New research published in Nature Climate Change explains why 18 countries, mainly in the EU, have managed to peak and then decline their CO2 emissions from fossil fuels over the past decade. There are three main reasons why: a declining relevance for fossil fuels, a fall in energy demand, and strong national policy frameworks. To find out more, check out an article for The Conversation written by SILCI team member, Charlie Wilson, who was involved in the research.
