FY25 Sustainability Report

RSK demonstrates how a large global organisation can embed sustainability across more than 200 businesses and their supply chains

As we present our FY25 Sustainability Report, we reaffirm RSK’s commitment to creating lasting positive impact for our planet and people. This year has marked significant progress in our journey as we report for the first time, a full financial year of delivering Second Nature, our group’s 2030 sustainability strategy.

Second Nature aims to mainstream sustainability, making it the instinctive way we operate across our family of businesses, our value chain and beyond. Given RSK’s large group structure, one of the most important elements in this strategy is our business-level ESG plans. The creation of these plans challenges each of our businesses to adopt KPIs that are meaningful to their operations while also supportive of the overall group goals.

This report outlines our key achievements over the past year, reiterates the goals we have set for the future and provides detailed metrics across topics most critical to RSK.
