Eternit opens asbestos-cement factory in Osasco, São Paulo — operates for 54 years without adequate worker protection until 1993
↗ SourceBrazil
Federal Supreme Court (STF) ruled November 29, 2017 (7-2 vote) that Federal Law 9.055/1995 permitting 'controlled use' of chrysotile was unconstitutional, establishing a full national ban on mining, processing, marketing, and distribution of chrysotile asbestos (ADI 3937, 3406, 3470). Ban reaffirmed February 23, 2023. Enforcement has been contested: Goiás state enacted a loophole law (No. 20,514/2019) allowing export-only mining, which SAMA/Eternit exploited until a five-year wind-down law (No. 22,935/2023) was enacted. ADI 6200 challenging the Goiás law was postponed indefinitely by the STF in October 2024.

The people who fought for change.
Fernanda Giannasi
ADVOCACY LEADER1983–presentLabour Inspector, Brazilian Ministry of Labor; co-founder of ABREA
Fernanda Giannasi is a Labour Inspector with Brazil's Ministry of Labor (since 1983) who became the central figure in the campaign for a national asbestos ban. She co-founded ABREA (Associação Brasileira dos Expostos ao Amianto) in 1995 with former Eternit factory workers and served as coordinator for Latin America of the Citizens' Virtual Network Against Asbestos. Giannasi documented hazardous conditions at the Osasco factory, led enforcement actions against the industry, and supported 3,500 workers in lawsuits. The industry responded with criminal defamation charges (from Eternit and Saint-Gobain), death threats, and a period of professional exile. Canada's government also pressured Brazilian officials against her enforcement work. She remained active through the 2017 STF ruling and the 2023 ban reaffirmation.

ABREA — Associação Brasileira dos Expostos ao Amianto
GLOBAL NETWORK1995–presentNational advocacy organization for asbestos victims, founded by Eternit factory workers, Osasco, São Paulo
ABREA was founded in 1995 by former workers of Eternit's Osasco factory after a generation of exposure with no protection. A 2003 ABREA survey of 1,022 former Eternit workers documented 24 deaths from asbestos-related disease, 223 respiratory disorder cases, 192 cases of pleural plaques, and 109 asbestosis cases. ABREA's documentation built the evidentiary base for Brazil's constitutional litigation and contributed directly to the STF decisions of 2017 and 2023. The organization continues to support sick workers and their families and to advocate for enforcement of the national ban.

Context and sources behind the numbers
All forms of asbestos have been banned since 2017. Buildings constructed before this date may still contain asbestos materials.
2.3 cases per million people per year. Mesothelioma is an aggressive cancer caused almost exclusively by asbestos exposure, with a latency period of 20–50 years.
A lower rate, though any mesothelioma cases indicate past asbestos exposure.

tens of millions of buildings with legacy asbestos-cement roofing
The period when asbestos was most heavily used in construction. Buildings from this era have the highest probability of containing asbestos materials.
