NGT Upholds Safety of Asbestos-Cement Roofing: No Evidence of Public Health Risk
Ministry of Environment, Forest and Climate Change to “Review the entire scientific evidence/material available and also review global best practices within 06 months and to take appropriate decision and make appropriate policies permitting
New Delhi, — In a major development for India’s building materials sector, the NGT after examining the submissions and experts committee views, the NGT declined to impose a blanket ban on asbestos-cement roofing sheets in schools and other education institutions. The Tribunal noted the absence of conclusive scientific evidence directly linking asbestos-cement sheets in buildings to adverse health impacts under normal use conditions.
The verdict in Dr. Raja Singh v. Union of India & Others (O.A. No. 298/2023) was issued after an extensive scientific evaluation by a multi-disciplinary Expert Committee constituted by the Ministry of Environment, Forest and Climate Change (MoEF&CC), pursuant to directions of the National Green Tribunal (NGT).
Experts Find No Evidence of Health Risk from Asbestos-Cement Sheets Under Normal Use
The expert committee found no data or evidence linking asbestos-cement roofing to health hazards in non-industrial settings such as schools and other education Institution. The Expert Committee observed that while:
“Asbestosis may be a problem in occupational exposure, there is no evidence to suggest that asbestos-cement sheets in normal use cause any harm.”
Experts also confirmed that airborne fiber levels under normal use are well below international safety limits, and that asbestos fibres are locked within the cement matrix, making the material stable, durable, and non-friable and that any potential risk can be minimised through safe handling during installation and removal.
NGT Favors Scientific Regulation Over Blanket Ban
The Tribunal observed that safe handling and adherence to BIS standards (IS 11769:1987 and IS 459:1992) ensure minimal exposure and environmental safety. It cautioned that unscientific bans could harm affordable infrastructure development, particularly in rural India, where asbestos-cement roofing provides cost-effective and climate-resilient shelter.
The NGT’s approach underscores the need for evidence-based policy and ongoing monitoring, rather than prohibition unsupported by data.
The Tribunal has directed the Ministry of Environment, Forest and Climate Change to “Review the entire scientific evidence/material available and also review global best practices within 06 months and to take appropriate decision and make appropriate policies permitting/minimizing use of asbestos cement roofing sheets and other asbestos contained material in schools, residential houses and other buildings, and proper management and disposal of asbestos waste in accordance with its vison statement with an action plan and appropriate time lines and “Issue detailed guidelines for the manufacture, installation, maintenance, dismantling, and disposal” of asbestos-containing materials to ensure environmental safety and protection of public health.
Industry Welcomes the Decision
The industry has welcomed the NGT’s ruling as a strong affirmation of science-based regulation, safety, and sustainable development.
It stated, “The judgment reaffirms decades of responsible manufacturing and effective regulatory oversight,” adding that “asbestos-cement sheets continue to be safe, durable, and vital to meeting India’s affordable housing and infrastructure needs.”
The industry further reaffirmed its commitment to high environmental standards, worker health and safety, and public awareness initiatives promoting the safe use, handling, and disposal of asbestos-cement products.
