🔬 Top Story: Cornell Study Puts ERW at Up to 1.1 Billion Tonnes/Year by 2100 A new study in Nature Communications Sustainability by Cornell’s Chuan Liao and colleagues models realistic adoption scenarios for enhanced rock weathering (ERW) — the practice of spreading crushed silicate rocks (like basalt) on agricultural fields to accelerate natural CO₂ drawdown. The findings: 350M–750M tCO₂/yr by 2050 and 700M–1.1B tCO₂/yr by 2100. That’s far below earlier theoretical ceilings of 5 Gt/yr but still a massive contribution to climate mitigation. A key takeaway: the Global South would eventually surpass the Global North in ERW deployment as supply chains mature, making the technique a potential equity lever for global carbon markets.

Mercedes F1 Goes All-In on Carbon Removal — 7 New Projects Across 6 Pathways

Formula 1 teams aren’t usually associated with carbon removal. But Mercedes-AMG PETRONAS just made one of the most diversified CDR investments any sports organization has ever announced. Seven Projects, Six Pathways The team added seven new removal projects covering: Direct Air Capture (DAC) Biomass Storage Bioenergy with Carbon Capture and Storage (BECCS) Biochar Ocean Alkalinity Enhancement (OAE) Enhanced Rock Weathering (ERW) Combined with earlier investments through Frontier and Chestnut Carbon, the total portfolio now covers approximately 18,900 tCO₂e across Brazil, Canada, the US, UK, Denmark, and India. The portfolio is curated by CUR8, a carbon removal marketplace focused on rigorous project evaluation. ...
