Social Life Cycle Assessment (S-LCA) is a methodology developed in order to assess the negative and positive social impacts of products and services, along their life cycle. Guidelines for S-LCA were first published in 2009 as a project of the UNEP/SETAC Life cycle Initiative (today UN Environment Life Cycle Initiative). In the last 10 years, further developments and numerous implementations have been carried out, defining in more detail the methodology, its indicators and impact assessment methods. After those ten years, a revision of the current version of the Guidelines became necessary. The project for the revision of the Guidelines of Social Life cycle assessment of Products, and the related Methodological Sheets started in September 2017 led by Social LC Alliance. the review project was sponsored by the UNEP Life Cycle Initiative from May 2018 on. The project was designed with two main phases:

1. Methodological review of the Guidelines and update of methodological sheets
2. Implementation of the new Guidelines in pilot projects

This report presents the submitted reports of nine pilot projects conducted between 2019 and 2022 to test the applicability of the Guidelines as well as the benefits and challenges in its implementation.
