Shoosmiths, a prominent United Kingdom-based law firm, has signed a five-year pre-purchase forward offtake agreement with carbon asset developer Carbonaires to secure certified carbon dioxide removal credits. Under the terms of the contract, the underlying environmental assets will be generated by the women-led biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More producer HUSK, which maintains commercial operations in Cambodia and Vietnam. Carbonaires acted as the transaction facilitator by identifying the development project, executing institutional-grade commercial and technical due diligence, structuring the forward contract, and managing the carbon removal lifecycle through to ultimate credit retirement. The multi-year transaction forms a core component of the law firm’s corporate sustainability strategy to systematically offset its residual operational footprint

The primary challenge addressed by this structural agreement is the heightening competition and price volatility within the voluntary carbon market for high-integrity carbon dioxide removals. As corporate demand for verifiable, long-term carbon sequestration accelerates globally, organizations face market constraints in securing reliable, multi-year volume commitments at predictable price points. Simultaneously, corporate buyers must navigate strict greenwashing scrutiny, necessitating carbon removal assets that possess long-term structural permanence and rigorous third-party certification. For professional services firms aiming to neutralize their unavoidable scope 1 and scope 2 market-based emissions, the lack of structured forward offtake mechanisms presents a barrier to achieving near-term net operational zero objectives.

To resolve these market constraints, Carbonaires deployed a structured forward purchase framework that links corporate capital directly to HUSK’s established production infrastructure in Southeast Asia. HUSK utilizes localized agricultural residues, specifically rice husks, as the primary feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More to manufacture a stable biochar product capable of structurally sequestering carbon dioxide for more than 1,000 years. This decentralized production model provides a dual benefit by generating carbon removal credits while concurrently delivering nutrient-rich soil inputs to regional agricultural sectors. The integrity of the resulting carbon removal credits is validated by a six-year track record of independent certification under the Global Biochar C-Sink Standard, providing the verified tracking required by institutional compliance standards.

The long-term outcome of this multi-year commercial agreement is the guaranteed stabilization of high-integrity carbon credit supply and pricing for Shoosmiths over the five-year operational window. The law firm successfully combines these verified removals with its existing 70% reduction in scope 1 and scope 2 emissions, bringing its net operational emissions to zero as it progresses toward a comprehensive 2040 net-zero target. In the production regions of Cambodia and Vietnam, the offtake funding supports the regeneration of more than 6,400 hectares of degraded farmland. Furthermore, field trials indicate the distributed biochar application enhances smallholder crop yields, directly resulting in an average increase in regional farmer incomes exceeding 20%.
