This  explores how drivers have varied over time, and how they vary today across the world (Waste Manage Res 2007, 25 (3), 198-207). DCW also co-authored a paper on ‘Using research-based knowledge to underpin waste and resources policy’ (Waste Manage Res 2007, 25 (3), 247-256), which examines the theory and practice of ‘evidence-based policy making’ in the waste and resources field.
