lhorizon

Lhorizon is a term used in various disciplines to denote a boundary or horizon extended into the future. In theoretical and applied contexts, lhorizon commonly refers to long-horizon analysis or planning, where decisions are evaluated over extended time frames rather than near-term outcomes. The exact definition of lhorizon varies by field, and there is no single standardized interpretation.

In economics and climate policy, lhorizon describes the span over which models project outcomes, allowing evaluation of long-run effects, intertemporal trade-offs, and deep uncertainty. In decision theory and strategic planning, lhorizon emphasizes scenario analysis, resilience, and adaptive strategies to cope with future states that lie far ahead of the present.

Because lhorizon is used informally across disciplines, references to it often require clarification of the horizon length, the uncertainty treatment, and the modeling approach. Common related concepts include long-run forecasting, horizon scanning, and the time horizon in project evaluation.
