The EKO ECO blog exists to stimulate discussion on how to incorporate the value of ecosystem services into our economic system. It has been launched jointly by Ecosystem Marketplace and EKO Asset Management Partners, and presents the combined insights of a non-profit information provider and a for-profit asset management company.

We will be blogging about systems that encourage payment for environmental services, including the emerging carbon markets, water quality trading, payment for watershed services and species/wetland banking, among others. The blog is intended to complement the more in-depth articles and analysis that can be found in Ecosystem Marketplace with more rapid and up-to-date reflections on recent news, events, activities, and transactions. While the majority of our bloggers come from the staff of the Ecosystem Marketplace and EKO Asset Management Partners, we expect to have regular guest bloggers and writers. So stay tuned and feel free to share your thoughts with us.
