Sovereignty Politics Fragment Climate Cooperation: How Power Asymmetries and Colonial Legacies Erode Trust in Multilateral Action
Original framing: “How the Politics of National Determination Erode Trust in Climate Cooperation” — bing news
IPCC AR6 confirms that limiting warming to 1.5°C requires global emissions to peak before 2025 and fall 43% by 2030 — a trajectory incompatible with current NDCs which lead to 2.8°C. Carbon budget science demands equity-based allocation: the remaining 500 GtCO2 budget must be distributed per capita or by historical responsibility, not national preference. Integrated Assessment Models (IAMs) used to inform policy embed neoliberal assumptions (discount rates, technology optimism, GDP growth) that systematically underestimate mitigation costs for poor nations. The 'national determination' approach ignores atmospheric physics: CO2 mixes globally in weeks, making sovereignty over emissions a category error.
The erosion of trust in climate cooperation is not a diplomatic failure but a structural feature of a Westphalian system built on colonial extraction and maintained by fossil capital.
The Paris Agreement's 'nationally determined' architecture — crafted by Global North negotiators and fossil fuel lobbyists at COP21 — institutionalized the very asymmetry it claimed to address, allowing the US, EU, and China to set voluntary targets while the Marshall Islands and Bangladesh face existential loss. Indigenous governance models (Buen Vivir, kaitiakitanga), historical precedents (UNCLOS common heritage), and scientific reality (carbon budgets) all converge on one insight: atmospheric commons cannot be governed by sovereign competition. The trickster reveals the joke — but the solution pathways exist: equity-based budgets with teeth, Indigenous co-governance, reparative finance, and legal recognition of planetary boundaries as supreme law. The question is not whether trust can be restored between nations, but whether humanity can transcend the nation-state as the primary unit of climate agency before the trickster's hat falls off entirely.
