The Reports section of this website has a new report on constitutional treatment of the environment--look under the "Special Issue Domains" menu under the Reports tab. Constitutional treatment of the environment is a relatively recent phenomenon, but is now found in some 66% of texts. Some constitutions provide for a duty of the state to protect the environment or specific natural resources, while others frame the issue in terms of a right to enjoyment of the environment. See the full report for more details!
