The article provides a critique of British environmental policy, focusing i
n particular on the role of sustainable development as an organizing princi
ple, the use of cost-benefit analysis (CBA) and economic instruments, and t
he design of the institutions responsible for implementing policy. It is ar
gued that, while considerable progress has been made in the theoretical lit
erature to define sustainable development, successive governments in the UK
have widened the definition to the point where it provides little guidance
for policy. Obstacles to the use of CBA are discussed, as are the politica
l constraints on implementing economic instruments-in particular, the incom
e effect. Finally, it is argued that the institutional design of the Enviro
nment Agency and the Department of the Environment, Transport and the Regio
ns partly explains the overwhelming reliance on command-and-control regulat
ion.
