Our first global benchmark on modern slavery reveals that the 100 largest global listed companies (UK companies excluded) underperform the 100 largest UK companies benchmarked at the end of 2025. 

At CCLA, we dedicate significant effort to engaging with individual companies to enhance their approach to addressing modern slavery. To support this work, we also engage with UK policymakers aimed at pushing for more progressive modern slavery legislation. One such example is our engagement with the Home Office Forced Labour Forum.

The CCLA Modern Slavery UK Benchmark 2024 shows that the number of leading UK companies finding evidence or indicators of modern slavery has increased. More UK companies are taking steps to address the issue, with average scores rising. But there is significant room for improvement in corporate responses to modern slavery, especially in helping its victims. 

Our annual Find it, Fix it, Prevent it report outlines progress made by investors to combat modern slavery in company supply chains. Supported by investors with collective assets under management and advisory of £15 trillion, it has three complementary workstreams: corporate engagement, public policy and developing better modern slavery data.

Delegates at a recent roundtable on modern slavery in the construction sector acknowledged that the risks of modern slavery in the sector are significant and increasing, and that there is a pressing need for the sector to take action. 

CCLA's first benchmark on modern slavery seeks to create an objective assessment of corporate modern slavery performance. Findings show that while companies have policies in place, companies need to focus on implementing these policies and taking action when they find modern slavery.

CCLA launches its first Modern Slavery Benchmark. The benchmark assesses the largest UK companies on how they are taking steps to eradicate modern slavery in their operations and supply chains. 

This paper looks at whether the integration of artificial intelligence and other new technologies could revolutionise the way investors and businesses address modern slavery risks.
