Affiliate Disclosure

Hey fellow impactful ninja ?

You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.

  • Most of these links are informational-based for you to check out their primary sources with one click.

  • But some of these links are so-called "affiliate links" to products that we recommend.

Why do we add these product links?

First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.

And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.

What do these affiliate links mean for you?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.

What do these affiliate links mean for us?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.

What does this mean for me personally?

You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.

Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

Stay impactful,

1️⃣ The big picture: The maritime industry is witnessing a major breakthrough in sustainable shipping with the Canopée, a hybrid cargo vessel designed to transport Ariane 6 rocket components. Equipped with four OceanWings sails, this innovative ship harnesses wind power to dramatically reduce fuel consumption and carbon emissions. The technology has proven remarkably reliable with 99.6% system availability over two years. At a time when the maritime transport sector accounts for roughly 3% of global greenhouse gas emissions, the Canopée represents a critical advancement toward more eco-friendly shipping practices.

2️⃣ Why is this good news: The Canopée’s impressive efficiency translates to approximately 20 tons of CO2 emissions avoided daily, offering a practical solution to decarbonize the shipping industry. The vessel has even reached speeds of 13.7 knots using sail power alone, demonstrating the viability of wind propulsion for commercial maritime transport. On recent transatlantic voyages, the ship achieved even greater fuel savings of 2.2 tons per wingsail per day. This success has earned recognition from the prestigious French Académie de Marine, highlighting the importance of this innovation for the entire industry. The technology’s seamless integration into daily operations makes it a promising solution for wider adoption.

3️⃣ What’s next: The Canopée will continue serving ArianeGroup’s logistics needs for the next 15 years, providing a long-term test case for wind-assisted propulsion technology. As global regulations around emissions tighten, similar innovations are expected to spread to other sectors of maritime transport. The success of the Canopée will likely inspire more collaborations between technology providers and shipping companies to develop the next generation of sustainable vessels.
