CCLA Modern Slavery UK Benchmark
CCLA Modern Slavery UK Benchmark
There are clear steps that companies can take to reduce modern slavery around the world. Large listed companies can be particularly influential in setting international norms and in efforts to find, fix and prevent modern slavery.

Pamela Bentley
The CCLA Modern Slavery UK Benchmark, launched in 2023, aims to:
- develop a framework on the degree to which companies are active in the fight against modern slavery
- create an objective assessment of corporate modern slavery performance aligned with statutory requirements, government guidance, and international voluntary standards on business and human rights
- support investor engagement with companies on their approach to modern slavery
- provide a vehicle for learning and sharing good practice
- create a mechanism to leverage business competition to drive improvement in practice.

Progress on the Living Wage
In early 2023, we commenced engagement with several UK-listed companies with the aim of persuading them to become Living Wage accredited. We chose companies in sectors where there is a high proportion of low-paid workers, namely hospitality and retail, as well as businesses with large call centres.
Also in 2023, we joined an alliance of financial institutions known as the Platform Living Wage Financials (PLWF). The alliance encourages companies to aim for living wages in their global supply chains. We are a member of PLWF’s apparel and textile working group and are part of the engagement working group for the following companies.
The outcomes of our engagement on the Living Wage in 2024 are set out below.

Discussions continue.
LVMH Moet Hennessy Louis Vuitton
Consumer discretionary
LVMH is a focus of our engagement under PLWF. In June 2024, news emerged that Italian authorities had put LVMH subsidiary Dior under special measures after finding that the company had not taken sufficient measures to address the exploitation of Chinese migrant workers in northern Italy.

Nestlé
Consumer staples
As part of PLWF, we have been engaging with Nestlé to ensure that workers in the company’s supply chain are paid a living wage or have a living income.

NextEra Energy
Utilities
In 2023, CCLA joined the UN PRI Advance work programme as lead investor for NextEra Energy. The focus of the engagement is the company’s approach to human rights – in particular, forced labour in its solar panel supply chain. During 2023, the company confirmed a new onshoring/nearshoring/friendshoring strategy for solar and said that it was working on a new human rights policy. We met to discuss this with the company in July 2024, but it became clear that little progress had been made. A shareholder proposal has been filed at the company, which we plan to support when it goes to vote.
