The chapter turns to consider two key implications of the environmental minimum for international environmental law. For one, there is considerable difficulty in applying the human rights-based framework of the book to issues surrounding transboundary environmental harm, particularly the overarching global issue of man-made climate change. Due to enduring difficulties establishing causality, as well as temporal, geographic concerns, and the at most lacklustre commitment of most states to upholding them as practical safeguards, human rights are unlikely to contribute decisively to the current policy debate. The environmental minimum and its human rights framework presuppose a robust commitment to human rights, environmental protection and the rule of law that is questionable at best with respect to many of the most notorious global polluters. The environmental minimum is more suited to specifying the scope, context, and relationship of competing environmental obligations, notably among the sustainable development goals, as well as provide a viable framework to enforce otherwise non-binding or underenforced treaty obligations under international environmental law.
