• Exclusive partnership aims to generate durable ERW-based carbon removal credits in Brazil, potentially removing hundreds of thousands of tonnes of CO2.
• UNDO brings proprietary MRV systems, XPRIZE-winning technology, and buyer relationships; Verde provides large-scale feedstock and agricultural deployment capacity.
• Agreement introduces a new revenue stream for Verde and sets a pathway for gigatonne-scale carbon removal aligned with emerging global CDR demand.
Brazil Becomes New Hub for Enhanced Rock Weathering Deployment
Verde AgriTech has signed an exclusive agreement with UK-based UNDO Carbon to co-develop, measure, and commercialise enhanced rock weathering (ERW) carbon removal credits across Brazil’s agricultural regions. The partnership brings together Verde’s large-scale glauconitic siltstone operations with UNDO’s measurement, reporting, and verification (MRV) platform, creating one of the most structured ERW commercial frameworks announced to date.
UNDO founder and CEO Jim Mann framed the agreement as a turning point for global ERW scale-up, stating:
“The signing of this agreement with Verde demonstrates the potential of UNDO’s end-to-end platform in activating Enhanced Rock Weathering projects globally at pace. By combining Verde’s exceptional mineral resources and operational capacity in Brazil with UNDO’s ERW measurement and technology expertise, we’re creating a blueprint for scaling durable carbon removal. This collaboration is showing that when you bring together complementary strengths, ERW can scale quickly to deliver the gigatonnes of removal the world urgently needs.”
Verde CEO Cristiano Veloso called the partnership a direct route to monetising ERW at industrial scale.
“Today’s exclusive agreement with UNDO creates a clear path to turn Verde’s Enhanced Rock Weathering activities into a scalable revenue stream. By combining our glauconitic siltstone products and established operations in Brazil with UNDO’s award-winning expertise in measurement, reporting, and verification, we aim to originate and deliver durable, high-quality carbon removal credits aligned with global best practices, including leading Enhanced Rock Weathering methodologies.”
Combining ERW Feedstock Scale With Global MRV Infrastructure
The agreement gives Verde the ability to convert its existing mineral operations into a formal carbon removal business line, complementing its fertilizer activities. For UNDO, it secures consistent access to large, mineral-rich ERW feedstock at a time when buyers are prioritising removal projects with scale, permanence, and evidence-based verification.
UNDO has already spread more than 313,800 tonnes of silicate rock across 398 farms, enriching 54,400 acres of agricultural land and setting up the permanent removal of roughly 69,000 tonnes of CO2. In 2025, the company became one of four global winners of the US$100 million XPRIZE Carbon Removal competition funded by the Musk Foundation.
The company’s backing by Microsoft, Barclays, British Airways, and McLaren has accelerated buyer confidence in the ERW pathway, particularly as corporates diversify away from forestry projects and toward durable carbon removal solutions.
Structured Partnership With Defined Commercial Incentives
The agreement includes up to 1.7 million share purchase warrants issued by Verde to UNDO, tied directly to future carbon credit revenues from ERW offtake agreements. Vesting is linked to cash received under credits priced at thresholds of US$350, US$300, and US$250 per tonne, with cumulative targets reaching US$60 million.
This structure mirrors emerging finance models in the engineered carbon removal market, where offtake performance and credit quality determine long-term revenue potential.
Warrants include a three-year exercise period, lock-up conditions, transfer restrictions, and provisions allowing accelerated expiry if share prices reach a defined volume-weighted trading level.

Operational Roles and Market Implications
Verde will handle mineral processing, crushing, logistics, field deployment, and soil sampling across its extensive agricultural network. Its local knowledge of agronomic conditions and climate data is central to ERW success in Brazil’s tropical environments.
UNDO will bring its proprietary MRV protocols, technology platform, and established buyer relationships — elements increasingly seen as prerequisites for large-volume CDR procurement by corporates with science-aligned climate strategies.
The companies describe the partnership as a foundation for entering the market at scale. Verde expects ERW to become a significant new product line, while UNDO views Brazil as a critical geography capable of delivering high-volume, durable carbon removal.
What Executives and Investors Should Watch
Three developments will determine the partnership’s impact:
• The speed at which verified ERW credits can be delivered to global buyers with long-term removal commitments.
• Whether deployment in Brazil can scale toward the hundreds of thousands of tonnes the partners reference.
• The ability of ERW credits to secure multi-year offtake contracts at premium prices as durable CDR markets mature.
A Step Toward Gigatonne-Scale ERW Deployment
Enhanced rock weathering is attracting growing attention from policymakers anticipating the need for gigatonne-scale carbon removal beyond 2030. Brazil’s agricultural land and mineral availability make it one of the most promising deployment environments worldwide.
By aligning feedstock, operational capacity, technology, and commercial incentives, Verde and UNDO are positioning ERW as a structured climate solution capable of entering mainstream carbon markets. If successful, the partnership will contribute meaningfully to the global supply of durable carbon removal credits — a necessity for countries and companies working toward net-zero pathways.
