World Bank studies project Bangladesh's GDP growth could fall by 2–3% by 2050 if climate adaptation is delayed. A separate analysis by Ember and the Climate Vulnerable Forum finds Bangladesh could leapfrog the fossil fuel pathway entirely — using solar, battery storage, and electrification to achieve faster, cheaper, and more secure growth than the conventional energy model. These two reports read together define the choice Bangladesh faces right now: pay for the transition or pay for the consequences.
