Description: It's set to be a busy and interesting few days in Brussels as EU sustainable energy week is back. Head of the commission's DG energy Dominique Ristori kicks off our cover feature by pointing out that "it comes at a crucial time, just six months before the COP21 summit in Paris, during which the EU will be pushing for an ambitious agreement to decarbonise the world economy". And as head of DG climate change Jos Delbeke highlights, "all parts of society have a role to play. This year's sustainable energy week makes a valuable contribution to the discussion by focusing on the role of consumers, shedding light on what every one of us can do in our daily lives". We also hear from a host of MEPs, including Ivo Belet, who outlines how the reformed emissions trading scheme "will put Europe back on track to reach its 2030 climate target".
