David is principal of a consultancy on strategy and human change for environmental sustainability and is also currently project managing a substantial industry : university joint project to encourage the industrial adoption of low carbon technologies.

David has a strong background in business having spent his early career in increasingly senior roles in Finance, Strategy and Marketing with the Royal Mail, Esso Europe Inc. and THORN EMI. On leaving THORN he worked as an Environmental Consultant until 1995. He was then invited to become a Director of Bath Consultancy Group, one of the UK's most respected organisational learning and strategic change consultancies. Here he deepened his ability to work with complex human responses to environmental issues.

Since 1998, David has devoted his professional life to the challenge of sustainable development, with a particular interest in human responses to issues such as climate change. As a sustainability consultant, he worked for several years for one of the UK's leading construction companies and is now widely in demand for leading edge work on behavioural change. He is also a Visiting Fellow at the University of Bath, where he teaches on its innovative MSc in Responsibility and Business Practice.

Building on a successful career as a BBC programme maker (three national awards, two in the field of sustainability) and political researcher, Susan helped to launch the consultancy, Alexander Ballard and Associates following a high-profile climate change web project for Oxford University.

Susan's interest in social responses to climate change has grown from a long term practice advising senior scientists how to communicate to the public and a now interrupted training in psychotherapy. Susan is in a unique position to marry the scientific information she gains through her work at the Natural Environment Research Council, The British Antarctic Survey and The Institute of Animal Health, among others, to systemic processes for behavioural change based on a solid grounding in psychology, learning theory and mass communication.

Alongside her consultancy work she is pursuing doctoral action research which draws on psychological theories about identity, collective will, destructive addictive behaviours and creativity to develop more effective responses to climate change.
