Our point of analytical departure is that the state of the global environment is deteriorating despite the accumulating body of international environmental law. By drawing on the recent Earth system science concept of interlinked planetary boundaries, this article makes a case for a goal-oriented, purposive system of multilateral environmental agreements. The notion of ‘goal’ is used here to mean a single, legally binding, superior norm – a grundnorm – that gives all international regimes and organizations a shared purpose to which their specific objectives must contribute. A bird’s eye view of the international environmental law system reveals how the absence of a unifying goal has created a condition that is conducive to environmental problem shifting rather than problem solving. We argue that a clearly agreed goal would provide the legal system with a point of reference for legal reasoning and interpretation, thereby enhancing institutional coherence across Earth’s subsystems. To this end, this article concludes by observing that the protection of the integrity of Earth’s life-support system has emerged as a common denominator among international environmental law instruments. Accordingly, we suggest that this notion is a strong candidate for the overarching goal of international environmental law.

38 In his comprehensive analysis of legal reasoning in the context of international and domestic environmental law, Douglas Fisher concludes that ‘the point of commencement’ is the most important issue of any process of legal reasoning. Once this has been determined, the process of reasoning will assume the form that the point of commencement dictates: see Fisher, D.E., Legal Reasoning in Environmental Law: A Study of Structure, Form and Language (Edward Elgar, 2013), at p. 456. Crucially, the absence of an environmental grundnorm creates a vacuum that is currently filled with utilitarian, state-centred and other traditional considerations that can be perceived as in themselves reflecting a certain grundnorm or ‘core adjudicatory norm’: Bosselmann, n. 32 above, at p. 67.

110 ‘“Forest” is a minimum area of land of 0.05–1.0 hectares with tree crown cover (or equivalent stocking level) of more than 10–30 per cent with trees with the potential to reach a minimum height of 2–5 metres at maturity in situ. A forest may consist either of closed forest formations where trees of various storeys and undergrowth cover a high proportion of the ground or open forest. Young natural stands and all plantations which have yet to reach a crown density of 10–30 per cent or tree height of 2–5 metres are included under forest, as are areas normally forming part of the forest area which are temporarily unstocked as a result of human intervention such as harvesting or natural causes but which are expected to revert to forest’: Report of the Conference of the Parties on its Seventh Session, held at Marrakesh from 29 October to 10 November 2001, Addendum, Part Two: Action Taken by the Conference of the Parties, Vol. I, UN Doc.

125 Ocean iron fertilization could, in theory, reduce the rate of increase of atmospheric carbon dioxide, and hence the rate of ocean acidification in the upper ocean. However, if deployed on a climatically significant scale, this approach would relocate acidification from the upper ocean to mid- or deep water, where biota may be more sensitive to pH changes: Cao, L. & Caldeira, K., ‘Can Ocean Iron Fertilization Mitigate Ocean Acidification?’ (2010) 99(1–2) Climatic Change, pp. 303–11; Caldeira, K. & Duffy, P.B., ‘The Role of the Southern Ocean in Uptake and Storage of Anthropogenic Carbon Dioxide’ (2000) 287(5453) Science, pp. 620–2; Williamson, P. & Turley, C., ‘Ocean Acidification in a Geoengineering Context’ (2012) 370(1974) Philosophical Transactions of the Royal Society A, pp. 4317–42.
