THE HAGUE – A group of environmental organizations backed by thousands of Dutch citizens is launching a civil case Tuesday against the energy giant Shell, asking a court to order the multinational to commit to reining in its carbon emissions by 45% by the year 2030.The legal battle led by Milieudefensie, the Dutch arm of Friends of the Earth, is the latest in a string of cases around the world in which activists are using the courts as a venue to fight for action to reduce greenhouse gas emissions from governments and companies.A victory for climate activists in a Dutch courtroom could spur even more legal challenges.“Everybody needs to pitch in if we are to tackle the climate crisis, especially big polluters like Shell.
