COP31開幕、気候変動枠組み条約事務局長が語る「COPの意義」

The 31st UN Climate Change Conference (COP31) opened in Antalya, Turkey, on November 9, 2026, amid public skepticism about its effectiveness, with the UN climate chief defending the process as vital despite slow progress. UNFCCC Executive Secretary Simon Stiell acknowledged that while climate impacts are accelerating, the Paris Agreement has shifted projected warming from 5°C to approximately 2.6°C, with renewable energy now cheaper than fossil fuels and clean energy investment reaching $2.1 trillion last year. Stiell admitted current national targets are insufficient, projecting only a 12% emissions cut by 2035 against the 60% needed for the 1.5°C goal, but noted the energy transition is irreversible and accelerating in Asia and Europe.
