This report examines the understanding, impacts, and lived experiences of climate change among informal workers in Shimla, Himachal Pradesh. Situated within a climate justice framework, the study recognises that climate change disproportionately affects socially and economically marginalised populations, particularly those engaged in informal work. In a fragile mountain urban context such as Shimla—characterised by ecological sensitivity, terrain constraints, and tourism-dependent livelihoods—these vulnerabilities are further intensified. The study seeks to document how informal workers perceive climate change, how it affects their livelihoods and living conditions, and how they cope with these changes in the absence of adequate institutional support.
