Genetically modified organisms (GMOs) are the subject of legislation and regulations which spell out how they may be used in Sweden, and which authorities users should turn to on various issues relating to them.
Under chapter 13 of the Swedish Environmental Code, a consent (permit) or notification is required for all activities involving genetically modified organisms (GMOs). Prior to any contained use or deliberate release of GMOs, an investigation must be carried out as a basis for a risk assessment of the activity in question. This risk assessment then determines what protective measures need to be taken. A consent for an activity involving GMOs may only be granted if the activity is ethically justifiable.
