On the basis of an overview of existing scenarios, the Intergovernmental Panel on Climate Change, in 2007, highlighted that in order to keep temperature rise to below 2°C, industrialised countries would need to reduce their emission by 80% to 95% by 2050. The European Member States agreed in 2009 that they would reduce their emission by 80 to 95% by 2050.
Subsequently the European Commission developed a 2050 low-carbon roadmap that contains a proposal for reducing the EU's domestic emissions by 80% by 2050. With the Paris Agreement calling for a 1.5°C temperature limit, these numbers are no longer valid. It is clear that the EU will need to substantially change its long-term pathway and achieve zero emissions well before 2050.
Several CAN Europe member organisations have long-term scenarios:see Greenpeace, WWF and International Network for Sustainable Energy (INFORSE)
