The most interesting development in the Netherlands this year was foreseen in the report on 2014. The reasoning in, and consequences of, the Urgenda Foundation v The State of the Netherlands decision (Urgenda decision), will be discussed below. This now world famous judgment of the Dutch district court in The Hague has rightfully received much attention for being the first judgment that orders a state to do more against climate change. Although international environmental law has had its relevance for many of the developments in environmental law in the Netherlands, no new international environmental law treaty was published in the Bulletin of Treaties of the Kingdom of the Netherlands as no new treaties were ratified in 2015. It is therefore not surprising that most of the attention of environmental lawyers and academics in the Netherlands was drawn towards national (legislative) developments and European law. This report provides information on the ongoing process of restructuring environmental law in the Netherlands, the implementation of the Energy Agreement on Sustainable Growth of 2013, and the ongoing debate about onshore natural gas production in the north of the Netherlands). In addition, we discuss the environmental problems on the island of Curaçao caused by the Isla refinery.
