infrastructure that's needed for like ammonia fuels
- 3:57or methanol-based fuels, which are still will cause pollution, you
- 4:01can go back to the old school way of getting across the ocean and use sails,
- 4:05because wind is free when it's there.
- 4:08And now things will be changing with wind, and the trade winds might
- 4:10be changing due to climate change.
- 4:12But we will see vessels and we're starting to see vessels who are actually
- 4:16trying to use wind propulsion to help offset some of the costs of fuel.
- 4:21Fuel efficiency is one of the most important things 'cause it's so expensive.
- 4:24And now with everything happening in Iran, with everything happening in the
- 4:27Strait of Hormuz and other places around the world, ships being blown up, cargo
- 4:31not getting to where it needs to go, especially with oil and things like that,
- 4:35there's gonna be a demand for safe and fuel-efficient transportation, and we're
- 4:39getting close to seeing that already.
- 4:41And then of course, wind can assist to cut fuel anywhere from 1% to 47%,
- 4:45depending on the number of sails and the wind conditions at the time.
- 4:48So it's never gonna be perfect.
- 4:50It's never gonna be to 100%.
- 4:52I'm not saying we're replacing fuels altogether, but we're getting to a point
- 4:55where we can r-replace almost up to half.
- 4:57And 100-plus ships with wind propulsion installed are estimated
- 5:01to be saving around 100,000 tons of CO2 equivalent per year combined.
- 5:05I think at the beginning of the show, I said they're
- 5:07responsible for 2.1% of that CO2.
- 5:11And that'll be reduced significantly over that time.
- 5:14I don't know what that equates to in terms of percentages, but
- 5:16that's a pretty big chunk.
- 5:18Now, purpose-built wind-assisted ships could see a 50% average
- 5:21reduction in fuel consumption per the International Windship Association.
- 5:25So this is coming.
- 5:26This is already here.
- 5:28To scale it to get to where we want is really difficult, 'cause right
- 5:31now, about one in 500 or one to a thousand ships will have some sort
- 5:36of wind propulsion device on there.
- 5:38But it doesn't necessarily mean that everybody's gonna have them.
- 5:41To scale that is going to be difficult.
- 5:44But the barrier really is the way the commercial contract structure is set.
- 5:49So essentially, the primary obstacle for wind-assisted propulsion in
- 5:52global shipping is now commercial rather than technological.
- 5:55So the technology is there, but shipping's long-established commercial
- 5:59model separates ownership from the actual operation, so the charter.
- 6:03So the owners invest in vessels and onboard technologies, while
- 6:06charterers typically control fuel consumption and voyage decisions.
- 6:11So this creates a split incentive.
- 6:13So owners bear the cost of installing efficiency technologies,
- 6:16but charterers who control fuel decisions capture the immediate
- 6:19financial and environmental benefits.
- 6:21So fixing this would take standardized charter agreements
- 6:24that split costs and savings fairly.
- 6:27There's still a lot of things that have to do with the infrastructure of the shipping
- 6:30industry, which I don't know much of.
- 6:31I'll be honest.
- 6:32I don't know much about how this all works.
- 6:34But if there's a separation between the owner incentive and the charterer's
- 6:37incentive, and the owners will be building the fuel efficiency part,
- 6:40will be building like the upfront cost and paying for the capital, and
- 6:43the charterers are more for the fuel efficient, like actually spending on fuel.
- 6:46So that, you know, they might work together and be like, "Hey, we
- 6:48can both make money off of this."
- 6:50But that's something that's, gonna be a question in the future, and
- 6:53probably one of the biggest challenges.
- 6:54Now, the International Maritime Organization's 2023 strategy formally
- 6:58recognized wind and other zero or near zero technologies as part of
- 7:01the path to decarbonization targets.
- 7:04No dedicated subsidies exist yet for wind propulsion systems in most regions.
- 7:09So adoption is gonna be driven by rising carbon costs, so the carbon
- 7:12offset cost, and regulation rather than direct government incentives.
