Bio storage only option: UN

摘要

Biological carbon management is the only feasible option for removing carbon from the atmosphere at large, said a UN World Environment Day report.rnBiological removal and storage was preferred to mechanical carbon capture and storage (CCS), as CCS was only appropriate for concentrated carbon sources, such as power stations, said the report, 'The natural fix? The role of ecosystems in climate mitigation'.rnThe biological approach, which uses for example photosynthesising organisms to capture and store carbon dioxide, is also viewed as less costly. "Costs of carbon mitigation via avoided deforestation, especially of tropical peatland, can be very low in contrast with 'clean energy' options (Spracklen et al. 2008)," the report said.
