The objective is to prepare a sustainable follow-up of TESTNET in the form of two testing networks (water technology and clean production, including environmental monitoring). A financial sound and reliable structure and organisation of the testing networks will be aimed at. For this purpose an active involvement of relevant stakeholders to the networks is considered of utmost importance.
For each of the selected technology areas a stakeholder group will be established. This stakeholder group should be well balanced to ensure high quality of the verification protocols and to make the test results useful for both purchasers and permitters. Possible backgrounds of the stakeholders might be vendors, purchasers, permitters, financiers, researchers, normalisation organisations, environmental organisations, branch organisations, technological and/or verification consultants etc.
The lessons learned from the ETV programme of EPA (USA) will be incorporated.
An inventory of relevant test and research institutes will be made to identify the most suitable institutions to run the networks.
The overall market potential and impact of the developed verification system, both inside and outside the European Union will be assessed.
The financing structure of the testing networks will be discussed to identify the most feasible financial structure of the networks.

From the development of verification system design and technology testing case input will become available for describing the structure and organisation of the verification system. Special attention will be given to the quality assurance measures, the participation of the stakeholders and the financial sound set up.

Preliminary ideas for the future testing centres will be extracted from the IPTS study on the design of a European Environmental Technology Verification programme. In this study, it was concluded from a review of existing verification programmes and interviews with stakeholders, that the future testing networks should:

• Coordinate verification activities
• Be a driving force with political and management responsibilities
• Develop performance criteria in compliance with quantitative objectives of ETAP
• Guide and supervise the verification entities
• Advise the vendors
• Include Member State representatives
• Coordinate a network of national ETV agencies (either independent or dependant of national governments).
