Climate Change and Heat Stress: Impacts on Home-Based Workers and Street Vendors in Bangkok, Thailand

By , , , , , on October 21, 2025

Bangkok, Thailand, is among the cities most exposed to rising temperatures and the growing risks of climate change. With heat stress now a serious urban challenge, workers in informal employment, who make up 42% of the city’s workforce, are among the most affected. This policy brief examines how extreme heat impacts the livelihoods, health, and well-being of home-based workers, street vendors, and market traders in Bangkok, drawing on new research conducted by HomeNet Thailand (HNT) in partnership with WIEGO. The brief situates these findings within Thailand’s broader climate policy landscape, assessing the extent to which national and local climate plans address the vulnerabilities of workers in informal employment. This research is part of a broader project, Climate Justice and the Urban Informal Economy: Understanding Impacts and Strengthening Resilience, co-financed by Canada’s International Development Research Centre (IDRC).
