This judgment follows proceedings that the Urgenda Foundation brought in 2013 against the State, claiming that the State was not taking sufficient measures to protect its citizens from the adverse effects of climate change. Dutch law permits foundations or associations to bring actions of general interests of this type.

As part of its international commitments, the European Union has set a greenhouse gas emission reduction target of 20 percent by 2020 (40 percent by 2030) compared to 1990 levels. To achieve this target, the European Union adopted two specific instruments:

The Emissions Trading System ("ETS")—the EU "cap-and-trade" system—covering greenhouse gas emissions from a wide range of large-scale industrial facilities and the aviation sector; and

The Effort Sharing Decision, setting individual greenhouse gas emission reduction targets for Member States in non-ETS sectors (e.g., agriculture, waste) from 2013 to 2020.

The Court of Appeal found that there is a real threat of dangerous climate change, resulting in the serious risk that the current generation of citizens will be confronted with loss of life and/or a disruption of family life.

Although the Netherlands was on track to reduce its greenhouse gas emissions in accordance with the EU program, Urgenda introduced proceedings in 2013 to seek more ambitious targets. It requested that the District Court find that the State was acting unlawfully by not taking appropriate measures to reduce the level of greenhouse gas emissions in the Netherlands by 40 percent by 2020 or at least 25 percent compared to 1990 levels. It referred to the level deemed necessary by climate scientists for developed countries to prevent hazardous climate change.

Urgenda based its claims on the principle of proper social conduct under Dutch law as well as the duty of care enshrined in Articles 2 and 8 ECHR, which provide for the right to life and the right to respect for private and family life.

In an initial judgment of June 24, 2015, the District Court agreed with Urgenda that the State's conduct violated proper social conduct. With regard to Articles 2 and 8 ECHR, the District Court held that Urgenda itself could not be considered a direct or indirect victim of a violation of these provisions, within the meaning of Article 34 ECHR.

The State appealed the District Court's ruling, pursuant to which Urgenda filed a cross-appeal relating to the District Court's finding on Articles 2 and 8 ECHR.

The Court of Appeal upheld Urgenda's cross-appeal. It found that Article 2 ECHR imposes a positive obligation on a state to protect the lives of its citizens and that Article 8 ECHR mandates the state to protect the right to a home and private life. When there is a real and imminent threat, it held, the state must take precautionary measures to protect these rights.

Applying these requirements, the Court of Appeal found that there is a real threat of dangerous climate change, resulting in the serious risk that the current generation of citizens will be confronted with loss of life and/or a disruption of family life. Based on its review of the State's reduction plan, the Court of Appeal deemed the margin of uncertainty unacceptable.

In a letter of October 9, 2018, the Minister for Economic Affairs and the Climate informed the Dutch Parliament that the Dutch government was considering an appeal to the Dutch Supreme Court. The Minister referred to a question of principle of judicial interference in governmental policies. The Minister further indicated that according to the latest estimates, the 25 percent reduction target was within reach and that the Dutch government remained fully committed to the policy goals set out in the Energy Agreement for Sustainable Growth, a nonbinding document that aims at reducing energy consumption and increasing the share of sustainable energy in the Netherlands.

The Urgenda case may give rise to similar claims in other EU Member States or at the EU level; in fact, a case is already pending before the European General Court. Applicants representing 10 families from EU and non-EU Member States, as well as an association of young Sami people, have brought an action against the European Parliament and the Council before the EU General Court ("EGC") (Case T-330/18) to urge EU institutions to adopt more stringent greenhouse gas emission reduction targets.

The applicants filed an application to the EGC to seek the annulment of the emission targets set out in three legislative acts that are part of the 2030 climate and energy framework. In addition to annulment, the applicants seek injunctive relief from the EGC to require the EU institutions to enact a more ambitious greenhouse gas emission target of a reduction by 2030 of at least 50–60 percent from 1990 levels.
