The one-sentence truth: Environmental vocabulary matters because sustainability questions are arguments about time, scarcity, risk, distribution and whether present benefits create future costs.
Use the Top 100 General Paper Vocabulary Words for JC1 as the core inventory, with the wider JC1–JC2 vocabulary guide as the conceptual parent.
Core vocabulary
- mitigation — reducing the scale of environmental harm.
- adaptation — adjusting to effects that cannot be fully avoided.
- resilience — capacity to absorb shocks and recover.
- biodiversity — variety of life across genes, species and ecosystems.
- depletion — reduction of a resource through use.
- conservation — protection and careful management of natural resources.
- transition — movement from one system to another.
- externality — environmental costs or benefits not fully reflected in prices.
- intergenerational equity — fairness between present and future generations.
- carrying capacity — the level of use an ecosystem or system can sustain.
Mitigation is not adaptation
Mitigation tries to reduce the cause or scale of harm; adaptation reduces vulnerability to consequences. Climate policy often needs both.
Sustainability is a systems concept
A practice may be profitable today yet unsustainable if it depletes resources, damages ecosystems or creates costs that accumulate later. Time horizon is therefore central.
Externalities explain why markets can underprice harm
If pollution costs are borne by communities rather than producers or consumers, private prices can understate social cost. This vocabulary helps explain carbon pricing, congestion charges and environmental regulation.
Resilience is not the same as prevention
Resilience accepts that some shocks will occur and asks whether systems can absorb them. Flood barriers, diversified energy systems and ecosystem restoration can all strengthen resilience.
Before-and-after language
Weak: “We must protect the environment for the future.”
Stronger: “Intergenerational equity requires present consumption to account for resource depletion and long-term environmental externalities.”
Weak: “Climate change needs many solutions.”
Stronger: “Effective climate policy combines mitigation that reduces future warming with adaptation that lowers vulnerability to impacts already becoming unavoidable.”
Paper 1 and Paper 2 use
Environmental essays improve when students distinguish mitigation, adaptation, resilience and transition costs. In Paper 2, these abstractions help compress examples without losing causal structure.
The deeper lesson
Sustainability vocabulary gives students a way to reason across time: what we gain now, what we deplete, what risks accumulate and who eventually pays.
