The methodology of the EACC project is presented in this report. The Report is divided into five sections, starting with an introduction. Section II discusses a few peculiarities of the sole concept of adaptation, which make the problem theoretically and practically quite unique. Section III brings the previous theoretical discussion to a more operational level, including clearer definition of various commonly used terms. Section IV presents the four steps of the bottom-up methodology based on the country case studies. Section V describes the top-down methodology – how to estimate the global costs of adaptation based on global datasets, including major simplifying assumptions, data available, and sector methodologies; Section VI discusses the links between the bottom-up and top-down approaches.
