Research, perspectives, and technical writing from the Earthmover team on carbon removal science, measurement technology, and climate markets.
We are thrilled to announce the close of our $7.2 million seed round, led by Lowercarbon Capital. This funding will accelerate development of our carbon removal measurement and verification platform and expand our team from 22 to approximately 45 people by the end of 2025.

Direct air capture uses industrial chemistry to extract CO2 directly from ambient air. We explain the two main approaches — liquid solvent and solid sorbent systems — their energy requirements, cost trajectories, and why DAC's permanence advantages make it increasingly preferred by corporate buyers.

Soils have lost 70–100 billion tonnes of carbon to the atmosphere through thousands of years of agriculture. This guide covers the biological mechanisms of soil carbon storage, the practices that build SOC, measurement approaches, and what land managers need to know before entering carbon markets.

Carbon credit quality — additionality, permanence, measurability, verifiability — is the central challenge that will determine whether voluntary carbon markets become a genuine climate solution. We examine the quality dimensions that matter most and what both buyers and project developers need to understand.

MRV is the technical backbone of every carbon removal project. This technical overview covers measurement approaches for different project types, the importance of explicit uncertainty quantification, reporting standards and interoperability challenges, verification protocols, and the role of remote sensing and ML in reducing MRV costs.

Biochar converts labile biomass carbon into stable aromatic carbon structures with residence times of hundreds to thousands of years in soil. We examine the chemistry of biochar production, its agricultural co-benefits, feedstock sustainability requirements, and the growing market for biochar carbon credits at $100–$300 per tonne.

The ocean absorbs 25–30% of human CO2 emissions annually. We examine ocean alkalinity enhancement, macroalgae sinking, iron fertilization, and blue carbon ecosystems — assessing the scientific basis, efficiency uncertainties, ecological risks, and measurement challenges for each approach.

Over 5,000 companies have set net-zero targets. How do they build a carbon removal portfolio that is scientifically credible, strategically sound, and resilient to growing regulatory scrutiny? We cover portfolio construction principles, the removal hierarchy, advance market commitments, and disclosure requirements.

The voluntary carbon market contracted 30–50% in 2022–2023 following quality scandals, while demand for high-quality engineered removal credits grew strongly. We analyze the quality flight underway, the ICVCM's Core Carbon Principles, Article 6 developments, supply constraints, and the path to a higher-integrity market recovery.

The global food system accounts for 23–37% of anthropogenic greenhouse gas emissions — and regenerative agriculture practices can help reverse that trend. We examine the science of no-till, cover cropping, managed grazing, and agroforestry, the gap between potential and verified impact, and the markets making regenerative agriculture economically viable.

The IPCC AR6 found that all credible 1.5°C pathways require significant carbon removal. We examine what the IPCC says, how the US, EU, and UK are approaching CDR policy — from the IRA's 45Q tax credit to the EU Carbon Removal Certification Framework — and what critical policy gaps remain.
