Climate activists are threatening to sue Royal Dutch Shell to try to force it out of the oil business. A bloc of environmental groups in the Netherlands, where the company is based, says it wants to get a court ruling that would compel Shell to move away from fossil fuels and toward renewable energy. The groups say Shell is “deliberately obstructing” efforts to keep global warming well below 2 degrees Celsius, the key goal of the Paris agreement. The legal action would seek to hold Shell responsible under Dutch law for its contributions to climate change and all the environmental damage associated with it. Shell says it supports the Paris accord and is committed to cutting its carbon footprint in half by 2050.
