Climate finance in Bangladesh encompasses capital flows mobilized by state agencies and public and private financial institutions to mitigate the effects of climate change and promote adaptation in strategic sectors such as energy, agriculture, and transportation. In 2023, the country saw a 3.64% increase in clean energy investment, reaching US$333.89 million—a figure still far from the estimated US$1.5 to US$1.7 billion annually required to meet its target of 40% renewable electricity by 2041. Domestically, approximately 17.4% of the country's territory, or 2.58 million hectares, is covered by forests, while soil degradation and salinization affect nearly half of agricultural land, reinforcing the urgency of investing in adaptation.
Domestically, the country's green banking framework dates back to 2011, when the Bangladesh Bank required all financial institutions to establish dedicated green finance units. The Sustainable and Renewable Energy Development Authority (SREDA) coordinates policies such as the Renewable Energy Policy (2008), the Energy Efficiency Master Plan (2016), and Net Metering (2018), which have already enabled over 218 MW of rural solar systems and 26 microgrids by 2014. Recent initiatives, such as the Mujib Climate Prosperity Plan and the Grand Railway Plan 2022, project to mobilize up to US$30 billion per year by 2030 to modernize infrastructure and promote the energy transition.
Externally, Bangladesh relies on contributions from multilateral partners and foreign investors. Notable among these is the $430 million solar project with ACWA Power and the use of funds such as the Global Environment Facility - Least Development Countries Fund (GEF-LDCF) and the Green Climate Fund. Furthermore, advances in Islamic finance —via Green Sukuk —and the National Adaptation Plan ($610 million raised by 2023) expand sources of capital.
Still, experts point to imbalances: more than 50% of Bangladesh Climate Change Trust Fund ( BCCTF) resources went to physical infrastructure, while less than 1% financed integrated disaster management, and rising external debt (38% of GDP) raises concerns about fiscal sustainability. Despite this, the country has exceptional solar (up to 240,000 MW) and wind (up to 150,000 MW) potential and is advancing reforms to diversify financing mechanisms and strengthen green governance.
Climate context and vulnerabilities
Climatic and forestry context
Bangladesh's total land area is approximately 14.76 million hectares, of which about 2.58 million hectares—or 17.4% of the territory—is covered by forests, including plantations. However, land degradation represents one of the country's major environmental challenges, affecting more than 2 million hectares—approximately 40% of the country's land mass—due to factors such as topsoil erosion, nutrient depletion, acidification, and riverbank collapse. Salinization in coastal regions increased from 0.83 million hectares in 1973 to 1.05 million hectares in 2009, and currently impacts more than 53% of the country's coastal areas.
Economic and social context
In August 2024, the abrupt replacement of the government in Bangladesh jeopardized the advancement of renewable energy by canceling or renegotiating strategic agreements, generating strong uncertainty among investors. Under the leadership of Muhammad Yunus, the interim government has been reviewing energy policy to restore market confidence and accelerate the transition to clean energy. Although the renewable sector recorded unprecedented growth in 2024, continued success now depends on the viability of new projects ready to attract investment in 2025–2026.
Agriculture is a key pillar of Bangladesh's economy, employing 40% of the workforce and contributing 12.5% of GDP. However, the sector faces significant threats from climate change. Projections indicate that by the 2050s, average temperatures will rise by 1.6 °C and annual rainfall will increase by 4%, increasing the incidence of floods, cyclones, and droughts—all of which jeopardize agricultural productivity and soil stability.
Bangladesh's transportation sector, vital to the country's economic growth and connectivity, is increasingly vulnerable to climate-related hazards such as floods, cyclones, coastal erosion, and heat damage—threats that affect roads, railways, bridges, and inland waterways. Rural transportation networks are especially exposed, suffering from landslides, recurrent flooding, and structural weakening caused by extreme weather events and sea-level rise —factors that compromise connectivity and significantly increase maintenance costs.
Energy context
Bangladesh's energy supply is dominated by natural gas and petroleum, which together account for about 80% of the total energy supply, while clean renewable sources contribute less than 1%. Solar power leads the renewable sector with approximately 946 MW of installed capacity, and hydropower with 230 MW. Biofuels and waste, including biogas, biodiesel, and ethanol, currently constitute the third-largest segment, contributing approximately 15.5% of the energy mix.
Despite significant progress in expanding electricity generation and energy access, Bangladesh faces challenges due to its heavy dependence on declining natural gas reserves and imported fuels, which poses risks to long-term energy security and economic stability.
In 2023, the average electricity price in Bangladesh was approximately US$0.083 per kWh—lower than the global average of US$0.161 per kWh and very close to the Asian average of US$0.082 per kWh.
