Inside Climate News – In a peer-reviewed opinion paper published in Trends in Ecology & Evolution, University of Oxford researchers point out that, although carbon sequestration is a valuable tool for climate action, large-scale tree planting projects often lack biodiversity, which can make them ineffective climate mitigations. The authors warn against using carbon as the sole metric for a forest ecosystem’s importance and argue that carbon sequestration projects need to expand their focus to encompass ecosystem restoration and biodiversity conservation.
