The gap is not primarily a failure of technology or economics — it is a failure of institutional design. Voluntary agreements like the Paris Agreement rest on an optimistic theory of change: that the combination of peer pressure, reputational stakes, and progressive norm-tightening through the ratchet mechanism would generate sufficient political will to close the ambition gap. This theory has been only partially vindicated. The NDCs submitted under Paris are, on aggregate, inconsistent with the 1.5°C target by a factor of roughly two, and the mechanism for tightening them has produced incremental rather than transformational revision cycles. The fundamental issue is that voluntary frameworks cannot resolve the collective action problem at the heart of climate governance: each nation has a rational incentive to free-ride on others' commitments whilst protecting its own economic interests. Mandatory, legally binding frameworks with credible enforcement mechanisms — closer to the WTO model than the Paris model — may be structurally necessary, even if they are politically harder to achieve.

The simulation made viscerally real something that is easily abstracted in academic analysis: every delegation in a real climate summit is simultaneously under domestic political pressure that may be wholly inconsistent with what global science requires. The USA cannot commit to legally binding targets that require Senate ratification in a polarised Congress. China cannot accept frameworks that implicitly deny its continuing development entitlements. Small Island States cannot accept language that treats 2°C as an acceptable outcome when their territories will be submerged. These are not simply bad-faith negotiating positions — they are genuine structural constraints. The key insight is that the failure of climate agreements is not primarily a technical or linguistic problem — it is a problem of misaligned political incentive structures that operate on election cycles of 4–5 years rather than on the multi-decadal timescales of climate causation and consequence. Understanding this does not excuse inaction; it explains the specific reforms — like insulating climate policy from electoral cycles, or embedding it in constitutional or WTO-level frameworks — that might actually work.

It reflects it precisely. The UNFCCC COP process is formally an intergovernmental forum — sovereign states are the decision-making units, and civil society organisations participate as observers, not negotiators. This structure has several consequences. It means that the voices with the greatest moral authority — those of the most climate-vulnerable populations, future generations, and scientific bodies — have no formal veto over outcomes. It also means that fossil fuel lobbyists, registered as industry observers, have access to the same spaces as civil society and, according to analysis by Carbon Market Watch, outnumber climate-vulnerable nations' representatives at some COP events. The NGO role in the simulation also models something important about discourse power outside formal governance: the ability to name, shame, and reframe public narratives operates outside voting structures and has historically driven significant normative shifts (the emergence of the 1.5°C target itself was driven partly by civil society pressure). The limits of formal institutional representation do not exhaust the political possibilities of organised advocacy.

The comparison is likely to be instructive in both directions. If your class produced a more ambitious text — binding 1.5°C commitments, mandatory Loss and Damage, independent verification — this raises the question: what structural constraints on actual negotiators prevented them from doing the same? The answer points to the full weight of geopolitical calculation, domestic political economy, and the multi-layered veto structure of consensus-based multilateralism. If your class produced a similarly compromised text, this is equally revealing: it suggests that the compromises in Glasgow were not simply the result of bad faith or political failure, but of genuine structural constraints that student negotiators — even with the freedom of a simulation — found difficult to escape. Either outcome produces a valuable pedagogical lesson: that the gap between what is scientifically necessary and what is politically achievable is real, persistent, and demands not merely better negotiators but better institutions.
