Ten years after the Paris agreement was celebrated as a civilizational achievement, the numbers tell a brutal story. Global heating is now running at 0.4°C per decade — double the rate when the treaty was signed. The UN's most optimistic estimate puts eventual warming at 1.7-1.8°C, blowing past the 1.5°C target that was supposed to be the agreement's raison d'être. Two consecutive years of temperatures exceeding that threshold have already arrived. The structural failure is architectural. Paris was designed as a voluntary pledge system — countries set their own targets, with no enforcement mechanism. The consensus requirement for all resolutions gives any single bad actor an effective veto. Saudi Arabia, Russia, Venezuela, and allied petrostates have used this repeatedly to obstruct progress. It took more than 30 years of UN climate negotiations before fossil fuels were even mentioned directly, at Cop28 in Dubai in 2023, and even then the resulting language — 'transition away from fossil fuels' — came with no timeframe and no binding policies. The US withdrawal under Trump removes the world's largest economy and source of roughly one in eight tonnes of global CO₂ from the framework entirely. But the rot extends well beyond Washington. Australia, co-hosting Cop31, has set no end date for fossil fuel exports. Turkey, the other co-host, plans to increase carbon output. The UK is opening a new gasfield. Germany has scrapped its renewable heating law and dropped EV sales targets. Most rich nations are cutting climate finance to developing countries. Brazil's handling of the 2025 summit in Belém crystallised the dysfunction. The hosts took national emissions plans — the bedrock of Paris — off the negotiating table entirely, declaring them a matter for sovereign governments, not international talks. The result was a deal nobody loved and a deepening impasse heading into Cop31. Yet the case for abandoning the process is weaker than it appears. Clean energy deployment is accelerating outside the Cop framework. Pakistan's rooftop solar now supplies about a quarter of its electricity. Electric vehicles make up more than 40% of car sales in Vietnam. China's economic stake in decarbonisation — as the world's dominant manufacturer of solar panels and EVs — now gives Beijing a material reason to support the transition. A coalition of nearly 60 countries held an alternative meeting in Colombia in April 2025 and agreed to draw up national roadmaps for fossil fuel phase-out independently of Cop. The most promising concrete idea emerging for Cop31 is electrification targeting. Oxford's Jan Rosenow estimates that switching all final energy use to electricity could halve total global energy demand, because electric systems are fundamentally more efficient than combustion. A target of 35% of final energy from electricity by 2035, up from 23% today, would represent one of the first hard numbers the process has produced in years. The honest assessment is that Paris functions as what former Panama climate envoy Juan Carlos Monterrey calls a 'moral compass' — it set direction but not speed. The transformation it triggered in clean technology deployment is real and accelerating. But the treaty itself lacks any mechanism to force the pace that physics demands. Cutting methane by 40% alone could hold down temperatures by 0.3°C in the next decade. The question is whether the Cop process can evolve fast enough to produce binding commitments, or whether the real climate action will increasingly happen in side agreements, bilateral deals, and market forces operating around and despite the framework.
