Background: Exposure to asbestos fibres is known to cause asbestos-related diseases (ARDs) such as mesothelioma and lung cancer. The IHME Global Burden of Disease Study estimates over 233,000 people die from ARDs each year from historical exposure to asbestos. The WHO also estimates 70% of all work-related cancers are caused by exposure to asbestos.  Significant occupational exposure to asbestos continues to occur, particularly in low-and middle-income countries (LMICs) with reduced workplace protections. Also, there appears to be increasing numbers of ARDs caused by non-occupational exposure across all countries. The asbestos industry continues to market their product, particularly in WHO Western Pacific and South-East Asian region LMICs, areas that are also experiencing increased number and severity of climate change disaster events. Over 90% of global asbestos consumption is now concentrated in the WP and SEA regions.

Objectives: The aim of this study was to assess the impact of climate change on the future burden of asbestos-related disease in LMICs in the Western Pacific and South-East Asian regions.
 
Methods: The study involves a scoping review and secondary data analysis, focusing on published literature including peer-reviewed journal articles, national health databases, WHO and GBD datasets, and reports issued by governmental bodies responsible for occupational health and safety.
 
Results: Preliminary results identified several natural disaster events in WP and SEA regions which resulted in the uncontrolled release of asbestos. Climate change-related disaster events are likely to increase in number and severity. They are more likely to impact larger, poorer communities in congested areas, beyond traditional localised workplaces.
The continued production and use of asbestos in LMIC will result in greater amounts of asbestos-containing materials in the built environment at risk of destruction.
Conclusions/Implications: As climate change-related disaster events increase in number and severity, the need to impose national bans on production and use of asbestos-containing products in LMIC increases in urgency. Until this happens, improved control of exposures and increased awareness around the dangers posed by asbestos remain the primary goals.
