Mitsubishi and Alt Carbon Expand CO2 Reduction with 70% Less Energy
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.

📰 The quick summary: A new partnership between Mitsubishi Corporation and Alt Carbon will scale enhanced rock weathering carbon removal technology across South Asia, enabling large-scale and durable CO2 removal that benefits local farmers.
📈 One key stat: Alt Carbon’s enhanced rock weathering technology can store captured CO2 in the ocean for over 10,000 years, providing an extremely long-term carbon removal solution.
💬 One key quote: “Having an institution like Mitsubishi Corporation recognize and support our efforts entrenches our belief in the science and technology behind ERW for carbon removal,” said Shrey Agarwal, Co-founder & CEO of Alt Carbon.

1️⃣ The big picture: Mitsubishi Corporation and Alt Carbon have formed a strategic partnership to expand enhanced rock weathering (ERW) carbon removal technology across South Asia. The collaboration centers on Alt Carbon’s innovative approach of spreading crushed basalt rock on agricultural land, which naturally absorbs CO2 when it interacts with rainwater. This absorbed carbon dioxide then gets stored in the soil before eventually making its way through water systems to the ocean, where it remains locked away for thousands of years. The partnership combines Mitsubishi’s scale and resources with Alt Carbon’s proven ERW technology and local expertise in India, positioning them to become a major player in the carbon removal industry across the Global South.
2️⃣ Why is this good news: This partnership marks significant progress in scaling practical carbon removal solutions in developing regions. The technology not only removes CO2 from the atmosphere but also provides benefits to local farmers through improved soil conditions. The process uses 70% less energy compared to other carbon removal methods, making it more sustainable and cost-effective. The extremely long storage duration of over 10,000 years in ocean sinks provides confidence in the permanence of the carbon removal. Additionally, the project helps establish India as an emerging hub for climate technology innovation.
3️⃣ What’s next: Alt Carbon plans to expand its operations across South Asia with Mitsubishi Corporation’s support. The company will continue rigorous testing and modeling of its operations and technology to optimize carbon removal efficiency. The partnership will focus on scaling up the spreading of crushed basalt rock across more agricultural areas while maintaining their stringent testing measures for generating carbon removal credits. They aim to establish India as a major hub for carbon removal technology and implementation.
