This brief provides insights for businesses on climate change, labour migration and human rights, drawing on a joint study by the International Organization for Migration (IOM) and the Stockholm Environment Institute. The study focused on migrant workers from Bangladesh and Indonesia employed on large palm oil plantations in Peninsular Malaysia, and on migrant workers from Cambodia and Myanmar employed on small-scale sugarcane plantations in Thailand’s border regions. The first part of the brief summarizes the main findings of the study; the second part provides recommendations specifically for businesses, guiding them on how they could contribute to climate resilience by promoting ethical recruitment and decent work for migrant workers impacted by climate change and environmental degradation
