This report first outlines the nature and potential of GNAs (Chapter 1), and then turns to lessons from experience with GNAs in Scotland and elsewhere – particularly the US (Chapter 2). Chapter 2 also draws lessons from literature on other negotiated and voluntary agreements. Chapter 3 examines how GNAs might work in Scotland – in particular, considering potential for GNAs to be linked to planning permissions or pollution licenses, or to stand alone as private legal agreements. It also anticipates concerns that businesses might raise. Chapter 4 proposes a tentative template and guidelines for Scottish GNAs. Chapter 5 discusses some of the issues raised by GNAs in more depth and draws conclusions.
