On May 28, 2021, Greenpeace Spain, Oxfam Intermón, Ecologistas en Acción, and Coordinadora de ONG para el Desarrollo filed suit alleging that the Government of Spain's climate plan was insufficient to meet Paris Agreement goals and the 1.5C temperature target. In March 2021, Spain approved the National Energy and Climate Plan 2021-2030. Plaintiff NGOs challenged the plan on the grounds that it was not ambitious enough to meet the Paris Agreement's temperature goals and did not uphold public participation guarantees required for an adequate environmental assessment. The case was filed by most of the same plaintiffs as those in a similar case
also challenging the National Energy and Climate Plan. On July 1, 2021, the Supreme Court admitted the case.
