In response to a written question concerning the funding which will be available specifically for environmental improvements in the planning, building and further development of TENs, Commissioner Bjerregaard said that there are no specific financial amounts made available for environmental improvements in the planning, building and further development of Trans-European network projects (TENs). The main Community instruments covering the financing of TENs projects are the Structural Funds (i.e. European Regional Development Fund), the Cohesion Fund, the proposed Regulation on Community financing and the Commission's budget line in the field of TENs and, as regards loans and loan guarantees, the EIB and the EIF. Assistance from these funds may be granted for preliminary studies or technical support measures. This type of assistance could contribute to environmental improvements in the planning and further development of TENs. It is important to note that in accordance with the principles and objectives of Community environmental policy (sustainable development and integration), it would not be desirable to separate the environmental cost from other types of costs in a TEN project.
