Environment & Sustainability Guide

Air quality, green spaces, and environmental policies in Bhutan

Bhutan maintains one of Asia's most pristine environments, with over 70% forest cover and a carbon-negative status achieved through strong forestry and hydropower reliance. Climate change poses challenges including glacier retreat, GLOFs, and extreme weather like floods, yet the nation leads in sustainability via Gross National Happiness integration and international commitments. Air quality is generally good with stable trends, though household pollution contributes to health impacts.

Air Quality Index

Good

8.0/10(AQI: 27)

Stable trend

Bhutan's air quality is excellent regionally, with population-weighted PM2.5 at 27.87 µg/m³ in 2019. Ambient PM2.5 caused ~25 deaths per 100,000 in 2021, mainly from households (residential biomass), industry, dust, and agriculture. Trend stable per database; clean air preserved by forests and hydro power.

Water Quality

Excellent

9.0/10

Bhutan's water is pristine due to minimal industrialization and extensive forests. Vulnerabilities include climate-driven sedimentation, erosion, and flow variations affecting quality for drinking, irrigation, and hydropower. High access to basic sanitation at 77.94% in 2022 supports safety.

Clean rivers and springs provide safe drinking water; government monitors via National Environment Commission.

Recycling System

Bhutan manages waste through national strategies; waste emissions are 5% of GHGs (2020), doubling 2000-2019, mainly methane from wastewater. Recycling infrastructure developing amid hydropower focus; no specific rate available.

Green Spaces

Bhutan mandates 60% forest cover constitutionally, currently ~70%, providing carbon sinks exceeding emissions for carbon-negative status. Primary forests support biodiversity and rural livelihoods.

Forest Coverage: 70.0%

National Parks: 10

Extensive national parks and reserves cover much of the country, preserving Himalayan ecosystems.

Environmental Policies

Bhutan remains carbon-negative, compliant with NDC via LULUCF sinks (-7.8 MtCO2e by 2030). Policies emphasize hydropower, forest conservation, and GNH. Leads GZero forum for net-zero advocacy.

Key Policies:

•Carbon Neutrality NDC
•60% Forest Cover Mandate
•Paris Agreement Compliance

Renewable Energy: Hydropower dominant; modest 20 MW non-hydro target by 2025 (9 MW achieved).

Natural Disaster Risk

MODERATE

Bhutan faces floods, landslides, GLOFs, earthquakes in Himalayan terrain. Recent events include devastating floods causing losses.

Climate Change Impacts: Rising temperatures cause glacier retreat at 30-60m/decade, forming supra-glacial lakes nearing GLOF thresholds. Extreme events like 2022 heatwaves/floods intensify; increased precipitation variability, sedimentation. Projections: emissions rise to 2.9-3.0 MtCO2e by 2030 but sinks maintain neutrality short-term; long-term risk if unchecked.

Sustainability Initiatives

Renewable Energy

Hydropower provides bulk of energy; carbon-negative via forests absorbing more GHGs than emitted. Non-hydro renewables at 9 MW toward 20 MW 2025 target.

Waste Management

Waste emissions 5% of GHGs; focus on wastewater methane. Environmental accounts track progress annually.

Climate Action

GZero forum and SDG13 priority; VNR 2025 highlights carbon-negative leadership.
