This chapter identifies important limits relating to the difficulties of reconciling moral disagreement at a global level. It presents a case study of one important policy area in the field of environmental ethics, namely: the regulation of biofuels. The chapter considers experimentalism as an ethical approach to global governance. Experimentalist governance is typified by a concern with deliberative polyarchy, stakeholder inclusion, and democratic destabilisation. The chapter explores surveys the emergence of European Union (EU) standards of biofuels regulation. Biofuels are an interesting test case of experimentalism because the architecture of regulation emerged in precisely the unpredictable, 'experimental' fashion that might tend towards pluralist learning. The chapter reviews the critical potential of experimentalism to both expose democratic fragilities in global governance and provide pragmatic reflections on new directions in this area. Ethical attachments to a goal of sustainability have combined with the expansion of global governance to legitimate wider processes of market-making.
