Trevor Rees

I have worked in sustainability for more than 20 years, including in senior positions in international organisations in the role of strategic partnerships and business development.

I have designed and delivered programmes for corporate clients to help them develop skills and understanding for engaging with complex challenges relating to sustainable and responsible business practice. I have worked with leadership teams struggling to make sense of what ‘sustainability leadership looks like’, including through experiential field-based activities.

My own view is that sustainability is a narrative that is always changing and therefore where an organization finds itself at any given time is subject to a large number of internal and external drivers that are also shifting. I’m particularly interested in how organizations surface the tensions that exist between strongly held but abstract ‘values’ and external expectations around environmental / social impacts.

I don’t consider myself a content expert with respect to a specific aspect of environmental sustainability, I prefer to take an approach that enables the organisations I work with to ‘reframe’ and view challenges systemically.

I have significant experience of working with different sectors, recent engagements have included:
• Review of sustainability reporting guidelines for the oil and gas sector – I was asked to do this work as part of stakeholder panel for IPIECA (this is the global oil and gas association for environmental issues).
• Working with major UK retailers and tea-buyers to address social and environmental issues facing Kenyan Tea producers within their supply chains, a focus on energy has led to development of a catalytic intervention with potential for significant impact at scale.
• Design and implementation of field-based challenge as part of employee engagement programme for large, US based family owned business (working specifically with global drinks division) using an experiential approach to link core business with key sustainability challenges and origin community benefits.
• Development and management of large-scale sustainability leadership programme for major banks, focused on building competencies of diverse teams to build a values-led, high performance culture.

I work as a consultant with partners and clients from different sectors, I am an associate of Talik and Company and find this collaboration to be useful as it allows me to draw on a wider skill set of colleagues.

Although I describe myself as working in ‘sustainability’ for more than 20 years, I increasingly find this term unhelpful and tend to focus my work around questions of purpose and impact applied within a systemic context.
