CERNOBBIO, Italy, Sept 4 (Reuters) – Europe will miss a key climate target for cutting greenhouse gas emissions by more than 20 years unless it picks up the pace on energy transition measures and improves governance, a study involving Europe’s biggest utility Enel (ENEI.MI) said. At the current pace, Europe will only reach its 2030 target for a 55 percent reduction in greenhouse gases in 2051, a study by Enel Foundation and the European House-Ambrosetti said. The study, presented on Saturday, said investments of around 3.6 trillion euros ($4.3 trillion) were needed across the bloc to reach 2030 goals, with a potential cumulative impact on the EU’s economic growth of more than 8 trillion euros. But it warned the EU needed to step up its efforts if this potential was to be realised. He said at the current pace Europe would only reach its 2030 target of raising the share of renewable energy to 40 percent of final consumption in 2043.
