Environmental arguments become much more precise when students stop treating “saving the environment” as one objective.
The wider JC1–JC2 vocabulary framework treats issue vocabulary as a way to expose mechanisms, time horizons and trade-offs.
Core climate concepts
- Mitigation: reducing the causes or scale of future climate change.
- Adaptation: adjusting systems to effects that occur or are expected.
- Resilience: ability to withstand disruption and recover.
- Transition: movement from one energy, economic or technological system to another.
- Externality: cost or benefit imposed beyond the immediate decision-maker.
- Intergenerational equity: fairness between present and future generations.
Mitigation and adaptation are not substitutes
Mitigation asks how to reduce future damage; adaptation asks how to live with damage that cannot be avoided. A strong essay can distinguish investment priorities rather than placing every environmental action in one basket.
Transition has distributional costs
A cleaner system can still impose short-term costs on workers, firms or households. Vocabulary such as transition cost, stranded asset, just transition and distributional burden helps students discuss who pays and when.
Sustainability needs a time horizon
A policy can be financially sustainable but environmentally damaging, or ecologically desirable but politically unstable. Specify what must be sustained and over what period.
A stronger argument
Instead of “Governments must choose the environment over the economy”, write: “Climate policy is more durable when environmental costs are internalised while transition burdens are distributed in ways that preserve political and social legitimacy.”
The vocabulary makes the trade-off visible without pretending the goals are mutually exclusive.
Environment and Climate Concept Lab: Think in Systems and Time Horizons
Environmental vocabulary becomes powerful when it lets students distinguish causes, responses, time horizons and distributional effects. “Protecting the environment” is not one action. It includes mitigation, adaptation, conservation, restoration, transition and resilience—and each asks a different policy question.
Mitigation, Adaptation and Resilience
- Mitigation: reduce future drivers or scale of harm.
- Adaptation: adjust to effects that occur or are expected.
- Resilience: maintain function or recover under disruption.
These strategies can complement one another. Adaptation without mitigation may become increasingly expensive; mitigation does not eliminate the need to prepare for impacts already underway.
Externalities and Internalisation
Environmental harm is often an externality: costs fall partly on people outside the transaction. Internalising the externality means bringing more of that social cost into the decision through pricing, regulation, standards or liability. The vocabulary helps explain the rationale behind carbon pricing, congestion charges and pollution controls.
Transition Vocabulary
- Decarbonisation: reducing carbon intensity or emissions.
- Stranded asset: an asset that loses economic value as conditions or policy change.
- Just transition: managing environmental change while addressing burdens on workers and communities.
- Lock-in: infrastructure or incentives that make an existing high-impact system difficult to change.
- Path dependence: earlier choices constrain later options.
Biodiversity, Conservation and Restoration
Biodiversity concerns variation in genes, species and ecosystems. Conservation generally protects what remains; restoration seeks to recover degraded systems. A climate policy can reduce emissions while still damaging biodiversity, so environmental evaluation should not collapse every outcome into carbon alone.
Intergenerational Equity
Climate policy raises a difficult distributional question across time: how much cost should current generations bear to reduce risks faced by future generations? Intergenerational equity, discounting, long-term liability and irreversibility help students explain why future harms may deserve action even when immediate costs are visible today.
Greenwashing and Additionality
Greenwashing describes misleading environmental claims that make an activity appear more sustainable than it is. Additionality asks whether an environmental action creates benefit beyond what would have happened anyway. These concepts help students evaluate corporate claims rather than accepting labels such as “green” or “carbon-neutral” at face value.
Circularity and Resource Efficiency
A circular economy aims to reduce waste through reuse, repair, remanufacture and material recovery. Resource efficiency asks how much useful output is produced per unit of material or energy. Efficiency gains, however, do not automatically reduce total consumption if demand grows quickly—a useful place to discuss rebound effects.
Worked GP Argument
Instead of “economic development should not come at the expense of the environment”, write: “Development is more sustainable when environmental externalities are reflected in prices and planning, while transition support prevents the cost of decarbonisation from falling disproportionately on households and workers with the fewest alternatives.”
Singapore Transfer Questions
- How does land scarcity change the trade-offs around transport, energy and urban greenery?
- Which climate risks require adaptation even if global mitigation succeeds?
- Where can dense urban infrastructure create efficiencies—and where can it create systemic vulnerability?
- How should present cost be weighed against future resilience?
Climate Vocabulary Drill
Choose one environmental policy and evaluate it through five lenses: mitigation, adaptation, distribution, implementation constraint and long-term resilience. Then identify one unintended consequence and one modification that would make the policy more durable.
Balanced environmental writing does not weaken urgency. It makes the pathway from evidence to action clearer by separating goals, mechanisms, burdens and time horizons.
