Instrumental value is the usefulness an entity has for humans, whereas intrinsic value is the value attached to an entity simply for what it is, independently of its usefulness. These HL-only concepts belong to HL.c Environmental ethics.
How the Two Values Differ
Instrumental value treats nature as valuable because it provides benefits. A forest may have instrumental value because it supplies timber, stores carbon, supports tourism, regulates water flow, or provides medicines.
Intrinsic value means that the forest, its species, or individual organisms are considered worthy of protection in themselves. Their value does not depend on whether humans obtain measurable benefits from them.
| Basis for comparison | Instrumental value | Intrinsic value |
|---|---|---|
| Source of value | Usefulness to humans | Worth simply for what the entity is |
| Typical question | “What benefits does it provide?” | “Does it deserve protection regardless of benefits?” |
| Forest example | Timber, recreation, carbon storage, and water regulation | Species and ecosystems have value independent of human use |
| Likely perspective | Often anthropocentric or technocentric | Often ecocentric |
The categories are not mutually exclusive. For example, a whale may have instrumental value through ecotourism and its role in marine nutrient cycling, while also having intrinsic value because it is regarded as possessing worth and possibly moral standing.
A useful named example is New Zealand's Whanganui River, which received legal personhood in 2017. This reflects recognition extending beyond the river's instrumental benefits and was shaped by the Māori worldview and relationship with the river. It also connects environmental ethics with indigenous perspectives and environmental justice.
The common misconception is that something must have either instrumental or intrinsic value. In IB ESS, the values are not exclusive: the same entity can possess both.
Exam Technique
For a “distinguish” question, define both terms and make the contrast explicit. For “discuss” or “evaluate,” apply both values to a named environmental issue, consider contrasting perspectives, and reach a supported conclusion rather than merely listing benefits.
