General news about geologic CDR

China continues to emphasize low-cost, biologic carbon-removal approaches such as afforestation and soil-turning, leaving geologic methods like direct air capture, enhanced rock weathering, and ocean alkalinity enhancement largely confined to research papers and small pilot projects. Despite vast geological storage potential and emerging university-led efforts, high costs, regulatory gaps, and technical uncertainties keep geologic CDR on the sidelines for now. Full article >>

A new study argues that planners should avoid betting on any single carbon-removal technology and instead build “option-rich” portfolios that can adapt as land availability, energy supply and technological performance evolve. Modeling thousands of plausible futures, the authors find that robust strategies rely on a mix of methods—from near-term forest and soil approaches to later-century DAC and ocean alkalinity—underscoring how climate uncertainty favors flexibility over precision.
