Enhanced Weathering Brings Carbon Removal and Farm Benefits to Smallholders
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?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
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?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
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: Mati Carbon is scaling enhanced weathering across the Global South to remove atmospheric CO2 while improving soil health and crop yields for smallholder farmers, creating dual climate and economic benefits.
📈 One key stat: Mati deployed over 150,000 tons of basalt across more than 15,000 acres, resulting in an average 15% increase in crop yields and 65% of farmers reporting reduced pesticide use.
💬 One key quote: “We’re creating the world’s largest EW dataset in smallholder settings. This dataset, developed from high-throughput sampling across diverse soil types and regions, will help us build robust models that gradually reduce the need for high-cost testing.”

1️⃣ The big picture: Mati Carbon is revolutionizing climate action by making enhanced weathering accessible to smallholder farmers across the Global South. As a $50 million XPRIZE winner, they’re applying crushed basalt to farmland where it naturally reacts with CO2 to form stable bicarbonates, locking carbon away for over 10,000 years. Beyond carbon removal, their approach improves soil health, boosts crop yields by an average of 15%, and reduces the need for fertilizers and pesticides. By focusing on regions often overlooked in climate investments, Mati is building resilience in communities most vulnerable to climate change impacts.
2️⃣ Why is this good news: Enhanced weathering creates multiple layers of positive impact, from carbon sequestration to agricultural benefits. Farmers see immediate advantages with healthier soil and increased crop yields, while gaining economic opportunities without any costs to participate. The approach creates local jobs in remote regions where employment opportunities are limited. By delivering verified carbon credits to buyers like Frontier and Shopify, Mati connects rural communities to global climate finance streams. Their focus on the Global South ensures climate solutions benefit regions most exposed to climate change impacts yet historically underrepresented in carbon markets.
3️⃣ What’s next: Mati plans to use their $50 million XPRIZE funds to expand operations into high-impact geographies across India, Africa, and Southeast Asia. They’ll continue developing their R&D capabilities to build the scientific foundation and infrastructure needed for gigaton-scale carbon removal. Additionally, Mati is creating a platform that agritech companies, village entrepreneurs, and other organizations can use to run enhanced weathering programs in their own regions.
