“…This paper focuses on the UK, a mature European VC market [2], [20], [21], perceived as a leading exponent of low carbon finance innovations [22], [23], notably through the recently established Green Finance Institute (2019). The paper examines the supply-side role of VC as a key pivotal private finance provider where public sector co-financing assistance through Government Venture Capital Funds (GVCFs) [24], [25], can make a difference. Lessons from the UK's post-GFC GVCF market, from 2009 onwards [26], [8], are used to demonstrate how to create a more efficient financing escalator [27], [28], to assist early-stage cleantech ventures through the 'valley of death' from proof of concept to achieving secure market traction [29].…”
