Abstract
Summary: In “The Grand Objectives: A Framework for Prioritized Grouping of Environmental Concerns in Life‐Cycle Assessment”. Thomas Graedel (1997) proposed an elegant schema for prioritizing environmental concerns. It operates at three levels: grand objectives, environmental concerns, and targeted activities. I argue that consensus is most likely on the first and third levels, but that the middle level, environmental concerns, is more problematic. Even among individuals who agree on general societal directions, strong differences of views can occur regarding specific technologies. I illustrate by applying Graedel's system to his “radionuclide” category, under his first grand objective (human species extinction). I use the example of nuclear waste to illustrate how values are inextricably involved at the “environmental concerns” level. My analysis suggests ways to enhance the utility of Graedel's useful system.
