The Katoomba Group is an international working group composed of leading experts from forest and energy industries, research institutions, the financial world, and environmental NGOs, all dedicated to facilitating strategic partnerships that can launch green forest products in the marketplace. To accomplish this, the Katoomba Group must build collective understanding of how market-based instruments for environmental services are constructed and in which conditions in which they can work. The group met for the first time in Katoomba, Australia in1999. Forest Trends serves as the secretariat for this group and coordinates inter-sessional work.
