The Forest Enterprise

The Forest Enterprise Foundation is established with the aim to contribute to the conservation of ecosystems by developing and promoting models that value the crucial services that ecosystems provide to mankind.

Until recently Denis was Managing Director at Climate Neutral Group, a leading carbon offset company. Denis combines policy making skills with international field experience and has initiated The Forest Enterprise Foundation in order to create worldwide awareness and commitment on the value of ecosystems and ecosystem services.
