The OAS supports member states in the design and implementation of policies, and projects to integrate environmental priorities into poverty alleviation and socio-economic development goals. Actions are implemented at the hemispheric level, facilitating international meetings and conferences on key issues of sustainable development, as well as “on-the-ground” activities. The Organization carries out several mandates designed to protect biodiversity, strengthen environmental law, manage water resources, raise awareness on climate change, and promote sustainability, among others.
