As yet, there’s no agreed methodology for measuring the rate of carbon removal, which depends on factors like soil chemistry and dust consistency. If successful, this approach to carbon removal could help counteract an impact of climate change—ocean acidification that threatens shellfish and other species. Carbon-Hungry TreesLiving Carbon, a Hayward, Calif.-based biotech company, is approaching carbon removal on a micro scale. Fine-tuning trees for carbon removal could also come at the expense of biodiversity, if the result is homogeneous forests planted for carbon credits, experts say. Living Carbon is also experimenting with algae species that produce a highly durable biological polymer.
