The big idea: Paper 3 gives you unseen stimulus on an environmental challenge and asks you to bring real-world cases to it.
What you do with the cases
- Analyse the stimulus.
- Recommend a response.
- Synthesise a judgement.
This capstone shows how to build a toolkit of environment cases and deploy them so any environmental stimulus becomes answerable.
Build a toolkit of environment cases
The recurring environmental tensions: Whatever the stimulus, an environmental challenge usually raises one of these tensions: national interest vs collective action (climate), conservation vs development, voluntary vs binding governance, and who benefits vs who bears the harm (justice). Identify which tension the stimulus raises, and you know how to structure your answer.

As with borders, a good environment case is chosen because it lets you make analytical points, not because it is dramatic. Prepare each case as a tool.
How to prepare an environment case
Pick contemporary & clear
A recent, well-documented case where the environmental challenge and the actors are clear.
Map causes & actors
The causes (emissions, extraction, weak governance), the actors (states, IGOs, firms, communities) and their power and interests.
Name the tension & justice
Which environmental tension it raises, and who benefits vs who bears the harm.
Track the response
What was tried — treaty, payment, regulation, compensation — and how well it worked. This is your evaluation material.
Worked example — turning a case into an answer: Suppose the stimulus is about a climate-finance gap. Deploy a case in five parts.
Deploying the case
CAUSE
A borderless collective action problem; rich states caused most emissions.
ACTORS
Rich states (should pay), poor states (need funds), industries (resist), NGOs (pressure).
TENSION + JUSTICE
National interest vs collective action; causers benefit, sufferers pay.
RESPONSE + EVALUATION
A voluntary pledge was made, but finance under-delivered.
RECOMMENDATION
Rich states lead cuts + deliver finance + binding transparency.
Notice you never narrated events: every part of the case did analytical work. That is how Paper 3 wants cases used.
The key point: Prepare a small toolkit of contemporary environment cases (climate/governance, conservation, justice), and for each know the causes, actors, tension and response. In the exam, use the case to analyse the stimulus and justify a recommendation — never narrate. A well-deployed case is what turns environmental knowledge into marks.

The examiner rewards the same four moves on every environment question. Master them and any stimulus becomes answerable.
The four moves of a Paper 3 answer
Understand the stimulus
Read the unseen material and show you grasp the environmental challenge it presents (AO1).
Analyse with a case
Break the challenge down — causes, actors, tension, justice — using your case and the stimulus (AO2).
Recommend
Propose and JUSTIFY a course of action — the Paper-3-specific skill (AO3).
Synthesise & judge
Pull the material together into a balanced, evaluated judgement answering the exact question (AO3).
The environmental recommendations to have ready
Most environmental recommendations combine: aligning incentives so green choices pay (pricing, cheap clean tech), fair burden-sharing and finance (the rich and the causers pay), giving the vulnerable a voice, strengthening transparency and monitoring, and involving non-state actors. Adapt these to the specific challenge.
Why environment questions always have a justice angle
Nearly every environmental challenge distributes benefits and harms unequally — across countries, communities and generations — so a strong answer always asks who benefits, who bears the harm, and how the response can be made fair, not just effective.
Effective AND fair: The best environmental recommendations are both effective (they actually reduce the harm, by aligning incentives and enforcement) and fair (they share the burden justly and protect the vulnerable and future generations). A response that is effective but unjust — or just but ineffective — is incomplete. Aim for both.
How to nail a Paper 3 environment question: Read the stimulus, then work through the moves below. Use the stimulus AND your own case throughout.
The moves
Name it
Name the environmental challenge and the tension it raises.
Analyse
Deploy a prepared case to analyse it.
Weigh
Weigh the options.
Recommend
Recommend an effective AND fair response.
Synthesise
Synthesise it all into a judgement.
Stimulus + case, every step of the way.

Common mistakes (Paper 3): 1. Narrating the case. Use it to make points.
2. Ignoring the stimulus. Weave it in.
3. No recommendation. Paper 3 demands a justified course of action.
4. Effective but unfair (or vice versa). Aim for both.
5. No synthesis. Pull it into one judged answer.
