The availability of natural resources depends on their nature. Renewable ones are accessible to both current and future generations, unlike non-renewable ones. Oil, coal and natural gas are an example of these exhaustible resources, with limited availability on our planet. When these resources are consumed, their availability decreases, causing poverty, inequality, and conflict. Thus, policymakers, in particu lar at the supranational level, have the task of promoting sustainable consumption practices that ensure equity between generations. To ensure well-being between gen erations and long-term sustainability of these resources, overconsumption of them must be penalized. With these premises, the decision maker must solve the problem of maximizing intergenerational utility.
