Key Details
The ADB Working Paper Economic Policy Uncertainty and Carbon Emissions in Emerging Markets shows that while economic policy uncertainty generally increases carbon emissions, the effect depends heavily on institutional quality, climate policy and structural characteristics, making some emerging economies far more resilient than others.

Summary
Policy Uncertainty Does Not Affect Every Economy Equally
The ADB working paper Economic Policy Uncertainty and Carbon Emissions in Emerging Markets examines whether uncertainty surrounding fiscal, monetary and regulatory policy influences carbon emissions across 13 emerging market economies, including India, between 1990 and 2023. While the study finds that higher Economic Policy Uncertainty (EPU) generally leads to higher carbon emissions by discouraging long-term investment in clean technologies, it argues that this relationship is far from uniform. Instead, the environmental consequences of policy uncertainty depend on the institutional, economic and structural characteristics of individual countries.
The findings therefore shift attention from whether policy uncertainty matters to why some economies are far more resilient to it than others.
Institutional Strength Determines Climate Resilience
The study identifies several factors that substantially reduce the impact of policy uncertainty on emissions. Emerging economies with carbon pricing mechanisms, stronger political stability, deeper financial markets, greater trade openness, higher shares of renewable energy and stronger research and development (R&D) ecosystems experience either much smaller increases—or, in some cases, no significant increase—in carbon emissions during periods of policy uncertainty.
By contrast, lower-income economies and countries with weaker institutional capacity experience larger and more persistent increases in emissions. The analysis also finds that economies already facing high climate vulnerability often exhibit a weaker emissions response because climate risks have already encouraged stronger adaptation and mitigation policies.
Rather than treating climate policy in isolation, the paper argues that institutional quality itself has become a critical determinant of successful decarbonisation.
Uncertainty Delays the Low-Carbon Transition Through Multiple Channels
The paper explains that policy uncertainty affects emissions by changing investment and policy decisions rather than energy demand alone. Businesses delay investments in renewable energy, energy efficiency and cleaner production technologies when future policy signals become uncertain. Governments may also postpone environmental regulations or green infrastructure projects while prioritising short-term economic stabilisation.
These responses prolong dependence on carbon-intensive assets and slow structural transformation towards cleaner production. The study therefore argues that uncertainty affects the pace of the low-carbon transition, not simply short-term emissions.
What is Economic Policy Uncertainty (EPU)?
Economic Policy Uncertainty (EPU) measures uncertainty surrounding future government policies affecting the economy, including taxation, public spending, monetary policy, regulation and trade. Higher uncertainty often causes businesses to postpone long-term investments until policy direction becomes clearer. The ADB study finds that such delays can slow investment in renewable energy and low-carbon technologies, increasing reliance on carbon-intensive production during periods of uncertainty.
Policy Relevance
The study broadens climate policy beyond emissions targets, showing that a successful low-carbon transition depends as much on predictable macroeconomic governance and institutional quality as on environmental regulation.
For India, expanding renewable energy capacity must be accompanied by stable policy frameworks, with consistent energy, finance, industrial and investment policies helping sustain investor confidence through long investment cycles.
Green finance, deeper financial markets and stronger innovation ecosystems are integral to climate policy, making the energy transition more resilient to periods of economic uncertainty.
Carbon pricing, political stability, trade openness and institutional strength complement environmental regulation, reducing the risk that economic uncertainty translates into higher emissions and reinforcing the need for coordinated climate policy.
Long-term decarbonisation increasingly depends on broader economic governance, with investment certainty, financial resilience and institutional credibility shaping how effectively emerging economies balance growth with climate objectives.
