A Yale study assesses the criticality of all 62 metals, identifying those at risk due to supply shortages and environmental concerns. The researchers found that some metals used in emerging technologies like smartphones and medical imaging may become difficult to obtain.
A Yale-led study suggests that only 27-34% of world's wood fuel is unsustainable, highlighting the need for nuanced, local-specific climate and forest policies in developing nations. The research also identifies 'hotspots' where deforestation exceeds sustainable yields, primarily in South Asia and East Africa.
A new special feature of Yale's Journal of Industrial Ecology explores how industrial ecology can lead to cost savings and higher profits for businesses. The research highlights the economic and environmental benefits of using life cycle assessment, design for environment, and material flow analysis in supply chains.
A Yale-led study found that removing earthworms, beetles, and other small animals from the soil of a replicated Scottish sheep meadow altered plant species, reduced productivity, and changed the quality of yields. The results highlight the importance of these tiny creatures in maintaining ecosystem balance and services.
A Yale study finds that the conversion of forests to cropland worldwide has reduced global BVOC emissions, leading to a net cooling effect on climate temperatures. The loss of dark-colored forests and reduction in emissions of short-lived climate pollutants have offset warming caused by increased fossil fuel carbon dioxide emissions.
