Metis is the journal of IPPR@universities, the student thinktank network. This year's theme - the environment - has provided the opportunity for students to think about the difficult policy issues that will directly affect their futures. Unsurprisingly, all the essays express the urgent need for long-term thinking and policymaking.

Metis aims to provide students with the opportunity to engage with the policy process and gives them a unique platform to express opinions, critiques and solutions. The third volume of Metis shows how much the IPPR@universities programme has grown since 2010. This year's edition features contributions from four universities - Warwick, Sheffield, York and Manchester.

Edited by Marc Geddes from the University of Sheffield, the third issue of the journal features eight essays by student thinktankers:

  • Guy King, Sheffield - A balancing act: ethical consumption and waste
  • Iuean Ferrer, York - The case for a meat tax
  • Efraim del Campo Parra Munoz, Sheffield - British politics and GM crops
