Rich nations in the global north owe 'climate debt' to poorer nations
More than a century of burning coal, oil and gas has fueled intense heatwaves, prolonged droughts, heavier rains and devastating floods. To prevent even more severe impacts, the U.N. global climate summit, Cop29, must deliver tangible results to keep global temperature rises below 36 degrees Fahrenheit, the limit defined in the 2015 Paris agreement. Achieving this goal means human societies can only emit a finite amount of additional carbon dioxide, known as the world’s “carbon budget.” Developed nations have exceeded their carbon budgets while developing countries remain within theirs. Carbon dioxide lingers in the atmosphere for centuries, turning past unchecked fossil fuel use into a costly planetary bill. Between 1870 and 2019, the U.S., E.U., Russia, U.K., Japan, Canada and Australia — home to just 15% of the global population — accounted for more than 60% of atmospheric carbon dioxide, according to the Delhi-based Centre for Science and Environment. This underscores the climate debt that rich nations in the global north owe to poorer nations. This reality — rather than oil and gas lobbying — should focus minds at Cop29 in Azerbaijan, where leaders must forge a new global climate finance plan by next week. Economists estimate that developing nations need $1 trillion annually by 2030, a figure that reflects the scale of the climate crisis. Yet there is little sign the rich world will contribute its fair share. A stronger, more unified approach is needed. Many of Africa’s environmental NGOs argue that the continent has been sidelined in global industrial shifts, particularly in green industrialization, due to its lack of a robust manufacturing base and its role as a raw materials supplier. While advanced economies dominate green innovation, Africa faces significant hurdles, including limited technology transfer, expensive financing and weak governance.
