A paired concept for analyzing environmental impact at different scales, derived from the principle of the Carbon Region. Microcarbon refers to the emissions directly tied to an individual's conscious choices and lifestyle—their diet, transportation mode, energy usage at home. Macrocarbon refers to the massive, structural emissions embedded in the systems they are forced to participate in—the carbon cost of the national power grid, the military-industrial complex, the global supply chain for every product in their home. It's the distinction between the carbon you choose to emit and the carbon emitted on your behalf just by existing in a modern society.
Macrocarbon and Microcarbon "He's over there calculating the Microcarbon of turning off his lights, while ignoring the Macrocarbon of the data center required to stream his outrage about the environment. One is a rounding error on the other."
