International Affairs Division

The International Affairs Division is responsible for Switzerland's international environmental policy. It thus forms part of the country's foreign policy system and is led by the Swiss Environmental Ambassador. The Division coordinates and develops Switzerland's political and strategic positions on international environmental questions and manages international negotiations and processes in this area. Of particular importance is the direct involvement of the FOEN's scientific and technical expertise. International Affairs therefore cooperates closely with the other FOEN Divisions and with other relevant federal authorities.
