This blog reflects on the tensions and contradictions experienced at COP28 in Dubai, asking whether the conference marked a genuine turning point in climate ambition or largely reproduced patterns of greenwashing. Drawing on participant observation, the authors examine the contrast between official commitments to climate action and the host country’s resource-intensive development model, as well as the ambivalent messages conveyed through the conference’s imagery and discourse. The article situates the COP28 agreement within broader debates on fossil fuel phase-out, innovation, and planetary boundaries, and argues for transparent, evidence-based approaches to assess the credibility of climate commitments and rebuild trust in global climate governance.
