Gustavo Petro opened a 57-country climate summit with a stark warning: a fossil-fueled model of capitalism now threatens to pull the world toward war, fascism and even extinction.

The Colombian president, speaking to governments gathered to discuss a green energy transition, argued that the danger does not come from climate change alone but from the political and economic forces that profit from delay. He cast fossil fuel interests as entrenched powers fighting to preserve an energy system he described as archaic and lethal. In Petro’s framing, the climate crisis has become a test of whether the global economy can break with the industries that built it.

“The question that needs to be asked is whether capitalism can truly adapt to a non-fossil energy model.”

Petro’s remarks pushed far beyond the usual summit language of targets and timetables. He linked the fossil fuel economy to a broader crisis of democracy and stability, warning that the pressures created by this model could fuel conflict and authoritarian politics. Reports indicate he told delegates that the inertia of fossil-based power runs so deep that it risks dragging humanity and other life down with it rather than yielding to change.

Key Facts

  • Colombia’s president Gustavo Petro addressed a 57-country summit on green energy transition.
  • He described the current fossil-fueled model of capitalism as “suicidal.”
  • Petro warned that fossil fuel interests could block transition efforts and endanger humanity.
  • His speech tied the climate crisis to war, fascism and the future of the global economy.

The intervention lands at a moment when governments face rising pressure to balance energy security, economic growth and climate commitments. Petro rejected any easy compromise, suggesting that the real obstacle lies in the power of industries with the most to lose from decarbonization. His comments also underscore a widening divide in climate politics: whether leaders still see the transition as a technical adjustment or as a direct confrontation with the structure of today’s economy.

What happens next will matter far beyond this summit. If more governments adopt Petro’s harder line, climate diplomacy could shift from cautious consensus to an open political fight over fossil power, investment and state priorities. If they do not, his warning will hang over future talks: delay no longer looks like drift, but like a decision with historic consequences.
