A Lost Opportunity? Environmental Investment Tax Incentive and Energy Efficient Technologies

Abstract This paper examines the impact of the Spanish Environmental Investment (EI) tax credit on adoption of green technologies by employing data from 2567 industrial firms for 6 years. It makes use of the sudden re-introduction of the tax incentive in March 2011, that aimed at favouring energy efficient over solely pollution abating technologies. I exploit this unexpected change and perform a difference-in-differences analysis to study its effect on green investments and as an extention on green employment outcomes. The policy change, aimed at switching financing to energy efficient technologies, is assessed as semi-effective. Admittedly, it decreased investment in end-of-pipe technologies, but the investment in superior cleaner production technologies increased only for the small firms (below 50 employees), which are especially vulnerable to the capital market failure. Unfortunately, the policy change had also a few unexpected indirect effects, firms in response to the tax incentive regime modification reduced the number of their green employees and their associated salaries. In stark contrast to the decision of the Spanish government on this EI tax credit, the results of this analysis seem to be quite encouraging for the continued use of this green fiscal policy and show that the modifications in the precision of the existing fiscal policies can be successful.
