Foundations of the Energy-Environment Nexus and International Economic Law

Sherzod Shadikhodjaev

 

ABSTRACT: The intersection between energy and the environment is regulated on the basis of legal foundations that international economic law has developed on its own or ‘borrowed’ from (or otherwise relied on) such outside regimes as general international law and international environmental law. The borrowed principles, like sovereignty over natural resources or sustainable development, can find their reflection, directly or indirectly, in trade and investment agreements and case law and will continuously affect new developments in this field. Such foundations stemming from the external sources define the basic contours of State’s rights and duties associated with the energy–environment nexus. Apart from this, the international trading and investment systems provide self-created legal foundations for environmental policy space. They define the extent to which energy-related measures driven by environmental considerations can be accepted. The case of the Energy Charter Treaty is a striking example for demonstrating that the legal foundations are not static and may undergo important changes.
