Climate action is strongly shaped by policies operating at local, national, and international levels, yet their effectiveness varies widely depending on political commitment, financing, and social inclusion. From the Global South perspective, Bangladesh’s climate policy framework stands out as one of the more effective national approaches. Instruments such as the Bangladesh Climate Change Strategy and Action Plan (BCCSAP) and the Bangladesh Climate Change Trust Fund (BCCTF) have helped translate climate risks into concrete action by prioritizing adaptation, mainstreaming climate considerations into development planning, and mobilizing domestic resources. A key factor behind their relative success is national ownership, which has reduced over-reliance on donors and allowed quicker responses to climate risks such as floods and cyclones. Strong political recognition of climate vulnerability has also helped keep climate change high on the policy agenda.
In contrast, several climate policies have struggled to deliver their intended outcomes. For example, while the Kyoto Protocol was groundbreaking in establishing legally binding emission targets, its effectiveness was limited because major emitters did not participate fully, especially during the second commitment period. Similarly, in many South Asian countries, including Pakistan, climate policies and disaster management plans often remain reactive and underfunded, with implementation gaps caused by weak coordination between federal and local institutions, short-term political priorities, and limited fiscal space. These barriers prevent policies from translating into sustained resilience on the ground.
At the international level, frameworks such as the Paris Agreement represent an important step forward due to their inclusive, bottom-up design and universal participation. However, they remain insufficient to meet global climate goals because Nationally Determined Contributions (NDCs) are largely voluntary, ambition levels are inadequate, and enforcement mechanisms are weak. Without stronger commitments on climate finance, loss and damage, and technology transfer, vulnerable countries in the Global South will continue to struggle to adapt at the scale required.
Political, economic, and social factors heavily influence climate policy outcomes. Politically, changes in leadership and governance quality affect continuity and commitment. Economically, limited resources constrain long-term investments in adaptation and mitigation, while socially, inequality and marginalization can exclude the most vulnerable groups from policy benefits. Where communities lack voice, even well-designed policies can fail.
Bangladesh’s experience offers several lessons for other Global South countries: prioritizing adaptation, establishing domestic climate finance mechanisms, and integrating climate action into national development planning can significantly improve policy effectiveness. However, the experience also shows that national action alone is not enough.
To bridge the policy–action gap, new approaches are needed. These include locally-led adaptation, stronger accountability mechanisms for international commitments, predictable climate finance, and better alignment between national policies and local implementation. Policies must move beyond ambition statements toward inclusive, adequately funded, and enforceable action if they are to match the urgency of the climate crisis.
