The deliberate release into the environment of GMOs is either carried out as so-called field trials (also referred to as deliberate release for any other purpose than for placing on the market) or as placing on the market of a product. Deliberate release has to be authorised and requires thorough risk assessment of possible health or environmental effects of the GMO. The consent for field trials is granted by the Board for Gene Technology in Finland. The consent for GMO products to be placed on the market is granted through a centralised authorisation procedure in the EU, and the authorised products can then be marketed in the whole area of the EU.
