“…Most of the new categories are located at levels 3 and 4 of the taxonomy trees (as presented in Appendix A). Research has shown that the more specific and detailed the measures for coping with risk, the greater the control and understanding of the risk (as described in [1,34,35]). It is noteworthy that the new taxonomy includes new categories, and some categories have been removed compared to Boutang The taxonomy has evolved between the two NDC editions in terms of project categories.…”

The authors have proposed a method of reiterating the statistical analysis of the Nationally Determined Contributions (NDCs) of the UNFCCC Parties, which were updated at Conference of the Parties-26. The present analysis confirms the taxonomy developed in 2020, based on 2475 adaptive solutions recorded in 2022 NDCs, and discusses the differences observed. An ex ante adaptation metric is proposed, which allows monitoring of adaptive solutions over time and comparisons between projects in time and space. The fitness coefficient evaluates the ex ante relevance of these adaptive projects in relation to the climate challenges of each country. The authors have proposed a program of continuous improvement instead of a definitive calculation. The authors have developed an algorithm to automate the text analysis and minimize the subjectivity of the analysis. The objective is to assign a level of vulnerability to each project for each hazard in the country. The correspondence analysis was used to derive the most representative dimensions of project category dispersion and vulnerability intensities from a contingency table for each hazard. This coefficient can be made available to experts, project developers, and funders for ex ante evaluation and selection of candidate projects for funding before more in-depth analyses are carried out.

“…It has been acknowledged that the "Avoid-Shift-Improve" approach is strategic to achieve net-zero carbon by 2050 under the 2015 Paris Agreement [3][4][5]. This holistic approach is focused on (i) "avoiding" unnecessary travel needs through urban redesign, (ii) "shifting" to sustainable transport modes, and (iii) "improving" the travel experience of sustainable modes [5][6][7][8]. The superblock model integrates "avoid" and "shift" strategies by reclaiming public space and promoting sustainable mobility [9].…”

The present study contributes to narrowing down the research gap in modeling individual door-to-door trips in a superblock scenario and in evaluating the respective impacts in terms of travel times, modal shifts, traffic performance, and environmental benefits. The methods used are a multiple-criteria approach to identify the superblocks and a large-scale, multi-model, activity-based microscopic simulation. These methods were applied to the city of Bologna, Italy, where 49 feasible superblocks were identified. A previous large-scale microscopic traffic model of Bologna is leveraged to build a baseline scenario. A superblock scenario is then created to model five proposed traffic intervention measures. Several mobility benefit indicators at both citywide and superblock levels are compared. The simulation results indicate a significant increase in walking time for car drivers, while the average waiting time of bus users decreases due to the increased frequency of bus services. This leads to a noticeable car-to-bus shift. In addition, absolute traffic volumes and traffic-related emissions decreased significantly. Surprisingly, traffic volumes on the roads around the superblocks did not increase as expected. In general, this research provides scientists and urban and transport planners with insights into how changes in door-to-door travel times of multi-modal trips can impact individual travel behavior and traffic performance at a citywide level. However, the study still has limitations in modeling the long-term effects regarding changing activity locations within the superblocks.
