Takeaways

• Bangladesh’s financial institutions, particularly the banking sector, have become crucial drivers of climate mitigation financing, collectively disbursing more than BDT 700 billion between 2021 and 2024.
• This pivotal shift is being guided by the central bank’s 2023 Sustainable Finance Policy, which integrates environmental, social, and governance (ESG) factors into lending decisions.
• To fully fund the nation's ambitious green transition goals, including the NDC targets, banks require stronger regulatory incentives and specialized capacity building.

As one of the world's most climate-vulnerable nations, Bangladesh faces existential threats from rising sea levels, cyclones, and erratic rainfall. Amid these daunting realities, a powerful domestic force, the country's banking sector, has quietly stepped up to back its climate ambitions. Once confined to conventional lending, banks are now transforming into vehicles for sustainability, playing an increasingly pivotal role in driving climate mitigation financing.

The stakes are high. Bangladesh’s climate roadmap, anchored in its Nationally Determined Contributions (NDC), pledges to cut greenhouse gas emissions by up to 13.9 per cent by 2035. Achieving this will require staggering investments, potentially reaching USD 270.13 billion if external financing can be secured. While international support exists, domestic capital mobilization is deemed critical to close this substantial funding gap and finance the national green transition.

Banking on Climate Action

The answer to this domestic financing challenge is increasingly found within the financial system. Between 2021 and 2024, the banks in Bangladesh collectively disbursed over BDT 700 billion (70,000 crore) in climate mitigation financing, a remarkable feat for the private sector.

A major catalyst for this change was the central bank's Sustainable Finance Policy, launched in 2023. This policy requires banks and financial institutions to incorporate environmental, social, and governance (ESG) considerations into their credit assessments. This shift has incentivized banks to actively promote sustainability through green lending and environmentally responsible investments, aligning their portfolios with the national NDC and the broader Paris climate agenda.

Why the Banking Sector Leads

The banking sector is uniquely positioned to lead this climate transition due to several structural advantages. Firstly, banks command a significant share of national savings, enabling them to mobilize vast pools of domestic capital and channel it toward low-carbon investments like renewable energy and energy efficiency.

Secondly, banks possess the expertise to manage the new layers of financial risk introduced by climate change, from physical damage to transition risks as industries decarbonize. The central bank's policy framework further supports this, encouraging innovation in financial products. New offerings, such as concessional green loans, climate risk insurance, and sustainability-linked bonds, are attracting investors eager to support climate-smart projects. Crucially, the banking sector acts as a bridge, connecting investors with the private sector, which is the largest untapped source of climate action funding.

Closing the Financing Gaps

Despite the promising progress, the banking sector must overcome several challenges to fully unleash its potential. The current framework needs strengthening with more incentives, such as tax rebates for green investments and simplified guidelines for issuing green and sustainability-linked bonds.

Furthermore, building institutional capacity is essential. Financing complex climate projects requires specialized knowledge of environmental risks and renewable technologies. Banks need dedicated teams trained in assessing both physical and transition risks. Finally, enhancing transparency through robust reporting frameworks aligned with international best practices is key to attracting international investors and preventing greenwashing.
