Broad cooperation from a variety of stakeholders was critical to shaping the Report, its messages, and its added value to existing knowledge on climate change in Croatia. An initial scoping meeting with more than 30 representatives from the Government, academia, businesses, donors, and the NGO community helped to ensure that the Report could target gaps in existing knowledge and take advantage of ongoing research. In this meeting and during the series of consultations that preceded it, stakeholders identified adaptation as a key area to focus on – both because of the overall lack of information at the national level and the potential importance of the findings to policy-making in key economic sectors. Stakeholders also identified "critical sectors" that merited extra analysis in terms of potential socioeconomic impacts: coastal zones and water, agriculture and tourism. Croatian contributors to the Report were selected according to these priorities, and the project hired an international consultant with expertise in the relatively new and narrow field of economic modelling of the impacts and adaptation to climate change, to provide information on cutting-edge techniques to the Croatian experts. Following the initial meeting, the team of writers worked to involve more stakeholders – especially in sectors that might be affected by climate change. The participants in the process also organized a relatively informal advisory group that provided feedback on all sections of the Report.

The Report is truly inclusive in terms of the many organizations and individuals across Croatia involved in its content and analysis. Croatian researchers were extremely helpful in identifying regional or international research findings that were potentially relevant to Croatia in cases where national data were not available. Last, but not least, the Croatian public also contributed to the Report, with the opinions of 1,000 Croatians forming the lead chapter and resulting in a new understanding of the awareness and opinions of the Croatian public regarding climate change.

The review process for the Report also reflects a national and international effort. In Croatia, the Report was reviewed by members of the advisory group and several additional organizations in the form of both desk reviews and discussions during a one-day presentation of findings for the advisory group. Feedback and comments were also provided by three international experts and UNDP experts on climate change and human development at the regional and global level of the Organization. The final document greatly benefited from all the input received.

It should be noted that this Report is not seen as the definitive work on climate change in Croatia, but as a contribution to the ongoing national effort to address climate change, while promoting human development. Also, this Report aims to initiate a broad national discussion, including high-level decision-makers, on the impacts and vulnerability of the Croatian economy to climate variability and climate change: on challenges, costs and opportunities that a "climate-altered" world brings.
