ESG governance

An overview of our governance structure and responsibilities.


Our ESG commitments are underpinned and supported by a strong and robust governance structure.

In October 2020, we established an Environmental, Social and Governance (ESG) Committee comprising members of our board and senior leadership team.

The committee is responsible, on behalf of the board, for overseeing the development of the group’s ESG strategy and governance structure, and the establishment of related goals and policies.

The committee is supported by an ESG Steering Group and an ESG Working Group, both of which implement the strategy and facilitate the delivery of ESG initiatives across the business.

The ESG Committee

The main purpose of the committee is to represent the board in defining the company’s strategy relating to ESG matters and to review the practices and initiatives of the company relating to ESG matters, while ensuring they remain effective and up to date. The ESG committee is chaired by a senior independent non-executive director every quarter. Established in October 2020, the ESG Committee is primarily responsible for:
