Restoring Trust: Rebuilding the Forest Carbon Credit System Through Scientific Rigor

open access: yesBiological Diversity, EarlyView.
ABSTRACT As pivotal nature‐based climate solutions (NbCS), forests are increasingly recognized for their climate mitigation potential. However, this potential is undermined by fundamental flaws in current carbon credit systems. Our analysis identifies four interconnected systemic challenges: (1) subjective additionality assessments arising from ...

Extent, characteristics and policy applications of Key Biodiversity Areas

open access: yesBiological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy
