This chapter explores existing literature on the climate–migration–peace nexus, examining the relationship between climate change and migration, as well as the link between migration and sustainable peace. The empirical results indicate that net migration and technological advancement are associated with lower levels of CO2 emissions, while sustained peace is associated with increased climate impact. Furthermore, increased migration positively contributes to long-term peace. These findings challenge conventional assumptions by presenting migration as a tool for climate mitigation and highlighting how prolonged peace can paradoxically lead to higher emissions. Policymakers are encouraged to harness these insights by promoting sustainable migration policies, investing in green technologies, and enforcing stricter environmental regulations in stable economies. Additionally, regional initiatives aimed at integrating economic migrants into job markets could reinforce the positive link between migration and peace.
