The need for radical transparency in carbon dioxide removal

by

Carbon Dioxide Removal (CDR) technologies, alongside rapid and deep emissions reductions, are critical to prevent dangerous climate change. However, as the CDR market scales, the safety, integrity and efficacy of these interventions are paramount. A fundamental challenge lies in establishing robust and credible monitoring, reporting, and verification (MRV) frameworks that inspire widespread trust among all stakeholders, from policymakers and investors to the public and scientific community. This is especially true for enhanced rock weathering (ERW), a complex open-system pathway with many remaining open research questions. This necessitates a radical shift towards comprehensive data transparency and shared learnings to advance the … Read more

Sustainability Performance of ERW in Brazil is Exceptional

by

Enhanced Rock Weathering (ERW) is gaining traction as a promising Carbon Dioxide Removal (CDR) technology. Its potential to play a significant role in mitigating climate change is proven and permanent. While ERW is considered comparable to other CDR methods and markets in terms of sustainability, research highlights that the sustainability performance of ERW deployment in Brazil is in fact, exceptional. Brazil’s unique advantages Published life cycle analysis (LCA) showcases Brazil’s unique advantages for ERW, demonstrating its high CDR potential with minimal negative impacts.  Several factors contribute to this “exceptional” sustainability performance: Minimal environmental impacts ERW, in general, exhibits low resource … Read more

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

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
