Financial barriers and environmental innovations: evidence from EU manufacturing firms

Environmental innovations (EI) are essential to achieve economic growth and environmental protection goals. Technological development is one of the key factors that can counterbalance the growth and population emission-augmenting effects. EI are a priority in major EU policy strategies and a prerequisite for the development of a ‘Resource efficient Europe’, one of the flagship initiatives of Europe 2020. The existence of financial barriers can constitute a serious deterrent for the eco-innovative capacity of firms, even more than for ‘traditional’ innovations, as EI are characterized by high technical risk, long payback period and uncertainty on the appropriability of private rents. This article analyses in depth whether barriers related to external financing affect EI investments and whether the stringency of financial constraints to investments in EI is affected by factors related to EI specificities. We show that when both direct and indirect effects on EI investments are considered, the role of the policy framework appears to be as particularly crucial in order to reverse the risk/return trade-off of eco-innovative investments. Targeting policy interventions to facilitate access to credit and to mitigate capital markets’ imperfections is essential to mitigate the apparent contradiction between EU industrial policies and climate abatement scenarios.
