TAKE AWAY-
AUDIENCE
• Transparency and guidelines for all 
stakeholders
• No competition with existing standards
• One goal is a proposal for a certification 
scheme
• Public hearing on the standard will be 
outside this project
TAKE AWAY -
PARTNER
• Exclusivity in the jointly developed results
• Everyone can derive their exclusive 
actions from the JIP result.• Workshops with open exchange of all 
partners in a closed JIP
• Very short project duration
• Shared costs in the case of joint 
knowledge gains*
