Carbon removal marketplace Supercritical announced a new agreement with Boeing for the purchase of 20,000 tons of durable carbon dioxide removal (CDR), sourced from a series of suppliers pursuing biochar and enhanced rock weathering (ERW) projects in developing countries. Biochar and enhanced rock weathering (ERW) are widely viewed as among the more scalable carbon removal […]

Boeing Buys 20,000-Ton Portfolio of Biochar, ERW Carbon Removals - ESG Today
Abatify Summary
Nature & Climate Perspective
**The diversification into biochar and Enhanced Rock Weathering (ERW) shifts the ecological focus from temporary biological sinks to permanent mineralized storage. **
- Biochar integration provides a dual-purpose benefit by sequestering carbon while improving soil biodiversity and nutrient retention in agricultural LULUCF contexts.
- Enhanced Rock Weathering accelerates natural silicate carbonation, creating stable carbonate minerals that ensure sequestration durations exceeding 1,000 years.
- Unlike traditional forestry projects, these technical removals mitigate the risks of reversal due to wildfires or pests, offering superior environmental stability for long-term climate targets.
Market & Policy Outlook
**Boeing's multi-ton commitment aligns with ICVCM Core Carbon Principles (CCPs) by prioritizing high-integrity, durable removals over low-quality avoidance credits. **
- This transaction strengthens the supply chain for high-durability removals required to meet SBTi Net-Zero Standards for neutralizing residual Scope 3 aviation emissions.
- By purchasing through a marketplace like Supercritical, Boeing provides the financial liquidity necessary to scale nascent ERW and biochar technologies toward price parity with traditional offsets.
- The use of high-permanence removals sets a benchmark for future Article 6.4 mechanism integration, where additionality and robust monitoring, reporting, and verification (MRV) are mandatory.
