Bangladesh is experiencing the impact of climate change, which also exacerbates its existing vulnerabilities and jeopardizes socioeconomic growth. In response to climate change impacts, numerous climate funds have been established to aid with the nation's attempts to mitigation and adaptation actions. This paper set out to provide an in-depth overview and analysis of these funding sources, both internal, and external foreign funds that provide support in climate-relevant projects. It explores bilateral donations from nations like the US, EU, and Japan as well as multilateral programs like the GEF, Adaptation Fund, Climate Investment programs (CIFs), and Green Climate Fund (GCF). Moreover, domestic efforts such as the Bangladesh Climate Change Trust Fund (BCCTF) and national budget allocation for climate-relevant funds are examined. The analysis delves into various aspects including the scale and allocation of funding, in different sectors and identifies prioritized areas for funding. It analyzes experts’ opinions to identify barriers in existing financing mechanisms including accessing and utilizing climate finance using thematic analysis. Furthermore, the paper addresses issues of transparency, accountability, and governance pertaining to the distribution and utilization of climate finance while also identifying areas for improvement to ensure optimal use and fair distribution of funds.