- 7:16Now even think about everything that's happening now in the world
- 7:18with oil and gas going up and down depending on what's happening, and
- 7:21diesel going up and down and being very, very expensive at this point.
- 7:25Shipping is gonna get more expensive, which is gonna make
- 7:27our products more expensive.
- 7:28Being able to increase fuel efficiency by reducing fuel costs is gonna be probably
- 7:32at the top of the list for a lot of these shipping companies and even the
- 7:35companies who use shipping to get their products to you at a specific time.
- 7:40Of course, EU as the EU always is, the funded research projects called
- 7:44WAS or Sail Horizon or Optiwise are supporting sea trials and
- 7:47validation in the North Sea region.
- 7:49So there are things that people can do with all of this
- 7:53happening around us, right?
- 7:54There are things that we can look at, there are things that we could
- 7:58spend time at and experiment, but we have to go faster than normal.
- 8:02And I like how the wind aspect is, moving forward with this type of technology.
- 8:07So I think it's really good.
- 8:08Now, stuff that you can do is you can look for shipping and logistics
- 8:11companies that disclose emissions data and wind-assist adoption when choosing
- 8:15brands that ship internationally.
- 8:17That information is not always easy to find.
- 8:19I'm gonna be honest, like I had trouble looking for that.
- 8:21But if you have a product that's shipping from say, the east to the west or vice
- 8:25versa, you would wanna look at what type of companies they use to ship.
- 8:28I think they should be saying if they wanna be transparent in their supply
- 8:32chain so that people know - like where all this comes from, how
- 8:35it gets there, how advanced.
- 8:36'Cause that I think is a benefit to talk about is, "Hey, look, our ship
- 8:39uses wind propulsion to get to where you are, so we reduce CO2 emissions,
- 8:44and we increase fuel efficiency, which helps in the pricing of your product."
- 8:48And for consumer relations, I think that's a big deal, but I don't know if
- 8:51the industry thinks that's a big deal or companies actually care about that.
- 8:54But that's something that I care about.
- 8:56That's something you can ask your products, the people that sell
- 8:58your products, you can ask them to do that, but I don't know if
- 9:01that'll actually ever happen.
- 9:02Now, of course, obviously we can support the policy conversations pushing
- 9:05the IMO's 2030 and 2050 targets of eventually going net zero, near net
- 9:10zero as they stay pretty ambitious.
- 9:12Old technology is solving a modern problem.
- 9:15Like think about that.
- 9:16Using sails, using winds is still solving a modern problem.
- 9:19And I think that's a real shift in looking at decarbonization.
- 9:23It's a matter of like, hey, how do we make sure that like going back to the
- 9:27old ways might take a little longer, or if we use it in combination, might not
- 9:31take a little longer, but when we can use wind, that would be much better.
- 9:34You can travel quite fast with wind using as propulsion.
- 9:37And I think that's like an interesting concept to say, let's go back in
- 9:40time, and let's look at what worked before, so we don't have to worry
- 9:43about what works in the future.
- 9:45Sometimes using fuel is not a good idea, especially in the type of world we're
- 9:49living in right now, where we're seeing the direct climate change consequences
- 9:54happening in front of our eyes.
- 9:56This week is all going to be about looking at ways that we can be more
- 10:01efficient within businesses and what businesses are doing to be more
- 10:03efficient, like the shipping industry.
- 10:05I thought that was kind of important, especially with our guest, Alexandre
- 10:08Mongeon, who's gonna be joining us.
- 10:10We're gonna be talking about electric motors for boats, which
- 10:13I think is always interesting.
- 10:14And tomorrow, we're actually gonna be spending more time on boats.
- 10:17We're gonna be looking at boat-sharing economies, just like ride-share.
- 10:20And so we're gonna see where that's gonna take us.
- 10:22And later on, we're gonna be talking about 4Oceans and their business model,
- 10:26and how we can earn living wages on the Thursday's episode in coastal action.
- 10:30So we're gonna be talking about all of that this week.
