WWF is working with partners around the world to restore nature by 2030 through our nine global practices: Wildlife, Oceans, Forests, Freshwater, Climate & Energy, Food, Finance, Governance and Markets. The practices bring together the combined efforts of our global network of national offices active in almost 100 countries.
Each of our practice leaders brings leadership and ambition to their roles, and a capacity and willingness to partner with others to bring about great change.
