The voting rights associated with the ordinary shares are exercised by the STAK, which is the controlling body. The STAK represents the interests of the certificate shareholders and is established to distribute the stock certificate holders' profit. In addition, its task is to monitor the mission of greenSand and of its certificate holders. The stock certificates give right to dividend and are registered in the register of the STAK.
Eddy Wijnker has donated all his shares to the STAK, reasoning, "I want greenSand to fulfil its mission and to achieve the maximum return for our certificate holders. Everyone in the world benefits from cleaning up CO2. The social return is high and is shared with all stakeholders. We share the profit together." greenSand, the STAK and the certificate holders guarantee the mission. greenSand is accountable to its sole shareholder, the STAK. This is done by publishing the annual reports. The STAK is responsible for the certificate holders. Also, there is a conversation between greenSand and its certificate holders, and a joint effort is made to accomplish the mission.