Bangladesh's national power grid has an installed capacity of 25,100.1 MW, significantly exceeding the country's peak demand of around 15,648 MW. This overcapacity contributes to annual financial losses estimated at around US$1.2 billion. The integration of smart grid technologies and decentralized renewable sources, such as microgrids, is seen as a promising strategy to increase grid resilience, support rural electrification, and encourage the transition from captive generation to grid supply.
Legal and institutional frameworks Bangladesh has set ambitious renewable energy targets, aiming for 10% to 15% of its electricity to come from renewable sources by 2030 and 40% by 2041, in line with its sustainable development and climate change commitments. Reaching the 40% target will require an estimated annual investment of between $1.53 billion and $1.71 billion from 2024 to 2041, not including additional costs for grid modernization and energy storage infrastructure.
The Sustainable and Renewable Energy Development Authority (SREDA) is the central agency responsible for implementing renewable energy policies in Bangladesh, supporting initiatives such as the Renewable Energy Policy (2008), the Energy Efficiency Master Plan (2016), and the Net Metering Guideline (2018). These policies aim to achieve 10% electricity from renewable sources by 2041, while enabling, through the energy compensation system (Net Metering), consumers to sell up to 70% of the energy generated by their rooftop solar systems back to the grid.
The draft of the 2025 Renewable Energy Policy proposed new incentives, including an exemption from import tariffs for renewable energy-related materials, a 10-year corporate income tax exemption for new projects, a transaction tax exemption, and commitments to the development of battery storage systems.
The Mujib Climate Prosperity Plan, along with the Grand Railway Plan 2022, outlines a 30-year vision to modernize Bangladesh's railway infrastructure, incorporating weather-resistant designs, electrification, and energy-efficient trains. In parallel, it also aims to transform the transportation sector as a whole by promoting the adoption of electric vehicles, electric buses, electric river transport, and mass transit systems, with the aim of reducing emissions and alleviating urban congestion. To enable these transitions, the plan seeks to mobilize up to $30 billion per year by 2030 through domestic and international financing sources.
The 2021 Automotive Industry Development Policy further boosts the adoption of electric vehicles in Bangladesh by offering tax exemptions, import duty exemptions for EV components, and support for battery recycling and charging infrastructure. These measures create a favorable environment for local manufacturing and strengthening supply chains, as demonstrated by the upcoming production of 1 GWh of lithium-ion batteries by Bangladesh Lithium Battery Ltd.
The Bangladesh Investment Development Authority (BIDA) plays a central role in facilitating foreign direct investment, offering a variety of incentives specifically designed to attract investors to sustainability-focused sectors. Key benefits include broad tax breaks—up to 100% for up to 10 years for public-private partnerships —tax-free profit repatriation, and reduced corporate income tax rates for sustainable industries, such as the 10% rate for LEED-certified textile mills and specific incentives for plastic recycling plants.
Special Economic Zones (SEZs) in Bangladesh, administered by the Bangladesh Economic Zones Authority (BEZA), offer significant incentives such as tax exemptions, duty-free imports of capital machinery, and simplified granting of business licenses, with the aim of attracting both domestic and foreign investment.
Bangladesh has been making rapid progress in adopting global climate disclosure and ESG reporting standards. The Bangladesh Stock Exchange now requires companies to include ESG information in their annual reports, and compliance with this requirement increased by 36% between 2018 and 2019—a clear sign of growing corporate engagement with sustainable practices.
The Bangladesh Bank introduced comprehensive green finance guidelines in 2011, aiming to promote sustainability in the country's financial sector. Key guidelines included the development and approval by bank boards of directors of a green finance policy, as well as the establishment of a Green Banking Unit (GBU) within each financial institution to oversee the implementation and enforcement of these guidelines. Sustainable manufacturing
Bangladesh has established itself as a global leader in sustainable manufacturing, particularly in the apparel sector, with over 100 LEED- certified factories by 2021—a result of robust government policies, public-private partnerships, technological innovation, and corporate initiatives aligned with environmental and social governance (ESG) principles. Government incentives, such as special tax rates for LEED-certified textile factories and corporate tax breaks for plastic recycling plants, have played a key role in this progress. International buyers have also been putting pressure on apparel manufacturers to adopt environmentally responsible practices, which has further driven the green transition in the sector. Public funding Bangladesh has been placing increasing priority on integrating renewable energy sources into its national electricity grid through several major initiatives, such as mandatory net metering for all utilities, a government-run rural rooftop solar program, and the development of solar microgrids.
Net metering allows residential, commercial, and industrial consumers to sell surplus electricity to the grid, with tariffs set by the Bangladesh Energy Regulatory Commission, encouraging the adoption of distributed solar systems. The rural rooftop solar program, launched in 2003 with an investment of $696 million, provided 218 MW of electricity to 18 million people, contributing significantly to improved rural electrification. Furthermore, by 2014, 26 solar microgrids with a total capacity of 5 MW provided electricity access to approximately 16,000 rural residents and reduced CO₂ emissions by 29,300 tons over their lifetime.
