Climate change calls, among other actions, for rapid market penetration by energy-efficient, low-carbon technologies that substitute fossil-fuel powered products. There is a need for identifying and analyzing socio-political and technological processes stimulating market growth in order to design transformative pathways. Real-world market growth of innovative technologies is typically not a continuous process, but characterized by intermittent phases of acceleration, stagnation or even relapse. Thus, targeted policy actions need to identify and explain turning points of accelerated market diffusion of low-carbon technologies. On a wider note, the TIMELAG project strives to advance the discussion on dynamic and pace of technology diffusion.
