Yet at COP30 in Brazil last month, wealthy nations—responsible for four-fifths of historical emissions—resisted discussing their financial obligations while 1,600 fossil fuel lobbyists ensured the final agreement never mentioned the words “fossil fuel.” Professor Joyeeta Gupta at HTLS 2025 This failure reflects the persistent problem of climate action, and a deeper crisis of climate justice, according to University of Amsterdam professor Joyeeta Gupta, who has tracked climate negotiations for three decades. Speaking in an online session at the 23rd Hindustan Times Leadership Summit, Gupta rued that there is not enough attention to the rapidly shrinking emission headroom. “That’s one of the big problems—we are not taking this storyline that there is very little CO2 emission space left seriously”. Instead, nations are retreating into a “hegemonic response”: hoarding resources, refusing responsibility, and delaying action through “problematic narratives” like net zero and managed overshoot, she added in the session with Binayak Dasgupta.
