In a groundbreaking legal move, Bangladesh has become the first South Asian country to challenge the legality of a Japan-backed fossil fuel-based power plan with the Supreme Court (SC), marking a historic step towards climate justice. A writ petition has been filed with the SC challenging the legality of the 'Integrated Energy and Power Master Plan (IEPMP) 2023' recently. The plan directly contradicts Bangladesh's Climate Prosperity Plan, and violates the Paris Declaration on Aid Effectiveness.
