Abstract
This paper examines whether the EU Emissions Trading Scheme (EU ETS) and innovation subsidies interact to enhance green innovation at the firm level. Using staggered difference-in-differences and matched samples, we find no evidence of synergetic effects: firms subject to both the EU ETS and innovation subsidies do not outperform those subject only to subsidies in terms of green patenting outcomes. By contrast, subsidies alone have a clear positive impact on green innovation. Firms receiving subsidies generate more green patents, receive more citations, and develop technologies with greater te
