Territorial transformations are currently influenced by the combination of multi-scale processes that generate complex change dynamics. In particular, we focus on the emerging conflicts between CO₂ reduction policies and the preservation of natural and ecosystem values on a the local scale. Global policies stimulate a generalized effort in promoting the transition towards a low carbon economy, and a relevant component of such a development process is connected with Renewable Energy Sources (RES). Such technological settlement processes in low density areas generate relevant impacts.

This paper discusses an ex-post-impact assessment methodology based on cumulative ecosystem services losses in a specific study area: the Melfi municipality in the Basilicata region (Italy).

The proposed methodology, starting from a temporal evolution of RES plants, considers the ecosystem services estimation based on InVEST tools in order to deliver spatial multicriteria maps of the resulting territorial impacts. These results allowed to clarified the limits of a local sectorial planning approach and highlighted the opportunities offered by performance-based planning in assessing alternative transformation scenarios.

The conclusions regard policy implications towards a multidimensional performance-based planning system where alternative low carbon transition scenarios could be compared in order to take into account territorial specializations and identity assets as a tool to drive decision-making in a sustainable planning perspective.

当前，地域转换受生成复杂变化动态的多尺度过程的组合影响。特别是，我们重点关注减少CO _2的政策与在地方范围内保护自然和生态系统价值之间出现的冲突。全球政策刺激了为促进向低碳经济过渡而做出的普遍努力，而这种发展过程的相关组成部分与可再生能源（RES）相关。低密度地区的这种技术沉降过程会产生相关影响。

本文讨论了一个基于特定研究区域：意大利巴斯利卡塔地区梅尔菲市的累积生态系统服务损失的事后评估方法。

所提出的方法从可再生能源植物的时间演变开始，考虑了基于InVEST工具的生态系统服务估算，以便提供由此产生的地域影响的空间多准则地图。这些结果可以澄清当地部门计划方法的局限性，并强调基于绩效的计划在评估替代性转型方案时所提供的机会。

结论涉及政策对基于多维绩效的计划系统的影响，在该系统中，可以比较其他低碳转型方案，以考虑领土专业化和身份资产，以此作为在可持续计划的角度推动决策的工具。
