Science magazine recently published an article co-authored by Klaus Lackner, Director of the Center for Negative Carbon Emissions at Arizona State University. The article, “Net-zero emissions energy systems,” examines the possibilities and challenges facing the decarbonization of energy use — as in, developing an energy system that does not add carbon dioxide to the atmosphere. Decarbonizing energy use would ease the dangerous effects of climate change. Eliminating emissions from some services, such as local travel, heating and cooling, would be relatively simple, but emissions from some essential services would be difficult to curtail. In the report, Lackner and the authors discuss the complexities facing the decarbonization of certain energy sectors, such as air travel, cement production and the provision of a reliable electricity grid. They outline research and development areas that are crucial to achieve this goal of net-zero emissions in energy systems. Read the full article in Science magazine.
