Professional Services Sustainability Initiative (PSSI)

Professional Services Sustainability Initiative

The Initiative brings together business leaders from seven professional services firms in the UK who believe there is an urgent need to develop new and longer term policies and approaches for tackling sustainability challenges.

Professional service firms play a pivotal role in today’s global economy, providing confidence to capital markets and enhancing the quality of corporate management and performance. The members of the PSSI are keenly aware of their social and environmental responsibilities as well as the opportunity to contribute to a strong, stable and sustainable economy – one that operates within environmental limits and ensures a strong, healthy and just society.

Through their advisory, assurance, consultancy and other services, and the effective management and positive example of their own operations, professional service firms have the potential to: 

  • Enhance their own positive impact and help to shape more sustainable supply chains
  • Inform and influence clients, policy-makers and other decision makers in support of sustainability


The PSSI Principles, launched in 2010, represent the members’ collective commitment to take action in support of sustainability on an ongoing basis. The Principles are reinforced by the actions of each of the group’s members, and by a collaborative action-oriented work programme to tackle priority issues for each of the Principles.

The PSSI Founding Members

The Initiative was formed by a cross-section of professional services firms in the UK who believe there is an urgent need to develop new and longer-term policies and approaches for tackling sustainability challenges.
