Decarbonization of electricity generation can support climate-change mitigation and presents an opportunity to address pollution resulting from fossil-fuel combustion. Generally, renewable technologies require higher initial investments in infrastructure than fossil-based power systems. To assess the tradeoffs of increased up-front emissions

Soils contain the largest pool of terrestrial organic carbon (C) and are a major source of atmospheric carbon dioxide (CO2). Thus, they may play a key role in modulating climate change. Rising atmospheric CO2 is expected to stimulate plant growth

The latest advances in biocatalysis using supercritical carbon dioxide (scCO(2)) are reviewed. Stability and stabilization methodologies of enzymes in scCO(2) as well as reactions for organic synthesis are described. Especially, varieties of examples for lipase-catalyzed synthesis of chiral compounds using
