Nature-based solutions (NbS), defined as actions that address societal challenges by protecting, managing, and restoring ecosystems, are critical to maintaining a healthy planet for all. From a climate perspective, our forests, soils, oceans, and variety of other ecosystems are essential for drawing down carbon and combating climate change. Moreover, NbS provide a variety of key co-benefits, from biodiversity to food production to cultural and economic livelihoods.
As of late, there’s been surging interest in NbS for their carbon removal potential, as their carbon credits offer new financial means for conservation. That said, these credits are susceptible to low prices and raise concerns about permanence, measurement, additionality, and ultimately, greenwashing. So the question is, how should we evaluate NbS, and how can we equitably scale NbS to ensure effective carbon removal?
