More and more is expected of companies in the field of ESG. Especially in the area of the “E” (Environment), much is going on. In the Shell v. Environmental Defense ruling of May 2021 (“Shell ruling”), the court adopted a private law climate care obligation requiring Shell to reduce emissions by a net 45% by 2030 (compared to 2019). This ruling has created an uncertain playing field for companies and financial institutions. There are significant questions about the scope of the climate care obligation and how it should be shaped in practice. Meanwhile, pressure is on entities to come up with an ambitious and concrete climate plan as soon as possible. In a recent letter to 29 “major polluters,” Milieudefensie Foundation set the deadline for climate plans at April 15, 2022. The climate plans will then be put under a magnifying glass. Laggards are expected to face subpoenas. Therefore, the pressure is on. This article outlines the status quo, discusses the climate duty of care and then aims to provide some starting points for preparing a climate plan.
