Demonstrated engagement from participants for a further Europewide take-up and rollout of results during and following the proposal are expected. The capacity to observe the environment, including space-based, in situ-based (air, sea, land) observation, and citizen observations should implement an open market consultation to gain insights into state-of-the-art technologies and ongoing developments, including prototypes and demonstration services coming out of relevant Horizon 2020, Horizon Europe, ESA and national projects. This could include new approaches for market consultations with suppliers, paying special attention to SME suppliers. Proposals should engage public and/or private procurers from each country participating (at national, regional or local level) that have responsibilities and budget control in the relevant area(s). The network(s) of public and/or private procurers created should investigate the feasibility of, test and prepare the launch of joint or coordinated procurements (PCP), which would ultimately develop innovative, fully tested, fit-for-purpose and cost-effective end-user services in the area of climate change adaptation and mitigation. These solutions should be based on a complete set of common needs and specifications. Finally, to facilitate future replication, a set of well-documented practices should be made available. Preparation activities for the joint or coordinated PCP will be supported, but not the costs of the procurement resulting from any PCP procedures.
