the idea of launching ecosystem marketplace was borne out of meeting by members of the katoomba group, an international working group composed of leading experts from forest and energy industries, research institutions, the financial world, and environmental ngos dedicated to advancing markets for some of the ecosystem services provided by forests – such as watershed protection, biodiversity habitat, and carbon capture and storage. both ecosystem marketplace and the katoomba group are initiatives under forest trends. ecosystem marketplace specializes in market-based approaches to environmental protection—in the public and private spheres—regarding greenhouse gases, water, biodiversity, and conservation.
