Abstract: This paper investigates whether and how diversified firms in the Information and Communication Technology (ICT) sector innovate in green technologies and assess the potential impact of these innovations on firm performance. The analysis relies on a balanced panel dataset of European ICT firms in the period 2009–2013. The results suggest an inverted u-shaped relationship between the extent of technological diversification and the likelihood to develop green technologies. Technological diversification generally increases the likelihood of green innovations, but too high a dispersion of resources across a large variety of different technologies decreases the intensity of green innovations. The results show also that the development of green technologies is positively associated with firm performance: ICT firms involved in green patenting activity perform better than ICT firms with no green patents.
