The big idea: Environmental governance is how the world tries to run the environment, with no world government to enforce it.
How it works, and where it breaks
- It works through treaties, IGOs, summits and NGOs.
- Its constant weakness is enforcement: rules exist, but sovereign states can ignore them.
- So governance often lags behind the problem.
- Treaties & agreements — states negotiate rules (on climate, ozone, biodiversity, pollution).
- IGOs — bodies like the UN Environment Programme coordinate action and science.
- Summits — global conferences where states set goals and raise ambition.
- Non-state actors — NGOs, scientists, cities and companies shape norms and pressure states.
The enforcement gap — again: Like all global governance, environmental governance runs into the enforcement gap: there is no world government to make a state keep its promises.
Why the gap matters
- Agreements are usually voluntary, so a state can sign a treaty and then fall short.
- Powerful states or industries can block or weaken rules.
- So environmental governance relies on cooperation, transparency and pressure rather than force.
- That is both its strength (near-universal) and its weakness (often too slow).

Environmental governance has real successes — but also famous failures. Comparing when it works and when it doesn't reveals what makes governance effective.
When environmental governance works
It works best when the problem is clear, the solution is affordable, alternatives exist, and the costs are shared fairly — as with the global agreement that phased out ozone-destroying chemicals, where cheap substitutes and clear science produced near-universal compliance and healed the ozone layer. Clear science + affordable solution + fair burden = success.
When it fails
It fails when the costs are huge and unevenly shared, powerful industries resist, the science is politicised, and there is no cheap alternative — as with climate change, where deep economic interests, free-riding and weak enforcement have kept action lagging behind the science for decades. Big costs + strong resistance + weak enforcement = failure.
Case study — a governance success vs a governance struggle: Contrast two cases: the ozone layer, a rare, clean win for environmental governance, and climate change, which has been far harder.
Ozone layer: success
- The science was clear.
- Cheap substitute chemicals existed.
- Nearly every country agreed a binding phase-out.
Climate change: struggle
- The costs of cutting fossil fuels are huge and unevenly shared.
- Powerful industries resist.
- Agreements are voluntary, so action has lagged for decades.
What the contrast teaches
- Governance works when the solution is affordable and the burden is fair.
- It struggles when it threatens powerful interests and relies on voluntary promises.
- The HL lesson: effective governance depends less on the rules themselves than on aligning incentives, so that compliance is in states' interest.
The key point: Environmental governance manages shared problems through treaties, IGOs, summits and non-state actors, without a world government.
When it succeeds and fails
- It succeeds when the science is clear, the solution affordable and the burden fair.
- It fails when costs are huge, interests are threatened and enforcement is weak.
- So the key to effective governance is aligning incentives and sharing the burden, not just writing rules.

Can voluntary governance ever be enough, or do we need binding global rules — even a stronger world environmental authority? And who should lead it? Weigh it — and recommend.
The case for stronger, binding governance
Because voluntary pledges are too weak for urgent, high-cost problems like climate change, some argue for binding rules with real penalties, stronger international environmental institutions, and perhaps a World Environment Organisation with teeth — governance that can compel, not just recommend.
Why binding global authority is so hard
States guard their sovereignty and will not accept an authority that can override their economic choices, powerful states and industries block strong rules, and enforcement across borders is near-impossible — so a binding world environmental government is politically unattainable, meaning realistic reform means strengthening cooperation, not replacing it.
Two perspectives — weigh them: One view: only binding, enforceable governance can meet urgent environmental threats. Another view: given sovereignty, voluntary cooperation strengthened by transparency and incentives is the realistic path.
The strong HL judgement
- A binding world environmental authority is unattainable.
- So the answer is to strengthen voluntary governance.
- Strengthen it with clear targets, monitoring, finance, aligned incentives and fair burden-sharing.
- Then cooperation becomes effective without a global enforcer.
How environmental governance comes up in Paper 3: Paper 3 stimulus might show a treaty, a summit or a governance failure.
What to do with it
- Analyse WHY governance works or fails (enforcement gap, incentives, interests).
- Then recommend how to strengthen it.
- Usually: aligning incentives + finance + transparency, not an unattainable world authority.

Common mistakes (Paper 3): 1. Assuming rules = results. Enforcement and incentives decide.
2. Calling for a 'world environmental government'. It's unattainable.
3. Ignoring why ozone succeeded but climate hasn't. Compare them.
4. Forgetting non-state actors. They drive governance too.
5. Only describing. Analyse + recommend.
