Learning across levels of governance: Expert advice and the adoption of carbon dioxide emissions reduction targets in the UK

This paper is concerned with environmental governance and policy formation in the area of climate change. Specifically, it examines a decision by the UK Government in 2003 to adopt a demanding, long-term CO2 emissions reduction target, following the advice of one of its longest standing environmental advisory bodies, the Royal Commission on Environmental Pollution. It explores the origins of the Commission's recommendation and the reasons for its relatively rapid uptake in public policy. It argues that in both cases, a complex mix of structural and contingent, cognitive and non-cognitive factors can be identified, operating at different levels of governance. Finally, the paper reflects on what we might learn from this particular case about policy processes and the role of knowledge and expert advice within them.
