Our raison d’etre as a higher tier, problem solving consultancy is to work with clients to find novel solutions to often very complex regulatory issues. In doing so, we have often found ourselves pushing the boundaries of current regulatory frameworks, identifying limitations and data gaps that need to be addressed. For over 15 years, Cambridge Environmental Assessments (CEA) has been developing state-of-the-art regulatory risk assessment methods and undertaking research to help inform policy advice and research for government agencies and to advance the regulatory world in which our commercial clients operate.

We often present our work at conferences and workshops, using these forums as a platform to communicate our approaches, sharing and discussing our experiences with other regulatory scientists. This has led to CEA producing over 100 posters and platform presentations since 2005. To celebrate this achievement, and also to make this work easily available to all interested parties, below you will find an archive with links to all of our conference posters and platform presentations since 2005, together with links to journal articles we have authored/co-authored, so that all our past posters and platform presentations can be downloaded for free.

Please feel free to contact us if you have any comments or questions about any of these publications.
