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,

📰 The quick summary: UNDO Carbon’s enhanced weathering technology has won the XPRIZE Carbon Removal competition, proving that scaling carbon removal can permanently lock away CO2 while improving soil health for farmers.
📈 One key stat: UNDO’s project in eastern Ontario removed 1,209 tonnes of CO2 across 102 farms and enriched 5,670 hectares of land, demonstrating the real-world effectiveness of enhanced weathering.
💬 One key quote: “Enhanced weathering accelerates a natural process where rocks naturally react with CO2 and water to form stable carbonates that lock away carbon for over 100,000 years.”

1️⃣ The big picture: UNDO Carbon has developed an enhanced weathering solution that accelerates the natural process of carbon capture by spreading crushed mineral-rich rock on farmland. Their approach permanently removes CO2 from the atmosphere while simultaneously improving soil health and crop yields for farmers. Recently recognized as a winner of the prestigious XPRIZE Carbon Removal competition, UNDO has proven the viability of their solution through successful implementation across hundreds of farms. With the potential to remove up to 4 billion tonnes of CO2 annually, this technology represents a scalable approach that combines climate action with agricultural benefits.

2️⃣ Why is this good news: Enhanced weathering offers multiple environmental and economic benefits beyond carbon removal. The technology helps farmers by enriching soil health, increasing crop yields by up to 15%, and reducing the need for expensive inputs like lime and chemical fertilizers. By providing mineral-rich rock to farmers at no cost, UNDO makes this climate solution accessible while creating green jobs in rural communities. The company’s decentralized model empowers thousands of project developers, mining companies, and farmers to participate in carbon removal efforts. With permanent carbon storage lasting over 100,000 years, enhanced weathering represents a durable climate solution with immediate agricultural co-benefits.

3️⃣ What’s next: UNDO plans to reinvest their XPRIZE winnings into cutting-edge scientific research and scaling operations with new and existing partners. They’re building comprehensive datasets at Sentinel Sites to improve modeling and reduce costs. The company is also testing innovative measurement approaches like neutron scattering with partners like UCL to make carbon measurement more scalable and cost-effective.
