In a landmark move underscoring its frontline role in the global fight against climate change, the Government of the People’s Republic of Bangladesh has released its Third Nationally Determined Contribution (NDC 3.0), pledging significant cuts to greenhouse gas emissions while amplifying calls for international support to shield its vulnerable population from escalating environmental threats.

The 50-page draft final report, unveiled this month, charts a course for emission reductions by 2035 that aligns with the Paris Agreement’s imperatives, emphasizing a just transition to low-carbon development. Despite contributing less than 0.5% of global emissions, Bangladesh faces disproportionate risks from sea-level rise, cyclones, and river erosion—hazards that could displace millions and upend its economy.

A Nation on the Brink: Contextualizing Bangladesh’s Climate Pledge

Bangladesh’s journey toward climate resilience is etched in its geography and history. Nestled in the Ganges-Brahmaputra Delta, the country is a hotspot for extreme weather, with floods, droughts, and tropical cyclones claiming lives and livelihoods annually. Over the past two decades, socio-economic progress has been remarkable: GDP growth averaging 6-7% yearly, poverty reduction from 44% in 2000 to under 20% today, and strides in food security and urbanization. Yet, these gains are fragile. The NDC report highlights how climate impacts exacerbate inequalities, particularly for women, youth, and marginalized communities in rural and coastal areas.

The document traces Bangladesh’s proactive climate integration back to the 2009 Bangladesh Climate Change Strategy and Action Plan (BCCSAP), followed by the 2010 Delta Plan 2100 and the 2022 Bangladesh Delta Plan 2100 (BDP2100). Its first NDC in 2015 set an unconditional 5% reduction target by 2030 (14 Mt CO2eq), rising to 15% with international support. The updated 2021 NDC amplified this to 15% unconditional and 37% conditional, focusing on energy efficiency and renewables.

NDC 3.0 builds on this legacy, embedding climate action into Sustainable Development Goals (SDGs), especially SDG 13 (climate action) and SDG 7 (affordable and clean energy). It positions low-carbon growth as an opportunity for job creation, gender equity, and resilient infrastructure. “By 2035, we’re not just mitigating emissions—we’re unlocking green jobs, empowering women in renewable sectors, and fortifying our delta against the sea,” the report states, reflecting a holistic vision that intertwines mitigation with adaptation and loss-and-damage provisions.

Emission Projections: From Business-as-Usual to Ambitious Cuts

At the heart of NDC 3.0 are quantifiable targets for 2035, benchmarked against a 2022 base year where total GHG emissions reached 252.03 million tonnes of CO2 equivalent (Mt CO2eq). Under a Business-as-Usual (BAU) scenario—projecting unchecked growth in energy demand, industrialization, and population—the figure balloons to 418.40 Mt CO2eq by 2035, a 66% surge driven by fossil fuels and urban expansion.

Bangladesh’s unconditional pathway charts a 6.4% reduction from BAU, capping emissions at 391.66 Mt CO2eq. With conditional support, this deepens to a 20.1% cut, reaching 334.42 Mt CO2eq—a trajectory that could limit global warming to 1.5°C if replicated globally. The report breaks this down by sector:

Energy dominates at 63.7% of BAU emissions, followed by waste (17.3%), AFOLU (12.8%), and Industrial Processes and Product Use (IPPU) (6.1%). The projections incorporate sector-specific models, drawing from renewable energy policies and waste surveys, ensuring realism amid Bangladesh’s 8% annual energy demand growth.

Figure 1 in the report visualizes these arcs: a steep BAU climb from 2022’s 252 Mt, tempered by unconditional moderation and a sharper conditional plunge—underscoring the leverage of external aid.

Mitigation in Action: Sectoral Strategies for a Greener Future

NDC 3.0’s mitigation blueprint spans energy, agriculture, industry, transport, and waste, prioritizing renewables, efficiency, and circular economies. The energy sector, responsible for over half of emissions, targets a 28.57% reduction under conditional measures through an expansive renewable portfolio.

Key actions include:

• Power Generation: Scaling renewables to 25% of the electricity mix by 2035 (11,200 MW unconditional; 14,600 MW conditional), with solar rooftop parks (2,400 MW unconditional; 4,800 MW conditional), irrigation solar (1,000 MW), and biogas/wind (1,000 MW).
• Transport: Electrifying 30% of public passenger vehicles and deploying 348 km of railway routes with solar-equipped stations, slashing fuel-based emissions by 8.95%.
• Industry and Buildings: Converting 40% of clay bricks to non-fired blocks, achieving 19.2% energy efficiency gains in manufacturing (7.4 Mt CO2eq reduction), and promoting rooftop solar in 50% of new industrial buildings.
• Agriculture and Forestry: Enhancing solar irrigation (45,000 pumps unconditional) and clean cooking (30% LPG/modern fuels), while sustainable land management curbs AFOLU emissions by 11.36 Mt CO2eq conditionally.

Waste management focuses on reducing open dumping and incineration, targeting a 9.80 Mt CO2eq cut through improved treatment. Cross-sectoral enablers like skills development and financial support amplify these efforts, with policies ensuring regulatory coherence.

The report’s contribution to the first Global Stocktake (GST) is profound: Bangladesh’s pathways align with 1.5°C goals, targeting 19.2% total power generation from renewables and phasing out 90% of inefficient coal by 2040. “This is our equitable share—deep, fair, and urgent,” the document asserts, calling for GST recognition of developing nations’ adaptation burdens.

Beyond Mitigation: Adaptation, Equity, and the Human Dimension

Mitigation alone won’t suffice in a delta drowning in vulnerability. NDC 3.0 dedicates chapters to adaptation and loss-and-damage, prioritizing disaster management, urban greening, and ecosystem restoration. It advocates for enhanced transparency frameworks (ETF) to track progress, drawing lessons from Bangladesh’s innovative data practices for other nations.

Cross-cutting themes weave equity throughout: Gender, Disability, and Social Inclusion (GESI) measures ensure women’s leadership in green jobs; human rights protections safeguard indigenous voices; and youth participation fosters intergenerational justice. “Climate action must be inclusive, or it fails the most vulnerable,” notes a section on ensuring fair transitions.

Implementation hinges on scaled-up support: $100 billion annually in climate finance, technology transfers, and capacity building. The report outlines investment needs assessments, carbon market strategies, and governance arrangements, including a National GHG Inventory and Mitigation Registry System (MRV).

A Call to the World: Unlocking Bangladesh’s Potential

As COP30 looms in Brazil, Bangladesh’s NDC 3.0 arrives as both a beacon and a plea. It demonstrates how a low-emitter can lead with ambition—reducing emissions by 20% conditionally while advancing SDGs—yet stresses that realization demands predictable flows from the Global Stocktake’s GST1 Outcome.

“With strong national leadership and international collaboration, we can turn climate threats into opportunities for sustainable prosperity,” the report concludes. For a nation where 160 million souls defy the tides, this pledge is more than policy—it’s a testament to resilience, urging the world to match its resolve.
