Technical Assessment of Potential Climate Impact and Economic Viability of Biochar Technologies for Small-Scale Agriculture in the Pacific Northwest

Summary

This technical assessment evaluates the climate impact and economic viability of biochar technologies for small-scale agriculture in the Pacific Northwest of the United States. The region faces significant climate challenges, including a projected 3°F to 6°F temperature increase and 5-10% less summer precipitation by 2100. The assessment identifies up to 5.7 million tons of biomass carbon annually available for biochar production at $100/dry ton. While initial carbon credit costs for biochar production are high (e.g., $264-$434 per tonne CO2e for modern systems), biomass subsidies and robust life cycle assessments can significantly reduce these costs, potentially to as low as $17-$39 per tonne CO2e for woody trimmings when displacing slash pile burning. The voluntary carbon market, valued at over $2 billion in 2022, is projected to grow to $200-$550 billion by 2050, with biochar credits trading above $108 per ton on platforms like Puro.Earth, suggesting a promising pathway for funding biochar implementation.
