Abstract:
We use machine learning algorithms to construct a novel news-based index of US environmental and climate policy uncertainty (EnvPU) available on a monthly basis over the 1990-2019 period. We find that the EnvPU index spikes during the environmental spending disputes of the 1995-1996 government shutdown, in the early 2010s due the failure of the national cap-and-trade climate bill and during the Trump presidency. We examine how elevated levels of environmental policy uncertainty relate to investments in the low-carbon economy. In firm-level estimations, we find that a rise in the EnvPU index is associated with a reduced probability for cleantech startups to receive venture capital (VC) funding. In financial markets, a rise in our EnvPU index is associated with higher stock volatility for firms with above-average green revenue shares. At the macro level, shocks in our index lead to declines in the number of cleantech VC deals and higher volatility of the main benchmark clean energy exchange-traded fund. Overall, our results are consistent with the notion that policy uncertainty has adverse effects on investments for the low-carbon economy hindering progress to address the urgency of climate action.

Abstract:
Achieving the goals of the Paris Agreement and of climate neutrality by 2050 in the European Union will require mobilizing financial investments towards clean energy innovation. This study examines the role of internal finance (cash flows and cash holdings) and financing constraints for innovation in energy technologies. We construct a dataset for 1,300 Europeans combining balance-sheet information and patenting activities in renewable (REN) and fossil-fuel (FF) technologies and estimate the sensitivity of patenting activities to's internal finance. We use count estimation techniques and control for a large set of-specific characteristics and market developments in REN and FF technologies. We find that patenting activities ofs specialized in REN innovation are significantly more sensitive to a shock in cash flows thans specializing in FF innovation. Hence, our results emphasize that innovatives in clean energy may be particularly vulnerable to financing constraints. We discuss the implications of these results for energy transition policies aiming to redirect finance towards clean energy R&D.

Abstract:
We build a novel news-based index of US environmental policy and examine how it relates to clean investments. Extracting text from ten leading US newspapers over the last four decades, we use text-mining techniques to develop a granular index measuring the salience of US environmental policy (EnvP) over the 1981-2019 period. We develop further a set of additional measures, namely an index of sentiment on environmental policy, as well as various topic-specific indices. We validate our index by showing that it correctly captures trends and peaks in the evolution of US environmental policy and that it has a meaningful association with clean investments, in line with environmental regulations supporting growing opportunities for clean markets. In firm-level estimations, we find that the salience of environmental policy in newspapers is associated with a greater probability of cleantech startups receiving venture capital (VC) funding and reduced stock returns for high-emissions firms most exposed to environmental regulations. At the aggregate level, we find in VAR models that a shock in our news-based index of renewable energy policy is associated with an increase in the number of clean energy VC deals and in the assets under management of the main benchmark clean energy exchange-traded fund. Overall, our EnvP index provides a lot of substantial information on environmental policy and can help assist the policy and financial community in understanding how these regulations are perceived by investors | providing many avenues for future research.
