Paul received a BSc (Hons) in chemistry from the University of Bristol (UK) in 1979 before spending 15 years with BP Chemicals in a variety of technical, technology transfer and commercial roles. In 1994, Paul set up his own consultancy firm, Caleb, to pursue his growing interests in the environmental regulatory field. Caleb continues to be an active opinion-former in international policy development based on its strong track record in support of the Montreal Protocol. It has a significant core business in the chemical regulatory field and has been one of the lead consultancies on the implementation of REACH within the European Union. In order to broaden its global base, Caleb reached an agreement with sustainability specialist, Anthesis Consulting Group, to combine forces in February 2014. Paul is now responsible for the global development of the Sustainable Chemistry practice for Anthesis-Caleb.
With a strong personal profile in both the ozone and climate agendas, Paul has taken particular interest in the management of chemicals throughout the lifecycle of products and the approaches being taken to move to greener chemistries. In particular, Paul has focused his attention on Alternative Assessment methodologies being developed in both the EU and in North America, in the light of over 20 years’ experience in the assessment of technologies under the Montreal Protocol. Apart from his role as co-chair of the UNEP Foams Technical Options Committee since 1998, Paul has been additionally active as a “lead author” of a series of influential reports for the Inter-Governmental Panel on Climate Change (IPCC). He is particularly focused on the inter-linkages between various international environmental treaties in his efforts to encourage ‘joined-up thinking’ in international policy.
