The opening of the UN climate conference, COP29, was delayed as a dispute arose between developing and developed nations over the European Union’s carbon border tax, known as the Carbon Border Adjustment Mechanism (CBAM). Developing countries, including China and India, argued against adding "unilateral trade measures" like CBAM to the conference’s agenda, viewing it as potentially harmful to their economies. The delay underscores the tension between nations with differing climate agendas, with limited time available to agree on key issues like climate finance for developing nations.
