Gaseous Carbon Waste Streams: Utilization Status and Research Needs

National Research Council https://bit.ly/2EwJbu3 In the quest to mitigate the buildup of greenhouse gases in Earth’s atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can … Continue reading

Deep Decarbonization as a Risk Management Challenge

Rand Corporation/ by Robert J. Lempert, Horacio R. Trujillo https://www.rand.org/pubs/perspectives/PE303.html Deep decarbonization—reducing net human greenhouse gas emissions to zero in the 21st century—is best pursued as a risk management challenge. This Perspective explores three concepts that are particularly important to the implementation of risk management for deep decarbonization—risk governance, complexity, and robustness. Risk governance provides a … Continue reading
