The latest EER contains papers from a symposium in Network 30 at the EERA-ECER conference in Porto in 2014.
The symposium had an international and inter-disciplinary focus on environmental, sustainability, global and development education research looking at ethical and political issues within these areas. It brought together researchers from Belgium, Canada, the Netherlands, and Sweden.
Helpfully, the journal has not just their papers but the contributions from two discussants as well: Sharon Todd and Stephen Gough. Reading these may well guide you to which papers are worth reading, and which might be best left well alone. There's a dedicated page promoting the special issue through which you can get free access to all the papers.
