Geoengineering and carbon management: Is there a meaningful distinction?

A broad and expanding suite of responses to the CO₂-climate problem have been proposed ranging from energy conservation to the construction of space-based sunshields that could counter some of the effect of increasing CO₂. Proposed measures vary widely along many dimensions including their technological feasibility and their distribution of costs, benefit and risks. Here I focus on assessment of industrial carbon management (ICM), defined as the linked processes of capturing the carbon content of fossil fuels while generating carbon-free energy products such as electricity and hydrogen and sequestering the resulting CO₂. Put simply, I address the question: Is ICM an advanced emissions control technology or is it geoengineering?
