Synthetic biology has the potential to drive significant advances in biomedicine. But there are myriad scientific, social, commercial and legal issues, which policymakers have set out to address.

As biofuel production grew fourfold from 2000 to 2008, criticism of the industry seemed to increase nearly as dramatically. Production of these transport fuels, which are based on food crops such as grains, sugar cane and vegetable oils, competes with food crops and drives up food prices, experts argue. Also, from land-clearance needed for cultivation, production and use, these biofuels may actually increase, rather than reduce, greenhouse gas emissions.

Biotechnology has steadily evolved to become a potential motor of environmentally sustainable production and a proven source of a diverse range of innovations in agriculture, industry and medicine. Could we be at the dawn of a new bioeconomy? Public policies will influence the answer.
