Summary of Firms’ Response to Climate Regulations: Empirical Investigations Based on the European Emissions Trading System

Introduction

This study examines how firms respond to stricter climate regulations using the European Union Emissions Trading System (ETS). It leverages a large cross-country dataset merging firm-level financial data with climate policy indicators. Carbon pricing affects firms by increasing costs, but its impact on profitability and investment varies.

Key Findings

• Overall Impact: Stricter market-based climate policies do not significantly reduce average firm profitability or performance. Firms adapt through investment and revenue adjustments.
• Non-ETS Firms: During high carbon prices, these firms face increased input costs but compensate by boosting turnover, maintaining profitability.
• ETS Firms: Firms with payable emissions see higher investment in intangible assets during periods of high carbon prices, indicating a shift toward low-carbon technologies. Profitability remains stable on average due to cost adjustments and revenue growth.
• Carbon Price Effects: High carbon prices amplify investment responses, particularly for regulated firms, but do not negatively impact most median firms assessed through quantile regression.
• Robustness: Results hold across various model specifications, distribution checks, and additional controls, confirming the main conclusions.

Methodology

The analysis uses a novel dataset combining firm financials from 12 European countries with ETS data and OECD Environmental Policy Stringency Index. Panel regressions and quantile regression assess heterogeneity based on ETS regulation status and carbon price levels.

Conclusion

Market-based mechanisms like the ETS effectively encourage emission reductions without severe economic burdens for most firms. However, policy design must address distributional effects to ensure fairness and efficiency in achieving climate goals.
