Greenpeace International blog - Big Ag’s COP30 greenwashing: ‘Tropical Agriculture’ hides Amazon destruction Jehki Härkönen - 21 Nov 2025 I’m a campaigner with Greenpeace Nordic, working right now from the Brazilian city of Belem, at the mouth of the Amazon river. If, like me, you were waiting outside the COP30 climate talks this week, you might have seen someone holding a sign exposing what is really happening inside. The reality? Industrial agriculture is out in full force. From JBS, the world’s largest meat company, to pesticide giants like Bayer, global agribusiness is at COP30 to make you forget that food systems contribute around a third of global greenhouse gas emissions, and instead, convince you that it actually is a solution to global heating.
