Bhutan & the Environment
Bhutan is the world's only carbon-negative country — constitutionally committed to environmental conservation as a pillar of Gross National Happiness. With 72% forest cover and over half its land formally protected, it stands apart from every other nation on earth.

Bhutan absorbs roughly 6.3 million tonnes of CO₂ per year while emitting only ~2.5Mt — making it the world's only carbon-negative country.
Bhutan's constitution mandates a minimum of 60% forest cover in perpetuity. Current cover exceeds that at ~72%, one of the highest in Asia.
Over half of Bhutan's territory is formally protected as national parks, wildlife sanctuaries, nature reserves, or biological corridors.
Bhutan generates nearly all its electricity from clean hydropower, and exports surplus power to India, earning foreign exchange while reducing regional carbon emissions.
The Constitutional Mandate
Article 5 of Bhutan's Constitution (2008) is arguably the most ambitious environmental clause in any national constitution. It mandates that:
- Every Bhutanese citizen is a trustee of the Kingdom's natural resources and environment
- The government shall ensure a minimum of 60% of Bhutan's land under forest cover for all time
- Conservation of biodiversity is a fundamental duty of state and citizens
- Environmental impact assessments are mandatory for all development projects
This is not aspirational language — it is legally binding. Governments have been held to it, and development proposals that would reduce forest cover below the constitutional threshold cannot proceed.
Carbon Negative Status
Bhutan absorbs approximately 6.3 million tonnes of CO₂ per year through its forests, while emitting only around 2.5 million tonnes — making it a net carbon sink. It is the only country in the world that can make this claim.
The country has committed to remaining carbon neutral for all time under the Paris Agreement, and it aims to never exceed 2.5Mt of annual emissions regardless of economic growth.
Why Does This Matter?
Bhutan's carbon negative status is made possible by its small population (~800K), high forest cover, and deliberate policy choices. It demonstrates that economic development and environmental protection can coexist — the central argument of Gross National Happiness.
Hydropower — Clean Energy Engine
Bhutan's rivers, fed by Himalayan snowmelt and monsoon rains, give it vast hydropower potential. The country generates nearly 100% of its electricity from hydropower and exports surplus power to India under long-term agreements. Revenue from hydropower exports is the single largest source of government income.
Total hydropower capacity is expected to reach 10,000 MW by 2030.
Glacial Lake Outburst Floods (GLOFs)
Climate change is accelerating glacial melt in Bhutan's highlands. Glacial lake outburst floods — sudden, catastrophic releases of water from glacial lakes — are an increasing risk for downstream communities and hydropower infrastructure. The National Center for Hydrology and Meteorology monitors over 2,600 glacial lakes.
Plastic Ban & Waste Policy
Bhutan has one of the world's strictest anti-plastic policies. Single-use plastic bags have been banned since 1999 — one of the earliest bans globally.
- Polystyrene (thermocol) foam food containers — banned
- Plastic bottles below 500ml — banned in many contexts
- All single-use plastics in protected areas and national parks
Tobacco Control
In 2004, Bhutan became the first country in the world to ban the sale of tobacco products. While personal consumption is technically permitted, public smoking is entirely prohibited. The Tobacco Control Act is strictly enforced.
Biological Corridors
Nine biological corridors connecting Bhutan's protected areas allow wildlife to move freely across the country's entire north-south gradient, from subtropical lowlands to alpine zones above 5,000 metres. Snow leopards, tigers, and elephants have all been recorded moving through multiple parks via these corridors.
National Parks & Wildlife Sanctuaries
Bhutan has 5 national parks, 4 wildlife sanctuaries, 1 nature reserve, and 9 biological corridors — covering 51.4% of its territory.
Jigme Dorji National Park
4,349 km²Northwest Bhutan
Bhutan's largest national park, spanning alpine meadows, glaciers, and subtropical forests. Home to snow leopards, takins, blue sheep, and over 300 bird species.
Royal Manas National Park
1,057 km²South Bhutan
A UNESCO World Heritage Site adjoining India's Manas Tiger Reserve. Exceptional biodiversity including Bengal tigers, Asian elephants, one-horned rhinos, and golden langurs.
Thrumshingla National Park
905 km²Central Bhutan
Connects eastern and western protected areas. Dense temperate forests with red pandas, clouded leopards, and the rare satyr tragopan.
Bumdeling Wildlife Sanctuary
1,545 km²Northeast Bhutan
Critical wintering habitat for the globally endangered black-necked crane. Also supports tigers and elephants along its lowland river valleys.
Jigme Singye Wangchuck National Park
1,730 km²Central Bhutan
Protects the Black Mountains range — a biodiversity corridor linking north and south. Contains rich subtropical and broadleaf forests.
Sakteng Wildlife Sanctuary
740 km²Far East Bhutan
One of the world's few protected areas specifically designated for the conservation of the yeti (migoi). Also protects red pandas, snow leopards, and the rare Sakteng orchid.
Phibsoo Wildlife Sanctuary
278 km²South Bhutan
Bhutan's only natural sal forest, sheltering chital deer, gaur, Asian elephants, and wild boar along the Indian border.
Khaling Wildlife Sanctuary
273 km²East Bhutan
Protects subtropical forests and is an important habitat for golden langurs — one of the world's most endangered primates — found only in Bhutan and adjacent India.
Key Species

| Red Panda | Endangered | Temperate bamboo forests | Unknown, declining |
| Black-Necked Crane | Vulnerable | High-altitude wetlands & valleys | ~700 winter in Bhutan |
| Takin | Vulnerable | Alpine meadows & forest edges | National animal of Bhutan |
| Golden Langur | Endangered | Subtropical forests | Only in Bhutan & NE India |
| Asian Elephant | Endangered | Southern subtropical plains | Small population in south |
| Greater One-Horned Rhino | Vulnerable | Manas floodplains | Rare, in Royal Manas NP |
Environment & Tourism
The Sustainable Development Fee (SDF) of USD 100 per visitor per night — paid by all international tourists — is explicitly tied to environmental conservation. A portion funds protected area management, anti-poaching patrols, and the forestry department.
Tour operators are required to follow Leave No Trace principles on trekking routes. Certain trekking areas are under quota to prevent overuse of fragile alpine ecosystems.
What Visitors Can Do
- Never litter — carry out all waste from trekking routes
- Do not buy wildlife products (feathers, pelts, horns, shells)
- Stay on designated trails in national parks
- Bring a reusable water bottle — tap water is safe in most towns
- Do not collect plants, flowers, or stones from protected areas
