Policies and Responsible Business Practices

Tetra Tech is committed to maintaining business practices that honour and protect the dignity and integrity of everyone with whom the company conducts business, employs and serves.

As a leading international development firm, Tetra Tech fully supports continued progress and improvement within the development community to make development initiatives more effective.  

We are committed to taking action within existing and future development activities to foster the realisation of the United Nations Sustainable Development Goals and to embed the principles of the Paris Declaration on Aid Effectiveness and the Accra Agenda for Action into our systems and procedures. We are also committed to addressing various cross-cutting issues relevant to international development to ensure that all people can access and enjoy the benefits of our activities.

Our commitments not only relate to Tetra Tech’s standards for aid delivery, but also to our expectations and aspirations for our entire organisation.

Equality, Diversity & Inclusion
Tetra Tech has a diverse and welcoming workforce. We strive to create working environments where people can thrive and where we are all continually learning about and understanding each other. Read our statement from Ben Ward, our Managing Director, to learn more about what we are doing to counteract societal inequality.
  • Modern Slavery Statement
Modern Slavery and Human Trafficking
We believe that all large international institutions – particularly those, like Tetra Tech, that work in countries that are still building the integrity of their workforce regulatory structures – are likely to be affected by modern slavery issues. Only by engaging in honest, supportive and collaborative dialogue within and across industry sectors about these problems will we begin to fully understand the challenges we all face and be able to design sustainable solutions.

In response to the UK government’s adoption of the Modern Slavery Act (2015), we have developed a statement outlining our commitment and actions towards ensuring the principles of the Modern Slavery Act are woven into our supply chains and business practices.
