Environment & Sustainability Guide in Bangladesh

Air quality, green spaces, and environmental policies

Bangladesh faces severe environmental challenges due to its low-lying geography and dense population of 164 million. Climate change drives rising temperatures, intensified floods, and sea level rise threatening 20% of land by 2050. Air quality remains stable but urban pollution persists. Water contamination and natural disasters like cyclones pose ongoing risks, while policies target renewables and disaster resilience.

Air Quality Index

0510

Moderate

5.5/10(AQI: N/A)

Stable trend

Air quality in Bangladesh shows stable trends over the past 6 months per database data. Dhaka often exceeds WHO PM2.5 guidelines with brick kilns and vehicles as main sources. Government initiatives like the Clean Air Act aim to reduce emissions but enforcement challenges persist in urban areas.

Water Quality

0510

Poor

4.5/10

Water quality in Bangladesh is poor with arsenic contamination affecting 20 million people and surface water polluted by industrial effluents and untreated sewage. Only 47% have access to safely managed drinking water. Government monitoring through DPHE exists but treatment coverage remains inadequate.

Arsenic exceeds WHO limits in 56% of tubewells; urban areas face fecal contamination risks.

Recycling System

Recycling infrastructure in Bangladesh is underdeveloped with no national rate data available from database. Informal waste pickers handle most recyclables like plastic and metal in urban areas. Formal systems limited to Dhaka; government pushes extended producer responsibility but coverage <5%.

Recycling Rate: —%

Green Spaces

Forest coverage stands at 11.1% with protected areas covering 1.4 million hectares including Sundarbans mangrove forest. 24 national parks and 8 wildlife sanctuaries protected but deforestation from agriculture averages 26,000 ha/year lost 2010-2020.

Forest Coverage: 11.1%

National Parks: 24

Sundarbans Reserved Forest (UNESCO site) covers 10,000 km²; Bhitarkanika National Park protects mangroves and crocodiles.

Environmental Policies

Bangladesh follows Paris Agreement with NDC targeting 5% unconditional GHG reduction by 2030. Environment Conservation Act 1995 regulates pollution. Plastic ban on thin bags since 2002; renewable targets aim for 10% energy by 2020 (missed).

Key Policies:

•Environment Conservation Act 1995
•Bangladesh Delta Plan 2100
•Plastic Bag Ban 2002

Renewable Energy: Revised NDC: 15% renewables by 2030; solar home systems reached 6 million installations.

Natural Disaster Risk

HIGH

Bangladesh ranks among top 10 disaster-prone countries with floods, cyclones, and river erosion affecting millions annually. Cyclone preparedness reduced fatalities from 300,000 (1970) to <100 (2020s).

Climate Change Impacts: Temperatures rose 0.55°C/decade 1985-2020; extreme rain days increased 20%; cyclones intensified 10-20% since 1970s. Sea levels rose 3.8mm/year 2000-2020 threatening 17% land by 2050. Floods affected 42 million (2022); Cyclone Amphan (2020) killed 26, $13B damage.

Sustainability Initiatives

Renewable Energy

Solar Home Systems program installed 6 million units powering 14 million people by 2021. National Solar Energy Roadmap targets 2.4 GW by 2041.

Disaster Resilience

Cyclone Preparedness Program with 76,000 volunteers saved 1 million lives since 1965. Early warning reaches 90% coastal population.

Climate Adaptation

Bangladesh Delta Plan 2100 integrates water management, agriculture resilience; polders protect 40% coastal areas.
