Fiscal Decentralization and Environmental Sustainability

Fiscal decentralization refers to the transfer of revenue‐raising powers and expenditure responsibilities from central to subnational governments. In the environmental sphere, this institutional arrangement can enhance policy responsiveness, promote innovative local solutions and encourage stakeholder engagement. Theoretical debates centre on whether devolved fiscal authority fosters a “race to the top”, whereby jurisdictions compete to adopt stricter environmental standards, or a “race to the bottom”, in which regions lower regulations to attract investment. Empirical evidence reveals a nuanced picture: in some contexts, local autonomy has improved air quality and reduced carbon emissions through targeted spending on renewables and pollution control, while in others it has amplified interjurisdictional competition that erodes environmental safeguards. Spatial interdependencies further complicate outcomes, as pollution and policy impacts may spill across administrative borders. Global case studies—from rapidly urbanizing regions in Asia and Africa to established federal systems in Europe and Latin America—demonstrate that the design of fiscal transfers, performance assessment frameworks and regulatory oversight shapes whether decentralization advances or undermines sustainability goals. Practical applications include tailoring green investment incentives, deploying environmental fiscal transfers and calibrating local revenue‐expenditure balances to align economic growth with ecological protection. As nations pursue climate targets and sustainable development commitments, understanding the conditions under which fiscal decentralization supports environmental objectives has become a priority for both scholars and policymakers.

Technical terms

Fiscal decentralization: The allocation of revenue‐raising authority and expenditure responsibility from higher to lower levels of government.

Race to the top: A competitive dynamic in which jurisdictions strengthen environmental standards to gain social and ecological benefits.

Race to the bottom: A scenario in which regions weaken regulations to attract investment, often at the expense of environmental quality.

Environmental Kuznets curve: A hypothesised relationship in which environmental degradation first increases with income and later decreases as a society becomes wealthier and can invest in cleaner technology.

Spatial spillover effect: The phenomenon whereby policies, emissions or environmental outcomes in one jurisdiction influence neighbouring areas through economic, ecological or social linkages.
