Carbon Finance

This chapter examines carbon finance as a central climate-finance mechanism that differs from green and blue finance by operating through prices rather than earmarked proceeds. It explains how carbon finance translates greenhouse gas emissions and emissions reductions into financial variables that can be priced, traded, hedged, and governed, thereby turning mitigation into an investable proposition. The chapter traces the evolution of carbon finance from the Kyoto Protocol’s market mechanisms to the more complex architecture that has emerged under the Paris Agreement, including compliance emissions trading systems, carbon taxes, offset credits, derivatives, and related governance infrastructures. It then reviews the prevailing carbon finance systems, with emphasis on the expansion of emissions trading systems across jurisdictions and the growing interaction between compliance and voluntary carbon markets. Particular attention is given to governance, highlighting the importance of measurement, reporting, and verification, enforcement, transparency, accounting integrity, and institutional credibility for sustaining effective carbon pricing. The chapter further synthesizes major theoretical perspectives—welfare economics, political economy, and financial economics—to show that carbon finance is best understood as a governance-embedded financial institution rather than a narrow market mechanism. The chapter concludes that carbon finance can play a pivotal role in the net-zero transition, but only when price signals are credible, market integrity is protected, and institutional design aligns financial incentives with long-run decarbonization objectives.
