Fiscal and Monetary Policy Impacts on Environmental Sustainability
Summary
Fiscal and monetary policies shape environmental outcomes through multiple channels. Expansionary fiscal measures, such as increased government spending on infrastructure or subsidies for carbon-intensive industries, can exacerbate ecological degradation via scale effects, while targeted ‘green’ fiscal interventions—carbon pricing, environmental subsidies or public investment in renewable energy—can drive the transition towards low-carbon technologies. Monetary policy interacts similarly: lower interest rates and enhanced credit provision may stimulate economic activity, raising resource consumption and emissions, yet central banks can also influence sustainability by integrating climate risk into collateral frameworks or supporting green bonds. The composition of fiscal outlays and the orientation of monetary instruments therefore determine whether policy fosters a ‘technique effect’—improved efficiency and cleaner production—or reinforces unsustainable growth trajectories. Institutional quality and governance modulate these relationships, mediating policy design, implementation and long-term environmental stewardship. Theoretical and empirical advances highlight the importance of policy coordination: combining carbon pricing with monetary incentives for green investment can achieve decarbonisation goals without compromising economic stability. Globally, case studies—from emerging markets to advanced economies—demonstrate that aligning macroeconomic frameworks with environmental objectives is essential for meeting net-zero targets and ensuring resilient, sustainable growth.
