The rich mosaic of soil heterogeneity, and how to navigate its complexities 

by

A critical component of enhanced rock weathering (ERW) projects is quantifying carbon dioxide removal (CDR) at field scale. Carbon dioxide removal with ERW is tracked using multiple phases (gas, liquid, and soil) at InPlanet. In addition to other phases, a key component of monitoring weathering rates is done by analyzing soil samples. Combined with other measurements, determination of weathering rates in soils may be related back to carbon dioxide removal at the field scale. However, to do this suppliers like InPlanet must balance operational feasibility, cost, and data quality. This is a major challenge when determining a standard operating procedure … Read more

Rock powder dissolution and carbon capture: How to best understand it

by

In this blog, Dr Junyao Kang, Data Analysis and Modeling Lead,  and Dr. Matthew Clarkson, Head of Carbon at InPlanet share about Rock Powder Dissolution and Carbon Capture processes, CO₂ capture quantification, and the challenges posed by fertilizers. The dissolution process and cation release At the core of Enhanced Rock Weathering (ERW) is the dissolution of rock powder, which releases essential cations into the soil system. As Dr. Junyao Kang explains: “You can see all these dark particles as our rock powder spreads onto the surface of the soil. We see dissolution happening, releasing important cations for our enhanced rock … Read more

Understanding losses and adjustments to carbon dioxide removal estimates

by

Imagine holding a giant sponge, and your job is to soak up as much water as possible. But along the way, some water drips off, some gets absorbed by other things, and some even turns into steam! This is similar to how scientists try to remove carbon dioxide (CO₂) from the air using special kinds of rock powder. These losses and adjustments in carbon dioxide removal efforts show that, just like our sponge, not all of the CO₂ stays where we want it. Losses and adjustments in carbon dioxide removal are inevitable in this process. Importantly, we can measure these … Read more

Explaining our data collection framework and field monitoring station

Data accuracy is at the core of our work, and our Field Monitoring Station (FMS) plays a critical role in ensuring reliable, science-backed measurements for Enhanced Rock Weathering (ERW). Our Data Collection Framework and Field Monitoring Station work together to collect real-time environmental data. This allows us to track how basalt rock powder interacts with soil, water, and air. Data for crediting is derived from the infield sample points, dispersed across a deployment site. But the FMS is a place we can monitor more intensively for research purposes.  As Dr. Matthew Clarkson, Head of Carbon at InPlanet explains: “We monitor … Read more

What do enhanced rock weathering and Coca-Cola have in common?

by

InPlanet’s Science and Impact Lead, Dr. Philipp Swoboda, our research lead on Rock Powders for Tropical Agriculture and Enhanced Weathering, breaks down Life Cycle Assessment (LCA) and its impact on InPlanet. For a deeper dive, understanding Life Cycle Assessment of Rock Weathering is crucial to appreciating the full scope of our work. To better understand this complex process, we asked Dr. Swoboda to explain InPlanet’s LCA methodologies for our own Enhanced Rock Weathering (ERW) projects. Understanding the life cycle assessment of rock weathering in these projects helps in making informed decisions. What is a life cycle assessment (LCA)? LCA, or … Read more

Issuing a verified carbon credit isn’t simple. It requires precise measurement, strict compliance with evolving regulations, and third-party validation. InPlanet recently announced its development and delivery of certified carbon credits in Enhanced Rock Weathering (ERW) as the first in the world, a milestone for the entire Carbon Dioxide Removal (CDR) industry. As InPlanet’s Head of Carbon, Dr. Matthew Clarkson put it: “To allow us to have the standard to issue that credit, we have to align with scientific best practices, follow strict protocols, and pass independent validation. It’s complex, but it’s what makes our credits truly credible.” The journey of … Read more

Webinar: Matthew Clarkson on InPlanet’s certified ERW credits, issued by Isometric

by
Webinar InPlanet and Isometric

A new milestone for Enhanced Weathering (EW) to play a significant role in large-scale carbon dioxide removal (CDR) while delivering co-benefits to agriculture and soil health. During this webinar hosted by Chris Podgorney, Head of Product at Isometric, Dr. Matthew Clarkson, Head of Carbon at InPlanet, explores how the issuance of these credits raises the bar for quality. What sets them apart is their incorporation of the latest scientific advancements in enhanced rock weathering. These credits are also backed by academic consensus. The carbon credits webinar also explores the operational feasibility of conducting rigorous Monitoring, Reporting, and Verification (MRV) in … Read more

How do we measure carbon dioxide removal?

by
Matthew Christina and Phil in the lab

Quantifying Carbon Dioxide Removal Through Enhanced Weathering: A manuscript Enhanced weathering (EW) is emerging as an exciting new carbon dioxide removal (CDR) technique. Enhanced weathering is scalable now and has a staggering potential to remove gigatonnes of CO2 annually. However, monitoring, reporting, and verification (MRV) of CDR with EW – how we measure its effectiveness – is widely viewed as the biggest barrier to scaling of the technique. Robust MRV is crucial to the widespread operationalization of EW. Ultimately, trust in the EW industry depends on these three letters.   To bring greater transparency to the topic, InPlanet’s research team has … Read more
