Research & Analysis
Joshua Thumim
Head of Research & Analysis
Joshua has extensive experience of research in the fields of renewable energy, energy policy-making and energy strategy. Before coming to CSE as Head of Research and Analysis, he was first Strategy Adviser and then Principal Policy Officer with regard to energy at the Greater London Authority, where he was involved in managing and designing a wide range of research and implementation projects around themes of renewable energy deployment, energy efficiency and fuel poverty.
Joshua's experience includes:
- researching, collating, mapping and presenting energy and CO2 emissions data for use in the Mayor of London's Energy Strategy
- analysing the effects of various energy policy scenarios in relation to climate change
- providing energy expertise in planning negotiations and decisions
- leading on policy input into the development of the Climate Change Agency
- developing, fundraising and managing a London-wide study of the opportunities for community heating and CHP through biomass
A tangible example of Joshua's success in integrating the results of sustainable energy research projects into mainstream work of local energy developers and planning authorities, is the fact that 11 of the 36 London Boroughs now have energy planning policy documents based on work that Joshua pioneered between 2000 and 2005.
Joshua holds an MSc in environmental technology (specialising in energy policy) and a BSc (Hons) in chemistry. He has previously lived and worked in France and the USA, where he researched issues related to petroleum resource depletion and climate change.
