Carbon pricing does one deceptively simple thing: it puts a cost on pollution. It can reshape how economies manage growth, competitiveness, and fiscal resilience.
Across Europe and Central Asia (ECA), governments are navigating tightening fiscal space, weak productivity growth, and continued exposure to energy price shocks. External developments are compounding these pressures. From 2026, the European Union’s Carbon Border Adjustment Mechanism (CBAM) will apply a carbon price to selected imports, creating new adjustment risks for carbon-intensive sectors in the region.
These challenges are rooted in deeper structural constraints. ECA remains the most energy-intensive World Bank region, reflecting decades of underinvestment, distorted energy pricing, and aging capital stock. The result is higher emissions, elevated pollution, and persistent vulnerability to volatile energy markets. Combined with low tax-to-GDP ratios and limited fiscal buffers, these conditions point to the need for policy tools that can address multiple constraints at once.
These questions were central to discussions at the Vienna Development Knowledge Center (VDKC), which brought together policymakers and experts from across the region on May 5–6, 2026 for Navigating Global Tax Shifts: Regional Approaches for ECA Countries in Carbon Taxation.
Combining technical sessions with practitioner-led discussions, the workshop brought together perspectives from EU member states, accession countries, and neighboring economies. The exchange focused on carbon tax design, the implications of CBAM, complementary policies and the institutional requirements for implementation of carbon tax reflecting the shared but differentiated challenges across the region.
Carbon pricing as a development and fiscal tool
“Carbon pricing does one really simple thing: it puts a cost on pollution,” said Julian Lee of the World Bank’s Partnership for Market Implementation. But its implications go beyond climate policy. “We don’t really think of it just as a climate policy, but as a development policy,” he added, reflecting its role in shaping incentives, improving resource allocation, and supporting broader economic outcomes.
A consistent theme throughout the workshop was the need to balance competing objectives. Carbon pricing must raise revenue without undermining growth, incentivize cleaner production without imposing disproportionate burdens, and align domestic systems with evolving international frameworks. When well designed, it can support fiscal consolidation, enhance energy efficiency, and encourage investment in cleaner technologies. It also provides a mechanism to shift part of the tax burden away from labor while broadening the revenue base—an important consideration in countries where tax systems face structural limitations.
This emphasis on sequencing and equity ran through the discussions. Designing credible pricing pathways requires careful calibration of price signals, transparent use of revenues, and complementary measures to address distributional effects and competitiveness concerns.
Moving toward credible pricing pathways
As countries across the region respond to CBAM and broader decarbonization pressures, carbon pricing is likely to play an increasingly central role in economic adjustment. Credible systems—supported by robust monitoring frameworks and aligned with fiscal and industrial policy—can help reduce energy intensity, strengthen resilience, and support cleaner growth trajectories.
Moving from concept to implementation is complex. Some countries are advancing monitoring, reporting, and verification systems and introducing carbon-related taxes, while others are at earlier stages. Designing credible pricing systems requires strong institutional capacity, reliable data, and integration with energy and industrial policy frameworks.
“Designing a carbon pricing system is no simple task, and there is no one-size-fits-all solution,” said Dirk Heine, Lead Economist in the World Bank. Cross-country exchange allows governments to draw on practical experience and adapt approaches to national circumstances, helping to accelerate implementation. The challenge ahead lies not only in introducing carbon pricing, but in embedding it within coherent policy frameworks that support long-term development.
