The OECD’s Working Group on Harmonisation of Regulatory Oversight in Biotechnology (the Working Group) comprises delegates from the 33 member countries of OECD and the European Commission. Typically, delegates are from those government ministries and agencies, which have responsibility for the environmental risk/safety assessment of products of modern biotechnology. The Working Group also includes a number of observer delegations and invited experts who participate in its work, such as Argentina; the Russian Federation; the United Nations Environment Programme (UNEP) and; the Secretariat of the Convention on Biological Diversity (SCBD); the Food and Agriculture Organization of the United Nations (FAO), the United Nations Industrial Development Organisation (UNIDO); and the Business and Industry Advisory Committee to the OECD (BIAC). In recent years, with the increasing use of biotech products in many regions of the world together with the development of activities relating to tropical and subtropical species, there has been increased participation of non-member economies including Brazil, Cameroon, China, Estonia, India, the Philippines and South Africa.
