Jayne is a co-founder and Director of the sustainability and behaviours research company Brook Lyndhurst. Most of her research is commissioned by UK and devolved governments and their partners, often to support the development of complex interventions in nexus fields, as well as for evaluation. A notable example is the long-running Love Food Hate Waste initiative from the UK’s Waste & Resources Action Programme (WRAP). Jayne has also led a wide range of evaluations of environmental behaviour change programmes in the UK, especially of programmes funded by government and delivered by community-based organisations. Examples include the Scottish Climate Challenge Fund, Defra’s Inspiring Sustainable Living Fund and the Welsh Government’s Cynefin change programme. Before setting up Brook Lyndhurst Jayne was an investment analyst for 10 years in the commercial property sector.
