The Intergenerational Trust in Public Environnemental Law

The trust, who finds it's origin in the medieval English law, was used in private relations at the beginning, means that a trustee should conserve goods, without appropriate them, for a transmission to future beneficiary. To regards to the actual environmental crisis, the trust is particularly pertinent : different juridical mechanisms enter an intergenerational trust in which present generation should conserve natural resources for future generations, as the example of the Common heritage of mankind. This mechanism tries to establish a cohesive and an equity in the present generation and with the future one, and more generally, to enter a global solidarity, with all the difficulties involved.
